Air Cooler Electricity Cost Calculator
Find out exactly what your air cooler costs per day, per month and for a full 4-month summer season — and see how much you save compared to a 1-ton inverter AC.
| Metric | Your air cooler | 1-ton inverter AC* |
|---|---|---|
| Power | — | 1100 W |
| Units per day | — | — |
| Cost per day | — | — |
| Cost per month | — | — |
*Assumes 1100 W for a 1-ton inverter AC, at the same daily hours and tariff you entered above.
How it is calculated
Kilowatts = watts ÷ 1000. Units per day = kilowatts × hours. Cost = units × your tariff. Monthly values multiply the daily result by the number of days, and the season cost multiplies the monthly result by 4.
Frequently Asked Questions (FAQ)
How much electricity does an air cooler use?
Air coolers usually use 120 to 250 watts. The calculator includes preset buttons of 120, 150, 200 and 250 watts plus a custom field, so you can match your exact cooler model.
How is the air cooler running cost calculated?
Cost equals wattage divided by 1000 to get kilowatts, times hours used per day, times your tariff per unit. A 200 watt cooler running 10 hours a day uses 2 units daily.
What is the season cost?
The season cost multiplies the monthly result by 4, which covers a typical 4-month hot season of cooler use.
How does an air cooler compare to a 1-ton inverter AC?
The comparison row uses an assumed 1-ton inverter AC load of 1100 watts at the same hours and tariff. Air coolers usually cost far less to run because they use about 5 times less power.
