EIA data for , updated · Source: U.S. Energy Information Administration
Running a hot tub in Iowa costs about $71.65 a month — $871.77 a year — at the state's average rate of 17.06 ¢/kWh. That's roughly $56.21 a year less than a household paying the national average pays for the exact same hot tub. The estimate assumes a typical 3,500-watt hot tub running 4 hours/day, at the all-in average rate (delivery, fixed charges, and utility fees already included; locally billed taxes vary by area).

Hot Tub cost vs U.S. average
At the state average rate, a hot tub in Iowa costs $4.62 less a month than it would at the U.S. average rate.
How much electricity does a hot tub use?
A hot tub draws roughly 1,500-6,000 W; we use 3,500 watts running 4 hours/day. That comes to 14.0 kWh a day — 420.0 kWh a month, or 5110.0 kWh over a year — using kWh = watts × hours ÷ 1000. For the wattage range, amps, and how that math works, see how many watts a hot tub uses.
Hot tubs use a heater and circulation pump that cycle to maintain water temperature. Keeping the tub heated continuously costs more than heating on demand, especially in cold climates. Iowa prices that energy at 17.06 ¢/kWh, against a 18.16 ¢/kWh national average.
Hot Tub operating cost estimate in Iowa
| Time period | Energy use | Cost |
|---|---|---|
| Per hour | 3.50 kWh | $0.60 |
| Per day | 14.0 kWh | $2.39 |
| Per month | 420.0 kWh | $71.65 |
| Per year | 5110.0 kWh | $871.77 |
These figures use the all-in average rate. Your actual bill can run higher when separately billed taxes, seasonal pricing, and fixed monthly fees apply.
What changes the cost the most?
Two things move this number: your state's rate, which you can't change, and how hard the appliance works, which you often can. For a hot tub, that mostly comes down to insulation quality, cover use, ambient temperature.

Source: U.S. Energy Information Administration (EIA) Retail Sales of Electricity. EIA data for August 2026, updated Oct 28, 2026. Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility.
