About these tools
The numbers behind audiobooks are simple once you know the rates: narrators read about 155 words a minute, narrators are paid per finished hour, and ACX pays 50% exclusive or 30% non-exclusive. These calculators work them out for your book.
Authors can go from a manuscript to finished hours, narration budget and royalties; listeners can see how much time a faster speed saves and how many books fit in a year. Rates are dated and sourced on each page.
