Manuscript planning

Audiobook calculator: words to minutes, hours and budget

Words to minutes, and on to hours: paste a script, a chapter or a speech and see it counted and timed as you type — or open the actual manuscript and separate front and back matter. Either way you get the speaking time in minutes, finished audiobook hours, a per-finished-hour budget and production time at a reading pace you set, and nothing is uploaded.

Or paste the text instead

For a script, a chapter, a speech or anything you have not got as a file. It is counted as you type, in this tab; nothing is sent anywhere.

How the number is derived

Four steps, none of them hidden

Every value comes from the words in your own file and the three inputs above. Change an input and the whole chain moves.

Words to minutes

How long a word count takes to read aloud

Speaking time is the word count divided by the pace. These are the three paces the calculator offers; paste your own text above for the exact figure, since dialogue, pauses and hard names all slow a read.

Assumptions and limits

What the number means, and what it is not

The pace is an assumption you can replace

The default pace is 9,300 words per finished hour, the planning formula documented in Erin Wright’s audiobook calculator. A performance with dialogue, accents, pauses or technical language can be slower; a brisk non-fiction read can be faster.

The section list is visible so you can correct exclusions yourself instead of trusting an opaque “narrative word” guess made on your behalf.

What this deliberately does not do

  • Turn a book into synthetic speech
  • OCR a scanned PDF — run OCR first, then come back
  • Estimate pickups, retakes or proof-listening passes
  • Promise a production quote — it is a planning baseline

Next production checks

After the book is planned

  1. Per chapter Check and fix one ACX chapter The five numbers measured, the fixable ones corrected, a compliant MP3 exported.
  2. Before delivery Check consistency across the finished book Every chapter against the book's own median, so one loud chapter does not slip through.

Straight answers

Questions about words, minutes and budgets

How many words are in an hour of audiobook?

The default planning pace here is 9,300 words per finished hour, the figure documented in Erin Wright's audiobook calculator. A performance with dialogue, accents or technical language runs slower and a brisk non-fiction read runs faster, so the pace is an input you can replace.

How do I convert words to minutes?

Divide the word count by the reading pace. At a typical 155 words per minute, 1,000 words take about six and a half minutes to read aloud. Paste the text into the page and the minutes update as you type.

How many minutes is 1,000 words?

About six and a half minutes at 155 words a minute, the pace this page starts from. At a measured 140 words a minute it is a little over seven minutes, and at a brisk 170 a little under six. The Speaking time card shows the figure for your own text at whichever pace you pick.

How many words is a ten-minute speech?

About 1,550 words at 155 words a minute, 1,400 at 140 and 1,700 at 170. Paste a draft and change the pace to see where yours lands; the minutes are worked out from the words you actually have, not from a page count.

Which manuscript formats can it read?

EPUB, text-based PDF, DOCX and TXT, or text pasted straight into the page. A scanned PDF has no text to count and needs OCR first. Every section is listed so front and back matter can be left out chapter by chapter.

How is the narration budget worked out?

Finished hours times the rate per finished hour you enter, and production time is finished hours times the production hours per finished hour you enter. Both are your planning inputs, not a quote. Add a list price and your royalty percentage and it also works out the royalty-share breakeven.

Is my manuscript uploaded?

No. The file or the pasted text is read inside this browser tab and nothing is sent anywhere, which is why a manuscript under NDA can be estimated here.
