How to use

Enter the wattage (pre-filled to about 150 W, the typical draw for a Refrigerator), set how many hours per day it runs, and add your electricity rate. WattCost multiplies watts ÷ 1000 × hours × days to get kWh, then multiplies by your rate for the cost.

Keep it at 35–38°F (1.7–3.3°C); one degree colder can add about 5% to the running cost.
