How Much Does It Cost to Run a Washing Machine in Arizona? (2026)
Most of a washing machine's electricity goes to heating water, not spinning the drum. A cold wash uses a fraction of the power of a hot one, which is why the low and high figures differ so much.
A typical washing machine (500 W) costs $0.076 per hour, or about $2.28 per month at 1 hour a day in Arizona. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 400 W | $0.061 | $0.061 | $1.82 | $22.16 |
| Typical 500 W | $0.076 | $0.076 | $2.28 | $27.70 |
| High 1,300 W | $0.20 | $0.20 | $5.92 | $72.03 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 1 h/day ≈ 182 kWh per year.
One hour of a washing machine (0.50 kWh) is the same electricity as
- 2.8km in an electric car
- 5.0hours of TV
- 11hours of a laptop
- 56hours of an LED bulb
In Arizona, with electricity at 15.2¢ per kWh (source: EIA Table 5.6.A, 2026-06), a typical washing machine costs $0.076 per hour and about $27.70 per year at 1 hour a day. That is about 17% less than the national average for the US ($2.75 per month), because electricity in Arizona costs 15.2¢ per kWh against 18.3¢ nationally. Each $1.00 of electricity buys roughly 13.2 hours of use.
How to lower the cost of running a washing machine
- Wash in cold water. Modern detergents are designed for it and it cuts consumption by up to 90 percent.
- Run full loads and use the eco cycle even though it takes longer.
- A higher spin speed uses slightly more power but saves far more on drying.
- Front loaders generally use less water and electricity than top loaders.
In standby it draws about 1 W, which adds roughly 9 kWh ($1.33) per year if it is never unplugged.
Is an efficient washing machine worth it?
Class G washer, about 90 kWh per 100 cycles: about 200 kWh a year. Class A washer, about 47 kWh per 100 cycles: about 105 kWh. The difference is worth $14.42 a year in Arizona.
- Replacing one that still works pays back in 41.6 years.
- When yours needs replacing anyway, the extra cost of the efficient model pays back in 10.4 years.
Usage assumed: 220 cycles a year. Typical prices: $600.00 for the efficient model, $150.00 more than a basic one. Work it out with your own prices
Frequently asked questions
How much electricity does a washing machine use per load?
Around 0.3 kWh for a cold wash and 1 to 2 kWh for a hot wash.
Is the eco cycle really cheaper?
Yes. It heats water more slowly and to a lower temperature, which uses less energy despite the longer run time.
Does the washing machine use power when off?
About 1 watt in standby on most models, which is negligible.
