Let’s break this formula down into understandable elements.
Understanding the Elements of the Calculation
- Wattage: The power rating of your specific TV model.
- Hours Used: The number of hours per day that the TV is actively being watched.
- Price per kWh: This is the rate your utility provider charges you for electricity, typically found on your electricity bill.
Example Calculation
Suppose you have a 65-inch LED TV that consumes 70 watts, and you watch it for 5 hours each day. If your local electricity cost is $0.12 per kWh, here’s how your calculation would look:
- Daily energy consumption:
- 70 watts x 5 hours = 350 watt-hours or 0.35 kWh
- Daily cost:
- 0.35 kWh x $0.12 = $0.042, or about 4.2 cents per day
- Monthly cost:
- $0.042 x 30 = $1.26 per month
Based on this example, watching your 65-inch LED TV for 5 hours a day will cost you about $1.26 per month.
