HomeWattCost

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.

The four dials read 1-8-3-1: 18.31¢ per kWh, the EIA US average residential price for July 2026.

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.

Six calculators, one tariff engine

Each one reads the same rate data: periods, tiers, seasons and fixed charges. The figures beside them are live results from that engine.

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.
