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 are pricing a single driveJourney Fuel Cost
You are planning a longer return tripRoad Trip Cost
You are budgeting a regular commuteCommute Cost
You are splitting fuel between passengersFuel Cost Split
You are considering a detour for cheaper fuelCheaper Fuel Detour
You need speed-to-pace conversionMPH to Minutes per Mile

Use a realistic MPG rather than the best-case figure

Journey estimates become much more useful when the MPG input reflects your actual driving. Traffic, weather, diversions, parking and tolls can sit outside a fuel-only calculation, so keep the scope visible.

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.
