Pool Pump running cost calculator
These are estimates, not certified measurements.
Wattages reflect measured operating points from the ENERGY STAR certified pool pump dataset (certification covers pumping efficiency, gal/Wh — annual kWh depends entirely on your run schedule).
Pool pumps are one of the biggest hidden loads in a home — a single-speed pump on a long schedule can out-consume a refrigerator several times over. Variable-speed models running slower for longer cut the bill dramatically.

1,500 W × 8 h/day × 365 ÷ 1,000 = 4,380 kWh/yr × 18.8¢ = $825/yr
Eight hours a day is a common turnover schedule for residential pools in season.

Questions, answered with the data
- How much does a pool pump cost per hour?
- At a typical 1500 W draw and the U.S. average rate of 18.8¢/kWh, about 28.2¢ an hour. That ranges from 18.5¢ in North Dakota to 69.9¢ in Hawaii.
- What does 8 hours a day add up to?
- 1500 W × 8 h/day comes to about $68.73 a month ($825 a year) at the U.S. average rate. Eight hours a day is a common turnover schedule for residential pools in season.
- Why is this an estimate instead of certified data?
- Wattages reflect measured operating points from the ENERGY STAR certified pool pump dataset (certification covers pumping efficiency, gal/Wh — annual kWh depends entirely on your run schedule).
