How the washing machine estimate works
The calculator converts watts to kilowatts, multiplies by effective runtime, and then applies the electricity price. With the starting inputs, this washing machine uses about 5.6 kWh per month.
Cycle choice, load size, water temperature, spin speed, and machine type determine total energy use.
How runtime changes the estimate
These scenarios assume the device draws the full starting wattage for the entire runtime. Cycling and variable-speed equipment should use effective runtime or measured kWh.
Estimated monthly cost in high-price states
Practical ways to reduce cost
- Wash with cold water when appropriate.
- Run full loads without overfilling.
- Use a high spin speed to shorten dryer time.

Frequently asked questions
How much electricity does a washing machine use?
Using a 500-watt starting input for 0.75 hours per day and 15 days per month produces an estimate of 5.6 kWh per month. Actual use can differ because equipment may cycle or change power.
How much does it cost to run a washing machine each month?
At the latest 2026-05 U.S. residential average price of 18.44 cents per kWh, the starting estimate is $1.04 per month. Replace the inputs with your own numbers for a personal estimate.
What number should I use for the electricity price?
Divide the total electric charges on your latest bill by the total kWh used for an all-in price. State averages are useful for comparison but are not utility-specific rates.
