How to Use This Calculator
Enter the average duration of videos in the playlist and the total number of videos. The calculator shows the total watch time at normal speed and at your chosen playback speed. This is useful for planning study sessions, binge-watching, or estimating how long a course or series will take to complete.
Playback Speed Comparison
YouTube supports playback speeds from 0.25x to 2x. Watching at 1.5x saves you 33% of the total time, while 2x speed cuts viewing time in half. Most people find 1.25x–1.5x comfortable for educational content without losing comprehension.
