How Much Does Electricity Cost Per Month?
The average US household pays about $135-$150 per month for electricity. That figure comes from typical usage of 855-899 kWh per month multiplied by the 2024-2025 average residential rate of roughly 16-17 cents per kWh, according to EIA data. Your actual bill depends on where you live, the size of your home, and how you heat and cool it. Hawaii residents pay over 40 cents per kWh, while Idaho and Washington households pay around 11-12 cents, so the same usage can produce bills that differ by a factor of three or more.
Key Takeaways
- A monthly electric bill is simple multiplication: kilowatt-hours used times your rate per kWh, plus fixed delivery and service charges that typically add $10-$25.
- Time-of-use plans charge 2-3 times more during peak hours (often 4-9 pm), so when you run appliances can matter as much as how long.
- Charging an electric vehicle at home adds roughly 250-400 kWh per month — about $40-$65 at average rates — for a driver covering 1,000 miles monthly.
Explanation
A monthly electric bill is simple multiplication: kilowatt-hours used times your rate per kWh, plus fixed delivery and service charges that typically add $10-$25. To estimate any single appliance, divide its wattage by 1,000, multiply by hours of use, then multiply by your rate. A 1,500-watt space heater running 8 hours a day costs 1.5 kW × 8 h × $0.17 = $2.04 daily, or about $61 a month. Our power cost calculator does this math instantly for any wattage, runtime, and rate.
Heating and cooling dominate most bills, accounting for roughly 40-50% of home energy use. In summer, an air conditioner's electricity draw of 3,000-3,500 watts for a central unit can add $100+ to a monthly bill in hot climates. Water heating is the second-biggest line item at 13-18% of usage; running a water heater typically costs $30-$50 a month for an electric tank model.
Location changes everything. Hawaii's residential rate exceeds 40 cents per kWh because the islands burn imported petroleum for generation, while hydro-rich Idaho and Washington sit near 11-12 cents. New England and California generally run 24-32 cents; the South and Midwest cluster around 12-15 cents. Bills also swing seasonally: a Phoenix home might jump from $120 in March to $280 in July purely from cooling load.
Usage matters as much as rates. A 2,500-square-foot house with electric heat, a pool pump, and an EV can easily consume 1,500-2,000 kWh a month, while an efficient one-bedroom apartment may use only 500-600 kWh. Knowing what uses the most electricity in a home lets you target the big loads first — there are practical ways to save electricity at home that trim 10-25% off a typical bill.
Things to Know
- Time-of-use plans charge 2-3 times more during peak hours (often 4-9 pm), so when you run appliances can matter as much as how long.
- Charging an electric vehicle at home adds roughly 250-400 kWh per month — about $40-$65 at average rates — for a driver covering 1,000 miles monthly.
- Homes with natural gas heating, water heating, and cooking often see electric bills 30-40% below the national average because the largest loads shift to the gas bill.
- Idle devices still draw power: leaving things plugged in uses electricity, and phantom loads can quietly add $8-$15 a month.
- Winter bills can exceed summer ones in cold climates — the cost to run a space heater at 1,500 watts all day rivals central air conditioning.
