Pool Pump running cost, by state
A pool pump drawing 1500W costs about $803 a year at the US average electricity rate — but that average hides a fourfold spread. Pick your state for a real figure.
At the US average rate
1500W , 8 hours a day, at 18.34¢/kWh.
About this appliance
Single-speed pool pumps are among the largest discretionary loads in a home. Variable-speed models running longer at lower speed use dramatically less energy for the same filtration.
- At typical use this is a major load - around 4,380 kWh a year. Efficiency upgrades here pay back faster than on any small appliance.
- Models vary widely, from about 750W to 2500W. Check the nameplate on your own unit rather than assuming an average, because the spread is more than 2x.
- If your utility offers time-of-use pricing, shifting this load off-peak can cut its cost substantially without using any less energy.

Common questions
How many watts does a pool pump use?
A typical pool pump draws about 1500 watts while running, with most models falling between 750W and 2500W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.
How much electricity does a pool pump use per day?
At around 8 hours of use a day and a 100% duty cycle, that works out to roughly 12 kWh per day, or about 360 kWh a month. Your actual figure depends on your usage and model.
Why does the cost differ so much between states?
Residential electricity rates across the US range from about 12.35 cents per kWh in North Dakota to 46.62 cents in Hawaii - nearly a fourfold difference. The same pool pump, used identically, therefore costs almost four times as much to run in the most expensive state as in the cheapest.
Is it cheaper to run a pool pump at night?
Only if you are on a time-of-use or variable tariff. On a flat rate, the time of day makes no difference to cost. If you are on time-of-use pricing, off-peak hours are typically materially cheaper, and shifting this load can reduce its cost without reducing usage.
