| Example | Key Figures |
|---|---|
| Example 1 | Mileage £0.45 mi, per‑diem £25/day |
| Example 2 | Mileage £0.60 mi, per‑diem £30/day |
| Total | Adjusted claim ≈ £1,200 |
Because most NHS staff claim mileage at the HMRC‑approved rate of 45 p per mile for the first 10,000 miles, the calculator automatically applies that figure.
You've entered the total kilometres you travelled, and the tool converts them to miles using the statutory 1.609 km‑per‑mile factor.
For mileage between 10,001 and 20,000, the calculator switches to the reduced 25 p rate, then to 20 p beyond 20,000.
It also adds the standard £0.20 per kilometre for public‑transport receipts and the £4.00 daily subsistence allowance for overnight shifts.
The output summarises gross claim, tax‑free portion, and net payable, enabling you to verify compliance instantly today.

How often do you overlook the distinction between mileage rates for personal versus business journeys, inflating or invalidating claims?
You're often mixing up per‑mile allowances with actual fuel receipts, leading HMRC to reject submissions.
You may also double‑count travel by recording the same trip under both mileage and public‑transport sections.
You frequently forget to exclude commuting, which is non‑reimbursable, thereby overstating expenses.
You neglect to retain original invoices for meals, accommodation, or equipment, so auditors can't verify amounts.
You apply old rates instead of HMRC figures, causing errors.
You ignore the requirement to prorate shared‑use assets, inflating claim totals.

For NHS staff, you must respect the 4‑hour maximum per‑diem for overnight stays and the capped meal allowance.
The system should flag any entry exceeding these thresholds, ensuring that submitted claims remain audit‑ready and tax‑efficient throughout the upcoming fiscal year period.
Having defined the statutory mileage rates and per‑diem caps, the calculator now interprets them using the United Kingdom’s standard units—miles for distance, pounds sterling for monetary values, and calendar days for time periods.
You input each journey’s start and end points; the system converts kilometres to miles, applies the current HMRC rate, and multiplies by the recorded distance.
You also record accommodation nights, meals, and incidental expenses; the calculator aggregates daily allowances in pounds, respects the per‑diem ceiling, and flags any excess.
