Which calculator should I use?

Start with the question you actually have. This table sends you to the narrowest tool first, so you do not need to work through unrelated inputs.

If your question is…Start here
You want a broad two-car cost comparisonReal Running Cost Comparator
You are deciding whether to keep or changeKeep vs Change Car
You are comparing petrol and EV energy costPetrol vs EV
You want annual fuel spendAnnual Fuel Cost
You want pence per mileFuel Cost Per Mile
You want to compare annual fuel savingsFuel Savings

Compare the costs that actually differ

A useful ownership comparison avoids double-counting costs that are the same in both options. Enter your own fuel, electricity, mileage, insurance, maintenance and depreciation assumptions where the tool asks for them.

How these calculators are produced

MotoringCalcs separates defined conversions from scenario estimates. Exact unit relationships use direct arithmetic. Where a result depends on assumptions — such as drivetrain difference, real-world efficiency or future cost — the assumption is visible and editable rather than silently fixed.

Inputs remain in your browser and the tools do not require an account. Where manufacturer specifications, measured vehicle data or your actual tariff are available, use those values in preference to generic example inputs.

These tools are for calculation, comparison and planning. They do not replace manufacturer guidance, inspection or professional engineering advice where safety or fitment is involved.
