Burn Rate & Runway Calculator
Calculate startup burn rate, runway in months, and 24-month cash projection. Includes burn multiple (David Sacks framework) and Default Alive / Dead status (Paul Graham YC framework). Built for Indian seed and Series A founders.
💰 Cash position + monthly flows
Enter today's cash balance and your monthly revenue / expense run rate. Indian seed benchmark: ~₹2 Cr raised, ~₹15-20 L monthly burn, ~24 months runway target.
Bank balance + bank-equivalent. Exclude receivables.
Cash-basis MRR. Use 0 if pre-revenue.
All-in: salaries + tools + ads + rent + tax.
Net new ARR added monthly — for the burn-multiple metric.
Series A healthy: 10-15% MoM. Compound effect over 24 months is enormous.
Hiring + tool stack growth. Most startups: 2-5% MoM.
✅ Healthy runway — plan next round
12-18 months is the standard Indian Series A runway. You're in the comfortable zone — next move is to start mapping which VCs you'll talk to and what your numbers need to look like at first call. The right time to start raising is when you have 12-15 months left; that gives you 3-4 months of process time and lands the wire with 6-9 months in the tank.
📅 24-month cash projection
Month-by-month projection assuming your MoM revenue and expense growth continue. The row where the cash balance turns red is the month you run out.

📊 Indian startup runway benchmarks
| Stage | Typical runway | Burn multiple target | Cash raised |
|---|---|---|---|
| Pre-seed / Angel | 12–18 months | N/A (pre-revenue) | ₹50 L – ₹3 Cr |
| Seed | 18–24 months | < 3.0 (early days) | ₹3 Cr – ₹10 Cr |
| Series A | 24–30 months | < 2.0 | ₹15 Cr – ₹50 Cr |

Benchmarks from Indian VC fund decks (3one4, Blume, India Quotient, Accel India, Peak XV) and the David Sacks "Burn Multiple" Series A framework. Bear-market rounds typically design for even longer runway (30-36 months) to skip a fundraise cycle.
📐 The exact formulas
Gross burn = Total monthly expenses Net burn = Monthly expenses − Monthly revenue Runway (months) = Current cash ÷ Net burn Zero-cash date = Today + Runway months Burn multiple = Net burn ÷ Net new ARR (same period) Default Alive (YC) = Will you cross break-even before cash runs out?
The two frameworks built into this calculator: Paul Graham's Default Alive vs Dead (YC 2015 essay) projects MoM revenue growth forward and asks whether you reach break-even before running out of cash. David Sacks' Burn Multiple (Craft Ventures 2020) divides net burn by net new ARR added in the same period — under 1.0 is "amazing", 1-2 "great", 2-3 "okay", and above 3 is "suspect". Both are the standard Indian VC questions at every board meeting.
❓ FAQs
What's the difference between gross burn and net burn?
Gross burn is your total monthly expenses — what leaves the bank account regardless of revenue. Net burn is gross burn minus revenue — how much cash you're actually losing. A SaaS with ₹15 L monthly expenses and ₹3 L MRR has a gross burn of ₹15 L but a net burn of ₹12 L. Indian VCs always ask for both — net for runway math, gross for cost structure understanding. If you only quote one, quote net.
What's a healthy runway for an Indian seed-stage startup?
18-24 months is the Indian seed-fund standard (3one4, Blume, India Quotient, Lightspeed seed). Most seed rounds in India are structured to give the founder exactly that — if you're raising ₹5 Cr at ₹20 L monthly burn, that's exactly 25 months of runway. Anything under 18 months at seed is considered "too tight" and forces a back-to-back Series A fundraise before the metrics have time to mature.
When should I start raising my next round?
When you have 9-12 months runway left. Indian VC processes take 3-4 months from first call to wire transfer (longer in bear markets). Below 9 months and you're negotiating from weakness — the "desperate founder" tax is real and typically costs 20-30% of valuation. Below 6 months and existing investors usually have to bridge you with a SAFE/CCD, which sets a punitive valuation floor for the next round. The rule: raise when you don't need to, not when you do.
What is the burn multiple and why does it matter?
The burn multiple (David Sacks, Craft Ventures 2020) is net burn ÷ net new ARR in the same period. It tells you how efficiently you're converting cash into recurring revenue. Sacks' bands: <1.0 amazing, 1-1.5 great, 1.5-2 good, 2-3 suspect, >3 bad. It became the dominant SaaS efficiency metric post-2022 when growth-at-all-costs fell out of favour. A startup with ₹12 L net burn adding ₹6 L of new ARR per month has a burn multiple of 2.0 — okay but worth optimising.
What is "Default Alive" vs "Default Dead"?
From Paul Graham's 2015 YC essay: a startup is Default Alive if, assuming current growth and expense trajectories continue, it reaches profitability before cash runs out. Default Dead means cash runs out first. The critical insight is that most founders don't know which side they're on — they assume "we'll raise" without checking the math. This calculator's 24-month projection shows you exactly which side of the line you're on, given your current numbers.
How do I cut burn quickly without killing growth?
Indian seed-stage burn typically sits in 3 buckets: (60%) salaries, (20%) ads, (10%) tools + cloud, (10%) rent + other. The fastest cuts: (1) pause all paid acquisition above your CAC payback threshold — usually 30-40% of ads spend is below the ROI line; (2) audit the tool stack — ~40% of SaaS tools at most startups are under-used; (3) move team to remote-first / hybrid and exit the lease at next break point; (4) defer hires by 90 days. These typically recover 25-40% of monthly burn without touching the growth motion.
Should I include founder salaries in burn?
Yes. If founders are drawing a salary (even a token ₹50 K/month), that's gross burn. Investors will ask. Indian seed-founders typically draw ₹25 K – ₹1 L per month; Series A founders draw ₹1.5 L – ₹3 L. The bigger question is whether founders are skipping salary entirely (capex-style equity-only mode) — that's not sustainable past 6-12 months and creates personal financial stress that distorts decision-making. Most India VCs actively encourage paying founders enough to remove the survival distraction.
What if my revenue is lumpy (annual contracts paid upfront)?
Use cash-basis MRR (annual contract value ÷ 12), not the upfront-payment spike. The cash spike improves your cash balance but doesn't change your underlying burn picture. Many Indian SaaS founders look at a bank balance spike and conclude they don't need to raise, then 6 months later realise they were paying out ₹15 L/mo against ₹2 L of monthly recognized revenue. This calculator assumes you've already smoothed annual contracts into monthly revenue.

