How Much Does It Cost to Run a Dishwasher in West Virginia? (2026)
A dishwasher draws heavy power only while heating water and during the drying phase. Over a full cycle it averages 1 to 2 kWh, which is usually cheaper than washing the same dishes by hand with hot water.
A typical dishwasher (1,500 W) costs $0.22 per hour, or about $6.75 per month at 1 hours a day in West Virginia. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (1,200 W) | $0.18 | $0.18 | $5.40 | $65.70 |
| Typical (1,500 W) | $0.22 | $0.22 | $6.75 | $82.12 |
| High (2,400 W) | $0.36 | $0.36 | $10.80 | $131.40 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 1 h/day ≈ 548 kWh per year.
One hour of a dishwasher (1.5 kWh) is the same electricity as
- 8.3km in an electric car
- 15hours of TV
- 33hours of a laptop
- 167hours of an LED bulb
In West Virginia, with electricity at $0.15 per kWh (source: EIA Table 5.6.A, 2026-06), a typical dishwasher costs $0.22 per hour and about $82.12 per year at 1 hours a day. That is about 17% less than the national average for the US ($8.10 per month), because electricity in West Virginia costs $0.15 per kWh against $0.18 nationally. Each $1.00 of electricity buys roughly 4.4 hours of use.
How to lower the cost of running a dishwasher
- Skip the heated dry option and open the door at the end of the cycle instead.
- Only run full loads, and use the eco program.
- Scrape plates but do not pre-rinse under hot water.
- Connect to cold water if your dishwasher has its own heater and your hot water is electric.
In standby it draws about 1 W, which adds roughly 9 kWh ($1.31) per year if it is never unplugged.
