Homes with swimming pools use 40-50% more electricity than homes without one. The amount of additional usage varies based on the type and size of pool pump and how long it runs.
A standard 2000 watt pool pump will use around 480 kWh a month. An equivalent variable speed 300 watt pool pump will use around 72 kWh a month. That’s a huge difference in electricity usage.
How Much Electricity Does a Pool Use?
The amount of electricity your pool pump uses depends on three things: (1) the type of pool pump (2) the number of pool pump watts and (3) how long the pool pump runs each day.
How much electricity does a standard pool pump use?
A standard pool pump uses between 1500 and 2500 Watts of energy. And it typically runs a minimum of 8 hours a day to circulate and clean water. Assuming a 2000 Watt (approximately 2.5 horsepower) motor running 8 hours a day you will use 480 kWh a month. Here’s the math.
Appliance: Standard Pool Pump (single speed)
Number of Watts: 2000 watts
Hours used per day: 8 hours
2000 watts X 8 hours = 16,000 watt-hours per day
16000 watt-hours per day / 1000 = 16 kWh per day
16 kWh per day * 30 days in a month = 480 kWh per month
How much electricity does a variable speed pool pump use?
You’ll want to switch to a pool pump that gives you water circulation at the lowest wattage level and shortest run time. A variable speed pump uses around 300 watts. Assuming it runs for 8 hours a day, you’ll use just 72 kWh per month with a variable speed pool pump.
Appliance: Variable Speed Pool Pump
Number of Watts: 300 watts
Hours used per day: 8 hours
300 watts X 8 hours = 2,400 watt-hours per day
2,400 watt-hours per day / 1000 = 2.4 kWh per day
2.4 kWh per day * 30 days in a month = 72 kWh per month
How much electricity does a variable speed pool pump save?
Changing from a 2000 watt standard pool pump to 300 watt variable speed pool pump can cut your pool’s electricity usage by 80%. And you can cut your usage even more from there, with some small operating adjustments that we discuss below.
TIP: The folks at Energy.gov recommend reducing your pool filtration time to 6 hours a day versus the standard 8 hours. If the water appears cloudy, bump up your filtration time in 1/2 hour increments until you get it right.
How Variable Speed Pool Pumps Lower Your Electricity Bill
The benefits of variable speed pool pumps include increased energy efficiency, lower electricity bills, and quieter operation. They also tend to last longer than standard pumps, around 12-15 years according to one source, so you’ll save money in the long run as well.
There are three ways a variable speed pool pump lowers your electricity bill.
First, variable speed pumps operate at a lower speed most of the time, which uses less energy. They can ramp up to a higher speed when necessary, such as when you need to backwash your filter or run your pool cleaner.
Second, variable speed pumps use a smaller amount of energy (watts) to maintain the desired flow rate. This means that variable speed pumps are much more efficient than traditional pumps, which often use more energy than necessary.
Third, variable speed pumps usually have multiple programmable speeds and a built in timer. This lets you customize your pool pump’s run time, speed of circulation and the time of day when you run it.
This is especially important if you have a free nights electricity plan or an electricity plan for pool owners, like OhmConnect PoolConnect electricity plan. You can schedule your pool filtration when electricity is free or discounted.

How to Switch from Standard to Variable Speed Pool Pump
The process of switching your pool pump from a standard pool pump to a variable speed pool pump is not a DIY project (unless you have electrical experience). It requires finding a pool professional.
According to Homeadvisor, it will cost between $700 to $1500 to install a new variable speed pool pump. That’s in addition to the cost itself, which ranges from $750 to $2000.
The installer will not only install the new pump, they’ll also calibrate the new pool pump to circulate water at the lowest speed possible. That will help ensure your pool pump operates efficiently.
