What Is Burn Rate?

Burn rate is the speed at which a company spends its available cash each month, usually before it becomes profitable.

Burn Rate Meaning

The burn rate, meaning, centres on cash consumption and survival. To define burn rate in practice, it is the difference between how much money a business earns and how much it spends over a fixed period, most commonly measured monthly. A clear burn rate definition helps founders understand how long their current cash will last, known as their runway. For investors, burn rate stands for financial discipline, showing whether growth is being funded sustainably or at risk of running out of capital too soon.
