How much does it cost to run a pool pump?

A pool pump is one of the most expensive appliances most people never think about. A single-speed pump draws around 2,000 watts and runs many hours a day all summer — easily 16 kWh a day. That's often the real reason a poolside summer bill balloons. The fix is mostly about speed and hours.

Runs many hours a day — a big summer bill driver. Variable-speed pumps use far less.

Running a 2000W pool pump (single-speed) 8 hours a day costs about $1.99/day or $60.69/month at 12.46¢/kWh.

Pool pump type and daily energy

Pump typeTypical draw8-hour energyNotes
Single-speed~2,000 W~16 kWhThe big driver; runs at full power always
Two-speed (low)~800 W~6.4 kWhRuns filtration on low most of the time
Variable-speed100–800 W~2–5 kWhUp to ~80% less energy; pays back fast

Energy depends on pump size and run hours. Variable-speed pumps save the most because power rises steeply with speed.

How to cut the cost

  1. 1

    Upgrade to a variable-speed pump

    This is the single biggest saver — running filtration at low speed for longer uses up to 80% less energy than a single-speed pump at full blast. Many utilities even offer rebates.

  2. 2

    Run it fewer hours

    Most pools don't need 8+ hours of filtration. Try cutting back an hour at a time; if the water stays clear, keep it there.

  3. 3

    Run during off-peak hours

    If you're on a time-of-use rate, schedule the pump for off-peak overnight hours to cut the per-kWh cost.

  4. 4

    Keep the filter and baskets clean

    A clogged filter makes the pump work harder for the same circulation. Clean baskets and backwash on schedule.

Common questions

How much does it cost to run a pool pump per month?
A single-speed pump running 8 hours a day uses about 480 kWh a month — roughly $60–$80 at typical rates. A variable-speed pump can drop that to $15–$25.
Why is my electric bill so high in summer with a pool?
The pump is usually the culprit. A single-speed pump running all summer can add $60–$80 a month on its own — often more than the air conditioning. It's the most overlooked summer load.
How many hours a day should I run my pool pump?
Enough to turn the water over once or twice — for many pools that's 6–8 hours, but often less. Start lower and increase only if the water clouds. Fewer hours directly cuts the cost.
Do variable-speed pool pumps save money?
A lot. Because power rises steeply with pump speed, running slower for longer uses up to 80% less energy than a single-speed pump. The savings typically pay back the higher purchase price within a couple of seasons.

Hiring out the wiring?

Before you pay anyone to touch your panel or wiring, make sure they're actually licensed. You can check a contractor's license on StateCreds — our sister site.

If the summer bill jumped more than usage explains, your rate may have risen too.
