Fuel Cost Calculator — United Kingdom
Calculate trip, daily, weekly, monthly and yearly fuel costs in L/100 km, MPG or km/L. For United Kingdom drivers this uses real local figures where we have them — a MOT costs about £54.85 per test and annual vehicle excise duty (VED) is around £190 per year. Prices default to GBP and UK miles per gallon.

Why cost of ownership matters
The purchase price is only the beginning. Fuel or electricity, insurance, vehicle excise duty (VED), the MOT, servicing, tyres, repairs and depreciation together usually cost more than the car itself over a few years. Use this tool to see the full picture before you buy.
How to use this calculator
Enter realistic figures for your situation — what you actually pay for insurance, what you expect to drive in a year — and the tool breaks the total down into monthly, weekly, yearly and per-distance costs. Adjust any figure and the results update instantly.
Frequently asked questions
Which units does the fuel cost calculator use?
You can enter consumption as L/100 km, MPG or km/L, and prices per litre or per gallon — the figures are converted for you and shown in GBP.
How do I work out my real fuel cost per mile?
Enter your own consumption and the price you actually pay at the pump rather than the manufacturer's figure; the tool then shows the cost per trip, per week, per month and per year.
Can I budget for a trip?
Yes — enter the distance and the tool gives the one-way and return fuel cost, which is also what the Trip Cost Calculator uses for a whole journey.
Does it include vehicle excise duty (VED) or the MOT?
No — this tool covers fuel or energy only. Those costs are part of the Car Cost Calculator, which totals everything for the UK.
