Formula
Runway (months) = Available cash ÷ Net monthly burn
Runway is the number of months a company can keep operating with its current cash at its current burn rate before running out of liquidity if nothing changes.
How it is calculated
Runway (months) = Available cash ÷ Net monthly burn. Net burn = payments − receipts in the month (if negative, the company generates cash and runway is infinite).
Example with numbers
Cash 600,000, monthly receipts 150,000, payments 200,000: net burn 50,000; runway = 12 months. With an undrawn credit line of 100,000, real availability is 700,000 and runway 14 months.
How Fibady does it
