How much does it cost to run a pool pump?
We've pre-filled a typical pool pump below. Set your electricity rate and adjust the hours to match how you use yours — the cost updates instantly.
A single-speed pool pump pulls ~1,500W and often runs 8+ hours a day — a top summer cost.

A pool pump is one of the most expensive appliances most owners never think about. A single-speed pump draws around 1,500W and is often set to run eight hours or more every day through the season — which quietly makes it one of the biggest line items on a summer bill, rivaling the air conditioning.
The good news is that pumps are wildly over-run by default: you usually need far fewer hours than the timer is set for, and a variable-speed pump changes the math entirely — run on its low setting it can draw as little as 200–300W instead of 1,500W, so a variable-speed owner's real cost can be a third of the single-speed figure this page starts from. If that's you, drag the wattage down to match.
What drives the cost of running a pool pump
- Run hours — most pumps are set to run far longer than the water actually needs.
- Single- vs. variable-speed — a single-speed pump runs flat-out at ~1,500W with no low gear, while a variable-speed pump on low sips a few hundred watts.
- An oversized pump or a dirty filter makes it work harder for the same circulation.
How to cut it
- Cut the daily run time — many pools stay clean on 4–6 hours, not 8–12.
- A variable-speed pump run slower for longer uses a fraction of the energy (often the single best pool upgrade).
- Run it during off-peak hours if you're on time-of-use pricing.
- Keep the filter and skimmer clean so the pump isn't straining.
What different sizes of pool pump draw
The typical figure above is a middle-of-the-road unit. Since a pool pump is sold by pump type and speed, here's the running power to expect across the common sizes — set the wattage to match yours for an exact cost.
| Pump type | Typical running power | |
|---|---|---|
| Variable-speed (low) | 300W | everyday filtering — how you should run a VS pump most of the day |
| Variable-speed (high) | 1,800W | vacuuming, spa jets, or a quick fast turnover — full speed draws like a single-speed |
| Single-speed (1.5 HP) | 2,000W | typical older/standard pump, runs flat-out whenever it's on |
| Single-speed (large, 2 HP) | 2,500W | bigger pool or long plumbing runs |
Common questions
How much does it cost to run a pool pump per month?
At a typical 1,500W and about 8 hours a day, a pool pump costs roughly $61 a month at $0.17/kWh. Set your own rate and hours above for an exact figure.
How can I cut the cost of running a pool pump?
Cut the daily run time — many pools stay clean on 4–6 hours, not 8–12.
How much cheaper is a variable-speed pool pump to run?
A lot. A single-speed pump runs flat-out at around 1,500W, but a variable-speed pump on its low circulation setting can draw only 200–300W and still keep the water clean — often cutting the pump's share of the bill by half to two-thirds. It's usually the single best cost upgrade for a pool.
