Startup Funding Requirement Model: How to calculate the right raise

The number on the “ask” slide is the most scrutinised figure in an Indian fundraise, and it is usually the least derived. Most founders reach it by multiplying current burn by 18 months and rounding up. That method ignores the month in which cash bottoms out, the working capital a growing business absorbs, and the cash that Indian company law and FEMA lock up between term sheet and allotment. This article shows how to build a startup funding requirement model that produces a defensible ask, ties it to a milestone, and survives an investor analyst rebuilding it line by line.

How do you calculate how much funding a startup needs?

Take the lowest point of cumulative cash in your monthly plan up to the milestone that unlocks the next round (the cash trough). Add working capital build, capex and deposits, a fundraise buffer of 6 to 9 months of post milestone burn, a minimum cash floor, transaction costs and a 10 to 15% contingency. Subtract existing cash and committed non dilutive money. The result is your funding requirement.

What is a startup funding requirement model?

A startup funding requirement model is a schedule, usually one tab sitting on top of your operating plan, that converts monthly cash flows into a single ask number and a use of funds split. It answers three questions: how much, until when, and to achieve what. It is narrower than a full financial model and more exact than a runway calculation.

The distinction matters because founders often treat these as the same artefact. A financial model projects the business. A runway calculation tells you how long current cash lasts (our burn rate and runway guide covers the formulas). The funding requirement model works in the opposite direction: it starts from where you need to be and solves for the cash required to get there with a safety margin.

Table 1: Where the funding requirement model sits among fundraise artefacts

Artefact	Question it answers	Time horizon	Primary reader
Runway calculation	How long does current cash last?	Today to cash out	Founder, board
13 week cash flow forecast	Can we meet obligations week by week?	3 months	Founder, finance team
Three statement financial model	What does the business look like over 3 to 5 years?	36 to 60 months	Investor analyst
Funding requirement model	How much must we raise, by when, for which milestone?	Today to next round close	Investor partner, founder
Use of funds schedule	Where will the raised money go?	Round deployment period	Investor, SHA covenant drafting

If you do not yet have a monthly operating plan, build that first; our financial modelling guide walks through the workbook. The funding requirement model reads from it and adds nothing to the revenue logic.

What must this round buy? Setting the milestone before the number

The funding requirement is the cost of reaching a specific, fundable milestone plus the cost of surviving until the next round closes. Every serious framework on round sizing, from operator blogs to VC needs analysis, starts here: you raise for milestones, not for months. A model without a dated, numeric milestone has no end point and no defence.

A fundable milestone has three properties:

• It is what the next investor buys. Ask two or three funds that lead the next stage what they look for, and write it down as a number. “Product market fit” is not a milestone. “₹1 crore MRR with net revenue retention above 110%” is.
• It is dated. The month you expect to hit it, derived from the operating plan, sets the model horizon.
• It moves valuation. Hitting it should support a next round priced meaningfully above this one. If the milestone does not change the story, the round is funding activity, not progress.

Table 2: Indicative milestone ladder for Indian venture rounds

Stage	What the round usually needs to prove next	Typical model horizon	Indicative round size in India (estimate)
Pre-seed	Working product, first users or pilots	12 to 18 months	₹1 to 5 crore
Seed	Repeatable early revenue, clear wedge	18 to 24 months	₹5 to 25 crore
Series A	Scalable channel, unit economics trending positive	18 to 24 months	₹40 to 150 crore
Series B	Efficient growth at scale, path to profitability	24 to 30 months	₹150 crore and above

Round sizes are Treelife practice ranges, not published data, and vary widely by sector; deep tech and fintech run larger, consumer services smaller. For the metrics Series A investors in India benchmark against, see our Series A fundraising playbook. This article takes the milestone as given and focuses on converting it into a number.

Why the “burn multiplied by 18” method undersizes Indian rounds

The multiplier method uses today’s burn, but burn in a funded plan is not flat. It rises as you hire against the new capital, and it peaks months before revenue catches up. A model that multiplies current burn by a fixed number of months will understate the requirement for any company planning to grow, which is every company raising venture money.

