I priced out text-to-speech for a side project this week and the gap made me stop and redo the math twice. OpenAI's tts-1 costs $15 per 1M characters. ElevenLabs' Creator plan, converted to the same unit, costs about $182 per 1M characters. That's not a typo. Same job — text in, audio out — and one provider charges roughly 12x the other. Both numbers come straight from our tracked price registry, not a promo page or a calculator someone forgot to update.
ElevenLabs doesn't quote a per-character rate up front — it sells "credits" in a monthly plan. Do the division and the real rate falls out:
| Provider | Plan | Included | Price | Effective $/1M chars |
|---|---|---|---|---|
| OpenAI | tts-1 (pay-as-you-go) | unlimited | $15.00/1M chars | $15.00 |
| ElevenLabs | Creator | 121,000 credits/mo | $22.00/mo | ≈$181.82 |

In dollar terms: convert 1 million characters (roughly a 170,000-word audiobook script) through OpenAI and you pay $15. Run the same script through ElevenLabs' Creator plan and you're paying $182 — you'd need more than 8 months of the $22 plan just to cover the character count, and that's before you've used a single credit on anything else that month.
Because tts-1 and ElevenLabs are not the same product wearing different price tags. OpenAI's tts-1 is a flat, fairly generic voice synthesizer — six preset voices, no cloning, no fine control over emotion or pacing. It's built to be cheap and good enough for notifications, accessibility read-aloud, or IVR prompts where nobody is scrutinizing the performance.
ElevenLabs sells voice acting. Instant voice cloning from a sample clip, per-word emotional control, 70+ languages with matched accents, and a model quality gap that's obvious the moment you A/B the same sentence. Audiobook narrators, dubbing studios and character-voice game studios pay the premium because tts-1 audibly sounds like a machine reading text, and ElevenLabs — most of the time — doesn't. You're not paying 12x for the same product; you're paying for a different one that happens to share a category name.
Below serious volume, check the free tier before running this math at all. ElevenLabs gives 10,000 credits/mo free — enough for a few short narrations or a prototype demo, not enough for production. OpenAI's tts-1 has no standing free tier; you pay the $15/1M rate from the first character, though new API accounts often get trial credit that covers early testing. A weekend project reading out a handful of notifications a day can live on ElevenLabs' free tier indefinitely and never touch either price.
Per character, OpenAI's tts-1 is roughly 12x cheaper than ElevenLabs' Creator plan — that's the real number from providers' own pricing pages, tracked in our registry, not a rumor from a comparison blog. What the premium buys is real: cloning, emotional control, and a voice that doesn't sound synthesized. If your use case is functional — read this alert out loud — take the cheap option and don't look back. If the voice itself needs to carry the product, the 12x isn't a ripoff, it's the price of the thing you're actually buying. Either way, run your own character volume through the calculator before you commit to a monthly plan — credits and per-character rates don't compare cleanly until you convert them to the same unit.
