About the Appliance Electricity Cost Calculator
Every appliance's running cost depends on its power in watts and how long it runs. A 1.5-ton AC running 8 hours a day uses about 240 units a month, far more than all your fans and lights together, while a geyser uses a lot of power for a short time.
Choose up to six appliances, the hours each runs and how many you have. The calculator uses typical wattages (change them if you know the label value), multiplies by your tariff, and shows the units and cost per day, month and year, with a chart of what costs most.
