What is Burn Rate?

Burn rate is a critical financial metric for startups, representing the rate at which a company consumes its cash reserves or venture capital to cover its operating expenses before achieving positive cash flow from operations. It is typically calculated on a monthly basis and is a direct indicator of a company's "negative cash flow." For example, if a startup has monthly operating expenses of ₹15 Lakhs (including salaries, rent, marketing, and servers) but only generates ₹5 Lakhs in revenue, its net burn rate is ₹10 Lakhs per month. Understanding burn rate is essential because it determines the company's "runway"—the number of months it can survive before it completely runs out of cash. Monitoring burn rate is a core responsibility for founders, as it informs critical decisions regarding cost-cutting, hiring, and the timing of the next fundraising round. High burn rates without corresponding growth in key performance indicators (KPIs) like revenue or active users are a major red flag for investors during due diligence. Conversely, an optimized burn rate suggests that the company is deploying capital efficiently to fuel growth. Mastering the management of your burn rate is the difference between building a sustainable business and facing a premature and avoidable failure. It is often segmented into "Gross Burn" (total monthly expenses) and "Net Burn" (expenses minus revenue).
