5-Star vs 3-Star AC — Which Saves More Over 5 Years?

A 1.5-ton 5-star AC typically costs ₹8,000–12,000 more upfront than a 3-star model. That price gap scares most buyers into picking the cheaper option. But here's what the showroom doesn't tell you.

A 3-star inverter AC consumes around 1.05 kWh/hour. A 5-star inverter AC of the same tonnage consumes around 0.85 kWh/hour. Run both for 8 hours/day for 6 months a year at ₹8/unit: 3-star → ₹12,096/year. 5-star → ₹9,792/year. Difference: ₹2,304/year.

Over 5 years, you save ₹11,520 on electricity with the 5-star — more than the upfront price difference. Over 10 years (typical AC life), you save ₹23,040. The 5-star is the cheaper AC in the long run, every single time.

Add the SaveMyBill saving on top of that and you stretch your money even further. When buying any major appliance — AC, fridge, washing machine — always pick the highest star rating you can afford. The math always favours efficiency.
