## What is the formula to calculate power consumption?

**How to Calculate Power Consumption in kWh?**

- Daily Power Consumption. Daily Power Consumption = Wattage rating x time in hours. 2000 Watts x 3 Hrs = 6000 Watts-Hour. …
- Monthly Power Consumption. Monthly Power Consumption = Wattage rating x time in hours. 2000 Watts x 3 Hrs x 30 days = 180000 Watts-Hour. …

## How do you calculate appliance consumption?

Compute the watts the device consumes daily.

**Multiply the wattage by the average number of hours the device is used per day**. Let’s say you use a 100-watt electric fan for 10 hours per day. Multiplying 100 watts by 10 hours will result in 1,000 watt-hours—that’s how much your electric fan consumes in a day.