Four gaps appear repeatedly:

• Burn shape. Post round hiring pushes monthly burn up by 1.5x to 2.5x within two quarters in most seed to Series A plans we review (Treelife engagement observation, illustrative range, not a market benchmark). The cumulative deficit is driven by the peak, not the starting point.
• Working capital. Enterprise SaaS, B2B marketplaces and D2C brands carrying inventory absorb cash as revenue grows. A business with 75 days of receivables ties up roughly one fifth of annual revenue in debtors.
• Regulatory cash timing. Money from investors cannot be spent the day it lands. Under Section 42 of the Companies Act 2013, private placement money sits in a separate bank account until allotment (covered below).
• The next fundraise. You must reach the milestone with enough cash left to run a 6 to 9 month raise. The multiplier stops at the milestone; the months after it are where companies run out.

The fix is to model months, not multiples.

Inputs you need before building the funding requirement calculation

The funding requirement calculation depends on six input blocks. Each should trace to a source document or a stated assumption, because the investor analyst will ask for both.

1. Milestone definition. The metric and the month, as set out above.
2. Hiring plan. Role, month of joining, CTC, and employer cost loading. Since the four Labour Codes took effect on 21/11/2025, the wage definition rule (allowances above 50% of total remuneration are added back to wages) raises provident fund and gratuity cost for allowance heavy CTC structures. Rebuild employer cost on the new wage base rather than carrying old payroll ratios (Code on Wages 2019, Section 2(y); Code on Social Security 2020). Verify the state rules for your location before finalising.
3. Revenue and collection drivers. Bookings, billing frequency and days to collect. The model needs cash receipts, not revenue.
4. Non payroll operating costs. Cloud, marketing, rent, software, professional fees, by month and by actual payment timing (annual contracts paid upfront hit one month, not twelve).
5. One time spends. Capex, rental deposits, security deposits with marketplaces or payment gateways, licence fees, and any regulatory capital (see the sector section below).
6. Existing and committed sources. Bank balance, sanctioned but undrawn debt, sanctioned grant tranches, and signed but undrawn instruments.

Table 3: Input blocks, source documents and common errors

Input block	Source document	Common error	Effect on ask
Milestone	Investor conversations, board approved plan	Vague milestone (“product market fit”)	Ask cannot be defended
Hiring plan	Offer letters, org chart, salary benchmarks	Pre Labour Code PF and gratuity ratios	Understates payroll cost (size depends on CTC structure; estimate per company)
Collections	Contracts, debtor ageing	Revenue used in place of receipts	Understates working capital
Operating costs	Last 6 months of MIS	Annual contracts spread evenly	Misses cash peaks
One time spends	Quotes, lease deeds, regulator requirements	Deposits and regulatory capital omitted	Understates by full amount
Existing sources	Bank statements, sanction letters	Counting uncommitted debt or unsanctioned grants	Overstates available cash

How to build the startup funding requirement model, step by step

Build it monthly, from today to 6 to 9 months after the milestone month. Every row should be a live formula linked to the operating plan, so that changing a hiring date flows through to the ask.

Step 1: Lay out monthly net operating cash flow

Pull operating cash inflows and outflows from the plan into one row per month. Include GST paid on inputs you cannot yet set off, TDS, PF and ESI deposits on their due months, and advance tax instalments if you are profitable or earn taxable interest on treasury. These are not P&L costs, but they move cash in specific months. Our cash flow forecasting guide sets out the full India cash calendar; the funding requirement model only needs the monthly totals.

Step 2: Compute cumulative cash and find the trough

Run a cumulative sum of net cash flow starting from zero (exclude existing cash at this stage). The most negative value is the cash trough, and the month it occurs in is the trough month. This is the peak funding requirement before buffers.

For most growth plans the trough falls at or just after the milestone month. If it falls much later, the plan does not reach break even within the horizon and the buffer in Step 4 carries more weight.

