What your electricity actually costs.
On PG&E’s EV2-A plan, the same kWh costs 22.6¢ at 12 am and 53.8¢ at 4 pm on a July weekday. HomeWattCost prices your car, your appliances and your plan from your utility’s real tariff, not a national average.
Or jump to EV charging cost, compare rate plans, rates by state.
Same car. Same 50 kWh. Different hour.
On PG&E’s EV2-A plan, that charge costs $11.28 started at midnight and $25.33 started at 3 pm. Averages cannot show you this; the tariff can.

Electricity prices by state
Average residential price, July 2026 (EIA). Pick a state for its utilities, plans and 13-month trend.
Every number carries its source and its date.
Tariffs come from the OpenEI Utility Rate Database, re-read every month; each plan shows its effective date and links the utility’s own tariff document, and a plan is dropped if its price stops matching what the utility actually billed (EIA-861). State prices, gas and gasoline come from the EIA; EV efficiency from the EPA.
