Free HMRC Mileage Calculator (2026-27)
Enter your business miles for the UK tax year (6 April to 5 April). The calculator applies the correct AMAP tier for cars (55p / 25p), or the flat motorcycle (24p) or bicycle (20p) rate.
Your deduction
£6,000
- First 10,000 miles at 55p/mile
- £5,500
- 2,000 miles over 10,000 at 25p/mile
- £500
The 25p rate applies per employment, and the 10,000-mile counter resets each tax year (6 April to 5 April).
Deduction only. Parking and tolls are claimed separately, on top of the per-mile rate. Your actual tax saving depends on your personal rate and is not estimated here.
How the AMAP calculation works
Cars: first 10,000 miles × £0.55, miles after × £0.25.
Motorcycles: all miles × £0.24.
Bicycles: all miles × £0.20.
Add parking and tolls separately; those are deductible on top of AMAP.
What this calculator does not include
VAT reclaim. If you are VAT-registered, you can reclaim a portion of the VAT included in the fuel component of AMAP. The reclaim is calculated against the HMRC advisory fuel rate, not AMAP itself. See the VAT-on-mileage page for the calculation.
Company-car drivers. Company-car mileage uses HMRC advisory fuel rates (AFRs), not AMAP. This calculator handles the personal-vehicle AMAP method only.
FAQ
Does the 10,000-mile tier apply across two cars?
Yes. The boundary is per employee, per tax year - not per vehicle. If you drive two personal vehicles for work in the same tax year, the 10,000-mile tier-1 allowance applies once across both.
What if my tax-year mileage straddles two AMAP years?
The first-tier AMAP rate rose from 45p to 55p on 6 April 2026, which is a UK tax-year boundary, so a single tax year does not straddle the change. The trip's date governs which rate applies: trips on or after 6 April 2026 use 55p for the first 10,000 miles, earlier trips use 45p.
