Running cost calculator, US

Energy used = power in kW × hours × share of time the heater or chiller is actually on. Cost = energy × your electricity price.

EIA 2025, retrieved November 13, 2026. 19 of 191 US sauna listings state their power.

For a hot tub or chiller that stays on, choose 24 hours and 7 days.
How hard the device works
% of the time at full power Our assumption: the heater runs at full power for the first 45 minutes, then the thermostat keeps it at about half. Always at full power is the upper limit. Type your own percentage if the manual states one.

How this is calculated

Energy per use8 kW × 1.5 hours × 75% at full power9.0 kWh
Cost per use9.0 kWh × 17.23 cents per kWh$1.55
Energy per year9.0 kWh × 3 a week × 52 weeks1,404 kWh
Cost per year1,404 kWh × 17.23 cents per kWh$241.91

Typical use is our assumption, not a measurement; no independent study exists, so the upper limit is shown next to it. Electricity only. Standing charges, water, chemicals, wood, installation and maintenance are not included.

One hour of sauna by state

Cost of one hour at 8 kW, the median power of 19 US sauna listings that state it, with the heater on the whole time, at each state's 2025 average residential price. The list is sorted cheapest first.
