Audiobook Length Calculator

Audiobooks have become one of the most popular ways to enjoy books while multitasking—whether commuting, exercising, or relaxing at home. But one common question every listener has is: How long will this audiobook take me to finish?

That’s where the Audiobook Length Calculator comes in. This simple yet powerful tool helps you estimate the total listening time of a book based on word count, narration speed, and your daily listening habits.

Instead of guessing, you can now plan exactly how many hours or days it will take to complete an audiobook—making your reading goals more achievable.

How the Audiobook Length Calculator Works

The calculator uses three main inputs to give accurate results:

1. Total words in the book – You enter the approximate word count of your manuscript or book.
2. Narration speed (Words Per Minute / WPM) – Select from slow, normal, fast, or even input a custom speed.
3. Daily listening time – Enter how many minutes you plan to listen each day.

With this information, the tool instantly estimates:

• Total audiobook length (hours & minutes)
• Exact total minutes required
• Words per minute used in calculation
• Number of days needed to finish the book

This gives you a clear picture of how long the audiobook will be and how soon you can complete it.
