Check a hire charge when extra days hit the weekly cap
A hire quote may charge at least one week, then cap extra-day fees at the next weekly price. Use this check only when that exact model is agreed for one item. It shows where the partial-week cap changes the amount before you prepare or query an invoice.

Worked example: the fifth extra day reaches the cap
Fictional rates: A$400 per seven days and A$90 per additional day. For 12 billable days: one complete week is A$400; five extra days would be A$450, capped at A$400. The calculated hire-only total is A$800. A proposed A$850 is A$50 higher under this model. These are invented demonstration amounts, not a supplier quote or a customer bill.
| Billable days | Full blocks / minimum | Extra days | Hire only |
|---|---|---|---|
| 1 | 1 | 0 | A$400.00 |
| 7 | 1 | 0 | A$400.00 |
| 8 | 1 | 1 | A$490.00 |
| 11 | 1 | 4 | A$760.00 |
| 12 | 1 | 5 | A$800.00 |
| 14 | 2 | 0 | A$800.00 |
| 15 | 2 | 1 | A$890.00 |
How the calculation works
For 1–7 confirmed billable days, use one weekly fee. Above seven days, count complete seven-day blocks and price them at the weekly rate. For the remaining 1–6 days, use the smaller of the entered extra-day sum and one weekly fee. Add both parts. The difference is the proposed hire-only amount minus that result. Money is calculated in integer cents, so this check does not round daily totals repeatedly.
Check these boundaries first
- Confirm billable days from the agreement and handover/return records. The form does not infer them from dates, operating hours, weekends or public holidays.
- Do not use it for a five-day hire week, monthly packages, percentage-based extra days, different rate periods, multiple items or an agreement with no weekly cap.
- Use the same GST basis throughout. Delivery, pickup, fuel, damage waiver, deposits, credits and prior invoices are excluded. Do not compare an all-in invoice total against this hire-only result.
- A cheaper arithmetic result does not establish a refund, entitlement or supplier error. Confirm the agreed rules before changing a document.
Turn the checked amount into a clear invoice line
Match the period, equipment and rate card to the job records. Resolve any difference with the other party. If you are the supplier, manually enter only the agreed description and amount in the invoice tool, review GST settings and the customer preview, then export. The checker does not change drafts, import rental records or issue credits.

Questions before use
Is a week always seven billable days?
No. This checker supports that specific agreed model only. Confirm the supplier’s counting rules before entering whole billable days.
Does the result add GST or create an invoice?
No. It compares hire-only amounts on the same tax basis. You decide the correct tax treatment and manually create any customer document separately.
