The short answer

Cash runway is how many months your cash will last.

Burn = fixed costs + loan repayments - monthly gross profit.

If burn is zero or less, the business funds itself.

If not, runway = cash divided by burn.

Decide by runway minus the months your fix needs to land.

It assumes steady sales and costs. Real months vary, and receivables and stock swing cash by large amounts. Run it with a bad month as well as an average one, and build the full 13-week forecast for a precise picture.

FAQs

Questions owners ask us

What is cash runway?

The number of months a business can continue before cash runs out, at its current rate of burn.

What counts as cash?

Bank balances and any limit your bank will actually let you use. Do not count overdue receivables you are unlikely to collect.

What if the result is negative burn?

Then the business covers fixed costs and repayments from gross profit. Test a bad month to see how thin the cushion is.

How often should I recalculate?

Monthly in normal times, weekly when runway is under six months.
