Simply enter the original listening time of an audiobook and set the desired playback speeds. Let the Audiobook calculator enhance your audiobook listening experience to the next level.
Audiobook Calculator
An Audiobook Length Calculator helps you to know how much time it would take you to finish listening to an audiobook at different playback speeds. It is useful in both cases, whether trying to save time by listening at 1.5x or 2.0x speed or prefer slowing down the pace to listen correctly.
Read on to walk you through how to use this audiobook calculator and explain the mathematical formulas behind it.
How to Use the Audiobook Calculator
There are two parts to the audiobook speed calculator. The upper half is for the inputs and the lower with the adjusted time and time saved results separated by a calculate button. With the proper inputs and clicking on the calculate should show you the adjusted time and the total time saved or lost when you set playback speeds below 1.0x. Here are the steps to use an audiobook calculator:
Step1: Enter the Audiobook’s Original Length:
In the calculator, you’ll see three fields where you can input the original length of the audiobook:
- Hours
- Minutes
- Seconds
For example, if your audiobook is 11 hours and 33 minutes and 54 seconds long, you’d enter:
Hours: 11
Minutes: 33
Seconds: 54
Step2: Select the Playback Speed:
You’ll also see a dropdown menu where you can choose the playback speed:
0.5x (half speed, for slower listening)
1x (normal speed, the default playback speed)
1.5x (faster, often used for quick comprehension)
2x (double speed, commonly used to breeze through content)
Custom (Useful to add micro increments to the playback speed for better listening)
Select the speed that you typically use when listening to audiobooks.
Step3: Click “Calculate”:
Once you have properly entered the original length and playback speed of an audiobook then click on the Calculate button. Clicking the calculate button should show you the following:
Adjusted Time: how long it will take to finish the audiobook at the selected playback speed.
Time Saved: how much time you’re saving by listening faster than the normal speed.
Testimonial of Audiobook Speed Calculator
For example,
you are planning to listen to an audiobook “The Women: A Novel” written by Kristin Hannah and co-narrated by Julia Willan.
The original length of this audiobook advertised on Amazon is 14 hours, 57 minutes, and 0 seconds at normal speed. What would it take to listen at 1.5x, 1.25x, or 2x playback speed?
Let’s calculate the adjusted and time saved using the above calculator.
Original Length: 14 hours 57 minutes 0 seconds (14:57:0)
Playback Speed: 1.25x
By using the calculator:
The adjusted time would be 11 hours 57 minutes, and 35 seconds
The time saved would be 2 hours, 59 minutes, and 24 seconds
Mathematical Formulas Behind the Calculator
An audiobook calculator functions on mathematical formulas to determine the adjusted time and Time Saved. So, it’s necessary to understand what going on behind the calculations. Here is the formula breakdown of an audiobook speed calculator and how it performs mathematical magic.
Formula for Adjusted Time:
Here is the formula for how an audiobook calculator makes calculations and provides you with the Adjusted Time
Adjusted Time = Original Listening time of an audiobook / Playback speed
This formula divides the original listening time of an audiobook with the playback speed you set.
For example, If the original listening time of a book is 12 hours and you want to listen at 1.5x playback speed then it will take 8 hours to listen which saves you 4 hours. So, your Time Save should be 4 hours.
Adjusted Time = 12 hours / 1.5x = 8
The formula for Saved Time:
This calculation is simple:
Time Save = Original Time – Adjusted time
For example, if the original listening time is 12 hours and the adjusted time is 8 hours with playback speed set at 1.5x, then the Time saved would be 4 hours.
Time Saved = 12 hours (Original Time) – 8 hours (Adjusted time) = 4 Hours (time saved)
For precise calculations, this calculator carries out the calculation in seconds and multiplies hours, and minutes to perform minute calculations.
Total Seconds = (Hours×3600) + (Minutes×60) +Seconds
Understanding the Key Terms
Here is the explanation of key times
Original Listening Time: It is the listening time of an audiobook at normal speed which is 1.0x.
Playback Speed: The rate at which you’re listening to the audiobook (e.g., 1.5x, 2x).
Adjusted Time: The time it will take to listen to the audiobook at the selected playback speed.
Time Saved: The amount of time you save by listening faster than the original speed.
Audiobook Length Calculated at Different Playback Speeds
For example, an audiobook’s original length is 14 hours and 55 minutes how much time it would take to listen at 1.25x, 1.5x, 2x, and 7x playback speeds? See the table of calculations performed with the above audiobook calculator:
| Original Length of an Audio Book | Playback Speed Set | Adjusted Time | Time Save |
| 14h 55m 0s | 1.25x | 11h 56m 0s | 2h 58m 59s |
| 14h 55m 0s | 1.5x | 9h 56m 40s | 4h 58m 19s |
| 14h 55m 0s | 3x | 4h 58m 20s | 9h 56m 39s |
| 14h 55m 0s | 7x | 2h 7m 51s | 12h 47m 8s |
Why Use an Audiobook Length Calculator?
Time management is an important factor in progress in life. If you want to listen to an audiobook of 8 hours long you have to do other things along. An audiobook speed calculator will give you an estimation with a few small inputs to save your listening time. Just fill out the input fields, and change the playback speeds from 1x to 1.25 would save you enough time to get meals.
If you’re trying to get through content quickly, knowing how much time you’ll save at faster speeds is crucial.
Some people prefer to listen slower or faster depending on the complexity of the content. The calculator helps you adjust accordingly.
By using this tool, you can see the exact time it takes to complete the audiobook and how much time you save by speeding up the playback.
Final Thoughts
The audiobook calculator is a contemporary tool that saves the time of authors, producers, and even listeners in being properly informed to make the right decisions. It’s a facilitator that ensures smooth working processes and enables better time management within the recording process.
An audiobook calculator is a great addition to the workflow, especially when you’re producing audiobooks for business or pleasure. It ensures smooth operations and better outcomes for all stakeholders involved.

FAQs
What is the ideal narration speed of an audiobook?
The ideal narration speed is often at 150-180 WPM, but this depends on what kind of book it is and what the listeners prefer.
What benefit does an audiobook calculator give to authors?
The best advantage of an audiobook calculator is to determine the overall production time, which will later be one’s aid in budgeting planning, and achieving realistic release times for the audiobooks.
Can an audiobook calculator estimate production costs?
Yes, because the cost of producing an audiobook is often directly tied to the time it takes to record, an audiobook calculator will benefit you by producing a total length, making it easier to estimate the narrator fees, studio time, and editing.
What is the difference between an audiobook calculator and a playback speed calculator?
An audiobook calculator will provide the total amount of time to read a book based on word count and narration speed; a playback speed calculator will alter the length of an audiobook at faster or slower playback speeds.
Would an audiobook calculator permit customized narration speeds?
Yes, most of these enable variable or custom speeds so that you can vary the speed on such an audiobook calculator for your specific production or personal desires.
