How to Use This Calculator
1

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.

2

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.

3

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.

Understanding Monitor Power

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.
