AC electricity consumption calculator
How many units and rupees your AC (or any appliance) uses per month.
How it's calculated
kWh = watts × hours/day × days × quantity ÷ 1000. Cost = kWh × rate.
- Inverter ACs draw less than rated power once the room is cool — use measured/average watts if known

Questions
Where do I find the wattage?
Check the rating plate or manual for input power in watts. For inverter ACs the average draw after the room cools is often well below the rated maximum.
Does a higher thermostat setting save power?
Generally yes — each degree warmer reduces the compressor's work. Measure with a plug-in energy meter for the most accurate wattage.
