What is it?
The Electricity Bill Calculator shows how much an appliance adds to your electricity bill. It shows the units (kWh) used and the cost per day, per bill and per year.
Who is it for?
Households checking which appliance costs the most, people deciding between appliances, landlords and tenants splitting bills.
How to use it
Enter the Power of the appliance (watts, from its label), How many, Hours used a day, Days and the Price per unit (kWh). The answer appears as you type; there is no Calculate button. Tap Copy result to copy it, or Share on WhatsApp to send it.
What is a unit?
A unit on your bill is one kilowatt-hour: 1,000 watts for one hour. A 1,500 W heater for 2 hours uses 3 units; ten 10 W LED bulbs for 10 hours use 1 unit.
Typical power
- Ceiling fan 50–75 W (BLDC fans about 30 W). LED bulb 9–12 W. LED TV 60–120 W.
- 1.5-ton AC 1,200–1,800 W while the compressor runs (inverter ACs average less). Refrigerator about 1–1.5 units a day.
- Geyser 2,000–3,000 W. Iron 1,000 W. Washing machine 500 W.
Why your bill differs
Many tariffs have slabs and fixed charges, so your bill can differ. Indian bills often charge more per unit at higher slabs, plus fixed charges, electricity duty and fuel adjustment. Use your tariff’s average rate (total bill ÷ units) for the best estimate.
Errors and how to fix them
- Bill much lower than real: your tariff has slabs and fixed charges; use the average rate from your bill.
