Metrics

Burn rate

The rate at which a startup spends its cash reserves each month, before or after accounting for revenue.

Burn rate measures how quickly a startup consumes cash. There are two standard variants. Gross burn is the total cash spent in a month on all operating expenses — salaries, rent, cloud infrastructure, marketing, and so on. Net burn subtracts any revenue collected in that same month. If a startup spends ₹12 lakh and earns ₹4 lakh in a month, gross burn is ₹12 lakh and net burn is ₹8 lakh.

Investors scrutinise burn rate for two reasons. First, paired with cash on hand, it determines runway — the single most existential metric for an early-stage company. Second, the composition of burn reveals strategic intent: a startup burning heavily on engineering and product signals growth investment; one burning on founder salaries or office space raises efficiency concerns.

Burn rate is not inherently bad. High burn can be rational when it is funding growth that will generate returns exceeding the cost of capital. The red flag is burn that does not correlate with measurable output — declining revenue per rupee of burn, or a widening gap between spending and key performance indicators.

A useful derived metric is burn multiple, which divides net burn by net new ARR added in the same period. A burn multiple of 1x means the startup spends ₹1 to generate ₹1 of new annualised revenue. Efficient companies target below 1.5x; above 2x signals capital inefficiency that investors will probe in due diligence.

Frequently asked questions

Which burn figure should founders report to investors?
Report both. Gross burn shows total operational cost; net burn shows the real cash drain. Hiding one or the other creates mistrust — sophisticated investors will calculate both themselves.
What is burn multiple and why does it matter?
Burn multiple = net burn ÷ net new ARR. It measures how efficiently a startup converts spending into revenue growth. A lower number means less capital is required to achieve each unit of growth.
How can a startup reduce burn rate without harming growth?
The most effective levers are moving variable costs to performance-linked contracts, delaying non-critical hires, negotiating annual prepay discounts on software, and accelerating collections from customers.
