AI Voice Generation Cost Calculator
Estimate your script's spoken duration and narration cost before you generate anything. Enter your provider's current rate yourself — pricing changes often, so this tool never guesses a number for you. See thefull cost breakdownfor how per-character and per-request billing actually compare.
Character count is estimated at ~6 characters per word (letters plus spaces/punctuation) — your actual script will vary. This tool doesn't store or send your inputs anywhere; everything runs in your browser.
How to use this
Paste your script's word count (most word processors show this) and pick a realistic speaking pace — 140 WPM is a common conversational default; documentary-style narration often runs slower. For per-character billing, open your provider's current pricing page, find the rate for your plan tier, and enter it here. For per-request billing, enter the chunk size your generation workflow actually uses.
