Yes. Leaving a TV on uses electricity the entire time it’s running, so your electric bill will go up—how much depends on the TV’s wattage, your usage hours, and your electricity rate.
Most modern TVs draw somewhere around 50 to 200 watts while playing video, though larger screens, higher brightness settings, and certain display types can push usage higher. To estimate cost, convert watts to kilowatts (divide by 1,000) and multiply by hours used:
Example: A 100-watt TV running 6 hours a day uses 0.1 kW × 6 = 0.6 kWh per day. Over 30 days, that’s 18 kWh. At $0.16/kWh, that’s about $2.88 per month. A bigger, brighter TV at 200 watts would roughly double that.
There’s also standby power (also called “vampire” or “phantom” power). Even when “off,” many TVs draw 0.5 to 5 watts for fast start, Wi-Fi, or background updates. That’s usually a smaller cost than leaving the screen on, but it can add up over a year—especially if you have multiple devices connected (streaming box, game console, soundbar) that also sip power in standby.
If you want a simple way to cut waste, lower the TV’s backlight/brightness, enable energy-saving mode, and power down connected devices when they’re not needed.

For Leaving Your TV On: How Much It Adds to Your Bill, the best answer depends on fit, material, care instructions, and how the product will be used day to day.
Checking those details first helps avoid a poor match and keeps the choice practical after delivery.
Many TVs use roughly 0.05 to 0.20 kWh per hour (50–200 watts), depending on size and settings. At $0.16/kWh, that’s about $0.008 to $0.032 per hour.
