Formula: credits = TTS characters × 1 (Sonic, incl. Pro Voice Clone speech) + break tags × 1 + STT seconds × 3 (Ink). Audio minutes are converted at your characters-per-minute (Cartesia cites ~750–800 credits per minute). Plans: Free $0 / 20K credits (no overage) · Pro $5 / 100K · Startup $49 / 1.25M · Scale $299 / 8M · Enterprise custom. Optional overage on paid plans: Pro $65, Startup $45, Scale $38 per 1M credits; with overage off, requests stop at zero balance. Unused credits roll over up to 2× the monthly allowance (not modeled). Total = plan fee + overage; effective $ = total ÷ credits. Not included: voice agents ($0.03 / min from prepaid agent dollars; Cartesia phone numbers $0.014 / min), telephony and LLM usage.
Estimates only. Official list prices as of 2026-11-01 (Asia/Shanghai); the provider's pricing page prevails. Sources: Cartesia pricing
