Formula and cost boundary

Stressed closing cash = opening cash + receipts × (1 − delayed share) − base payments − additional payment

Delayed receipts are moved beyond the period, not written off as lost revenue. Add them to the appropriate future period in a rolling schedule. The extra payment must not already be inside base payments. This single-period stress does not identify the worst day or week. Reserve is a comparison threshold, not another expense; negative balances are displayed as funding gaps.

Worked example: Delayed invoices and one-off payment

The following inputs are hypothetical values for checking the calculation. They are not recommended prices, wages, margins or platform charges. Keep the units and period shown in each label when replacing them with your own records.

Using the result

Save the input set alongside the source date of each quote or cost record. Review the cost boundary before comparing this result with another report: a contribution measure may exclude overhead, and a cash measure follows payment dates. Display rounding does not change the underlying assumptions. Recalculate when an input changes; the tool does not predict future sales or collections.

Are any rates supplied automatically?

No. Numeric fields are your inputs. Example values demonstrate arithmetic only. Check your contracts and records for the amounts that apply to your business.

Why might a result be unavailable or negative?

A missing denominator or inconsistent inputs can make the calculation undefined. Those combinations are rejected or labeled explicitly. A valid negative result remains visible because it may identify a loss or cash shortfall.
