Frequently asked
What does 'total cost of ownership' actually include?
Finance payments, fuel or electricity, insurance, road tax (VED), servicing, tyres and MOT. We don't include depreciation as a cash line because on PCP the balloon captures it, and on HP you keep the car — but expect a used car to lose 10–20% per year in the early years.
Are EVs really cheaper to run?
In fuel and tax, generally yes — home charging at ~7–15p per kWh works out to 2–4p per mile versus 12–18p for a petrol equivalent. Insurance and finance can be higher, and from April 2025 EVs pay standard VED. The tool lets you flip between EV and petrol/diesel to see your numbers.
Where do MPG and mi/kWh figures come from?
Use your car's WLTP combined figure, or your own average from the trip computer. For an EV, mi/kWh (efficiency) is the equivalent of MPG. 3.5–4.5 mi/kWh is typical for a mid-size EV; 40–55 mpg is typical for a modern petrol.
Why is pence-per-mile useful?
It's the great equaliser — it lets you compare a cheap car with high running costs against an expensive car that's cheap to run. Under 30p/mile is efficient; over 60p/mile is expensive and usually means either a big car or big finance.
