How much will my electric bill cost when using a mini fridge?

I do not know the amount of watts for the mini fridge, but the electric company charges 8 cents per kWh... So i figured the fridge will be running 24hrs a day, for 31 days. How would I calculate the rest to find out the whole months bill, just for that mini fridge? We are trying to figure out if it would be worth to bring our mini fridges for our apartment.|||You need to know the number of watts before this can be calculated.





They come in all sizes from 500 watt to 50 watts.





I'll go through the calculation for 100 watts, substitute the number for you unit.





Most fridges run about 30-50% of the time after they have initially cooled down. I'll assume 50%





50% of 100 watts is 50 watts.


50 watts x 24 hr/day x 31day/mo = 37200 watt-hour/mo or 37 kW-hr/mo





37 kW-hr/mo x $.08/kW-hr = $2.98 per month.











PS, other answer is totally wrong, starting with the incorrect units. Appliances are not rated in kW-hrs.

I hate when people put people down for trying to help.

|||assuming its just a mini fridge, it would be about .3 or .5kwh, maybe less. So 3 cents per hr, that's $.73 a day times 31.





$22.63! If its .3kwh.





Your answer, less than $25-30 a month.
