assuming a cost of .15 per kWh and that a 10 year old fridge uses 8kWh per day, the cost per day is about $1.20.
it cost 50$
A fridge runs about half the time with out opening the door. Opening the door many times a month might add about 30 hours to the regular run time of the fridge. 30 hours of running a fridge costs about .90 dollar. If you open the fridge about 10 times a day for a month that would mean you open the fridge 90 times. so each opening of the fridge probably costs about .001 dollars. or 1/10 of a penny. Its inserting very hot items or leaving the door open for a long time while deciding what to eat that will cost more. obviously refrigerators run less in the winter unless you heat your house irregularly high and they run more in the summer. And again the price will be a bit more for each door use in the summer as the temp escaping in to the fridge when you open it is hotter.

You have to have three factors to calculate this cost. First what you are charged per Kw/hr from your power supplier, second the wattage size of the bulb that you want to do the calculation on and third the voltage of the bulb. Give me these and I can tell you how it costs to run the bulb per hour.
about 1.5 million a month
