Quick answer
Units (kWh) = watts × hours used ÷ 1,000. A 1,500 W geyser used 30 minutes a day uses 0.75 units a day, or about 22.5 units a month, which costs about ₹158 at ₹7 per unit. ACs and fridges cycle on and off, so their real use is usually 50–80% of the rated wattage.
How to use this calculator
- Pick an appliance or enter custom watts from its label.
- Enter hours used per day and how many you have.
- Enter the per-unit rate from your electricity bill.
