Detailed Deep Dive

Burn Rate is the rate at which a startup spends its cash reserves, typically measured on a monthly basis. Gross burn rate represents the total monthly operating expenses, while net burn rate is the actual cash lost (operating expenses minus incoming revenue). A high net burn rate quickly depletes runway and is a key metric tracked by venture capitalists to evaluate operational efficiency, cost management, and overall financial health.
