Why this number

Running a washing machine at 500 watts for 0.6 hours a day costs about $0.05 a day and $0.88 a month at 17¢/kWh, the EIA 2025 annual US average (July 2026 monthly: 18.31¢) — roughly $11 a year. The formula for a washing machine: 500 W ÷ 1,000 × hours × your rate per kWh. For a washing machine your own rate changes the answer: at 12¢/kWh that month costs $0.62, at 45¢/kWh it costs $2.34.

A washing machine rated at 500 watts, run 0.6 hours a day, costs about $0.05 a day — about $0.88 a month, or $11 a year — at the US average electricity rate of 17¢/kWh. That places it 39th of the 40 appliances tracked here, near the bottom. It is not where a high bill comes from, and switching it off will not rescue one.

What actually drives this number

The motor uses little; the cost is in hot water, which is billed to your water heater rather than to the machine. Washing cold is therefore a far bigger saving than the machine’s own rating suggests. About four loads a week.

For a washing machine the unit that matters is the kilowatt-hour, not the kilowatt : 500 W is only the rate of use, and 0.6 hours a day is what turns it into the 62 kWh a year you are actually billed for. On that yearly measure its nearest always-on neighbor is the water softener at about 26 kWh.

Where this number comes from

Putting Washing machine in proportion

At 17¢/kWh, a washing machine next to the rest of the bill:

For a washing machine: this is an always-on load, and that is the whole story. Washing machine’s wattage is unremarkable; the 24-hour duty cycle is what puts a washing machine where it is. Reducing run-hours is usually impossible for a washing machine, which makes efficiency at purchase time the only real decision. On this site’s own numbers, a washing machine lands at #39 of 40 on the monthly-cost ranking, at about $0.88 for a typical month.

The formula, in full

The 500 W arithmetic for a washing machine, step by step:

  1. Watts to kilowatts. 500 W ÷ 1,000 = 0.50 kW.
  2. Energy per day. 0.50 kW × 0.6 hours = 0.30 kWh.
  3. Cost per day. 0.30 kWh × $0.17 = $0.05.
  4. Cost per month. $0.05 × 17.3 days = $0.88.

For a washing machine the two levers are run-hours (0.6 h/day here) and your rate; used this briefly, even 500 W costs little — which is why always-on loads dominate the rankings.

Other always-on loads: Water softener ($4/yr), Wi-Fi router and modem ($22/yr), LED grow light ($27/yr). Closest on annual cost: CPAP machine ($11/yr), Ceiling fan ($11/yr). Across all other always-on loads here, the priciest is Pool pump at $40.80/mo.

Frequently asked questions

How much does it cost to run a washing machine per hour?

About $0.085 an hour for a washing machine at 17¢/kWh, the EIA 2025 annual US average (July 2026 monthly: 18.31¢), for a 500 W unit. The calculation is 500 ÷ 1,000 × 1 hour × $0.17 per kWh. At 30¢/kWh the same hour costs $0.150.

How much does a washing machine add to my monthly bill?

Roughly $0.88 a month for a washing machine at 0.6 hours a day, 17.3 days a month, 17¢/kWh. That is about $11 a year if you use it that much year-round. For a washing machine, change the 0.6-hour default to your own use — run-time moves the total as much as the 500 W does.

How many watts does a washing machine use?

Typically around 500 W, with real units ranging from about 300 to 1,000 W depending on size, model and setting. The nameplate on your own unit is the figure to trust — these are typical values for planning, not a measurement of your appliance.

Why is my actual bill higher than the a washing machine figure?

$0.88 a month is the energy cost of a washing machine alone; your bill adds fixed connection charges, delivery fees, taxes and every other load. Add the other appliances in the index to a washing machine for the controllable part of the bill.

How we calculated this

Worked for a washing machine: 500 W ÷ 1,000 × 0.6 h × $0.17 = $0.05 a day; × 17.3 days = $0.88 a month; × 12 months in use = $11 a year. 500 W and 0.6 h are the typical figures cited for a washing machine; 17¢ is EIA’s 2025 annual US average.
