Accurately calculating your daily electricity consumption lets you pinpoint exactly where your electricity dollars are going, enabling you to make informed decisions and potentially lower your energy costs.

The Basic Formula for Estimating Daily Electricity Usage

You can calculate how much electricity any appliance or electronic device uses each day with a simple formula:

(Wattage × Hours Used Per Day) ÷ 1000 = Daily Kilowatt-hour (kWh)

Example:

Let’s say you have a television that uses 200 watts (check your TV’s manual or label) and you typically watch it for about 4 hours daily:

• Multiply wattage by hours used daily:
  200 watts × 4 hours = 800 watt-hours
• Convert watt-hours to kilowatt-hours by dividing by 1000:
  800 watt-hours ÷ 1000 = 0.8 kWh per day

This means your TV alone consumes roughly 0.8 kWh of electricity per day.

How to Find Appliance Wattage Ratings

Most appliances or devices list their wattage on a sticker or plate, typically located on the back, side, or bottom. You can also find this information in the appliance’s user manual or online on the manufacturer’s website.

If wattage isn't provided but voltage and amperage ratings are, use this alternate formula:

(Voltage × Amperage) = Watts
