AI voice cost calculator
Estimate what monthly TTS output costs on ElevenLabs and Speechify Studio — plan price, monthly credits, and cost per 100k characters. Estimates only: ElevenLabs credits are shared across TTS/STT and Speechify Studio credits are separate from the reader app.
Your monthly output
One hour of narration ≈ 60,000–90,000 characters depending on pacing. Adjust to your real production.

Narration length converter
Plan a voiceover: enter your video length (or script word count) and see the estimated narration time, characters, and ElevenLabs credit cost. Assumptions are labeled and adjustable — real per-generation cost varies by voice, model, and pacing.
| Est. narration | Script length | ≈ Characters (ElevenLabs credits) | Cheapest ElevenLabs plan | Plan price |

Assumptions: ~150 words/min default narration pace (adjustable); ~6 characters per word including spaces; ElevenLabs TTS ≈ 1 credit per character (official FAQ and sources). Credits are shared across TTS/STT — a heavy STT user will burn credits faster.
What the numbers mean
ElevenLabs' free tier gives 10,000 credits/month — roughly 10k characters of TTS. Starter at $6/month (annual) adds 30,000 credits with commercial rights on your own voice; Creator tiers scale up to hundreds of thousands of credits. Speechify Studio's free plan gives 600 credits without commercial rights — monetized channels need a paid Studio plan; the Premium reader app ($29/month) is a separate product and does not include Studio generation credits.
