About UK Mileage Calculator

UK Mileage Calculator is a free UK business-mileage tool for people who want a quick calculation without creating an account.

What it covers

The calculator supports HMRC mileage rates for 2026/27 and 2025/26, with separate modes for eligible self-employed simplified vehicle expenses and employee Approved Mileage Allowance Payments.

Why it exists

The headline car and van rate changed from 45p to 55p for the first 10,000 business miles from 6 April 2026. This site is designed to make the new rate, the 10,000-mile threshold and the difference between self-employed and employee treatment easier to understand.
