Startup Runway Calculator
Runway is how long the business survives at its current rate. Enter your cash on hand, what goes out each month and what comes in, and you get the number of months before you run out.

How to read this
Net burn is monthly spend minus monthly income. Runway is cash divided by net burn. If income exceeds spend you are default alive and runway stops being the constraint.
Runway is a planning instrument, not a scoreboard. Its value is that it converts a decision — a hire, a tool, an ad budget — into weeks of life, which is a much harder thing to hand-wave than a monthly cost.
The usual advice is to start raising or cutting well before the number gets small, because both take longer than expected. Watching runway monthly, rather than discovering it quarterly, is most of the benefit.
Common questions
- What should count as cash on hand?
- Money you can actually spend — bank balances, and credit you have genuinely committed. Invoices you hope to collect are not cash until they land.
- Should I include my own pay in burn?
- If you are taking it, yes. If you are not, note that your real runway is shorter than the number shown once you start.
- What is a healthy amount of runway?
- There is no universal figure, but the common guidance is to begin acting — raising, cutting, or growing revenue — while you still have several months left, since every one of those takes months to work.
