This calculator compares what you pay to drive an EV against a gas, petrol, or diesel car using local electricity prices, fuel prices, vehicle efficiency, and charging-loss assumptions. It is built for quick side-by-side comparisons in miles or kilometers.
If you want the bigger financial picture, use the ownership calculator. If you want to understand wall-to-battery losses before entering numbers, read the EV charging losses guide.
The comparison is most useful when you use your own tariff, your own driving distance, and realistic efficiency numbers. Public charging, winter driving, and high-speed motorway use can move the result more than people expect.
No. EVs are usually cheaper when you charge at home with sensible electricity rates. If you rely on expensive public charging, the gap can shrink a lot or disappear.
Usually yes. A practical estimate is around 5-15% depending on the charger, weather, and car. That is why this tool includes a charging-loss input instead of assuming battery energy equals wall energy.
Yes. The tool is meant for cross-market comparisons, so you can switch locale, units, and prices without needing a different calculator for each fuel type.
