Runway & Burn Calculator

The Runway & Burn Calculator turns your cash balance, monthly revenue, and monthly expenses into a net burn rate and a runway-in-months figure — with a plain-language read on how urgently you need to raise or cut costs.

What counts as "burn"?

Net burn is monthly expenses minus monthly revenue. If revenue exceeds expenses, you are cash-flow positive ("default alive").

How much runway is considered healthy?

18+ months is comfortable; 12–18 is workable if you start fundraising early; under 6 months is critical — most stalled companies got there by starting their raise too late, not by running out of cash unexpectedly.

Should I count pending investment as cash?

No — only count cash actually in the bank today for an honest number.
