Why would I need to calculate the audiobook time?
Regular physical books cannot be customized. The book you get is all you have, and the speed at which you read it will depend solely on your own reading speed. Audiobooks, on the other hand, can be customized. More to the point, the rate at which they are played can be swiftly changed according to your needs. While using audiobooks, you can:

Discover how long it will take to listen to an audiobook based on different playback speeds. This knowledge lets you plan your time effectively and choose books that fit your schedule.

Identify the optimal playback speed that allows you to enjoy an audiobook within a specific timeframe. Whether you have a limited window or a set deadline, knowing the right playback speed ensures you can savor the entire story within your available time.

Determine the appropriate audiobook length to match your required playback speed and available free time. By understanding the relationship between playback speed and audiobook length, you can choose audiobooks that align with your time constraints and speed preferences.
Calculating audiobook time: some practical examples.
Now that you know what you can do with an audiobook, let's have a look at some practical examples:
Scenario 1: Complex physics book
Imagine you're listening to a complex physics book and decide to listen to it at a slower pace to enhance your comprehension. Suddenly, everything becomes much easier to understand! However, an anxious thought soon pops into your mind: Will you have enough time now to listen to the entire audiobook before your exam? Considering you will have approximately 30 hours dedicated to listening, you can find out whether you will manage to listen to the whole book by setting the playback speed to 0.5 and verifying if the total listening time is 30 hours or less.
You may even combine it with the reading time calculator to find out how to best split your 30 hours of dedicated listening.
Scenario 2: Limited free time
Suppose you have only 30 minutes of free time per day and wish to know how the playback speed affects the number of audiobooks you can listen to in a month. Using the audiobook calculator, you can set the playback speed to your desired value and observe the time it will take to listen to the entire book. Once you are done, you can even input this data into the audiobooks calculator and determine the number of audiobooks you can enjoy in a month or a year.
Scenario 3: Time constraints
While selecting a new audiobook, you realize you face some constraints: you can only spend about 6 hours listening to the entire book, and your maximum playback speed is two. What should you do? Well, you could sit down and try to do all of the calculations by hand, or... you could simply head to our audiobook speed calculator and input your playback speed and total listening time. The audiobook speed calculator will then quickly calculate the audiobook length that meets your requirements and tell you exactly which audiobook length you should go for.
Do you relate to any of these examples? Then, make sure to find a solution to them with the help of our audiobook speed calculator! This is the perfect tool to effectively manage your time and enjoy a fulfilling audiobook experience.
How does the audiobook speed calculator work?
The audiobook calculator uses two main formulas to provide essential information about your listening experience. Keep reading to explore how this calculator works and its underlying reasoning.
Total listening time
The total listening time is calculated by dividing the audiobook length by the chosen playback speed. The formula is:
For instance, if you have an audiobook with a calculated audiobook length of 10 hours and you choose a playback speed of 1.5x, the 1.5x speed calculation would be as follows:
This means that by listening to the audiobook at 1.5x speed, you can complete it in approximately 6 hours and 40 minutes.
Listening time saved
The listening time saved is the difference between the audiobook's original length and the total listening time you got by adjusting the playback speed. The formula is:
Continuing with the previous example, where the audiobook length is 10 hours and the total listening time at a calculated 1.5x speed is 6.67 hours, the calculation would be as follows:
So, listening to the audiobook at 1.5x speed saves approximately 3 hours and 20 minutes of listening time. That's a lot of time that you could spend doing something else!
How to use the audiobook speed calculator
As we have seen above, calculating the total listening time and listening time saved is super easy. It all boils down to simple arithmetic calculations. However, that doesn't mean you always need to do it all yourself! If it so happens that you are in a hurry and cannot do this by hand, our audiobook length calculator is here to help. Below, we explain exactly what you need to do to quickly find the audiobook length without even thinking twice.

Fill in the known data:
Start by entering the values you know into the appropriate fields. These include the audiobook length, the total listening time, and the listening time saved. You can input either two of them to get the results.
In case you don't know these values, you can also simply leave the present values that come with the playback speed calculator. These values represent an average audiobook and can be used whenever you are not fully sure about your own.

Observe how the values change in your audiobook calculator:
Once you've filled at least two of the available fields, the audiobook calculator dynamically updates the other values based on the given inputs.
Take a moment to observe how these values change as you adjust the playback speed or modify other variables. This will help you understand the relationship between the playback speed and the resulting listening time.

Explore different scenarios:
Now that you know how to use this tool, you can try experimenting a bit. Consider changing some of the settings to see how they affect each other. Who knows, you might come across some very interesting relationships!
