What this means for your AC: a 1.5-ton 5-star inverter AC draws roughly 0.9 kW on average. Running it about 7 hours a day adds ~189 units a month. In Bangalore, those extra units mostly fall in the ₹5.80/unit band, so the AC adds roughly ₹1,096 in energy charges per month — before duty and surcharge.

Three things decide your monthly AC bill in Bangalore: the local tariff (you pay ₹7.2/unit on the slab shown above), the efficiency of the unit (a 5-star inverter draws far less than an older 3-star of the same size), and your usage — with tropical savanna conditions, households here run their AC around 7 hours a day through the peak months, and every extra hour adds directly to the bill.
The biggest lever most people miss is right-sizing: an undersized AC runs flat-out and never quite cools, while an oversized one short-cycles and wastes power. Match the tonnage to your room with the tonnage calculator, then pick the star rating that pays back for your hours using the BEE star rating guide. Set the thermostat near 24–26°C rather than the lowest setting, keep filters clean, and shade the outdoor unit — each meaningfully cuts consumption.
To see exactly what your own setup costs in Bangalore, run your tonnage, star rating, and daily hours through the Bangalore AC bill calculator — it applies the Karnataka rate so the estimate reflects what you actually pay.
