Cash Forecast Error Reconciliation Table
Reconcile receipt and payment errors with closing cash across five scenarios, keeping each sign and percentage denominator explicit.
This reference holds opening cash at $5,000, forecast receipts at $20,000 and forecast payments at $15,000. Forecast closing cash is therefore $10,000. Each row changes actual receipts, payments or both. Differences are actual minus forecast. A positive payment difference is an extra outflow and consequently lowers closing cash; its sign must be reversed in the closing-balance bridge.
Closing cash error = receipt error − payment error; actual closing = $10,000 + closing cash error
| Actual receipts | Actual payments | Receipt error | Payment error | Closing cash error | Actual closing cash |
|---|---|---|---|---|---|
| $20,000 | $15,000 | $0 | $0 | $0 | $10,000 |
| $18,000 | $15,000 | −$2,000 | $0 | −$2,000 | $8,000 |
| $20,000 | $16,000 | $0 | $1,000 | −$1,000 | $9,000 |
| $18,000 | $16,000 | −$2,000 | $1,000 | −$3,000 | $7,000 |
| $22,000 | $14,000 | $2,000 | −$1,000 | $3,000 | $13,000 |
Interpret the result
The last row produces more closing cash than forecast, but the favorable sign does not identify the cause. A supplier payment that was delayed can improve cash while leaving an obligation due next week. Likewise, an early customer receipt can reverse in the next period. Explain timing shifts separately from permanent volume or price changes before updating assumptions.
Check before applying the example
Reconcile opening balances first. If actual opening cash differs from the forecast opening, its error belongs in the bridge as another component. Percentage errors use their own forecast denominator: a $2,000 receipt miss is 10% of $20,000 receipts, while a $1,000 payment excess is approximately 6.67% of $15,000 payments. Ratios with a zero forecast denominator remain undefined.
