How Much Does It Cost to Run a Whirlpool Tub?
The jet pump draws about 1,000 watts, but the real cost of a soak is the 40+ gallons of hot water from your water heater. At the US-average rate of 16.5¢/kWh, running a whirlpool tub costs about $1.50/month ($18.05/year) at typical use. Adjust the watts, hours, and your rate below for your exact number.

Cost = power (kW) × hours × days × your rate. Defaults are typical values — enter your appliance's actual watts (often on a label) and your real rate for a precise figure.
How much electricity does a whirlpool tub use?
At 1,000 W for 0.3 hours a day, a whirlpool tub uses about 0.3 kWh per day — roughly 9 kWh per month and 110 kWh per year. That's about 1% of the 863 kWh the average US home uses in a month. Energy use is the same everywhere — only the price per kWh changes your bill.

Measure what a whirlpool tub really costs you
The estimate above uses typical wattage and hours. This load is usually hardwired or on a 240 V circuit, so a plug-in meter won't fit it; a whole-home monitor's sensors clip onto the circuit's wires inside the panel and log its real kilowatt-hours. That means working in a live panel — hire an electrician if that isn't you.
