How it calculates

All resources

  • Gross burn is the three-month average of cash out; net burn subtracts cash in from operations.
  • Runway is cash divided by net burn; on the plan, it ends in the first month cash goes below zero.
  • The latest month to start the raise is the last full month of cash, on the plan if you add one, less your lead time. A plan that holds 24 months or more shows Beyond 24 months.
  • The default alive check holds expenses flat and grows revenue at the recent rate, after Paul Graham's Default Alive or Default Dead? (2015).
