EV road trip cost calculator

How many charging stops, how much electricity, and how much you save versus gas.

How the estimate works

We assume you leave at 90% and fast-charge from 10% to 80% — the fastest part of the charging curve. Each stop is about 30 minutes. Cold weather, high speed and towing can cut range by 20–40%, so plan a buffer.

Home charging vs fast charging

Home electricity is often $0.12–0.20 per kWh; highway fast chargers run $0.35–0.60. Charging overnight at a hotel with a Level 2 charger is usually the cheapest way to add range on a road trip.
