Pool-pump electricity cost calculator
Calculate pool-pump electricity cost from motor input power, filtration hours, weekly schedule, and your electricity price.
Transparent method
The calculation
Pump cost = input kW × filtration hours × days × tariffPool pumps can become large annual loads because they run for many hours. Variable-speed pumps require a measured or documented average input at the selected speed.

Run three scenarios.
01
Short filtration windowTest the lowest runtime that maintains water quality.
02
Typical scheduleUse the timer's actual daily programme.
03
Peak seasonIncrease runtime for hotter or heavily used periods.
Use the result well
What can change the answer?
- Water-quality requirements come before energy savings.
- Motor horsepower is not always electrical input power.
- Variable-speed power falls non-linearly with speed.
