How Much Electricity Does a Hot Tub Use Per Month?

Many new spa owners wonder what their monthly electric bill will look like after installing a hot tub. It’s a fair question, and the good news is that most modern hot tubs are far more efficient than people expect. With the right setup and maintenance habits, the monthly cost stays surprisingly manageable.

What Affects Hot Tub Energy Use?

Several factors influence how much power your spa uses, and they can vary from home to home. A few of the biggest things that affect energy consumption include:

  • Hot tub size (more water = more heating)

  • Insulation quality

  • How often you use the spa

  • Water temperature settings

  • Local climate and seasonal temperatures

  • Age and efficiency of the heater and pump

Small changes in one or two of these areas can make a noticeable difference in your bill.

Typical Monthly Electricity Cost

Most mid-sized 4–6 person spas use between 1,500 and 6,000 watts when the heater and jets run. Day-to-day usage isn’t constant, though; your tub cycles on and off to maintain the set temperature.

For most households, monthly electricity costs fall in the range of:

  • $20 to $60 per month for typical use

  • $80 to $100 per month in colder climates or heavy use (for example, daily soaking or long jet cycles)

If you live in a warm region, keep moderate water temps, and maintain your spa well, you’ll usually sit on the lower end of that range.

Ways to Reduce Your Hot Tub’s Power Usage

If you want to keep your electricity bill as low as possible, a few small adjustments can make a big impact. Consider trying:

  • Lowering the temperature a few degrees when not in use

  • Using a well-insulated cover and checking it for heat loss

  • Running filtration cycles during off-peak electricity hours

  • Keeping the water balanced, which reduces strain on the heater

  • Upgrading to a more efficient pump or heater if your spa is older

Sometimes, even something simple, like reducing jet time or controlling how often the lid is opened, helps maintain more stable heat and saves money.
