Mileage allowance calculator
I keep the miles in a log, because the flat rate only works if the miles are real. This page multiplies the miles you type. It does not invent a journey.
This is HMRC's simplified expenses mileage, which uses the approved mileage allowance rates. For 6 April 2026 to 5 April 2027, cars and goods vehicles are 55p a mile for the first 10,000 miles, then 25p. Motorcycles are 24p a mile. Before 6 April 2026 the car and van rate was 45p, then 25p. Checked October 2026. I read the pages on 18 October 2026. This is an estimate, not tax advice. The figures stay in the browser.
The choice between this flat rate and the real cost of the van is in the van expenses guide. The wider list of what a trade can deduct is in the allowable expenses guide.

The figures it uses
Checked October 2026. All of these were read from GOV.UK on 18 October 2026. If a page has moved on since then, the page wins.
Cars and vans
For the 2026 to 2027 tax year, 55p a mile for the first 10,000 miles, then 25p. Before 6 April 2026, 45p then 25p. HMRC's own example at the new rate: 11,000 business miles is 10,000 times 55p (£5,500) plus 1,000 times 25p (£250), so £5,750. Simplified expenses: vehicles (opens in a new tab).
Motorcycles
24p a mile, before and after 10,000 miles, and the same 24p before 6 April 2026. The 10,000 mile drop applies to cars and goods vehicles, not to motorcycles.
Approved mileage rates
The travel mileage and fuel rates (opens in a new tab) page, updated 21 May 2026, lists the same 2026 to 2027 pence for cars and vans, and 24p for motor cycles. That page is the approved mileage allowance. It also lists 5p per passenger per business mile for carrying fellow employees. This calculator does not add that 5p.
Simplified expenses can be used by sole traders and by partnerships with no companies as partners. A limited company cannot use them. The simplified expenses overview (opens in a new tab) says so. You cannot use the flat rate for a vehicle you have already claimed capital allowances for, or already put through as an expense. Once you use it for a vehicle, you keep using it while that vehicle is in the business. Do not reprice a 2025 to 2026 log at 55p.

Common questions
Which mileage rates does this use?
For 6 April 2026 to 5 April 2027, cars and goods vehicles are 55p a mile for the first 10,000 miles, then 25p. Motorcycles are 24p. Before 6 April 2026, cars and goods vehicles were 45p then 25p, and motorcycles were 24p. Checked October 2026, from HMRC's simplified expenses vehicles page, read on 18 October 2026. The approved mileage rates page, updated 21 May 2026, shows the same 2026 to 2027 pence.
Can a limited company use simplified expenses?
No. Simplified expenses are for sole traders and for partnerships that have no companies as partners. A limited company cannot use them. Approved mileage allowance payments are a different scheme, for employees. For 2026 to 2027 the pence on that rates page match. This calculator does the multiplication. It does not decide which scheme you are in.
Can I claim this and the real van costs?
Not for the same vehicle. Once you use the flat rate for a vehicle, you keep using it while that vehicle is in the business. You also cannot use it if you have already claimed capital allowances for that vehicle, or already put it through as an expense. The van guide on this site sets the choice out.
Does the 10,000 mile split apply to a motorcycle?
The rate does not change. Motorcycles are 24p a mile both before and after 10,000 miles, in the 2026 to 2027 table and in the earlier table. The split on this page is for cars and goods vehicles.
Are parking and passenger payments included?
No. HMRC's vehicles page says you can claim parking, and other travel such as a train fare, on top of the flat rate. The approved mileage rates page also lists 5p per passenger per business mile for carrying fellow employees in a car or van. That 5p is not added here.
