• Runway (weeks)
  • Runway (months)

Net burn is what your cash falls by in an average month. If the figure is zero or negative, your cash is steady or growing and runway is effectively open-ended. This is a planning estimate — real months vary, and a single late invoice can change the picture.

Runway, then the right tool

A short runway is a signal to act early — chase what you are owed, trim the burn, and only then consider finance for a specific, time-boxed gap. Borrowing to cover an ongoing loss rarely ends well. Read when not to borrow, and if a genuine short gap remains, size it with the working-capital gap calculator.
