Audiobook Speed Calculator

Calculate the actual listening time for an audiobook at any playback speed (1.25x, 1.5x, 2x) and total time saved over normal speed.

Frequently Asked Questions

What is 2x speed in minutes saved per hour?

30 minutes saved per real-time hour. A 10-hour book becomes 5 hours of actual listening.

Why does 1.5x save 33% not 50%?

Because saved fraction = 1 - 1/speed. At 1.5x, you save (1 - 0.667) = 33.3% of the original time.

Will I miss anything?

Depends on the book. Dense academic content suffers; novels and memoirs usually work fine at higher speeds.
