How to use cash-runway calculator

Enter available cash and monthly collected receipts and payments in one currency. Include or explicitly exclude tax, debt, and capital spending.

Net monthly burn equals payments minus receipts. Divide opening cash by positive net burn for a simplified number of months.

Use a cash-flow schedule when payments or receipts vary. Timing gaps, seasonality, and uncertain collection can matter more than the average.

What to check before using the result

Constant receipts/payments and excluded cash shocks make this a simplified estimate.

  • Use collected cash rather than invoiced revenue.
  • Include relevant payment categories.
  • Check the lowest period balance in a full forecast.

Questions about this workflow

What if receipts cover payments?

The model has no positive net burn and cannot report a finite runway. Review future cash timing and changes separately.

Is runway a complete cash forecast?

No. Use a period-by-period cash-flow model when timing, debt, tax, or capital purchases are material.
