How much electricity does a hot tub use?
In U.S. homes that have one, a hot tub uses about 1,963 kWh a year, or 164 kWh a month. At the 2025 average residential price of 17.2¢ per kWh that is $338 a year or $28.19 a month. These are EIA estimates from its Residential Energy Consumption Survey of homes and their utility bills, not a manufacturer's label.
What decides the number
Homes with a hot tub used 1,479 kWh a year to heat it and 484 kWh for the pumps, 1,963 kWh together. Keeping the water hot is the main cost, so a tight cover and a lower temperature when it is not in use matter most.
