What Does It Cost to Run a Washing Machine in Washington?
This page estimates the energy-only cost to run a washing machine in Washington using a typical household washing machine, an average load of 700 watts, and a typical runtime of 0.5 hours/day.
Key metrics
| Metric | Value |
|---|---|
| Average wattage assumption | 700 W |
| Typical usage assumption | 0.5 hours/day |
| Estimated monthly electricity use | 10.5 kWh |
| Estimated monthly cost | $1.35 |
| Estimated yearly cost | $16.43 |
Washing Machine cost vs U.S. average
At the statewide average residential rate, running a washing machine in Washington costs less per month by $0.49 than the same usage pattern priced at the current U.S. average electricity rate.
How much electricity does a washing machine use?
This estimate uses a typical wattage range of 400-1,400 W and a modeling assumption of 700 watts for 0.5 hours/day. Using the formula kWh = (watts × hours) / 1000, that works out to 0.35 kWh per day, 10.5 kWh per 30-day month, and 127.7 kWh per year.
Washing machines generally use less electricity than dryers, but hot-water wash cycles can raise total energy cost indirectly. In Washington, that energy is priced using the statewide residential average of 12.86 ¢/kWh, with a national benchmark of 17.57 ¢/kWh for comparison.
Washing Machine operating cost estimate in Washington
| Time period | Energy use | Cost |
|---|---|---|
| Per hour | 0.70 kWh | $0.09 |
| Per day | 0.35 kWh | $0.05 |
| Per month | 10.5 kWh | $1.35 |
| Per year | 127.7 kWh | $16.43 |
These estimates isolate electricity usage only. Real utility bills can be higher because delivery charges, taxes, seasonal pricing, and fixed monthly fees are not included in this appliance model.
What changes the cost the most?
The biggest cost drivers for a washing machine are the local electricity rate and real-world usage intensity. For this appliance, the main swing factors are wash temperature, load frequency, machine efficiency.
If your usage is lighter or heavier than the assumption on this page, the linked state calculator and usage-cost pages below are the fastest way to model a custom scenario with the same state electricity rate.
