How to Calculate AC Electricity Cost
Use this simple formula to estimate how much your AC costs to run. All you need is your AC type, daily usage hours, and local electricity rate.
The Formula
Units
Kilowatt-hours consumed per hour of AC use. Depends on tonnage and star rating.
Hours
How many hours per day you run the AC. Multiply by 30 for monthly usage.
Rate
Electricity rate per unit (kWh) in your city. Typically ₹6–₹12 in India.
Step-by-Step Calculation Examples
1.5 Ton Inverter AC
1 Ton Non-Inverter AC
2 Ton Inverter AC
Pro tip: Actual costs vary based on room size, ambient temperature, insulation quality, and thermostat setting. Inverter ACs use 30–40% less power than non-inverter models because they adjust compressor speed instead of full on/off cycles.

How to Reduce AC Electricity Cost
Follow these proven strategies to cut your monthly AC bill by 30–50% without replacing your unit.
Choose Inverter AC
Inverter ACs consume 30–40% less electricity than non-inverter models. They adjust compressor speed instead of cycling on and off, saving ₹500–₹1,500 per month.
Best Inverter ACs →Set Temperature to 24°C
Every 1°C below 24°C increases power consumption by 6–8%. Setting your AC to 24°C instead of 18°C can save ₹300–₹600 per month without sacrificing comfort.
More Bill Saving Tips →Pick the Right Size
An oversized AC wastes energy through short cycling. An undersized one runs constantly. Match tonnage to room size: 1 ton for up to 120 sq ft, 1.5 ton for 120–180 sq ft.
Room Size Calculator →Buy 5-Star Rated AC
A 5-star AC uses 15–25% less power than a 3-star model. Over 5 years, the electricity savings often exceed the price difference between star ratings.
Best 5-Star ACs →Seal Doors and Windows
Cool air escaping through gaps makes your AC work harder. Use door stoppers, weather strips, and curtains to maintain room temperature and reduce compressor load.
Clean Filters Monthly
Dirty filters block airflow and force the compressor to work 15–20% harder. Cleaning filters every 2–4 weeks keeps efficiency high and electricity consumption low.
AC electricity cost depends mainly on tonnage, usage hours, and local electricity rate. A typical 1.5 ton AC costs ₹8–₹12 per hour in India.
Choosing an inverter AC, setting the thermostat to 24°C, and selecting the correct tonnage for your room size are the most effective ways to reduce monthly bills.
“A 1.5 ton AC costs around ₹8 to ₹12 per hour in India, while a 1 ton AC costs ₹6 to ₹10 per hour. Inverter models cost 30 to 40 percent less than non-inverter ACs.”
