Runway calculator
Enter your cash position. We’ll estimate months of runway and when you might hit zero — privately, in this browser.
Your numbers
Cash in bank you can use for operations
Average net cash you spend each month. Zero = break-even (unlimited runway).
We use expenses − income as your net burn. If income ≥ expenses, runway is unlimited.
