This calculator calculates the cost of electricity in running electrical appliances and equipment.
The required values are as given in the table. The power rating (watts) is usually given in the
back label of appliances. The energy rate (cents/kw-hr) can be found in the electricity bill. This
calculator is useful for estimating energy cost and also for making sense of your electricity bill.
There are also gadgets out there that can be attached to your electrical appliance and give you a
running total of usage time. Please use the "Add Rows" button to enter more appliances into the table.
To insert rows to the top of topmost row, first select the topmost row. Then click on the "Insert Rows" button.
This adds a blank row below the topmost row. Next, select the two topmost rows and click on the "Interchange Two Rows" button. More
blank rows can be added to the top by selecting the top blank row and clicking on the "Insert Rows" button.
