About Save Range

Save Range is a free set of calculators that help electric-car owners keep and extend their real-world range — and help drivers weighing an EV see what it actually costs versus petrol, diesel or LPG.

Every calculator runs entirely in your browser. The default numbers are sensible starting points drawn from public specifications and typical regional prices — not exact figures for any one car — and you can edit every input to match your own vehicle and energy prices.
