Frequently Asked Questions
Runway (months) = Total Cash divided by Monthly Burn, rounded down to the nearest whole month. The tool also shows the equivalent in years.
No - it's a straight-line calculation based on your current cash balance and current monthly burn rate only. It doesn't model future revenue ramp, cost changes, or additional funding rounds.
Whatever figure you enter as your monthly burn - typically your net cash outflow (expenses minus any revenue) for a typical month. Use the Burn Rate Calculator first if you need to derive that number from your bank balances.
Most investors and operators consider 12-18 months a comfortable minimum before you need to be actively fundraising again, though this varies by stage and market conditions - this tool only reports the raw number, not investment advice.
