EV Range Calculator
Estimate how far your EV will actually go — adjusting for temperature, driving speed, and style, which all cut into the EPA sticker range.

How range is estimated.
Charging to only 80% is recommended for daily use to preserve battery life — DC fast-charging also slows dramatically above 80%.
Frequently asked questions.
How much does cold weather reduce EV range?
Range can fall 20–40% in freezing temperatures. Batteries are less efficient when cold, and cabin heating draws significant power. Preconditioning while plugged in helps a lot.
Does highway driving use more energy than city?
Yes — unlike gas cars, EVs are most efficient in city driving thanks to regenerative braking. Sustained highway speeds above 70 mph can cut range 15–20%.
Should I charge to 100%?
For daily driving, most manufacturers recommend charging to 80–90% to extend battery lifespan. Save 100% charges for long trips.
