Watts Plus computes the approximate electricity cost of running electrical appliances and compares usage scenarios.

- Enter the cost per kilowatt-hour from your electricity bill, the AC voltage, and power factor.

- Enter the watts used by the appliance and the number of hours per day the appliance runs.

- Watts Plus calculates the electricity cost per hour, day, month, and year.

Enter two such usage scenarios and compare to see how much is saved by switching to an energy saving appliance. Email the comparison results.

Watts Plus saves the current data for both scenarios when the application exits. Theres no need to re-enter data that seldom changes, like voltage and power factor.
