Power Consumption Calculator

How to use

1. Wattage from the sticker.
2. Hours per day it actually runs.
3. Days in the month and your unit rate.

One example

100 W, 8 hours, 30 days is 24 units. At ₹8 that is ₹192. Small, until you add ten such things.

Common mistakes

• Using 1500 W for a 1.5 ton AC without checking star rating. Real draw varies.
• Counting 24 hours when the fridge compressor is not on 24 hours.
• Forgetting inverter AC cycles down.
