Car Running Cost Calculator

Estimate annual car running costs from fuel, insurance, VED, maintenance and other recurring costs. Finance and depreciation stay separate.

Estimate ownership costs

Enter annual costs to estimate running cost; finance and depreciation are not included.

What your result means

This annual model combines entered fuel spending with insurance, VED, servicing/maintenance and other recurring costs. It deliberately excludes depreciation and finance so those decisions remain visible rather than silently assumed.

Worked example

Using 12,000 miles, 45 UK MPG, 142p/litre and £1,300 of annual non-fuel costs:

Fuel
£1,721.45
Total
£3,021.45

Change each cost to match the car and period you are considering.

Formula

Total=Fuel+Insurance+VED+Maintenance+Other\text{Total}=\text{Fuel}+\text{Insurance}+\text{VED}+\text{Maintenance}+\text{Other}

Annual mileage sensitivity at example costs

Annual milesTotal running cost
8,000£2,447.64
12,000£3,021.45
16,000£3,595.27
20,000£4,169.09

Assumptions and limitations

  • Annual figures are used for consistency; the result shows a monthly average as well.
  • Depreciation, finance payments, parking, tolls and unexpected repairs are excluded unless included in other costs.

Helpful questions

Does this include depreciation?

No. Use the Car Depreciation Calculator to assess value loss separately.

Does this include finance?

No. Finance is separate from running cost; use the Car Loan Calculator or finance comparison tools.