Step 3: Add working capital, capex, deposits and regulatory capital

Add the incremental investment in receivables and inventory up to the trough month, net of payables. Add capex, deposits and any minimum net worth the business must hold in the month they fall due. Keep these as separate rows so the use of funds schedule can show them distinctly; investors read a working capital line differently from a marketing line.

Step 4: Add the fundraise buffer and minimum cash floor

Add the net burn expected in the 6 to 9 months after the milestone. Indian Series A processes, from first meeting to money in bank, commonly run 4 to 9 months (Treelife engagement observation; no official dataset exists, treat as an estimate), and diligence, FEMA pricing and allotment add weeks at the end. Add a minimum cash floor, usually one to two months of payroll, below which the board should not let the balance fall. Venture debt lenders often set a covenant at a similar level.

Step 5: Add transaction and regulatory costs

Stamp duty on issue of shares is 0.005% of the issue value under the Indian Stamp Act 1899 as amended by the Finance Act 2019 (effective 01/07/2020). Add MCA filing fees for any increase in authorised capital (Form SH-7, fees under the Companies (Registration Offices and Fees) Rules 2014), registered valuer fees, legal fees for the term sheet, SSA and SHA, and diligence support costs. On a ₹15 to 20 crore round these typically total ₹15 to 40 lakh (estimate; replace with your quotes). There is no GST on the issue of shares, but GST at 18% applies to the advisory and legal fees.

Step 6: Add contingency and net off existing sources

Apply a 10 to 15% contingency on the operating deficit (not on the buffer, or you double count). Then subtract cash in bank and committed sources. The result is the funding requirement. Round it to a number that maps cleanly to a valuation and dilution band (see round sizing below).

Step 7: Run scenarios and lock the number

Run the model under a base case and at least one downside, and set the ask so that the downside still reaches the milestone with a reduced, but positive, buffer. The scenario section below shows how.

Need the model tied to your projections deck before investor meetings? Our guide on investor pitch financial projections preparation covers how the ask, the projections slide and the valuation inputs must carry identical numbers.

Funding requirement model template: tabs, rows and formulas

A clean template has five tabs and no hard coded totals. Investors open the formulas before they read the numbers, so structure matters as much as output.

Table 4: Funding requirement model template structure

Tab	Contents	Key formula logic	Links to
Inputs	Milestone, month, buffer months, contingency %, cash floor, transaction cost estimate, scenario switch	Named ranges for every assumption	All tabs
Monthly cash	Operating receipts, payroll, opex, statutory dues, working capital, capex, deposits	Pulls from operating plan by month	Operating plan
Requirement	Cumulative cash, trough, buffer, floor, transaction, contingency, sources	Trough: MIN of cumulative cash row; trough month: MATCH of that minimum	Monthly cash, Inputs
Sources and uses	Equity, debt, grants, existing cash against each use bucket	Sources must equal uses; check cell returns zero	Requirement
Dilution	Ask, pre money range, ESOP pool top up, founder and investor post round holding	Post money equals pre money plus primary raise	Cap table

Two checks belong on the Requirement tab: sources minus uses equals zero, and the month end cash balance after funding never falls below the cash floor. Conditional formatting that turns a month red when it breaches the floor is the fastest way to show an investor the plan holds.

Worked example: peak funding requirement for a B2B SaaS company

A Bengaluru B2B SaaS company has ₹2 crore in the bank, current net burn of ₹50 lakh per month, and a milestone of ₹1 crore MRR by month 18. Venture debt of ₹2 crore is sanctioned and undrawn. The figures below are illustrative.

