Home rate default $0.1831/kWh is the EIA U.S. residential average for July 2026 (published Sep 24, 2026). The $0.45/kWh DC fast-charging rate is an illustrative scenario, not an EIA figure. Confirm local fuel and electricity rates before planning.

How we calculate EV electricity cost

Distance × kWh per 100 miles ÷ 100 gives traction energy. Dividing by charging efficiency estimates energy purchased from chargers; we then apply the home and fast-charging rate mix you enter.

A useful charging example

300 miles × 30 kWh/100 mi = 90 kWh delivered to the battery. At 90% assumed charging efficiency, the purchased energy is 100 kWh. At $0.1831/kWh (EIA U.S. residential average, July 2026), energy would cost $18.31.

Charging station availability is not predicted

This calculator does not show verified charger locations, route charging time or live station status. Those require a licensed provider and vehicle-specific charging data.

Frequently asked questions

What does charging efficiency mean?

It is the share of purchased electricity delivered to the vehicle battery in the simplified model.

Does this predict charging stops?

No. It estimates electrical cost and energy based on a user-entered charging mix.
