Hi.
It is difficult to provide you with a straight answer as there are
several variables to consider:

1. The current ambient
temperature

2. The temperature you
set the Dynamic Infrared Sauna to

3. The number of actual
heating watts on the Dynamic Infrared Sauna (varies by model)

4. Your utility rate per
kWh

5. The heat is not
continuously generated and turns on and off according to the thermostat

Formula: wattage x hours used ÷ 1000 x price per
kWh = cost of electricity

Our Dynamic Infrared
Saunas are very cost efficient and cost effective. In general and if you use the sauna for an
hour for 5 days out of the week for about 1 hour per day, you would probably
see a $10 to $15 increase (varies by sauna model and utility rates in your
area). We hope this information is helpful. Thank you for your inquiry.