Table 5: Funding requirement build, illustrative (₹ crore)

Component	Basis	Amount	Use of funds bucket
Cumulative operating deficit to trough	Monthly plan, trough at month 18	11.50	Team, product, go to market
Working capital build	75 day DSO on growth in billing	1.20	Working capital
Capex and deposits	Laptops, office deposit	0.60	Capex
Statutory cash timing	Labour Code gratuity provisioning, GST on imported SaaS under reverse charge	0.40	Operations
Fundraise buffer	6 months of post milestone net burn at ₹80 lakh	4.80	Runway buffer
Minimum cash floor	About 1.5 months of payroll	0.50	Runway buffer
Transaction costs	Stamp duty, valuer, legal, MCA	0.25	Transaction
Contingency	10% of operating deficit	1.15	Contingency
Gross requirement		20.40
Less: cash in bank		(2.00)
Less: committed venture debt		(2.00)
Funding requirement		16.40

The multiplier method gives ₹50 lakh × 18 = ₹9 crore. The trough method gives ₹16.4 crore. A founder who raises ₹9 crore runs out of cash around month 13, five months before the milestone that was meant to fund the next round. That is the structural reason so many Indian seed companies end up raising bridge rounds at flat or lower valuations.

How sensitive is the ask? Scenario and sensitivity testing

A funding requirement is only as good as its worst plausible case. Investors will stress the plan anyway; doing it first lets you set an ask that survives their downside rather than renegotiating after diligence. Test the variables that move cash most, one at a time, then together.

Table 6: Sensitivity of the illustrative ₹16.4 crore requirement

Variable flexed	Change tested	Approximate change in requirement (₹ crore)	What to do if it bites
Revenue ramp	25% lower collections each month	+2.5 to +3.0	Slow hiring behind revenue triggers
Hiring timing	All hires 2 months earlier	+1.0 to +1.5	Tie hires to milestones in the plan
Collections	DSO from 75 to 105 days	+0.5 to +0.7	Move to annual upfront billing
Round close	Usable cash 3 months later	+1.5 to +2.0 (pre round burn from existing cash)	Line up venture debt or an insider bridge
Combined downside	Revenue 25% lower and close 3 months later	+4.0 to +5.0	Smaller milestone or tranche structure

Figures are illustrative outputs of the worked example, not benchmarks. The practical rule: if the combined downside exhausts more than half of the buffer, either raise more or define a smaller milestone. A plan that only works in the base case is the most common reason an analyst cuts the ask or the valuation.

Run one more test: is the company “default alive”? Hold revenue at the downside, freeze hiring at month 6, and check whether cash reaches break even before it hits zero. If it does, you can present the buffer as optional; if not, the buffer is essential and should be defended as such.

What India specific factors change the funding requirement?

Indian company law, FEMA, sector regulation and tax rules affect when raised money can be used, what it costs to receive, how much capital must be held idle, and how the round interacts with tax losses. A model that ignores them understates the ask or overstates available cash in the first quarter after close.

Section 42 and Section 62 lock up investor money until allotment

A private placement under Section 42 of the Companies Act 2013, read with Rule 14 of the Companies (Prospectus and Allotment of Securities) Rules 2014, requires subscription money to be kept in a separate bank account. It can be used only for adjustment against allotment or for refund. Allotment must happen within 60 days of receipt; if not, the money must be refunded within 15 days after that, failing which it carries interest at 12% per annum from the 60th day. The return of allotment (Form PAS-3) is due within 15 days of allotment.

For the model, a money in date of month N is a usable cash date of month N or N+1 at best, and later if the board meeting, valuation report or shareholder approval slips.

FEMA timelines apply to foreign investors

Where any investor is a non resident, the Foreign Exchange Management (Non-debt Instruments) Rules 2019 require the issue price to be not less than fair value and the capital instruments to be issued within 60 days of receipt of consideration, with refund within 15 days thereafter if not issued. Form FC-GPR must be filed with the Reserve Bank of India (RBI) within 30 days of issue (Foreign Exchange Management (Mode of Payment and Reporting of Non-Debt Instruments) Regulations 2019); our FC-GPR filing guide covers the process.

If any investor has beneficial ownership in a country sharing a land border with India, Press Note 3 (2020) routes the investment through government approval, which can add months. Press Note 3 has seen recent amendment; check the current text on the Department for Promotion of Industry and Internal Trade (DPIIT) site before you fix a close date in the model.

