Just like food, we wouldn’t want to waste
Cost of food is on the rise so does the cost of electricity
So considering the food cost, it should include everything that is necessary to maintain and keep the food fresh as you are consuming it.
Calculating energy cost of fridge or appliances
As a general rule of thumb (not include other variables: usage, equipment operating condition, environment and etc.), to calculate amount of power usage for an appliance as well as other electrical equipment do the following formula:
Watt* x Operating Hours Per Day (based on 24/day) = Watt-Hours per day
Watt-Hours/1000 = kWh per day
kWh per day x cost per watt = energy cost per day
energy cost per day x days of month (usually 30 or 31) = total energy cost per month
*Note: if you do not have watt information, use Amps x Volts = Watts
Compare to your monthly electric
Take the above figure and it should give you a rough estimate about how much your fridge or appliance would be using, remember this does not include usage and other factors.
