UK Mileage & Fuel Expenses Calculator
HMRC lets employees and self-employed people claim business mileage at fixed rates. For 2026/27 cars and vans attract 55p per mile for the first 10,000 business miles and 25p per mile above that, motorcycles 24p and bicycles 20p per mile. You can also claim 5p per mile for carrying fellow employees as passengers.
Enter your business miles to see your claim.
How the calculation works
We believe numbers should be transparent. Here is the formula behind this calculator.
Worked example
Worked example: 15,000 car miles in 2026/27
Examples at common levels
See how the numbers change at typical input levels, using the updated for tax year 2026/27 rates.
| Scenario | Mileage claim total | At 55% per mile | Passenger payments | First 8,000 miles | 0 miles above 10,000 |
|---|---|---|---|---|---|
| 8,000 car miles All at 55p | £4,400.00 | £4,400.00 | £0.00 | £4,400.00 | £0.00 |
| 15,000 car miles 10,000 at 55p, 5,000 at 25p | £6,750.00 | £6,750.00 | £0.00 | £5,500.00 | £1,250.00 |
| 3,000 motorcycle miles 24p per mile | £720.00 | £720.00 | £0.00 | £720.00 | £0.00 |
| 2,000 bicycle miles 20p per mile | £400.00 | £400.00 | £0.00 | £400.00 | £0.00 |
| 6,000 car miles + 2,000 passenger 55p plus 5p per passenger mile | £3,400.00 | £3,300.00 | £100.00 | £3,300.00 | £0.00 |
Important assumptions
- Uses the official Approved Mileage Allowance Payments rates for the selected tax year.
- The 55p first-rate applies to cars and vans from 6 April 2026 (45p before).
- Rates are per business mile driven in your own vehicle — commuting between home and a fixed workplace is not business mileage.
- Passenger payments of 5p per mile apply to cars and vans only, for fellow employees.
Rates & official sources
Every calculation is based on the official rates and rules published by GOV.UK and HMRC.
Frequently asked questions
How much can I claim for mileage in 2026/27?
Cars and vans: 55p per mile for the first 10,000 business miles and 25p per mile above that. Motorcycles: 24p. Bicycles: 20p. You can also claim 5p per passenger mile for carrying fellow employees.
Is mileage claimable by employees?
Yes. If your employer does not reimburse business mileage, you can claim tax relief at the HMRC rates through your Self Assessment return or by asking HMRC to adjust your tax code.
What is the difference between commuting and business travel?
Travel between home and a permanent workplace is ordinary commuting and cannot be claimed. Travel between different workplaces, or to visit clients, is business mileage and can be claimed.
Can I claim mileage if I am self-employed?
Yes. Sole traders can either deduct actual vehicle costs or use the simplified mileage rates shown here, which cover fuel, insurance, tax, servicing and depreciation. You cannot claim both for the same vehicle.
