Frequently Asked Questions
Burn rate is the monthly rate at which a company spends its cash. Gross burn is total monthly expenses. Net burn subtracts revenue — it is the actual monthly cash depletion. Runway = Cash ÷ Net Burn.
It depends on stage and funding. Early-stage startups often burn $50K-$200K/month. Series A companies $200K-$1M. The key question is not the absolute number but whether burn is proportional to growth and runway.
Look at your bank account balance at the start and end of the month. The difference (if lower) is your net burn. Or sum all cash outflows from your bank statement, then subtract all cash inflows from customers.
The biggest levers are typically headcount (50-70% of burn for most startups), followed by office space, cloud infrastructure, and marketing spend. Prioritize cuts that have the least impact on revenue generation.
Monthly minimum, weekly if runway is under 6 months. Track both gross and net burn. Compare month-over-month to catch unexpected increases early. Present to your board with a waterfall breakdown by category.
