AC Electricity Cost Calculator for 1 Ton, 1.5 Ton & 2 Ton AC in India [2025] As summer temperatures continue to rise, air conditioners (ACs) have become essential in almost every Indian household. But most people don’t know how much electricity their AC is consuming—and what it costs every day, month, or year.
This blog will help you calculate electricity bills for 1 Ton, 1.5 Ton, and 2 Ton ACs in India, using real examples and a free AC power consumption calculator. Let’s break it down in a simple and easy-to-understand way.
🔧 What Does “1 Ton”, “1.5 Ton”, or “2 Ton” Mean in AC?
In air conditioners, “Ton” doesn’t refer to weight. It measures cooling capacity.
- 1 Ton AC = Can remove 12,000 BTU/hour of heat
- 1.5 Ton AC = 18,000 BTU/hour
- 2 Ton AC = 24,000 BTU/hour
Generally, more tons = more power consumption.
⚡ Wattage of Different AC Capacities
| AC Capacity | Power Consumption (Approx.) |
|---|---|
| 1 Ton | 1000 – 1300 Watts |
| 1.5 Ton | 1500 – 1800 Watts |
| 2 Ton | 2000 – 2500 Watts |
Power use can vary based on AC type (Window/Split/Inverter) and energy rating.
🧮 AC Electricity Cost Calculator Formula
To manually calculate:
Electricity Units (kWh) = (Wattage × Hours used) ÷ 1000
Cost = Units × Electricity Tariff (₹ per unit)
🖩 Sample Electricity Cost Calculations
📌 1 Ton AC (1200W), 8 hours/day, ₹8/unit
- Daily: (1200 × 8)/1000 = 9.6 kWh → ₹76.80
- Monthly: 9.6 × 30 = 288 kWh → ₹2,304
- Yearly: 288 × 12 = 3456 kWh → ₹27,648
📌 1.5 Ton AC (1650W), 8 hours/day, ₹8/unit
- Daily: (1650 × 8)/1000 = 13.2 kWh → ₹105.60
- Monthly: 13.2 × 30 = 396 kWh → ₹3,168
- Yearly: 396 × 12 = 4,752 kWh → ₹38,016
📌 2 Ton AC (2250W), 8 hours/day, ₹8/unit
- Daily: (2250 × 8)/1000 = 18 kWh → ₹144
- Monthly: 18 × 30 = 540 kWh → ₹4,320
- Yearly: 540 × 12 = 6480 kWh → ₹51,840
