AC Electricity Cost Calculator

Estimate the monthly electricity bill of your air conditioner from its power, daily hours and your tariff.

AC power (watts)

Look for the watt rating on the label. For AC, 1 ton is about 1,000–1,200 W; 1.5 ton about 1,500 W.

Hours used per day

Actually running (% of that time)

Compressors cycle on and off, so a fridge or AC does not draw full power all the time.

Days per month

Electricity rate (₹ per unit)

A unit is 1 kWh — see your bill for the rate.

Estimates only. Real use depends on the room, settings and the appliance's star rating.

A 1 ton AC draws roughly 1,000–1,200 W and a 1.5 ton about 1,500 W when the compressor runs. Inverter ACs use less on average.

The compressor switches off when the room reaches the set temperature.
