Burn rate is how much cash a company spends each month, and runway is how many months that cash will last before it runs out. For any startup living on savings or investment, these two numbers decide how much time you have to reach profitability or raise more money. This calculator takes your cash on hand, your total monthly expenses and any monthly revenue, then computes net burn as expenses minus revenue and divides your cash by that net burn to show runway in months. If you are already profitable the tool tells you the runway is effectively unlimited. Founders check burn and runway constantly to time fundraising and to decide when to cut costs. Enter your three figures and both results update instantly, so you always know your deadline. All calculations run locally in your browser, keeping your financials private.
