Frequently Asked Questions
This tool derives your net burn from monthly expenses and revenue, then computes runway from your cash balance in one step. Startup Runway Calculator instead takes total cash and monthly burn directly as inputs — use whichever figures you already have.
The tool reports that you're cash-flow positive with no burn — runway isn't a meaningful constraint from operations alone in that case.
No — it assumes your monthly expenses and revenue figures are representative of an ongoing, steady month. Large one-off costs will make actual burn higher than this estimate in the month they occur.
Use net revenue actually collected (cash basis), not invoiced/accrued revenue — burn rate is about actual cash movement, not accounting revenue.
