You’ll want to look for the power rating section, which will indicate the average watts consumed when the TV is in use.
Power Calculation Example
Assume you have a 55-inch LED TV with a power rating of 120 watts. To calculate the monthly consumption:
- Determine how many hours a day you watch TV. For example, let’s say 4 hours.
- Calculate the total daily consumption:
- Daily Usage = Power (W) × Hours Watched
Daily Usage = 120 W × 4 hours = 480 Wh (or 0.48 kWh)
To find the monthly usage, multiply your daily usage by 30 (days):
- Monthly Usage = Daily Usage × 30 days
- Monthly Usage = 0.48 kWh × 30 = 14.4 kWh
Finally, multiply your monthly usage by the cost of electricity per kWh to determine your monthly cost of running your TV. For example, if your electricity cost is $0.12 per kWh:
- Monthly Cost = Monthly Usage × Cost per kWh
- Monthly Cost = 14.4 kWh × $0.12 = $1.73
This way, you can see how much energy your TV consumes and how it impacts your monthly electricity bill.
