What is Startup Runway Calculator?
The Startup Runway Calculator is a free online tool that helps founders and finance teams work out how long their current funding will last. You enter your cash on hand, monthly expenses (burn rate), and any recurring revenue, and the calculator computes your net burn, runway in months, weeks, and days, plus the projected date you will run out of money. It also shows a color-coded health status so you know instantly whether you are in a critical, caution, or healthy zone - the essential metric for any startup planning its next fundraise.