Labour Code wage cost and statutory dues

As noted in the inputs section, the post 21/11/2025 wage definition changes employer PF and gratuity cost. Model gratuity as a provision and as a cash outflow at expected exits, not as a percentage nobody pays until year five. Model TDS, PF, ESI and GST on their actual due months.

Sector regulatory capital is a funding requirement line

Regulated businesses must hold minimum net worth or capital that cannot be spent on growth. It belongs in the requirement as a separate, non deployable line.

Table 7: Regulatory capital items that sit inside the ask (verify before use)

Business	Requirement	Source	Model treatment
Payment aggregator	Net worth of ₹15 crore at application and ₹25 crore by end of the third financial year	RBI guidelines on payment aggregators (17/03/2020), now consolidated in RBI directions; verify current text	Hold as minimum equity; exclude from deployable cash
NBFC (investment and credit company)	Net owned fund of ₹10 crore by 31/03/2027 under scale based regulation	RBI circular on scale based regulation (22/10/2021); verify current master direction	Phase per glide path
Hardware or manufacturing	Tooling, certification, inventory	Commercial, not regulatory	Capex and working capital rows
Marketplace or D2C	Security deposits with platforms and payment gateways	Platform terms	Deposits row

Thresholds are as last published; RBI has been consolidating its directions, so confirm the current master direction before relying on these numbers. Hardware companies face a different sequencing problem; our note on hardware R&D startup fundraising covers milestone linked tranches and grant sequencing.

Tax losses and the shareholding change test

Losses carried forward can lapse when shareholding with voting power changes beyond 49%, under Section 79 of the Income-tax Act 1961, with a relaxation for eligible DPIIT recognised startups. From 01/04/2026 the Income-tax Act 2025 governs tax years 2026-27 onwards, with losses computed under the 1961 Act carried forward through the transition provisions in Section 536. A large round that crosses the 49% line can raise the effective tax cost in later years of the plan. Confirm the corresponding section under the 2025 Act and your DPIIT eligibility before relying on the losses; our note on how a funding round can kill carry forward losses covers the test.

Valuation no longer carries angel tax risk, but pricing rules still bite

Section 56(2)(viib) of the Income-tax Act 1961 (angel tax) was omitted by the Finance (No. 2) Act 2024 for assessment year 2025-26 onwards. The ask no longer needs to be sized around a defensible income tax valuation ceiling. FEMA fair value floors for non resident investors, and the registered valuer requirement for preferential allotment under Section 62(1)(c) read with Rule 13 of the Companies (Share Capital and Debentures) Rules 2014, still apply.

Currency and treasury on the money you raise

If the round is priced in US dollars, the rupee amount you receive depends on the exchange rate on the remittance date. Model the ask in rupees, show the dollar equivalent at a stated rate, and keep a small FX cushion if the gap between term sheet and remittance is long. Interest earned on parked funds in fixed deposits or liquid funds is taxable income and is often restricted by the SHA’s investment policy; treat it as upside, not as a source that reduces the ask.

Table 8: Regulatory timing and cost items to load into the model

Item	Rule	Model treatment	Typical effect
Separate bank account until allotment	Section 42, Companies Act 2013; Rule 14, PAS Rules	Delay usable cash to allotment month	2 to 8 week lag (estimate)
Allotment within 60 days	Section 42(6); NDI Rules 2019	Refund risk row if close slips	Interest at 12% p.a. if refund late
Form FC-GPR	FEMA reporting regulations 2019	Compliance cost row	Late submission fee if missed
Stamp duty on issue	Indian Stamp Act 1899, as amended 2019	0.005% of issue value	₹10,000 per ₹2 crore issued
Press Note 3 approval	FDI policy, DPIIT	Shift close date for affected investors	Months, case specific
Labour Code wage base	Code on Wages 2019; Code on Social Security 2020	Rebuild employer cost	Higher PF and gratuity outflow

Which non dilutive and debt sources reduce the equity ask?

