Updated July 2026 rate dataLiving & Major LoadsSourced from U.S. EIA — Electricity use in homes (end-use shares)
Evaporation is what the heater is really fighting, so a well-fitting, latched cover and a lower standby temperature between soak days do more for your bill than anything else you can adjust. Set your daily energy use and state below.
EIA residential average, July 2026. Your utility's exact rate is on your bill.
Real-time math: 1,500 W × your state's rate, accumulating live. This live meter shows continuous draw at the selected wattage; it is not the tub's average daily-use estimate.
Run like this for a year and it adds about $401 to your electricity bill.
These are planning estimates; measure or check your tub and pump's manufacturer data for exact energy use. Rates use the EIA residential average.
Energy: 6 kWh per day · 2,190 kWh per year, at 18.31¢/kWh (U.S. average).
Evaporation carries heat away fast. A good-fitting, latched foam cover reduces heat loss and can lower heater runtime. Covers also age; inspect yours for damage and follow the manufacturer's replacement guidance.
Holding 104°F around the clock is the expensive default. Dropping standby to 98–100°F between soak days saves meaningfully; an on-demand strategy (heating before use) saves most for occasional users with cheap overnight rates.
The same tub costs roughly half as much in summer as in a freezing February. Wind exposure and an insulated cabinet close the gap.
Jet sessions run the pump(s), adding electricity use. The amount depends on pump power and run time; use the label or manufacturer data where available and include that load in your estimate.
Biggest savings first.
Typically $20–60/month at the U.S. average rate (18.31¢/kWh) for a kept-warm family tub: roughly 3–12 kWh/day. Well-insulated tubs in mild climates can stay under $20; a big tub in a cold state without cover discipline can pass $100.
Around 3–12 kWh/day for a maintained family tub — the heater's duty cycle does almost all of it. That's like running a dishwasher 2–8 times daily, every day.
For regular users (3+ soaks a week), holding temperature usually wins — reheating from cold takes a lot of energy too. For weekend-only users, dropping standby temperature a few degrees is the middle path; full cold restarts are for long absidences.
In a cold climate, expect the winter peak month to run 1.5–2× the summer figure — often $50–120/month at the U.S. average rate depending on size, insulation and cover use. Check the state-rate selector above: the same tub in Massachusetts costs about 2× the Nevada figure.
