Frequently asked questions

What does "cash runway" mean for a small business?

Cash runway is the time current cash would last if the net cash shortfall you enter continued at the same rate. In this calculator, runway = cash available now ÷ monthly cash shortfall when outflows exceed inflows. It is a constant-run-rate scenario, not a forecast.

Cash Runway

What if my average monthly revenue already covers my expenses?

Use cash inflows and cash outflows on the same basis. If the entered inflows cover the entered outflows, this constant-run-rate model has no cash-depletion countdown; that does not mean future cash is guaranteed or that timing differences cannot create a shortfall.

Cash Runway

Should I use recent months or a longer average?

Use a period that represents the run-rate you want to plan against. A shorter window reacts faster but can be noisy; a longer window smooths one-offs but can lag recent changes. There is no universal lookback period, so compare multiple defensible windows when the business is changing quickly.

Cash Runway

When should I revisit my runway number?

Recalculate when cash available, recurring inflows or recurring outflows change materially, and at whatever reporting cadence is useful for the business. The model is a snapshot of the inputs at the time it is run.
