Your refrigerator is 5.6 amps so how much does it cost you a month at 14cents per kilowatt?

$67.74 using 120 volts.

Great job on the math, but a refrigerator doesn't run 24 hours a day. It runs off of a thermostat and has periods of off/on. It depends on the climate in which you live (i.e. how hot it is in your house) as to how often your refrigerator kicks on. Its actually really hard to keep track of. If you buy a "Kill A Watt" meter, you can plug your fridge into it and it will tell you how many watts the fridge has actually used in a day. It probably only runs a few hours total each day!
