If you're wondering how to calculate mileage for car insurance, this is the place to start. A good estimate can help you avoid overpaying or underestimating.

Does my annual mileage affect my car insurance?

Your annual mileage is one of the factors used to calculate your car insurance.

If you're someone who makes a lot of journeys in their car, your car insurance might be more expensive. This is because the more you drive, the more likely you are to have an accident or make a claim.

Our car insurance calculator can help you work out how much you might pay.

How to estimate miles if your routine changes

Not everyone has a set schedule. If your weekly mileage varies, try averaging it out over a few weeks. Include things like:

  • Work from home days
  • School holidays
  • Seasonal travel

And don’t forget occasional long journeys , even a few big trips a year can make a noticeable difference to your annual total.

Fuel saving tips

While this tool focuses on mileage, it’s always helpful to save fuel where you can. Here are a few quick tips:

  • Plan ahead: Apps can help you avoid traffic and find shorter routes. Less time driving, will mean fewer miles
  • Drive as smooth as you can: Braking and accelerating harshly uses more fuel.
  • Lighten the load: Remove roof racks and clear out your boot if you don’t need the extra weight.
  • Check your tyres: Low tyre pressure increases resistance, fuel use and can even cause your car to pull to one side.
  • Avoid idling: Restarting your engine usually uses less fuel than leaving it running, plus you could get fined if found guilty of engine idling.
  • Regular servicing: A well-maintained car runs more efficiently.

What happens if I drive more miles than I estimated?

If you drive more miles than estimated, you may need to update your car insurance policy or lease agreement. You may also need to pay an excess mileage charge if you go above your lease agreement's mileage limit.

You may need to tell your insurer about the change. They may charge you an adjustment fee or increase the cost of your premium.

It's always worth telling your insurer if your mileage changes. If you end up with a lower annual mileage than you thought, it's not usually a problem. If your estimated mileage isn't accurate your insurance may be invalidated.

Do both petrol and diesel cars have the same range as electric cars?

No, petrol and diesel cars generally have a greater range than electric cars. But the range of any car depends on the terrain, the speed, and how it's driven.

Petrol and diesel cars can have a range of over 500 miles. Electric cars tend to have a range of around 300 miles on a full charge.

The range of electric vehicles can vary depending on the model, battery size, and the driving conditions.

How many miles do most people drive in a year?

It varies, but in the UK the average annual mileage is around 7,000 to 8,300 miles. Commuters and regular drivers may do more.
