Compare TV and Monitor Power Usage
Electricity costs for displays are easy to underestimate. A 55-inch 4K TV running 6 hours daily uses around 300–500 kWh per year — costing ₹2,400–₹4,000 in India, $45–$75 in the USA, or £90–£150 in the UK. A 27-inch monitor uses just 50–100 kWh/year.
How to Calculate TV Electricity Cost
Use this formula to estimate your display's running cost:
Yearly Cost = (Watts × Hours/day × 365 ÷ 1000) × Electricity Rate per kWhExample: A 150W TV at 6 hours/day = 328.5 kWh/year. At ₹8/kWh that is ₹2,628/year.
TV vs Monitor: Which Uses More Power?
TVs use 3–6× more electricity than monitors. A 55" TV averages 100–180W while a 27" monitor uses just 20–45W. For desk work or gaming, a monitor is always the more cost-efficient choice.
OLED TVs are efficient at low brightness but power-hungry at full brightness (120–200W). LED/LCD TVs use 60–140W for 55″. QLED is between both. Compare annual kWh figures on the energy label — this tool uses those when available.
A 55-inch 4K TV at 150W running 6 hours daily uses 328 kWh/year. In India (₹8/kWh) that is ₹2,625/year. In the USA ($0.15/kWh) it is $49/year. In the UK (£0.30/kWh) it is £98/year.
Yes — significantly. A 27-inch monitor uses 20–45W while a 55-inch TV uses 80–180W. Over a year at 6 hours/day, a monitor costs 60–80% less to run.
Standby power is the electricity used when a display is off but still plugged in. Modern TVs use 0.3–1W in standby, adding 2–6 kWh/year at 18 hours standby per day.
1) Use Eco/Standard mode. 2) Enable auto-brightness. 3) Reduce backlight. 4) Set a sleep timer. 5) Unplug when not in use. These steps cut consumption by 20–40%.
