How many watts does a washing machine use?
A washing machine uses 400–1,400 W (about 700 W on average). Running 0.5 hours/day, that is about 0.35 kWh a day and 10.5 kWh a month — roughly $1.92 a month at the U.S. average rate of 18.31 ¢/kWh.
This is the washing machine electricity usage reference: watts, amps on a 120 V circuit, the kWh math, and links to what that usage costs in each state.
Watts, amps, and kWh for a washing machine
| Measure | Value |
|---|---|
| Rated wattage range | 400–1,400 W |
| Average draw used in our math | 700 W |
| Amps at 120 V | 3.3–12 A (5.8 A at the average draw) |
| kWh per hour | 0.70 kWh |
| kWh per day at 0.5 hours/day | 0.35 kWh |
| kWh per month | 10.5 kWh |
| Cost per month at the U.S. average (18.31 ¢/kWh) | $1.92 |
The math is kWh = watts × hours ÷ 1000 and amps = watts ÷ volts. A standard 120 V household circuit on a 15 A breaker carries about 1,800 W. For the dollars in your state, open cost to run a washing machine in Texas and switch states from there.

Frequently asked questions
How many watts does a washing machine use?
A washing machine uses 400–1,400 W (about 700 W on average). Our usage and cost math uses 700 watts running 0.5 hours/day.
How many amps does a washing machine draw?
On a 120 V circuit, 400–1,400 W works out to about 3.3–12 A; at the 700 W we use in the math that is 5.8 A.
How much electricity does a washing machine use per month?
About 10.5 kWh a month at 0.5 hours/day. Lighter use (0.5 hours/day) comes to roughly 10.5 kWh and heavier use (2.5 hours/day) roughly 52.5 kWh.
How much does it cost to run a washing machine?
About $1.92 a month at the U.S. average rate of 18.31 ¢/kWh — from roughly $1.34 in Louisiana to $5.04 in Hawaii at the same usage. The state cost-to-run pages price it at every state's rate.
