How the cash runway calculator works
Each month cash changes by revenue − expenses. Revenue grows at your monthly growth rate. Runway ends when cash reaches zero.
Example
Using the default inputs (Cash on hand: $180,000; Monthly expenses: $32,000; Monthly revenue: $14,000; Monthly revenue growth: 4%), the calculator returns runway of 13 months. Change any field above to see your own result and charts update instantly.
