Cash Burn, also known as Burn Rate, refers to the rate at which a company spends its cash reserves to cover operating expenses when it is not yet generating positive cash flow. It is a crucial metric for startups and early-stage companies that rely on external funding to run their business.
Example: If a startup spends ₹10 lakh per month on all expenses, its gross burn rate is ₹10 lakh.
Formula: Net Burn = Cash Outflows – Cash Inflows
Example: If monthly expenses are ₹10 lakh and revenue is ₹3 lakh, net burn = ₹7 lakh/month.
To find out how long a company can keep operating:
Cash Runway = Cash Reserves ÷ Net Burn Rate
Example:
If a startup has ₹70 lakh in the bank and a net burn of ₹7 lakh/month:
Runway = 70 ÷ 7 = 10 months
Cash burn is a key metric investors evaluate before funding. A high burn rate with no clear path to revenue can raise red flags. On the other hand, a controlled burn with a good growth plan shows discipline and planning.
Startups in India, especially in sectors like edtech, fintech, and e-commerce, often have high burn rates in the initial years. News reports regularly highlight companies “burning cash” to gain market share through discounts, advertising, and expansion.
