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 that you’re running your pool? Let’s look at the average monthly costs for running swimming pools and the factors contributing to your monthly bill.

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 electricity rates in your region. Some places will have higher rates than others. If you’re concerned that your monthly bill is too high, take a 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 for 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 is running all day, it will use a lot of electricity every day. 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 we mentioned above, the type of pump you’re using can impact how much you are paying on 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 are using 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 the task they are performing, 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 if you’re looking to cut costs, a lower water temperature might be an excellent place to start.

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.

Wrapping Up

While many factors determine the cost of running a pool, that doesn’t mean that 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 out for on your next bill, you’ll be in a great place to make changes if you need to.
