Mileage Calculator (UK HMRC)
Work out a mileage claim using current HMRC approved rates, or switch to your own company rate if you pay a different amount per mile.
Calculator
HMRC rates are selected by default. Enter one-way business miles, tick return journey if needed, and choose HMRC or your company rate.

Results
HMRC figures use the tax year and rates from the shared AMAPs configuration shown in the results. Company rates are whatever your business sets. This is a guide only, not tax advice.
How This Calculator Works
What it does
This calculator estimates a business mileage claim using either the current HMRC Approved Mileage Allowance Payments (AMAPs) or a custom company mileage rate. It also supports return journeys by automatically doubling the entered mileage.
How the calculation works
When HMRC rates are selected, cars and vans use the higher mileage rate up to the annual threshold, with any additional business miles calculated using the lower rate. Motorcycles and bicycles use their standard HMRC rates for all claimable miles.
If the Return Journey option is selected, the entered mileage is doubled before the calculation is performed.
When Company Rate is selected, the claim is calculated using the custom pence-per-mile rate entered by the user.
Formula
If Return Journey is selected
- Total Claimable Miles = Business Miles × 2
HMRC
- Mileage Claim = (Miles at Higher Rate × Higher Rate) + (Miles at Lower Rate × Lower Rate)
Company Rate
- Mileage Claim = Total Claimable Miles × Company Rate
Why it matters
Accurately calculating business mileage helps ensure employees and self-employed tradespeople are reimbursed correctly while remaining consistent with HMRC guidance or company policy. The return journey option reflects how many tradespeople calculate mileage for travelling to and from customer sites.

Frequently asked questions
Straight answers about this calculator and how UK trades use the figures day to day.
What are the current HMRC car and van rates?
Cars and vans use a higher rate up to the annual AMAPs threshold, then a lower rate. The tax year and exact rates applied are shown in the calculator results, which read from the shared HMRC configuration.
Can I use my company mileage rate instead?
Yes. Choose Company rate and enter the pence per mile your business pays. That overrides the HMRC defaults for the claim total.
How does return journey work?
Enter the one-way business miles, then tick Return journey. The calculator doubles the miles before applying HMRC or company rates.
Why enter miles already claimed?
For cars and vans, HMRC uses a higher rate up to an annual threshold. Entering miles already claimed this tax year ensures only the remaining higher-rate allowance is used first.
Do electric cars use the same HMRC rates?
Yes. Cars and vans (including electric and hybrid) use the same AMAPs band structure.
What about motorcycles and bicycles?
They use their standard HMRC rates for all claimable miles, without the car and van threshold split.
Where do the HMRC rates come from?
From HMRC / GOV.UK travel mileage and fuel rates publications. Update the shared rates configuration when GOV.UK publishes new figures.