Tips & Best Practices
Burn Rate & Runway Calculator for Indian Users
India's MSME sector — comprising over sixty-three million enterprises — is the economic backbone of the country, contributing nearly thirty percent of GDP and employing over eleven crore people. Yet most of these businesses operate with minimal formal financial planning tools. The average kirana shop, garment unit, food processing business, or service provider in India makes pricing and investment decisions based on experience and rough estimates rather than precise calculations. GST compliance alone has created an enormous demand for accurate tax computation tools, as businesses navigate multiple rate slabs and distinguish between CGST, SGST, and IGST. Burn Rate & Runway Calculator brings professional-grade business calculation capabilities to these enterprises for free. The tool understands Indian business context — GST structures, Indian accounting conventions, RBI lending frameworks, and MSME classification criteria. With India's startup ecosystem producing thousands of new businesses annually and the government actively promoting entrepreneurship through initiatives like Startup India, accessible business tools are more important than ever. Burn Rate & Runway Calculator ensures that a first-generation entrepreneur in a small town has the same calculation capabilities as a CA-advised business in a metro city.

Business tools on SabTools.in handle the small-business finance math that every founder, freelancer, and shopkeeper needs — GST invoices with correct CGST/SGST/IGST breakup, profit-and-loss on a given sales volume and cost structure, break-even analysis for a new product, ROI on a given investment horizon, home-loan affordability based on income and existing liabilities, rent-vs-buy analysis for the real-estate decision that every mid-career professional faces, and carpet-area vs super-built-up conversion for property purchases. These are the calculations that decide whether a business is viable, whether a home is affordable, and whether an investment is worth it. We build each as a single-purpose tool with Indian defaults — GST slabs (0%, 5%, 12%, 18%, 28%), Indian interest-rate bands for home loans (8-9.5% on floating rate in 2025), and the super-built-up-vs-carpet-area gap that the RERA Act 2016 regulates.
