How It Works?
Each calculator uses your vehicle’s real numbers — battery capacity, efficiency (miles per kWh), electricity rate, and charge percentage — and runs them through the standard formula for that metric, whether it’s range (battery × efficiency), charging time (energy needed ÷ charger power), or cost savings versus a gas car. Everything happens instantly in your browser as you type, so you can test different scenarios side by side without reloading the page.
FAQ
You’ll get the most accurate results with your EV’s actual battery capacity and efficiency rating, both usually listed in your owner’s manual or on the manufacturer’s spec sheet. If you’re not sure, the pre-filled default values represent a typical mid-size EV and still give you a useful ballpark estimate.
These calculators give a straight-line theoretical estimate based on your inputs, while your car’s onboard system also factors in real-time variables like speed, terrain, weather, and driving style. Treat the calculator result as a planning baseline rather than a guaranteed number.
Yes — the EV vs. Gas and Savings calculators are built for exactly that. Plug in your annual mileage along with both vehicles’ efficiency and local fuel/electricity prices to see the yearly cost difference.
No, all 13 calculators are completely free and run directly in your browser with no sign-up, download, or data collection required.
