How Much Power Does a Hot Tub Use 2024?


Having a hot tub on your property can make access to the life of luxury much easier, but you might want to ask yourself, “how much electric does a hot tub use?” A hot tub typically uses an average of 2,514 kilowatt-hours of energy per year. The energy consumption of a hot tub primarily goes into heating and circulating the water, with a small amount used for lighting. The specific power usage of a hot tub can vary depending on factors such as the size, model, age, and features of the hot tub.

Shockingly, while hot tubs use a lot less energy than they used to in the past, you can still expect your hot tub energy cost to be higher than you might think! Many popular manufacturers claim their hot tub electrical cost is only about $1 a day to run, which can be much higher or lower depending on the hot tub variety.

Hot Tub kWh Usage

When you decide to install a hot tub at your home, you might be wondering exactly how your hot tub electricity usage works. The most energy your hot tub uses is from the heater, which makes sense due to how hot the temperature of the water is in your jacuzzi. Between the varieties of heaters, we see hot tub energy consumption kWh between 1.5 kWh – 6 kWh (1500 watts – 6000 watts).

The average television consumes about 1 kWh of energy at about 1 hour of consumption a day for comparison.

Do hot tubs use a lot of energy?

If you use your hot tub every single day, or frequently, your hot tub energy use would be very high and cost you quite a bit. While that question can be subjective, you can expect there to be a rather large increase on your monthly electricity bill if you are running your hot tub every day. Even at the lowest wattage, you’re still adding about $30 to your electricity bill a month to maintain your hot tub.

How Much Electricity Does a Hot Tub Tub Use Per Month 2024?

If you are looking into purchasing a hot tub, you will want to be aware of the hot tub electrical cost per month. It is completely normal to ask yourself, how much electric does a hot tub use a month when looking into making a new investment in a jacuzzi. As we learned in the previous section, just a 120-volt or 240-volt heater can pull between 1,500 watts to 6,000 watts of energy depending on the time of year. To compensate for any other necessary parts like pumps, lights or accessories, let’s assume another 1500 watts of hot tub electricity usage.

We also have to remember that just the electricity used to maintain the water temperature of your jacuzzi will be the lowest possible hot tub cost. When you are actively using your hot tub, the water pump will be running continuously, which means a higher energy bill.

How much does it cost to run a hot tub every month?

Now that we have our basic information, let’s figure out the electric cost for hot tub per month. For this equation, you will need to know the kWh rate your utility company charges (we will use the national average) the wattage of your heater, and how many hours you use it. We always say that a good rule of thumb is to budget between $20 – $40 a month to maintain and pay for your hot tub electric usage.

Here is a hypothetical hot tub electricity cost calculator with some common numbers you might see when using a small hot tub at your home.

  • Small 120-volt heater – 2000 watts or 2 kWh
  • Water pump – 1,500 watts or 1.5 kWh
  • Average cost of kWh on electric bill – 14.77 cents
  • Time spent in the hot tub

Add together the kWh for the accessories needed which comes out to be 3.5 kWh of energy per hour usage of your hot tub. On average, let’s estimate that a family might need to run a hot tub for 50 hours a month. To calculate jacuzzi electricity consumption, multiply 3.5 kWh by 50 to get 175 kWh of energy usage per month.

To then get the total hot tub cost, take 175 kWh and multiply that by the rate provided by your utility company, which we are using the national average, $14.77

The average cost to run your hot tub per month is about $26 with our equation, which can be much more or less depending on what you’re running. If your hot tub runs a 240-volt heater, running at 7.5 kWh, expect your jacuzzi electricity consumption to be just about double costing you about $50 per month.

How much electricity does a hot tub use per year?

By using our equation above, you can take how does a hot tub cost to run per month and multiply it by 12 to get your estimated yearly cost. With that being said, how much does a hot tub cost electricity per year? Our estimate shows that the average hot tub with a small heater could cost up to $310 a year.

Obviously, as we have been stating, your hot tub running cost could be much higher or lower depending on a variety of factors.

How much to run a hot tub in the winter?

Running a hot tub in the winter can help cure all of your chills especially when you sink into a bubbling hot jacuzzi with a view. Your hot tub winter cost can be exponential if your starting water temperature is below 60 degrees. It can take up to an extra 40 kWh to heat a hot tub from 50℉ to 100℉, and even more if your water is colder.

Even if you only use your hot tub a handful of times in the winter, heating it in colder temperatures can make your hot tub electricity usage cost you about $5 per use!

What Other Costs Come with Hot Tub Energy Usage?


As we mentioned above, your hot tub electricity cost can significantly vary depending on the different factors that come with your hot tub. We think when trying to calculate how much a hot tub costs in electricity it is important to outline all of the factors that can increase your electric bill.

Factors that affect cost of running a hot tub:

  • Outdoor climate and temperature (air temp and wind speed)
  • Size of hot tub
  • Quality and age of hot tub
  • Type and fit of hot tub cover
  • Hot tub thermostat setting
  • Age and quality of water heater

Each of these factors will have a major role in calculating how much it will cost to run your hot tub for any amount of time. One of the largest factors in hot tub energy cost is the size and how much water your tub holds. Remember, the more water in your tub, the more overall energy you use to heat it. It is also super important to keep on on maintenance and cleaning of your hot tub. Poorly maintained parts can contribute to high hot tub electricity costs due to not working at their fullest potential and sucking energy.

How much does it cost to clean a hot tub?

As we mentioned, maintenance is a huge part of keeping a clean and efficient hot tub to make sure that you aren’t wasting any money due to faulty parts. The best way to reduce your hot tub energy usage is to keep up with all required cleanings and other required upkeep that comes with owning a jacuzzi. Many new hot tub owners do not consider that you have to drain and replace the water at least once a year, which requires an addition of chemicals to keep your water clean.

It is smart to budget an extra $100 a year, just in case, to preserve the quality of a brand-new hot tub. That includes any extra lighting that you might need to purchase, as well as, part replacement as necessary.
