HMRC approved rates from 6 April 2026: cars and vans 55p a mile for the first 10,000 business miles and 25p after, motorcycles 24p, bicycles 20p, passengers 5p. Commuting to a permanent workplace does not count as business travel.

Using your own car for work? This mileage allowance calculator works out the tax free amount HMRC allows for your business miles in 2026/27, including passenger payments. The rates come from HMRC's approved mileage allowance payment rules, and the results show whether you can claim tax relief because your employer pays less, or owe tax because they pay more.

What Is the HMRC Mileage Allowance?

Approved Mileage Allowance Payments (AMAPs) are the most an employer can pay you per business mile without it counting as taxable income. From 6 April 2026 the car and van rate rose from 45p to 55p a mile for the first 10,000 business miles in a tax year, with 25p a mile after that. Motorcycles are 24p and bicycles 20p.

For a car, the formula is (first 10,000 miles × 55p) + (remaining miles × 25p). So 12,000 miles gives £5,500 + £500 = £6,000. If your employer pays only 45p, you receive £5,400 and can claim Mileage Allowance Relief on the £600 gap. That saves £120 at 20% tax.

How to Use the Mileage Allowance Calculator

Step 1: Choose Your Vehicle

Select car or van, motorcycle or bicycle. To compare the rate with your real running costs, the MPG calculator works out your actual fuel economy and cost per mile. Cars and vans share the same approved rate, and the type of fuel makes no difference, including electric.

Step 1: choose your vehicle type

Step 2: Enter Your Miles and Passengers

Add your total business miles for the tax year. For a car or van, enter how many colleagues travel with you on business trips. The calculator assumes they come on every business mile.

Step 2: enter business miles and passengers

Step 3: Enter What Your Employer Pays

Type the pence per mile your employer pays you. If you get no mileage payments, enter 0 and you can claim relief on the full approved amount.

Step 3: enter what your employer pays per mile

Step 4: Read Your Results

You will see the approved amount, what your employer paid, any relief to claim or taxable excess, and the tax saving at 20% and 40%. Sole traders can use the same rates as a simplified expense, and the self employed tax calculator shows how business expenses like these reduce your Income Tax and National Insurance.
