5 key variables that change your ₹/hour figure
Electricity Rate (₹/unit)
₹7/unit vs ₹10/unitYour state electricity tariff has the biggest single impact. Bihar pays ₹7/unit; Mumbai pays ₹12+/unit. This alone swings hourly cost by ₹3–₈.
AC Tonnage
1 ton vs 2 tonA 2-ton AC uses roughly 60–80% more electricity per hour than a 1-ton. Over-tonnage wastes power — always size correctly for your room.
BEE Star Rating
3-star vs 5-starA 5-star AC uses 20–25% fewer units per hour than a 3-star model. On 8 hours/day, that's ₹600–₹900 saved every single month.
Temperature Setting
18°C vs 24°CEvery 1°C lower than 24°C increases power consumption by 6%. Running at 18°C costs 35–40% more per hour than 24°C. Simple, huge impact.
Inverter vs Non-Inverter
Save ₹4–₈/hourInverter ACs modulate compressor speed and avoid constant on/off cycling — saving 25–40% electricity vs fixed-speed non-inverter units.
