Cost Per Mile Calculator UK: How to Calculate Your Real Driving Costs
If you want to understand what your car really costs, you need to calculate cost per mile. This is one of the simplest ways to see whether your vehicle is affordable and whether a different car might save you money.
What Goes Into Cost Per Mile?
A realistic cost per mile calculation should include more than fuel. You should include:
- fuel or electricity
- insurance
- servicing
- MOT
- repairs
- tyres
- road tax
- depreciation
Simple Cost Per Mile Formula
Total annual vehicle costs ÷ total annual miles = cost per mile
Example
If your annual costs are £5,200 and you drive 8,000 miles:
£5,200 ÷ 8,000 = £0.65 per mile
That means every mile costs 65p.
Why It Matters
Knowing your cost per mile helps with comparing different cars, budgeting accurately, and checking if business mileage rates are fair.
It is especially useful alongside our guide to the true cost of car ownership and our article on HMRC mileage rates.
