Calculate the daily, monthly, and annual electric bill of running your pool pump. Enter the values shown in the calculator to get a practical planning estimate.
Calculate your daily, monthly, and seasonal electric bill from running your swimming pool filtration pump.
The pool pump electricity cost calculator estimates power consumption (kWh) and electric utility costs for single-speed, dual-speed, and variable-speed pool pumps. Compare running costs across daily schedules and energy rates.
Pool pumps are often the second-largest electricity consumer in a home after central air conditioning. Calculating runtime wattage helps you optimize filtration schedules and evaluate energy savings from modern variable-speed pumps.
Note: Pump motors draw more current under higher system resistance (total dynamic head). Use measured wattage if you have an energy monitor.
A standard 1.5 HP single-speed pool pump consumes approximately 1.5 to 2.0 kWh per hour. Running 8 hours daily at $0.16/kWh costs about $60 to $80 per month. A variable-speed pump running at lower RPM can reduce this to $15 to $25 per month.
According to the US Department of Energy, variable-speed pool pumps use up to 70% less energy than standard single-speed pumps because pump power follows the affinity law (halving the speed cuts energy use by nearly 85%).
If your electric utility has Time-of-Use (TOU) rates, run your pool pump during off-peak hours (usually late night and early morning) when electricity rates are lowest.
