Burn rate is the speed at which a startup consumes its cash. For SaaS companies especially, understanding burn rate is existential — it determines how long you have to find product-market fit, how efficiently you're deploying capital, and what story you're telling investors. Investors don't just look at your burn; they look at what you're getting for it.
The Burn Rate Formula
Gross Burn = Total Monthly Expenses. This includes everything: payroll, cloud infrastructure, marketing, office, SaaS tools, contractor fees, and legal. Nothing is excluded.
Net Burn = Gross Burn − Monthly Revenue (MRR). Net burn is the actual cash you're losing every month. It's the number that drives your runway calculation. A company with ₹20 lakh in gross burn and ₹8 lakh in MRR has ₹12 lakh in net burn — and that's the number that matters for survival.
The Burn Multiple: Capital Efficiency
The Burn Multiple, coined by David Sacks, measures how many rupees of burn it takes to generate one rupee of net new ARR. Formula: Burn Multiple = Net Burn ÷ Net New ARR.
Benchmarks: Under 1× is exceptional. 1–1.5× is good. 1.5–2× is acceptable early stage. Above 2× is a warning sign. Above 3× is a crisis. In the current environment, investors scrutinize this metric heavily. High burn multiples don't just mean you're inefficient — they mean your growth is fragile and likely to collapse when spending slows.
Category Breakdown: Where Does Startup Money Actually Go?
Typical SaaS startup burn breakdown: Personnel 60–70% (salaries, benefits, equity). Infrastructure 8–15% (cloud, CDN, databases). Sales & Marketing 10–20% (ads, tools, events, SDR cost). G&A 5–10% (legal, accounting, office, insurance). R&D tooling 2–5% (licenses, dev tools).
The personnel percentage is why layoffs are the fastest path to extending runway. But cuts have compounding costs: reduced morale, slower execution, potential customer impact. The best operators find 15–20% savings through vendor renegotiations, infrastructure optimization, and marketing channel efficiency before touching headcount.
Burn Rate Benchmarks by Stage
Pre-seed (< $1M raised): ₹5–15 lakh/month net burn. Anything above ₹20 lakh at this stage is a red flag unless you have strong revenue traction.
Seed ($1–3M raised): ₹15–50 lakh/month. You're hiring your founding team and establishing go-to-market. Spending should be producing measurable outputs: user growth, early revenue, product milestones.
Series A ($5–15M raised): ₹50–2 crore/month. You've found product-market fit and you're scaling what works. High burn is acceptable if the burn multiple is under 1.5× and your ARR growth rate is 100%+.
Burn rate isn't just a financial input — it's a signal about your strategic clarity. Teams with focused, efficient burn have usually made hard choices about what not to do.
