Calculating monthly TV electricity costs

The electricity cost per kWh varies by location and provider, but typically ranges from $0.10 to $0.15 per kWh in the US. To calculate monthly TV electricity cost, use the formula: Cost = Power (Watts) × Hours Used × Days × Electricity cost per kWh. For example, a 55-inch smart TV using 77 watts for 4 hours daily costs about $1.02 per month at $0.11/kWh.

How to calculate monthly TV electricity costs

To calculate your monthly electricity consumption for your TV, follow these steps:

• Use the basic formula: Cost = Power (Watts) × Hours Used × Days × Electricity cost per kWh
• Find your TV's power consumption: Check the TV's specifications or energy label for wattage
• Determine your daily usage: Estimate how many hours you use your TV each day
• Know your electricity rate: Find your electricity cost per kWh on your electricity bill
• Convert watts to kilowatts: Divide the wattage by 1000

Example calculation using an electricity usage calculator

For a 55-inch smart TV with 77 watts TV power consumption per day for 4 hours daily at $0.11/kWh:

1. 77 watts ÷ 1000 = 0.077 kW
2. 0.077 kW × 4 hours = 0.308 kWh per day
3. 0.308 kWh × $0.11 = $0.03388 per day
4. $0.03388 × 30 days = $1.02 per month

Factors affecting TV power consumption

Consider these factors when estimating how much electricity does a TV use per month:

• Screen size: Larger screens generally consume more power
• TV technology: OLED TVs are most efficient, followed by LED/LCD, while plasma TVs use the most power
• Picture settings: Higher brightness and contrast increase power consumption
• Smart features: Advanced capabilities may slightly increase power usage

Average power consumption by TV type

• OLED TVs: 30-100 watts per hour
• LED/LCD TVs: 50-100 watts per hour
• CRT TVs: 60-150 watts per hour
• Plasma TVs: Up to 300 watts per hour

Tips to reduce TV electricity costs

Implement these strategies to lower your monthly electricity consumption for your TV:

• Use energy-efficient models: Choose ENERGY STAR-certified TVs, which are typically 25% more efficient
• Adjust picture settings: Lower brightness and contrast in dim environments
• Turn off when not in use: Avoid leaving the TV in standby mode
• Disable unnecessary features: Turn off voice control and Bluetooth when not needed

New energy efficiency standards

Be aware of upcoming changes in TV energy efficiency standards and TV electricity usage per year:

• Starting May 2, 2024, new FTC Energy Labeling Rule requirements will be implemented

Factors affecting TV energy consumption

The cost to leave TV on all day is approximately $0.29. Leaving a TV on all day typically uses 50-200 watts of electricity, depending on factors like screen size and technology type. Monthly consumption for a TV can range from 6-60 kWh. The cost to run a TV for 8 hours is about $0.10. To reduce the TV raise electric bill impact, consider using energy-efficient models and limiting usage time. How much electricity does a TV use per month varies based on these factors, with modern TVs generally being more energy-efficient.

Main factors affecting TV energy consumption

Screen size and technology

• Larger screens consume more power: A 48-inch TV uses about 80 watts, while a 65-inch TV consumes nearly 115 watts
• Technology impacts consumption:
  • OLED TVs are most efficient, consuming 30-200 watts
  • LED TVs use 50-100 watts
  • LCD TVs consume 50-150 watts
  • Plasma TVs use up to 300 watts
  • CRT TVs consume 60-150 watts

Usage duration and settings

• Daily usage hours: A 100W TV used for 2 hours/day consumes 6kWh/month, while 3 hours/day uses 9.1kWh/month, affecting how much electricity does a tv use per month
• Brightness settings: Reducing brightness by 50% can lower energy use, but not proportionally, as other components still consume power
• Standby mode: TVs in standby typically consume 2.25-5% of their active power usage

Cost calculations

Cost to leave TV on all day

To calculate the daily cost:

1. Determine your TV's wattage (e.g., 100W)
2. Multiply by 24 hours: 100W * 24 = 2400Wh or 2.4kWh
3. Multiply by your electricity rate (e.g., $0.12/kWh): 2.4kWh * $0.12 = $0.288 per day

Cost to run a TV for 8 hours

Using the same method:

1. TV wattage: 100W
2. Multiply by 8 hours: 100W * 8 = 800Wh or 0.8kWh
3. Multiply by electricity rate: 0.8kWh * $0.12 = $0.096 per 8-hour period

Impact on electric bill

• Monthly consumption: A 100W TV used 4 hours daily consumes about 14.2kWh/month, illustrating how much electricity does a tv use per month
• Annual cost: Multiply monthly consumption by 12 and your electricity rate to get yearly cost
• Comparison to other appliances: TVs have a relatively low power requirement compared to devices like coffee machines (1,000W) or AC units (2,500W)
