Estimated AC Electricity Bill
Upgrade to a high-efficiency 5-Star Inverter AC and save thousands on your electricity bill every year.
* Estimated monthly cost is based on your electricity rate input and the AC's annual energy consumption (divided by 12 months).
Our AC electricity bill calculator uses a straightforward formula to estimate your air conditioner's running cost. Here's how it works:
For example, if you have a 1.5 ton AC (1700W) running 8 hours daily at ₹8/unit: Daily = (1700×8×1)÷1000 = 13.6 kWh → Daily Cost = 13.6 × ₹8 = ₹108.80. Monthly (30 days) = ₹3,264.

A 1 ton AC typically consumes between 1000–1200 watts. Suitable for rooms up to 120 sq ft, these ACs are the most energy-efficient option for small bedrooms. Running a 1 ton AC for 8 hours daily consumes approximately 8–9.6 units per day.
1.5 ton ACs are the most popular choice for Indian households, consuming 1400–1700 watts. Ideal for rooms between 120–180 sq ft, running one for 8 hours daily uses approximately 11.2–13.6 units, costing around ₹90–₹110 per day at ₹8/unit.
2 ton ACs consume 1800–2500 watts and are suitable for larger rooms (180–240 sq ft) or living areas. Running a 2 ton AC for 8 hours daily uses 14.4–20 units, costing ₹115–₹160 per day.
Inverter ACs use variable-speed compressors that adjust cooling capacity based on room temperature. They consume 30–50% less electricity compared to non-inverter (fixed-speed) ACs. While inverter ACs cost more upfront, the electricity savings make them more economical in the long run, especially if you use AC for more than 6 hours daily.
Your actual AC electricity bill depends on several factors beyond just wattage and hours:

Multiply your AC wattage by hours used per day, divide by 1000 to get daily kWh (units), then multiply by your electricity rate per unit. Use our calculator above for instant results.
A 1.5 ton AC (1400–1700W) running for 8 hours consumes approximately 11.2–13.6 units (kWh) per day. Inverter models consume less.
Yes. Inverter ACs save 30–50% electricity by adjusting compressor speed. They cost more initially but pay back through lower electricity bills within 2–3 years.
24°C is recommended by BEE (Bureau of Energy Efficiency). Each degree below 24°C increases electricity consumption by approximately 3–5%.
For a 1.5 ton AC (1700W) at ₹8/unit: (1700×8)÷1000 = 13.6 units × ₹8 = ₹108.80 per day, or approximately ₹3,264 per month.
Yes. When outside temperatures are very high (above 42°C), the compressor runs continuously and takes longer to achieve the set temperature, consuming significantly more electricity.
Set temperature to 24°C, clean filters every 2 weeks, use sleep mode at night, close doors/windows, use ceiling fan with AC, choose inverter AC, and insulate your room properly.
A 1 ton AC uses 1000–1200W while a 1.5 ton uses 1400–1700W. The 1.5 ton model consumes about 30–40% more electricity but cools larger rooms more effectively.
5-star rated ACs are the most energy-efficient, consuming up to 25% less electricity than 3-star models. Always check the BEE star rating before purchasing.
Yes! This AC bill calculator works for all types — window AC, split AC, inverter AC, and non-inverter AC. Just enter the correct wattage of your specific model.
