A 1,500 watt pool pump costs about $2.16 to run for 8 hours at $0.18 per kWh.
Quick estimate
This uses 1500 watts, 8 hours per day, and an electricity rate of $0.18 per kWh.
Pool pump costs can add up because pumps may run for many hours per day during pool season.
Many pool pump units fall around 1500 watts, with a rough range of 700 to 2500 watts. Check the product label, user manual, or manufacturer specifications for the most accurate number.
| Estimate | Watts | Hours per day | Daily cost | Monthly cost |
|---|---|---|---|---|
| Low estimate | 700W | 4 | $0.50 | $15.12 |
| Typical use | 1500W | 8 | $2.16 | $64.80 |
| High estimate | 2500W | 12 | $5.40 | $162.00 |
Pool-pump consumption is shaped by motor size, speed, plumbing resistance, filter condition, and daily circulation schedule. Variable-speed pumps can use much less power at low speed but may run longer.
Wattage input
Use measured input at the programmed speed. Horsepower alone does not provide exact electrical watts, and a variable-speed pump needs separate readings for high-speed cleaning and routine filtration.
Runtime input
Record the hours assigned to each speed and season. Add cleaner, heater, salt system, or water-feature loads separately because the pump estimate does not automatically include them.
Convert watts to kilowatts, multiply by the number of hours used, then multiply by your electricity rate.
Cost = Watts / 1000 x Hours Used x Electricity RateFor this pool pump example: 1500 / 1000 x 8 x 0.18 = $2.16 per day.
These details make this estimate more useful for real-world use.
A pool pump may not have the highest wattage in the home, but it can run for many hours per day. That combination of moderate-to-high wattage and long runtime is why seasonal costs can add up.
Variable-speed pumps can move water at lower power for longer periods, which may use less energy than running a single-speed pump at full power. The best schedule depends on pool size, equipment, and water quality needs.
Use a variable-speed pump or shorter schedules when water quality still stays clear.
The easiest way to improve the estimate is to replace the default values with your actual wattage, average runtime, and local electricity rate.
Wattage ranges are practical planning estimates for common household appliances. Actual use can differ by model, age, settings, room conditions, and maintenance.
These authoritative sources support the calculation method, default electricity-rate benchmark, and appliance-specific operating context. The wattage range remains a planning estimate; use the nameplate on your own appliance for the most accurate input.

Yes. Pump power can fall substantially at lower speed, so a longer low-speed filtration schedule may use less energy than a short high-speed schedule. Actual savings depend on flow needs and equipment.