Only committed money reduces the funding requirement. A sanctioned loan, a signed grant agreement or an executed debt term sheet can be netted off; an application or a lender’s interest cannot. Show each source on its own row with the month it becomes usable, because most arrive in tranches.

Table 9: Sources that can be netted off the requirement

Source	Key terms	Status as of 2026	Net off only when
Venture debt	Commonly 20 to 35% of the last equity round (market observation, estimate), with warrants and covenants	Active market	Term sheet executed and conditions to drawdown are within your control
Credit Guarantee Scheme for Startups (CGSS)	Guarantee cover per borrower raised from ₹10 crore to ₹20 crore; 85% of default covered for loans up to ₹10 crore, 75% above	Revised by DPIIT notification of 09/05/2025	Loan sanctioned by a lender under the scheme
Startup India Seed Fund Scheme (SISFS)	Up to ₹20 lakh grant and ₹50 lakh convertible or debt, via incubators, in milestone tranches	Corpus fully committed to 219 incubators; scheme extended for disbursement of approved support; check the portal for any new window	Sanction letter received; only the undisbursed tranches you expect to unlock
Sector grants (BIRAC BIG, state schemes)	Milestone linked, utilisation certificates required	Scheme specific	Grant agreement signed
Customer advances	Annual upfront billing, implementation fees	Contractual	Billed in the plan from signed contracts

Sources: CGSS revision as reported on DPIIT’s notification of 09/05/2025; SISFS status per Ministry of Commerce and Industry release of April 2026. For venture debt covenants and warrant cost, see our comparison of venture debt and equity funding. Grant money carries reporting obligations; our note on BIRAC BIG grant utilisation certificates explains what lenders and investors check.

Sources and uses: keep primary and secondary apart

The funding requirement covers primary money only, meaning money that comes into the company. If the round includes a secondary component, where investors buy existing shares from founders, angels or employees, that money goes to the sellers and does nothing for the company’s cash trough.

Present a sources and uses table with two clearly separated halves. The primary half reconciles to the funding requirement. The secondary half shows who sells and how much, which matters for the cap table and for tax: a buyer paying a non resident seller has withholding obligations under the income tax law, and the price must respect FEMA pricing rules. Mixing the two inflates the apparent ask and confuses the analyst about how much runway the round actually buys.

Round sizing: connecting the funding requirement to valuation and dilution

Round sizing is the step where the funding requirement meets the market. The model gives you a cash number; the round must also land in a dilution band investors and founders will accept. If the two conflict, change the plan, the milestone or the instrument, not the arithmetic.

At seed and Series A, Indian rounds commonly dilute 15 to 25% (market practice range, not a regulatory figure). A widely used shortcut follows from this: the post money valuation is roughly 4 to 6 times the amount raised. Divide the requirement by the target dilution to see the valuation the ask implies.

Table 10: Implied post money valuation for a ₹16.4 crore requirement

Target dilution	Implied post money (₹ crore)	Implied pre money (₹ crore)	Read
15%	109.3	92.9	Needs strong traction evidence
20%	82.0	65.6	Typical Series A band
25%	65.6	49.2	Acceptable if the milestone is high conviction
30%	54.7	38.3	Signals the plan should shrink or split

If the implied valuation is out of reach, four levers reduce the equity ask without starving the plan:

• Tranche the round. Commit the full amount but release the second tranche on a defined milestone. The model then shows two money in dates and two troughs. Tranche conditions go into the SSA and must be measurable from MIS.
• Add venture debt or CGSS backed credit. Debt reduces dilution but adds repayment to the cash plan; model the EMIs in the monthly cash tab, not just the inflow.
• Pull the milestone forward. A smaller, earlier milestone shortens the horizon and lowers the trough.
• Cut the buffer, knowingly. Only where an insider has committed to a bridge, and only with the board’s sign off minuted.

If the term sheet requires an ESOP pool top up in the pre money, founders absorb that dilution; model it in the dilution tab. Our ESOP pool size calculation shows how much a pre money pool costs founders, and our explainer on equity dilution in India covers the mechanics.

Is it a problem to raise too much money?

