How to Calculate Audiobook Playback Speed?

To figure out how long an audiobook will take at a faster or slower speed, you can use the formulas given below. It helps you calculate the exact listening time based on the playback speed you choose.

→ Total listening time

Total listening time equals the audiobook length divided by the playback speed. The faster you listen, the shorter the duration becomes.

Total listening time = Audiobook length / Playback speed

Example: 8 hours audiobook at 2x speed → 8/2 = 4hours

→ Listening time saved

The time saved from listening is the gap between the audiobook’s original duration and the total time spent listening after speeding up playback. It measures how much time you saved by increasing the speed.

Listening time saved = Audiobook length - Total listening time

Example: 8 hours audiobook at 2x speed → Total Time = 4 hours.

Time Saved = 8 - 4 = 4 hours

Practical Example:

An audiobook with a length of 7 hours and 30 minutes, played at 1.25x speed. How much time will it take to listen?

Solution:

Given:

Audiobook Length = 7 hours 30 minutes
Playback Speed = 1.25x

Step 1: Convert audiobook time into minutes (or seconds).

7 hours = 7 × 60 = 420 minutes

Add 30 minutes → 420 + 30 = 450 minutes

So, Original Time = 450 minutes

Step 2: Apply the formula

Total Listening Time = Audiobook length / Playback speed

Total Listening Time = 450 / 1.25 = 360 minutes

Step 3: Convert back into hours and minutes

360 minutes ÷ 60 = 6 hours

✅ Final Answer:

At 1.25x speed, the 7 hours 30 minutes audiobook will take exactly 6 hours to finish.
