How do you calculate audiobook listening time?

Divide the audiobook length by your playback speed. An 11 hour 26 minute audiobook takes 7 hours 37 minutes at 1.5x, saving 3 hours 49 minutes, and 5 hours 43 minutes at 2x. For a book that is not recorded yet, divide the word count by about 9,300 words per finished hour: 80,000 words make an audiobook of about 8 hours 36 minutes. The audiobook calculator above does both as you type.

How to use the audiobook calculator

Three steps, and the results update while you type.

  1. Pick what to work out

What this audiobook calculator does for you

Listeners and authors get their answers on one page, with numbers that add up.

Listening time and time saved add up to the minute

Rounding each figure on its own can make them miss the book by a minute. We round the listening time once and subtract, so 7 h 37 min plus 3 h 49 min is exactly the 11 h 26 min you entered.

Authors need audiobook length before a single chapter is recorded. The industry estimate is 9,300 words per finished hour, about 155 words a minute; pick 140 or 170 for a slower or brisker reader, or paste the manuscript to count it.

How playback speed changes audiobook time

Listening time is the audiobook length divided by the speed, the rule behind every audiobook time calculator. A 10 hour audiobook takes 8 hours at 1.25x, 6 hours 40 minutes at 1.5x, 5 hours at 2x and 4 hours at 2.5x.

The time you save grows more slowly than the speed. Going from 1x to 1.5x is 50% faster but saves a third of the time; 2x saves half; 3x saves two thirds. The share saved is 1 minus 1 divided by the speed.

How long is an audiobook?

Audiobook length follows the word count. At the industry estimate of 9,300 words per finished hour, a 50,000 word novella runs about 5 hours 23 minutes, a 70,000 word novel about 7 hours 32 minutes, 90,000 words about 9 hours 41 minutes and 120,000 words about 12 hours 54 minutes.

Narrators differ. Most read between 140 and 170 words a minute, so an 80,000 word book lands between 7 hours 51 minutes and 9 hours 31 minutes. The Words mode of the audiobook calculator shows that range next to the estimate.

Track audiobook progress as a percentage or page

Your progress is the time listened divided by the audiobook length, which makes the Progress mode an audiobook percentage calculator. Multiply it by the print page count to get the matching page, which is what reading trackers such as Goodreads and StoryGraph ask for.

  1. 1Enter the audiobook length, then the time you have listened (or the percent your app shows).
  2. 2Add the page count of the print edition if you log pages.
  3. 3Read the percent, the page and the time left at your speed.

Plan when you will finish an audiobook

Days to finish are the listening time left divided by the minutes you listen a day, rounded up. 7 hours 37 minutes at 30 minutes a day takes 16 days; today counts as day 1.

Working back from a date, the speed you need is the audio left divided by the minutes you have. To finish an 11 hour 26 minute audiobook in 14 days at 30 minutes a day, you need 1.65x, rounded up to the next 0.05 step.

Audiobook length and cost for authors

Narration is usually priced per finished hour: an hour of the final audiobook, not an hour in the studio. A finished hour takes about 6.2 hours of work, 2 to record, 3 to edit and 1.2 to review, and estimates of 5 to 7 hours are common.

The budget is your rate times the finished hours. An 80,000 word manuscript makes about 8.6 finished hours; at $250 per finished hour that is about $2,150, with about 53 hours of studio time. Rates are set per agreement, so the audiobook calculator uses the one you enter.

Listening faster and subscription hours

Some plans include a set number of audiobook hours a month. Spotify counts those hours at normal speed: a 5 hour audiobook at 2x takes you 2 hours 30 minutes but uses 5 hours of the allowance. Speed saves your time, not the plan’s hours, so plan by audiobook length.
