Calculating Your Monthly Refrigerator Cost
To calculate how much your refrigerator costs you to run each month, you can use the following formula:
(Watts Used) x (Hours Used per Day) x (Days in Month) / 1000 x (Cost per kWh)
Step-by-Step Guide to the Calculation
Determine the Power Rating (Watts)
Check the appliance’s model number or energy guide label to find the wattage. For our example, let’s use a refrigerator with a power rating of 200 watts.Calculate Daily Usage
Refrigerators run all day, so you’ll use 24 hours a day.Calculate Monthly Usage
Multiply daily usage (24 hours) by the number of days in a month (typically 30):
24 hours/day x 30 days = 720 hours/month.Calculate Monthly Energy Consumption
Now, multiply the wattage by the total monthly hours:
200 watts x 720 hours = 144,000 watt-hours.
To convert watt-hours to kilowatt-hours:
144,000 watt-hours / 1000 = 144 kWh.Multiply by Your Local Electricity Rate
If you are charged $0.15 per kWh, your monthly cost would be:
144 kWh x $0.15 = $21.60.
So, in this example, running a 200-watt refrigerator would cost approximately $21.60 per month.
