3. AC Electricity Bill Calculator (1.5 Ton, 1 Ton, 3-Star & 5-Star)
Air conditioners are the single largest contributor to residential summer power bills in India. Using an ac electricity bill calculator (specifically an ac 1.5 ton electricity bill calculator) helps you understand estimated running costs before buying or using your AC.
4. Components of Electricity Bills in India
Your monthly electric bill consists of five primary components:
- Energy Charges (Slab Sum): Units consumed multiplied by respective slab rates (kWh × ₹/unit).
- Fixed / Demand Charges: Monthly fee per kW of sanctioned load (kW × ₹/kW/month).
- Fuel Adjustment Charge (FAC / FPPPA): Variable surcharge based on coal/fuel cost variations.
- Electricity Duty: State tax percentage (ranging from 4% in Odisha to 21% in Maharashtra).
- Meter Rent: Nominal monthly rental for the energy meter (₹10 to ₹50/month).
5. Frequently Asked Questions (FAQ) - Electricity Bill & Appliance Consumption
Q1. How to calculate electricity bill calculator
To calculate your electricity bill using an online calculator, select your state or electricity distribution company (e.g. TNEB Tamil Nadu, KSEB Kerala, UPPCL UP, MSEDCL, or BESCOM), select your connection category (Domestic or Commercial), enter your total units consumed in kilowatt-hours (kWh) or meter readings, and specify your connected load in kW. The calculator will automatically apply your state's tariff slab rates, fixed charges, fuel adjustment surcharges (FAC), electricity duty, and state government subsidies to display your estimated payable bill amount.
Q2. How much bill for 1 hour AC?
A 1.5 Ton 5-Star Inverter AC consumes ~1.2 units (kWh) per hour under typical Indian summer conditions. At an average electricity tariff rate of ₹7/unit, running a 1.5 Ton AC for 1 hour costs approximately ₹8.40. A 3-Star non-inverter AC consumes ~1.6 units/hour, costing ~₹11.20 per hour.
Q3. How much is 300 units of electricity?
The cost of 300 units depends heavily on the state, DISCOM, billing period, tariff category, fixed charges, adjustments and subsidy eligibility. Use the state calculator for a breakdown instead of relying on a single India-wide rate.
Q4. How to calculate the monthly electricity bill?
To calculate your monthly electricity bill, use the formula: Energy Charges = Σ (Units in Slab × Slab Rate) + Fixed Charge (Sanctioned kW × Rate) + FAC Surcharge + Electricity Duty - Government Subsidy. Our online tool automates this entire calculation instantly for all Indian discoms.
Q5. How many rupees is 200 units of electricity?
In most Indian states, 200 units of electricity costs between ₹800 and ₹1,200. However, 200 units is 100% free (₹0) in Delhi, Karnataka (Gruha Jyothi), and Telangana!
Q6. Can we run AC for 12 hours?
Yes, modern 5-Star inverter ACs are engineered for continuous 24/7 operation. Running a 1.5 Ton inverter AC for 12 hours at 24°C consumes about 14.4 units per day, resulting in a monthly bill of ~₹3,000.
Q7. Is 2 fan equal to 1 AC?
No! Two ceiling fans consume only 150 Watts total (or 56 Watts for BLDC fans), whereas a 1.5 Ton AC consumes 1,200 to 1,600 Watts. One AC uses as much electricity as 8 to 10 ceiling fans combined.
Q8. How much is 40 units of electricity?
40 units is a low domestic consumption tier costing ~₹80 to ₹160 in most Indian states. For example, under Kerala KSEB, 40 units costs ₹116 at ₹2.90/unit.

Q10. How much bill for 100 units of electricity?
The cost of 100 units depends on the state tariff and billing period. Some states have subsidy or free-unit schemes for eligible consumers, so the payable amount can be much lower than the energy-charge subtotal.
Q11. Can I leave AC on for 2 days?
Technically yes, inverter AC compressors automatically adjust cooling power once the room temperature stabilizes. However, running continuously for 48 hours without breaks consumes ~57 units (~₹400) and increases dust accumulation on filters.
Q12. Can we sleep in AC every day?
Yes, sleeping in an AC set between 24°C and 26°C with proper ventilation and clean air filters is safe, comfortable, and energy-efficient for daily sleep.
Q13. How much to run AC overnight?
Running a 1.5 Ton 5-Star Inverter AC overnight for 8 hours at 24°C consumes approximately 9.6 kWh units, costing between ₹65 and ₹75 per night.
Q14. What is kWh in electricity bill calculator
kWh stands for Kilowatt-hour, which is the standard unit of electrical energy measurement used by power discoms across India. One kWh is equivalent to 1 Unit of electricity on your meter. It represents consuming 1,000 Watts of power for 1 hour.
