8 Best Free Online AC Electricity Bill Calculator Websites

Here is a list of the best free online AC electricity bill calculator websites. Air Conditioners require lots of power and thus consume a significant amount of electricity to operate. Running an AC for several hours a day can spike your electricity bill. So it would be wiser to estimate the operating cost of an AC to know how much it would cost you on the electricity bill.

With the help of an AC electricity bill calculator, you can estimate the operating cost of an Air Conditioner. To do that, you just have to provide the power consumption of the AC. Generally, the power consumption of an AC is measured in Ton. Mathematically, you can directly convert Tons into kilowatts. But in the case of AC, it gets a little complex. You have to consider the Energy Efficiency Ratio (EER) and cooling capacity in the calculation.

The power consumption of an AC is equal to cooling capacity divided by EER. For a 3-star AC, the EER is 2.7. If it has a 1-ton cooling capacity (which is equal to 3.517 kW) then the power consumption would be 1.5*3.517/2.7=1.954 kW. Using this formula, you can calculate the power consumption of the AC. Then you can simply add that value to any of these AC Electricity Bill Calculators along with the daily hours of use. This way, you can estimate how much you would have to pay to use the AC.
