When you're watching videos, listening to podcasts, or going through recorded lectures, playback speed is your secret weapon for saving time. Our playback speed calculator helps you instantly see how much time you'll save by adjusting your content's speed.
How to use this calculator:
- Enter your content's original length in hours, minutes, and seconds
- Select your desired playback speed using the slider (0.5x to 3x)
- See your new viewing/listening time and total time saved
For example, a 1-hour podcast at 1.5x speed will take just 40 minutes to complete, saving you 20 minutes.
What Can You Calculate With This Tool?
This calculator helps you:
- Determine exactly how long a video or audio file will take to watch/listen at different speeds
- Calculate precise time savings compared to normal (1x) speed
- Plan your content consumption schedule more efficiently
- Compare time investment across different playback speeds
The Playback Speed Formula
The calculation behind our tool is straightforward:
New Duration = Original Duration / Playback Speed
Time Saved = Original Duration - New Duration
