Operating cost calculator

Turn heater kW into dollars per session.

A transparent scenario calculator for electric traditional saunas. Change every assumption yourself.

What the calculator assumes

Warm-up is modeled at full heater output. During the session, the estimator uses a 60% full-load-equivalent duty assumption rather than assuming the heater runs continuously at maximum output.

Actual thermostat cycling, outdoor temperature, insulation, glass area, ventilation, door openings and user behavior can materially change consumption.
