Mileage Claim Calculator (2026/27)

How this is calculated

When you use your own vehicle for business travel, HMRC lets you claim a tax-free Approved Mileage Allowance Payment (AMAP) — a flat amount per mile that covers fuel, wear and running costs. This calculator multiplies your business miles by the approved rate for your vehicle.

For a car or van the rate is tiered: the first 10,000 business miles at 55p per mile, then 25p per mile above that. A motorcycle is a flat 24p per mile and a bicycle is a flat 20p per mile, with no tier step. For example, 12,000 car miles = 10,000 × 55p + 2,000 × 25p = £6,000.00.

Assumptions & notes

• The 10,000-mile threshold is per tax year and per person, across all cars/vans; it resets each 6 April.
• If your employer pays you less than the AMAP rate, you can claim tax relief on the shortfall (Mileage Allowance Relief). If they pay more, the excess is taxable.
• The self-employed can use these simplified mileage rates instead of claiming actual running costs — but not once you've claimed capital allowances on the vehicle.
• Passenger payments (5p per mile per passenger) and separate rules for company cars are not included here.

Rates used (2026/27)

• Car or van: 55p for the first 10,000 miles, then 25p.
• Motorcycle: 24p per mile (all miles).
• Bicycle: 20p per mile (all miles).
