Use calculatorAudio runs on two numbers: duration and rate. Listeners divide runtime by playback speed to plan their week; producers multiply finished hours by cost-per-finished-hour to budget the book. These calculators serve both sides of the headphones with the same underlying arithmetic.
For authors, the decision that matters most is production path: full PFH (pay upfront, keep royalties), royalty-share (no upfront, split earnings) or hybrid AI-draft-plus-human-finish. The break-even sales count — production cost divided by per-sale royalty — turns that abstract choice into a concrete hurdle to weigh honestly.
Estimates from word counts assume genre-typical narration speeds (fiction ~150 wpm, non-fiction ~160 wpm) with contingency for dramatization. Final runtime always comes from the recording booth, not the manuscript.
