Before you buy an air conditioner, the first question that arises in your mind is how much electricity does an air conditioner consume.

The air conditioner electricity cost calculator would give you an estimate of the monthly and yearly electricity consumption of your air conditioner.

Before you go for calculation, you should know about what is a watt, kilowatt-hours, and electricity cost.

If you already know about these terms, you can skip reading and jump on straight away to the calculator.

  • Watts

‘Watts’ is the unit of power. Power in electricity is the ‘rate at which the work is done. Electronics appliances like air conditioners convert electrical energy into other forms and for that, the ratings are indicated on its nameplate in watts. Note that 1000 Watts = 1 kW.

  • Kilowatt-hour

Electrical energy is measured in kilowatt-hour. It is the work done by the appliance like the air conditioner with respect to time. 1 unit = 1 kilowatt-hour. It means that if you have a 1000 W air conditioner and it runs for 1 hour, it will consume the energy of 1 unit i.e., 1 kWh.

  • Electricity Cost

The cost of electricity depends on the tariff. Your electricity provider charges you per 1 unit (per kWh) which they usually mention in the electricity tariff. For example, if your electricity provider charges you Rs.8 per kWh then 100 units in a month would cost you Rs.800.

How to use this calculator?

To use this calculator you need to enter values.

  • First, enter the rated power in watts. The rated power of the air conditioner would be present on its nameplate.
  • Enter the hours of use in a day.
  • Enter the price that your electricity provider charges you. If you do not know, just divide your monthly electricity bill (in your currency) by 30. You would get your per unit charge.

So simple! Rest of the calculation the calculator would do.

How to interpret the calculator results?

The air conditioner can be either inverter type or non-inverter type.

In the case of non-inverter type, the compressor runs when you need cooling and switches off when a set temperature is achieved.

In the inverter type, the compressor runs at different speeds depending upon the set temperature. At different speeds, the energy consumption is also different.

So, the values you are getting is higher than the actual one.

If the Air Conditioner is having input power of 1140 Watts, daily hours of usage is 10 hours and per unit charge is Rs.8 then the monthly electricity cost of this air conditioner would be Rs.2736
