EV Range Anxiety Calculator
Enter your EV's full range, a reserve buffer, and your trip distance to calculate how many charging stops you'll likely need.
2 charging stops
Usable range per charge: 200 mi
Keeps a reserve buffer (default 20%) rather than planning to run the battery to empty between stops — real range also varies with speed, weather, and terrain, so treat this as a planning estimate.

Frequently asked questions
Why keep a reserve buffer instead of using the full range?+
