TTS savings calculator: ElevenLabs vs Audra at volume — Audra

TTS bills compound quietly — a course platform rendering 2M characters monthly pays ~$240 on ElevenLabs list vs ~$50 on Audra entry tier. Use /calc to model your volume; this post explains what to plug in.

What to measure

• Total characters synthesized per month (not API calls)
• Peak vs average — Audra meters actual rendered chars
• Failed renders — Audra auto-refunds QA failures
• Commercial unlock — first paid pack on /pricing

When Audra wins

Batch narration above ~200k chars/month, OpenAI SDK clients you do not want to rewrite, and teams that need −16 LUFS mastering without a separate ffmpeg step. When realtime cloning matters, compare honestly at /vs/elevenlabs.

Run the numbers: /calc → /migrate → free trial at /dashboard.
