How This Calculator Works
This burn rate calculator tracks two critical metrics for any cash-consuming business. Gross burn rate is simply your total monthly operating expenses — every dollar going out the door.Net burn rate subtracts any monthly revenue from gross burn to show the true rate at which cash is depleted. Most investors focus on net burn when evaluating a company's financial health.
Runway is calculated as Starting Cash ÷ Net Burn Rate. The month-by-month chart shows your projected cash balance declining each month, with a dashed red line at the point where cash reaches zero. This makes it easy to visualize urgency and see the effect of cost cuts or revenue gains on your survival horizon.
If your monthly revenue meets or exceeds expenses, the calculator switches to a "Profitable — No Burn" state, showing your net monthly surplus instead of a countdown. Use this tool monthly to track runway trends, inform fundraising timing, and manage spending decisions against your cash position.
