How to use: Set your rate per unit (from your last bill) and number of days. Edit the appliance list with their watts, hours a day and how many you have, or add more rows.
Estimate your electricity units (kWh) and monthly bill from the appliances you use.
How are electricity units calculated?
One unit on your bill is one kilowatt-hour (kWh): 1,000 watts running for one hour. A 1,500 W air conditioner running 6 hours a day for 30 days uses 1,500 × 6 × 30 ÷ 1000 = 270 units.
Where to find the numbers
- Watts: on the appliance label or manual.
- Rate: on your bill. Many Indian states use slab rates, so use your average rate (total energy charge ÷ units).
- Fridges and ACs cycle on and off, so real use is often lower than the label suggests.
VSH take: the biggest savings usually come from the AC, geyser and old fridge, not lights.
Examples
- 1.5 ton AC, 1500 W, 6 h/day, 30 days: 270 kWh. At ₹8 per unit that is ₹2,160.
- Ceiling fan, 75 W, 10 h/day: 22.5 kWh a month, about ₹180 at ₹8.
- 100 units at 8 + fixed 50 + 5% tax: (800 + 50) × 1.05 = 892.50.
