Startup & Business Calculators
Free calculators built for Indian founders and SMEs — figure out your runway, model equity dilution, estimate tax savings and setup costs, then find the grants that fit.
Funding & equity
Work out how many months of cash you have left at your current burn — and when you need to start your next raise. Net burn accounts for any monthly revenue.
Check whether angel tax applies to your round. Section 56(2)(viib) no longer applies to shares issued from 1 April 2024; for older rounds, see the premium over FMV that the old rule looked at.
A back-of-the-envelope valuation based on your revenue, growth rate, sector and stage. Revenue-multiple approach with sector-specific ranges — a starting point for fundraising.
Model how a SAFE note converts at your next priced round. Compare the valuation cap and discount scenarios side by side — and see what the founder dilution looks like.
See how each funding round and ESOP top-up dilutes founder ownership. Add as many rounds as you like — investor and ESOP percentages are taken on the post-money company.
Know what you'll own before you sign. Add your founders, any SAFEs and convertible notes, and the priced round you expect. See who owns what afterwards, and how each SAFE and note converts. Your numbers stay in your browser.
Know what that 12% really costs. Enter two or three offers and get one all-in yearly cost for each, counting upfront fees, GST on fees, the final payment and warrants. Your numbers stay in your browser.
Model how a convertible note converts — principal plus accrued interest, the valuation cap and discount rate, and the resulting ownership for the note holder at your next round.
Tax & exemptions
DPIIT-recognised startups can claim a 100% profit deduction for any 3 consecutive years out of their first 10. Estimate how much income tax that saves you.
Estimate your income tax under any corporate regime — 22% (Sec 115BAA), 25% (turnover ≤ ₹400 Cr) or 30% standard. Full breakdown including surcharge and health & education cess.
Compare your tax under the regular GST scheme vs the composition scheme. Enter your turnover, GST rate and input credits to see which regime saves you more — and why.
Work out how much input GST you can actually claim. Account for exempt supplies, personal use, composition purchases and blocked credit to see your eligible ITC.
Check whether MAT applies to your company, what you pay all-in, whether any MAT credit arises under the Finance Act 2026 rules, and whether the 115BAA exemption applies to you.
See the tax DPIIT recognition saves you through Section 80-IAC, net of the MAT or AMT you still pay. Angel tax was abolished for share issues from 1 April 2024, so it no longer adds to the saving.
ESOPs are taxed twice — once at exercise (perquisite, at slab rate) and again at sale (capital gains). See both, plus your net proceeds, for listed or unlisted shares.
Operations
Estimate what it costs to incorporate in India — with typical stamp duty for your state and authorised capital, plus digital signatures and professional fees. Government fee is nil up to ₹15 lakh capital for a company; an LLP pays ₹500 to ₹5,000.
Professional tax per employee by state, using each state's own slab — monthly, half-yearly or annual — with the ₹2,500 yearly ceiling and your total liability.
Know your numbers: gross margin, contribution margin, LTV, CAC, LTV:CAC ratio, payback period, and the customer base needed to break even. Investor-ready unit economics in seconds.
Payroll
See the true cost of your team — CTC plus employer statutory contributions. Factor in PF (13% of basic), ESI, gratuity provision and bonus to understand your real payroll burden.
Compare the total cost of hiring as an employee (salary + PF + ESI + gratuity + bonus) vs a freelancer (invoice + TDS). See the statutory burden and non-financial trade-offs.
Calculate gratuity payable — (Basic + DA) × 15/26 × years of service — with the ₹20 lakh statutory cap and tax-exempt amount under Section 10(10).
Compliance
Work out the cost of a late GST return: 18% a year interest on tax paid late, plus the ₹50 a day GSTR-3B late fee (₹20 for nil) with its cap by turnover. Includes the January 2026 cash-ledger credit.
Work out TDS interest on late deduction (1% a month) and late payment (1.5% a month), plus the ₹200/day late fee for a late TDS return, which never exceeds the TDS.
Calculate the MCA late fee for delayed annual filing — AOC-4 (financial statements) and MGT-7 (annual return) — at ₹100 per day for each form.
Pre-flight check for DPIIT recognition. See if your startup meets all five criteria — entity type, age, turnover, innovation, and not formed by splitting an existing business.
See if your startup qualifies for SISFS — up to ₹20 lakh grant plus ₹50 lakh convertible debt. Checks DPIIT recognition, incorporation age, prior government support, and tech component against the published criteria.
Missed the income tax return due date? Work out the section 234F late fee and the 1% a month section 234A interest on the tax you still owed.
Check the interest for paying advance tax short or late: section 234C on every instalment (15%, 45%, 75%, 100%) and section 234B on the year-end shortfall.
Paid PF or ESI after the 15th? Work out the 12% a year interest and, for PF, the 1% a month damages that apply to contributions due from June 2024.
Filed LLP Form 11 or Form 8 late? Work out the additional fee, which since April 2022 is a multiple of the normal fee that grows with the delay.
