What this tool does
Runway is the number that sets every other deadline in a young business: it decides when a funding round has to close, when hiring has to pause and when a product has to start earning. When revenue exceeds costs there is no runway to run out of, and the tool says so.
Formula
range = cash flow ÷ (expense − income)
