US Electricity Cost Calculator
U.S. residential EIA benchmark: 18.34¢/kWh ($0.1834) — June 2026 (Table 5.6.A)
The US Electricity Cost Calculator converts electrical power ratings (Watts or Kilowatts) and daily operating hours into monetary expenses. It provides clear breakdowns of hourly, daily, monthly, and annual operating costs using official US EIA benchmark rates or your custom utility tariff.
U.S. residential EIA benchmark: 18.34¢/kWh — June 2026
This is a state/national macroeconomic benchmark from EIA Table 5.6.A, not a guaranteed residential tariff. Your actual electric bill can vary by utility, electricity plan, usage band, fixed customer charges, fees, taxes, riders, and other applicable charges.

Electricity Operating Cost Formula
To compute electricity costs, multiply the electrical load wattage by total operating hours to obtain energy in kilowatt-hours (kWh), then multiply by your volumetric electricity rate.
- Power Rating (Watts): Electrical power demand of the appliance or load (e.g. 1500W for a space heater).
- Operating Hours (hrs/day): Number of hours the device actively draws electricity each day.
- Days in Period: Time horizon for calculation (e.g. 30 days for a monthly billing cycle).
- Electricity Rate ($/kWh): Your electric utility cost per kilowatt-hour ($0.1834/kWh US EIA reference benchmark — June 2026).
Worked Example: 1,500-Watt Space Heater Running 8 Hours Daily
Calculating the daily, monthly, and annual cost to operate a standard 1,500W portable space heater for 8 hours per day at the US benchmark rate of $0.1834/kWh (18.34¢/kWh):
Calculation Assumptions & Cost-Saving Strategies
- Assumes steady-state electrical power consumption during active hours.
- Duty cycles for cycling equipment (compressors, refrigerators) can be represented by effective run hours.
- Default rate is the U.S. EIA Table 5.6.A residential benchmark (18.34¢/kWh — June 2026).
Eliminate Phantom / Standby Loads
Electronics drawing vampire power on standby cost average US homes $100–$200 per year. Use smart power strips.
Switch to LED Lighting
LED bulbs consume 75% less electricity than incandescent bulbs and last up to 25 times longer.
Clean HVAC Filters Regularly
A dirty air filter forces blower motors to draw up to 15% more power and reduces cooling efficiency.

Frequently Asked Questions: US Electricity Cost Calculator
How do I find the wattage of my appliance? +
Check the manufacturer label on the back or bottom of the device (often listed as "Input: XXX W" or calculated as Volts × Amps = Watts).
How much does 1,000 Watts cost to run for 1 hour in the US? +
1,000 Watts running for 1 hour equals exactly 1 kilowatt-hour (1 kWh). At the EIA national benchmark rate of 18.34¢/kWh (June 2026), it costs approximately 18.34 cents per hour.
What appliances consume the most electricity in American homes? +
Central air conditioning and heating systems consume over 45% of total home energy, followed by water heaters (18%), clothes dryers (5%), and refrigerators (4%).