Yes, past a point. Raising well above the funding requirement means selling more of the company at today’s lower price, and it raises the valuation bar for the next round. If the next round must be priced above this one and the business has not grown into the larger post money, the company faces a flat or down round, which can trigger anti-dilution adjustments in investors’ favour. Excess cash also loosens cost discipline; plans tend to expand to fit the money.

Raising too little carries the opposite risk: the company reaches the trough before the milestone and must bridge from a weak position, often on convertible terms with discounts that cost more dilution than a properly sized round would have. The funding requirement model exists to find the number between these two failures. A practical band is the requirement itself at the bottom and the requirement plus one extra quarter of post milestone burn at the top; anything beyond needs a specific reason, such as a competitor raising heavily in the same category. For how anti-dilution protection works in a down round, see our note on full ratchet versus weighted average anti-dilution.

How to present the use of funds schedule to investors

The use of funds schedule is the funding requirement model reorganised by bucket instead of by month. It should reconcile exactly to the ask and to the model, because the SHA often turns it into a covenant: many investor rights clauses require board or investor consent to deviate materially from the approved use of funds.

Present it in three layers:

1. Slide level: four to six buckets with percentages (team, product, go to market, working capital, buffer, transaction and contingency). No line items.
2. Summary tab: each bucket split into its main drivers, with the milestone each bucket buys.
3. Model level: the monthly schedule, with every number linked to the operating plan.

Keep the buffer and contingency visible as their own buckets. Hiding them inside “team” or “marketing” makes the plan look aggressive and invites an analyst to cut them. Showing them openly with a stated basis (6 months of post milestone burn, 10% contingency) almost always survives the conversation.

Ask for a single number, not a range. A range invites investors to anchor at the bottom, and it signals that you have not done the arithmetic. If you will accept a smaller first close, say so separately as a minimum close amount, backed by a reduced plan that still reaches a milestone.

After the round closes, the same schedule becomes the baseline for monthly reporting. Track actual spend against each bucket and explain variances in the board pack; our guide to MIS setup after a funding round covers the reporting format investors expect.

Preparing a data room alongside the model? Our secretarial documents checklist for a funding round data room lists what investors request alongside the financials.

What should you do if the round slips or closes short?

Re-run the model the day the timeline changes. A slip of three months consumes three months of pre round burn from existing cash and pushes the trough earlier; a short close lowers the cash available to reach the milestone. In both cases the model tells you how many months you have and which spends must move.

The usual responses, in order of cost:

1. Cut or defer spend that does not drive the milestone, and re-date hires.
2. Draw committed debt earlier, if covenants allow.
3. Raise an insider bridge on convertible terms. Convertible notes issued by DPIIT recognised startups must be for ₹25 lakh or more in a single tranche and convertible or repayable within 10 years to stay outside the deposit rules (Companies (Acceptance of Deposits) Rules 2014, Rule 2(1)(c)(xvii)). Our comparison of a bridge round versus a priced round covers the dilution cost.
4. Redefine the milestone to one the reduced cash can reach, and tell investors early.

Common mistakes that cost founders time and money

1. Sizing from current burn. It happens because current burn is the only number the founder fully trusts. It understates the ask whenever the plan involves hiring. Build the month by month trough instead.

2. Treating revenue as cash. It happens because the plan is built on a P&L. Annual upfront billing helps and 90 day enterprise terms hurt, and the difference can exceed ₹1 crore on a ₹10 crore ARR business. Model receipts from billing terms and actual debtor ageing.

3. Assuming money is usable on the term sheet date. Diligence, definitive agreements, valuation, shareholder approval, the Section 42 separate account and FEMA allotment rules sit between term sheet and usable cash. Model usable cash from the expected allotment month, and keep two months of cost cover for slippage.

4. Leaving out the next raise. Founders stop the model at the milestone. The months after it, during which you are pitching but not yet funded, are the most dangerous. Carry the model 6 to 9 months past the milestone.

