How Much Does It Cost to Run a Electric Pressure Washer in the US? (2026)
Electric pressure washers draw 1,300 to 2,500 watts but only while the trigger is pressed. An hour of washing typically uses about 1 kWh, and the water cost is often larger than the electricity.
A typical electric pressure washer (1,800 W) costs $0.32 per hour, or about $4.86 per month at 0.5 hours a day in United States (average). Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (1,300 W) | $0.23 | $0.12 | $3.51 | $42.70 |
| Typical (1,800 W) | $0.32 | $0.16 | $4.86 | $59.13 |
| High (2,500 W) | $0.45 | $0.22 | $6.75 | $82.12 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.5 h/day ≈ 328 kWh per year.
In the US, with electricity at $0.18 per kWh (source: EIA Electric Power Monthly, 2026-06), a typical electric pressure washer costs $0.32 per hour and about $59.13 per year at 0.5 hours a day. Each $1.00 of electricity buys roughly 3.1 hours of use.
How to lower the cost of running a electric pressure washer
- Use the widest nozzle that does the job. Narrow nozzles do not use more electricity but take longer.
- Pretreat with detergent so you rinse rather than blast.
- Store it drained and indoors so the pump lasts.
