Monitor Power Calculator
Calculate monitor power consumption and estimate electricity costs
Enter Power Consumption
Find your monitor’s power consumption in the specs or select a preset. Typical values: 25-35W for standard monitors, 50-70W for large/high-brightness displays.
Set Daily Usage
Enter how many hours per day you use your monitor. 8 hours is typical for work use, 4-6 hours for casual home use.
Enter Electricity Rate
Check your electricity bill for the rate per kWh. Average US rate is around $0.12/kWh. Rates vary significantly by region.
Panel Type Impact
IPS panels typically use slightly more power than VA. OLED varies based on content brightness. Mini-LED uses more during HDR.
Brightness Effect
Higher brightness settings significantly increase power draw. Running at 50% brightness vs 100% can reduce consumption by 30-40%.
Energy Saving Features
Enable auto-brightness, screen timeout, and power-saving modes. Eco mode on many monitors can reduce power by 20-30%.
Standby Power
Most monitors draw 0.3-0.5W in standby. Over a year, this adds up. Consider using a power strip to fully cut power when not in use.