5. Netting off money that is not committed. A grant application, a lender’s indicative interest or a scheme whose application window has closed is not cash. Net off only sanctioned or executed sources, by the month they become usable.

6. Double counting contingency. Adding 15% on the total, including the buffer, inflates the ask and invites pushback on the whole model. Apply contingency only to the operating deficit.

FAQs on startup funding requirement models

Q: How much should a startup raise in India?

A: Enough to reach the milestone that unlocks the next round, plus 6 to 9 months of buffer. Derive it from the cash trough in a monthly plan, add working capital, transaction costs and contingency, and net off committed sources. Rules of thumb such as burn × 18 understate growth plans.

Q: Is the funding requirement the same as the round size?

A: Not always. The funding requirement is the cash you need; the equity round is what remains after netting venture debt, existing cash and non dilutive sources. A ₹20 crore requirement can be a ₹16 crore equity round plus ₹4 crore of debt.

Q: How many months of runway should a funding requirement model cover?

A: To the milestone plus 6 to 9 months. Indian rounds from first meeting to allotment commonly take 4 to 9 months (estimate), and the model must cover that period after the milestone is reached.

Q: Does angel tax still affect how much a startup can raise?

A: No, for assessment year 2025-26 onwards. Section 56(2)(viib) of the Income-tax Act 1961 was omitted by the Finance (No. 2) Act 2024. FEMA fair value rules and registered valuer requirements still apply.

Q: Can a startup use investment money before shares are allotted?

A: No. Under Section 42 of the Companies Act 2013 and Rule 14 of the PAS Rules, private placement money stays in a separate bank account until allotment and can only be used for adjustment against allotment or refund.

Q: What happens if allotment is delayed beyond 60 days?

A: The company must refund within the next 15 days, failing which interest at 12% per annum runs from the 60th day (Section 42(6), Companies Act 2013). For non resident investors, the NDI Rules 2019 carry a parallel 60 day issue and 15 day refund window.

Q: How long does it take to build a funding requirement model?

A: Two to four weeks if a monthly operating plan and 6 months of clean MIS exist. Add two weeks if the plan has to be built from scratch.

Q: What documents are needed to build the model?

A: Bank statements, the last 6 months of MIS, the hiring plan with CTC structures, customer contracts showing billing terms, lease deeds, vendor quotes for capex, debt sanction letters and any grant agreements.

Q: How does a foreign investor change the funding requirement?

A: It shifts timing and adds cost. FEMA pricing, FC-GPR reporting within 30 days of issue, Press Note 3 approval where applicable and FX movement on a dollar priced round can push usable cash later or lower, which raises the buffer the model needs.

Q: Can CGSS backed loans or SISFS money reduce the equity ask?

A: Yes, once sanctioned. CGSS now guarantees loans up to ₹20 crore per borrower (DPIIT, 09/05/2025). SISFS can be netted only for sanctioned, undisbursed tranches; its corpus is fully committed, so check the portal before assuming a new window.

Q: Should co-founder salaries be included at market rates?

A: Yes, from the month the plan says they move to market. Investors will model it regardless, and a plan that depends on founders staying underpaid through the milestone reads as an understated ask.

Q: Does DPIIT recognition change the funding requirement?

A: It can, through tax. Eligible DPIIT recognised startups have a relaxation from the 49% shareholding change test on carry forward losses, so a large round may not wipe out losses that reduce future tax outflow.

Q: What if the round closes smaller than the funding requirement?

A: Re-run the model with the actual amount, find the new trough month, and cut or defer spend to restore a positive buffer. If that is not possible, redefine the milestone or arrange an insider bridge before deploying funds.

Q: Should a secondary sale be included in the funding requirement?

A: No. Secondary money goes to selling shareholders, not the company. Show it separately in the sources and uses statement; it affects the cap table and the buyer’s withholding obligations, not the cash trough.

Q: Should tranche conditions appear in the model?

A: Yes. Model each tranche as a separate money in date with the milestone that triggers it, and show the cash trough before each tranche. If cash before tranche two falls below the floor, the tranche split does not work.
