METHODOLOGY

How the analysis works.

This simplified calculator applies the same expected weekly inflow and outflow for thirteen weeks and adds the resulting cumulative net cash movement to starting cash.

LIMITATIONS

What this does not replace.

A real 13-week cash-flow forecast should model each week separately, including customer receipts, supplier payments, payroll, taxes, debt service and one-off items. Use FinanceGPT for a complete forecast Build.
