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.

Guides
How bills and rate plans work, measured on every plan modeled here and recomputed when the data changes.
- Solar payback by stateHow long a rooftop solar system takes to pay for itself in every state on the largest utility’s actual rate plan, under net metering and with no export credit.
- What uses the most electricityWhere household electricity goes in every state, from EIA’s survey of US homes, and what air conditioning, heating, water heating and the everyday appliances cost a year at today’s prices.
- Electric water heater costWhat an electric water heater costs a year in every state on real rate plans, and what a timer on a time-of-use plan or a heat pump water heater saves.
- Space heater running costWhat a plug-in space heater costs per hour and over a January of evenings in every state, on the largest utility’s actual rate plan, and when the hour of use matters.
- Average electric bill by stateThe typical monthly bill in every state, split into what the price per kWh explains and what household use explains, with each state’s most expensive month.
- Heat pump vs gas, state by stateThe heating bill of a typical gas-heated home with a furnace and with a heat pump on the local utility’s real rate plan, in every state with EIA gas data, and the break-even electricity price.
- Is time-of-use worth it?A typical home’s bill on each utility’s time-of-use plan against its standard plan, with no change in habits, and how much use you would need to move out of the peak to come out ahead.
- Fixed charges and minimum billsWhat utilities charge every month before you use a kWh, why the charge exists, and how it raises the real price per kWh of a small home.
- Tiered rates and baselinesPlans whose price per kWh rises once your monthly use passes a threshold: where the tiers start, how big the step is, and which homes it hits.
- EV rate plans comparedEvery EV and overnight plan modeled here: its cheapest hours, its overnight price, and what 1,000 miles a month cost on it against the utility’s standard plan.
- How to read your electric billFixed charge, energy charge, delivery and supply, riders and taxes: what each line means, worked through on a real tariff for a typical home.
- Electricity price trends by stateHow residential electricity prices moved over the last year and the last ten in every state, from EIA’s monthly data, and what drives the differences.
Every number carries its source and its date.
Tariffs are transcribed from each utility’s own tariff and rider sheets, all charges included, dated and re-checked on a schedule; each plan links its sources and is cross-checked against what the utility actually billed (EIA-861). State prices, gas and gasoline come from the EIA; EV efficiency from the EPA.
