Typical electricity cost
How much does a Pressure Washer cost to run?
Based on typical usage
A Pressure Washer typically uses about 1,800 watts, costing around $0.27 per hour at $0.15 per kWh.
At typical use (0.5 hours per day), that's about $4.05 per month and $24.30 for a typical 6-month outdoor season.
Based on
- 1,800 watts
- 0.5 hours per day
- $0.15 per kWh
- 6-month outdoor season
What affects cost most
- Average hours used per day
- Electricity rate in dollars per kWh
- How many active days or months the device runs each season
- Pump size, maintenance, and season length
How it works: Daily cost uses wattage, hours per day, and electricity rate. Monthly uses daily × 30; outdoor season uses monthly × 6.

Get a better estimate and keep costs down
Defaults are a starting point. Real cost changes most when runtime, wattage, and your electricity rate differ from the benchmark assumptions.
What changes cost most
- Average hours used per day
- Electricity rate in dollars per kWh
- How many active days or months the device runs each season
- Pump size, maintenance, and season length
How to get a better estimate and lower cost
- Replace the default electricity rate with the actual rate from your latest power bill.
- Adjust daily runtime to match how long you actually use the equipment.
- Do prep work first so the washer runs for less total time.
- Use the correct nozzle to finish faster without extra passes.
- Turn the machine off between longer repositioning breaks.
- Keep hoses and filters clear so the motor does not strain.
