Cash Runway Calculator
ForecastingHow many months of cash you have — counted the way a CFO would. Set your cash on hand, what you collect, and your monthly burn, and it solves runway both ways: the flat-burn number, and the honest one that grows burn and collections forward to the month cash actually hits zero — or shows you're default alive. Then it prices the levers: trim burn, collect faster, and watch the runway move.

Runway = cash on hand ÷ net monthly burn (gross cash out − cash collected). The headline above goes further: it grows burn and collections each month and finds the month cash actually hits zero — or, when collections catch up first, default alive. Everything updates live, and the download rebuilds the projection in Excel.
