About the UK Mileage Calculator
Use this UK mileage calculator to estimate your business mileage claim using HMRC approved rates for the 2026/27 tax year.
Select your vehicle type and enter your business miles to see the mileage rate used and your total allowable claim. For cars and vans, the calculator applies 45p per mile for the first 10,000 business miles and 25p per mile above that threshold.
Motorcycle and bicycle claims use flat rates of 24p and 20p per mile respectively. These simplified rates are commonly used by self-employed taxpayers instead of claiming actual vehicle running costs.
This calculator provides an estimate only. Always check your eligibility and record keeping requirements before submitting a claim to HMRC.
