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 × 18.3¢ = $803/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 18.3¢/kWh, about 27.5¢ an hour. That ranges from 19.7¢ in Nevada to 79.1¢ in Hawaii.
What does 8 hours a day add up to?
1500 W × 8 h/day comes to about $66.94 a month ($803 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).
