How to Calculate Your TV’s Electricity Usage

Calculating your TV’s exact electricity consumption is straightforward with the right formula. Here’s a step-by-step guide:

Basic Calculation Formula

The fundamental formula for calculating electricity usage is:

kWh = (Watts × Hours Used) ÷ 1000

Where:

• Watts = Your TV’s power consumption
• Hours Used = Daily viewing time
• kWh = Kilowatt-hours (the unit your utility company charges for)

Step-by-Step Calculation Example

Let’s calculate the electricity usage for a 55-inch LED TV (80 watts) watched 5 hours daily:

1. Daily Usage: 80W × 5 hours = 400 watt-hours
2. Convert to kWh: 400 ÷ 1000 = 0.4 kWh per day
3. Monthly Usage: 0.4 kWh × 30 days = 12 kWh per month
4. Annual Usage: 12 kWh × 12 months = 144 kWh per year

Cost Calculation

To calculate your costs, multiply your kWh usage by your electricity rate:

Cost = kWh × Electricity Rate (per kWh)

Using our example with the national average rate of $0.164/kWh:

• Daily Cost: 0.4 kWh × $0.164 = $0.066
• Monthly Cost: 12 kWh × $0.164 = $1.97
• Annual Cost: 144 kWh × $0.164 = $23.62
