Running a sauna at home is actually more affordable than most people expect. This calculator helps you estimate your electricity cost per session, per month, and per year based on your usage and local electricity rates.

Simply adjust your sauna size, session length, and frequency to see your projected running costs instantly.

Your results are based on:

• The average power draw of your selected sauna size (in kilowatts)
• Your session length in minutes
• Your electricity rate (AUD per kWh)
• Your weekly usage frequency
  

The formula used is:

Power (kW) × Hours Used × Electricity Rate

Results are estimates and may vary depending on insulation, ambient temperature, and real-world heating cycles.

Also, read our full guide on energy costs if you plan to do the calculations yourself.

For most households, daily 15 to 30-minute sauna sessions typically add only a small amount to your overall electricity usage — often comparable to running:

• A small space heater
• A clothes dryer for a short cycle
• A dishwasher load
  

Infrared saunas are generally more energy-efficient than traditional steam saunas because they heat the body directly rather than heating large volumes of air.
