Electric Bill Estimator
Estimate your monthly electricity bill based on your rate, home size, climate zone, and major appliances. See seasonal variation and tips to reduce costs.
Reviewed September 17, 2026. JouleIO calculators are planning tools; confirm final utility rates, equipment specs, incentives, installation bids, and safety decisions with official utility, manufacturer, installer, DOE, ENERGY STAR, EPA, IRS, or EIA sources.
1. Enter real usage
Use your actual watts, runtime, home size, miles, battery size, or appliance schedule.
2. Localize the rate
Compare national assumptions with your state, utility bill, time-of-use plan, or project quote.
3. Verify before acting
Check final prices, rebates, tax rules, and safety requirements before buying or installing equipment.
Quick answer
At the EIA U.S. average residential rate of 18.16¢/kWh (June 2026), a household using 1,000 kWh a month pays about $181.60 in energy charges; 500 kWh costs $90.80 and 1,500 kWh costs $272.40, before fixed customer charges and taxes. The same 1,000 kWh ranges from $127.20 in Nevada to $471.80 in Hawaii. Pick your state below, then enter home size, occupants and appliances to estimate your own monthly, summer and winter bills.

Tips to Reduce Your Bill
- Set your thermostat 2 degrees higher in summer and lower in winter to save 5-10% on HVAC costs.
- Run the dishwasher and laundry during off-peak hours if your utility offers time-of-use rates.
- Unplug electronics not in use, standby power ("phantom load") can add $100+ per year.
- Use a smart power strip to automatically cut power to devices in standby mode.
- Switch to LED bulbs, they use 75% less energy and last 25 times longer than incandescent.
- Consider a heat pump water heater, it uses 60% less energy than a standard electric water heater.
Monthly bill for a 1,000 kWh household, by state

How to Use This Estimate Without Undercounting
1. Start with the rate baseline
The default rate comes from the JouleIO EIA residential dataset: 18.16¢/kWh for 2026-08. State averages are useful for planning, but your bill may include riders, delivery charges, or time-of-use prices.
2. Use bill kWh when possible
Home size and appliance choices estimate usage. For the most accurate answer, compare this result with total kWh from your last utility statement, then test individual loads in the appliance calculator.
3. Model seasonality separately
HVAC can dominate summer or winter bills. Hot-dry and hot-humid climates push cooling higher, while cold zones shift the peak to electric heat and water heating.
4. Check solar and electrification impact
If the bill is high because of EV charging, heat pumps, or pool equipment, compare the result with the solar savings calculator and home electrification planner.

Frequently Asked Questions
What is the average electric bill in the US?
The average US household pays roughly $137/month for electricity in recent EIA annual utility data, but current rate pressure varies widely by state. This estimator starts with the JouleIO EIA residential rate baseline of 18.16 cents/kWh for 2026-08, then lets you choose a state or override the rate from your bill.
Why is my electric bill higher in summer?
Air conditioning is the primary driver of summer electricity spikes. Central AC can use 3,000+ kWh during a hot summer, adding $400-500+ to your seasonal bill. Hot-humid and hot-dry climates see the biggest summer increases.
How much does an EV add to my electric bill?
A typical EV driven 12,000 miles/year adds about 310 kWh/month or roughly $50/month at the national average rate. This is still 50-70% cheaper than gasoline for the same miles.
How much is an electric bill for 1,000 kWh a month?
At the EIA U.S. average residential rate of 18.16 cents/kWh (June 2026), 1,000 kWh costs $181.60 in energy charges before fixed customer charges and taxes. The same 1,000 kWh runs $127.20 in Nevada, the cheapest state, and $471.80 in Hawaii, the most expensive.
Which states have the cheapest and most expensive electric bills?
Per EIA June 2026 residential prices, the five cheapest states are Nevada (12.72 cents), Louisiana (12.87 cents), North Dakota (13.31 cents), Utah (13.31 cents), Idaho (13.37 cents). The five most expensive are Hawaii (47.18 cents), Maine (32.11 cents), Massachusetts (30.48 cents), California (29.75 cents), Alaska (29.41 cents). For a 1,500 kWh month that is a spread from $190.80 to $707.70 on the energy charge alone.
Why is my estimate lower than my actual bill?
This estimator prices kWh at a state-average energy rate. Real bills add a fixed customer charge (often $10-$30/month), delivery or transmission riders, fuel adjustment clauses, taxes and, on tiered or time-of-use plans, higher prices for part of your usage. Enter the fixed charge from your bill and, if your effective all-in rate (total bill divided by kWh) is higher than the state average, type that rate instead.
