Monthly Electrical Costs to Run a Swimming Pool

Having a swimming pool in your backyard can feel like a luxury, but it can be costly to run and maintain. Have you ever felt like you’re paying way too much on your monthly electricity bill in the months you’re running your pool? Let’s look at the average monthly costs of running swimming pools and the factors contributing to your monthly bill.

Main Takeaways

  • Some factors that determine your monthly electrical costs include: location, the pump you use, the size of your pool, and how long the pump runs.
  • The average cost to run a variable speed pump is $10.41 a month.
  • The average cost to run a single speed pump is $37.50 a month.
  • The median monthly cost to run a pool heater is $100-300, but it can drop down to $25-100 if you use it alongside a pool cover.

What Factors Determine Your Monthly Electrical Costs?

Like an electrical bill, many factors make up the final cost of your pool’s electrical bill. These factors and other pool maintenance tips are below.


A significant factor in your monthly electric bill is the area you live in and the electricity rates in your region. Some places will have higher rates than others. If you’re concerned that your monthly bill is too high, look at the standard electricity rates in your area. The weather will also play a significant factor. If you live in a colder climate, you may be spending more on your pool heater costs.

What Pump You’re Using

The type of pool pump you are using can also impact your monthly bill. Some pumps are built to be more efficient, while others will use more power. For a breakdown of the estimated cost of running some of the more common pumps, continue reading.

Size of Your Pool

The size of your pool can also contribute to your monthly electric bill in some cases. If your pool has a heater or heat pump, the amount of work it needs to do to heat a larger pool versus heating a smaller pool is significant.

How Long Your Pump is Running

Another factor is the amount of work your pump is doing. If your pump runs all day, it will use a lot of electricity daily. If you have a heater for your pool, consider only having it turned on when the pool is used to save electricity. If your pool catches much debris from nearby trees, putting a cover over the pool may help offset the amount of work your pump needs to do when it isn’t being used.

Estimated Electrical Costs for Your Pool

As I mentioned above, the type of pump you’re using can impact how much you are paying for your electric bills. Here’s a look at the estimated cost of running the three most common pump types.

Variable Speed Pumps

Variable speed pumps are the most energy-efficient of the leading pump options as they can regulate and adjust the amount of power they use based on their task. If your pool pump is Energy Star rated, the average expected annual cost for running a variable speed pump is around $125, or roughly $10.41 per month, making it the most affordable option to run year-round.

Single Speed Pumps

Single-speed pumps tend to use more energy than variable speed pumps, as they cannot regulate their energy use in the same way that variable speed pumps can. The single-speed pumps run at their maximum speed regardless of their task, thus wasting energy and costing you more per month.

The average expected annual cost for running a single-speed pump is around $450, or $37.50 per month.

Heaters/Heat Pumps

The cost of using a heat pump for your pool depends on two things: the size of your collection and the temperature you are heating your pool to. Larger-sized pools and high temperatures will use more electricity than heating a smaller pool or choosing a lower temperature.

Your pool’s temperature is obviously up to personal preference, but a lower water temperature might be an excellent place to start if you’re looking to cut costs.

Use this pool heater size calculator to break down the annual cost of running a heat pump in different regions and different temperature zones. Depending on your area and the expected period of use (summer versus year-round), the median monthly price point for the heat pump system is between $100-300.

We also want to point out – there is a significant drop in the cost of running a heat pump if you use a pool cover. Adding a pool cover can bring the average price down to $25-100 per month. Check out my top rated pool covers for specific recommendations.

Wrapping Up

While many factors determine the cost of running a pool, that doesn’t mean it has to be costly. If you’re looking to lower the impact of running a pool on your electricity bill, you may want to consider changing your pumping system to one that is more energy-efficient. Now that you know what to look for on your next bill, you’ll be in a great place to make changes if necessary.
