Why this isn't trivial
The part people underestimate: TTS is priced per character (or per second of audio), so the length of what you synthesize sets the cost. In practice the biggest savings come from synthesizing only what changes and caching stable audio, so it is worth modelling before you commit.
How it's calculated
We estimate this by multiplying per-character TTS price by characters synthesized per month. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.
Frequently asked questions
How is TTS priced?+
Usually per character or per second of generated audio, by model quality.
Can I cache audio?+
Yes — cache stable phrases so you don't re-synthesize the same text.
Are these prices up to date?+
Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
