What runway tells you

Cash runway estimates how many months a business can keep operating before cash is exhausted. It is most useful when reviewed regularly with updated revenue, payroll, rent, debt, and tax assumptions.

Runway versus safety margin

Runway focuses on net burn. Safety months compare cash with total monthly expenses, which gives a more conservative liquidity buffer.
