How do you calculate the Monthly cost of using a 700 watt refrigerator that runs for 10 hours a day at a cost of 0.09 Killowatts per hour?

(700 watts) x (10 hours/day) x (30 days/month) x (1 kilowatt / 1,000 watts) =
(700 x 10 x 30 / 1,000) (watt - hour - day - kilowatt / day - month - watt) =
210 kilowatt-hour / month
We're guessing that the actual cost of your electric energy is $0.09 per kilowatt-hour.
(210 kilowatt-hour / month) x ($0.09 / kilowatt-hour) = $18.90 per month .

How many hours does a refrigerator operate in a day?
This is difficult to answer, because it depends on many factors -- how often the door is opened, the ambient temperature, how much is in the refrigerator, and whether new items were recently added to the refrigerator and need to be cooled down. Most frost-free refrigerators have a timer that runs them for 6 hours, then defrosts them for 30-35 minutes. This means, at the the upper limit a refrigerator might run 24 hours out of every 26 hours, or an equivalent of 22.1 hours per day. (The timer only runs when the compressor runs on energy saving models, so if the compressor motor doesn't run continuously, the intervals between defrost periods will be longer than 6 hours.) Once the contents are cooled down, a modern refrigerator in good condition might be expected to run 27% to 37% of the time at an ambient temperature of 70°F, i.e., 6.5 to 8.9 hours per day, and 45% to 61% of the time at an ambient temperature of 90°°F, i.e., 10.8 to 14.6 hours per day. The only practical way to determine how long a refrigerator runs each day is to connect a run-time counter to the compressor motor circuit and operate the refrigerator for one to two weeks, or longer, then read the total run time from the counter and calculate the average number of hours the refrigerator ran each day.

What if your refrigerator is 5.6 amps so how much does it cost you a month at 22 cents per kilowatt?
A refrigerator is not on all the time. It is controlled by a thermostat that keeps it at a certain temperature. To answer this question the total number of hours the refrigerator was actually running would have to be recorded. Knowing this information and the voltage at which the refrigerator operates a calculation could be made.
