How Much Electricity Does a Pool Pump Use per Month?
A pool pump’s monthly electricity use depends on wattage, run time, and pump speed. Estimate it from the nameplate and your daily hours of operation.

The amount of electricity a pool pump will draw is variable; it can be modest or substantial based on the unit’s wattage and efficiency as well as your daily running habits. For a ballpark figure on what to expect from your electric bill, one need only consult the nameplate, do some simple math with the hours per day and wattage, and put it in kilowatt-hours.
What are the factors in energy usage?
Several things will drive up consumption:
- The size and make of the pump
- How many hours it is left on
- Whether it is a single-speed, two-speed or variable-speed model
- Any resistance caused by a clogged filter, poor circulation or dirty baskets
Then there is the matter of the overall circulation system. Hayward would have you consider the skimmer, drains, strainer and filter as part of that equation, all of which must work in concert for proper filtration. If any of those components are restricted, the pump has to run longer to see results.
Estimating your monthly bill
To get an idea of your monthly use, follow this procedure:
1. Note the wattage from the manual or label. 2. Take that number and multiply by the daily run time. 3. Divide by 1,000 for your kWh per day. 4. A rough monthly total is found by multiplying by 30. 5. Apply your rate for an estimate of the cost.
By way of example, 1,500 watts at 8 hours gives you 12 kWh a day, or 360 kWh over the course of a month. But it is an estimate at best. In reality, usage is subject to the condition of the pump, the size of the pool, plumbing resistance and how often one has to add run time for cleaning or heavy use.
Is there a typical range?
You will not find one number that applies to every backyard pool, though the trend is easy to spot. A variable-speed pump on a low setting is far more frugal than an older, larger single-speed type. And if you employ a pool cleaner, be aware that some systems require a booster pump on top of the regular one, adding to the running costs.
For those looking to curb expenses, the better question may be “How long does the water actually need to be filtered and balanced?” rather than simply “How much power is the pump using?”
Maintenance and higher power draw
A dirty or restricted system will force a pump to work harder. One should check for debris in the skimmer or strainer baskets, a water level too low for the skimmer to do its job, or a filter in need of backwashing per the maker’s instructions. Safety first: shut off the pump before you go near the strainer or skimmer basket. Wear the appropriate PPE and heed the chemical labels; never put a hand into operating suction equipment.
Time to call in a professional?
If the pump is making noise, overheating, or tripping breakers, or if you have reason to think there is a wiring issue, put in a call for qualified assistance. The same goes if filtration is not improving despite the pump running longer than usual, or if filter pressure remains off after a good cleaning. A pro can verify the equipment is safe and properly sized for the pool, and may even help lower the electricity tab. Under no circumstances should one swim in the presence of an electrical fault or unsafe water.
