SaunaCost, the calculator for the price of getting sweaty
A focused calculator for estimating home sauna electricity use, session costs, monthly bills, yearly totals, and optional purchase amortization.
Field notes
The calculator bases its estimate on nameplate wattage rather than a brand database, then converts session minutes and weekly frequency into energy and dollar totals. Users can switch between infrared cabin presets and higher-powered traditional-heater assumptions, enter a bill-specific rate, and include heat-up time at full power. An optional amortization mode spreads a purchase price across ownership years or a stated lifetime session count. The page identifies its figures as unofficial planning math and says the example uses 1,800 watts for 30 minutes.
