Runway: How Many Months Until the Money Runs Out
Runway turns a bank balance into a deadline. Knowing it in months makes fundraising and hiring decisions concrete instead of vague.
What is the Runway Calculator?
Enter cash available and monthly net burn, and the tool gives runway in months. This is an estimate that assumes burn stays flat; a change in spending or revenue changes the answer, so re-run it whenever either moves.
How to use it
- Enter cash available.
- Enter monthly net burn.
- Click Calculate Runway to see months remaining.
Worked example
With 60000 cash and 6000 monthly net burn, runway is 10 months.
How much runway should a startup aim for?
Many founders aim for 12 to 18 months, which leaves time to raise funds or reach revenue before cash gets tight.
Frequently asked questions
What if burn changes next month?
Re-run the calculation. Runway is a snapshot, and a new burn rate gives a new runway.
Does runway include future funding?
No. It only counts cash you already have, so planned funding should be treated separately.
