Cartesia pricing — frequently asked questions
How much does Cartesia cost per month? ▼
Cartesia's self-serve plans are Free (20,000 credits/month), Pro at $4/month (100,000 credits), Startup at $39/month (1.25 million credits), and Scale at $239/month (8 million credits). Scale is fully self-serve — not a sales-gated tier. Above Scale, Enterprise uses custom credit and agent volumes with volume pricing negotiated with sales.
What is a Cartesia credit and how does it convert to audio? ▼
Credits are consumed per second of generated audio on the flagship Sonic-3.5 text-to-speech model, and the included minutes scale with the plan: roughly 27 TTS minutes/month on Free, ~133 on Pro, ~1,667 on Startup, and ~10,667 on Scale. Premium features cost extra credits — the voice changer is 15 credits per second of audio, and localizing a voice is a one-time 225-credit cost.
Does Cartesia have a free tier and is a credit card required? ▼
Yes. The free tier provides 20,000 credits per month with no credit card required at signup, plus a $1/month prepaid balance for voice agents. Free-tier users get the Sonic-3.5 text-to-speech and Ink-2 speech-to-text models, unlimited workspace seats, and one voice agent slot.
How is Cartesia's voice-agent pricing different from per-second TTS? ▼
Cartesia's Line voice agents are billed at a flat $0.06 per minute of call duration on every plan — Free, Pro, Startup, and Scale all pay the same rate — plus $0.014 per minute of telephony when you use a Cartesia-provided phone number. Agents draw from a prepaid dollar balance ($1/mo on Free up to $299/mo on Scale) rather than a bundle of included minutes.
Is this Cartesia pricing calculator free and accurate? ▼
Yes — it's completely free with no signup. It uses the latest publicly available Cartesia pricing (verified May 2026). Actual costs may vary with volume discounts or enterprise terms — always confirm on Cartesia's official pricing page.
