How the math works: 1,500 W × 8 hours ÷ 1,000 = 12 kWh a day. × 30 days = 360 kWh a month. × $0.165 per kWh (the 2024 U.S. average) = about $59.40 a month.
A pool pump typically draws 900 to 2,100 watts depending on its horsepower rating, and because it commonly needs to run several hours a day for proper filtration, it's often one of the biggest single electricity costs of owning a pool.
What affects how much electricity a pool pump uses
- Horsepower: a 1.5 HP pump draws considerably more than a 1/2 HP pump.
- Daily run time: a bigger pool generally needs more hours of filtration to circulate its water volume.
- Pump type: a variable-speed pump run at low speed for more hours is often cheaper to operate than a single-speed pump at full power for fewer hours, even when both filter a similar volume.
How to reduce your pool pump's electricity use
- Run the pump during off-peak electricity hours if your utility offers time-of-use pricing
- Consider a variable-speed pump if replacing an older single-speed model; running it slower for more hours often costs less than running a single-speed pump at full power
- Use a timer so the pump doesn't run longer than the pool actually needs for filtration
- Keep the filter and skimmer baskets clean, since clogs make the pump work harder to maintain flow
Typical wattage figure: roughly 900-2,100 W depending on pump size (1/2 HP to 1.5 HP). Source: Jackery: Appliance Wattage Chart. This is a commonly cited commercial estimate, not a government-published figure. A variable-speed pump run at a lower setting for more hours a day typically costs less than a single-speed pump run for fewer hours, even though this range doesn't capture that difference. We review this figure periodically and update it if the source changes; last checked September 2026.

Frequently asked questions
How many watts does a pool pump use?
A pool pump typically draws 900 to 2,100 watts depending on horsepower, based on a commonly cited commercial wattage reference chart. This is not a government-published figure; check your specific pump's nameplate for its rated wattage.
How much does it cost to run a pool pump?
A 1,500-watt pump run 8 hours a day at the U.S. average rate of about 16.5 cents/kWh costs roughly $1.98 a day, or about $59 a month during swim season. Use the calculator above with your own pump's wattage and typical runtime for an exact figure.
Does a variable-speed pool pump really save money?
Often, yes. A variable-speed pump can run at a lower, more efficient speed for a longer stretch of the day and still filter the same water volume as a single-speed pump running briefly at full power, and pump efficiency generally improves faster than runtime increases at lower speeds.
How can I reduce how much electricity my pool pump uses?
Use a timer so it only runs as long as the pool actually needs for filtration, keep filters and skimmer baskets clean so the pump isn't fighting a clog, and run it during off-peak hours if your utility charges different rates by time of day.
