Gross burn − revenue
Trimming burn 20% buys about 5.4 more months — often the difference between raising on your terms and raising on theirs. Efficiency extends runway faster than new revenue at this stage.
Runway assumes flat revenue. Growing revenue extends it further, but efficiency gains are within your control today — new revenue isn't.
About this calculator
Model current runway from cash, burn and revenue, then see how reducing burn or improving efficiency extends the months you have before you need to raise again.
