How we calculate thisAssumptions, workings & vehicle sources
What this estimate assumes
This is a petrol-cost estimate using UK gallons. It excludes insurance, tax, servicing and depreciation. For plug-in hybrids, use the PHEV calculator so electricity and petrol are counted separately.
Model presets are official WLTP combined figures. Real-world economy varies with road type, journey length, speed, driving style, temperature and vehicle load.
Your calculation
- — miles ÷ — UK mpg × 4.54609 = — litres a year.
- — litres × —p ÷ 100 = — a year.
- Monthly cost = annual cost ÷ 12. The 100-mile trip uses the same MPG and petrol price.
