The cost most people never add up
A commute feels free because you pay for it a tank at a time. Add it up across the year and it is usually one of the biggest motoring costs you have. This calculator uses your actual round trip, the days you drive in, your car's mpg and the live price near you, and shows the yearly figure alongside the weekly and monthly ones. Change the weeks box to allow for holidays and days working from home.
The useful part is the second line. By reading the real prices around your postcode district, it shows what you would pay by always choosing the cheapest forecourt versus the dearest, and that gap, repeated every week of the year, is often a surprising amount of money for no effort beyond a slightly different turn on the way home.
Bringing it down
Three things cut a commute bill. Pay less per litre by picking the right forecourt, which this page shows you. Use less fuel by driving smoothly and keeping tyres pumped up, covered in our guide on how to use less fuel. And drive in fewer days, since every day you work from home takes a whole round trip off the bill. Set a free price alert to fill up at the low point each week.
Common questions
How much does commuting by car cost?
It depends on distance, mpg and price. As a guide, a 24 mile round trip five days a week in a 45 mpg car at today's typical price costs roughly 20 pounds a week and over 900 pounds a year in fuel alone. Enter your own figures above for an exact number.
How can I reduce my commute fuel cost?
Fill up at the cheapest forecourt near you rather than the most convenient, drive smoothly and keep your tyres at the right pressure, and work from home where you can, since each day at home removes a full round trip from the bill.
Does this include wear, tax and insurance?
No, it covers fuel only, which is the part that changes with where you buy. Wear, tax, insurance and depreciation come on top and are largely the same whichever forecourt you use.
