Synthesia credits calculator
Convert any Synthesia credit amount — or a whole plan’s pool — into minutes and seconds of avatar video. Synthesia moved from minutes to credits in its plan metering; this converts back to the unit you actually plan in.
Quick answer: Synthesia charges 2 credits per second of generated video — 120 credits per minute. The free Basic plan’s 1,200 monthly credits are ≈ 10 minutes; Starter’s 14,500 annual credits are ≈ 120 minutes a year; Creator’s 44,000 are ≈ 360 minutes a year.
Rate and pool sizes read on Synthesia's help center and pricing pages, verified Jul 2026 (2 credits/second, one shared pool; annual pools shown for Starter/Creator). Regenerations bill their seconds again. Whether unused annual credits roll over is not confirmed on a primary Synthesia page — treat results as planning figures.
How Synthesia credits convert
Synthesia replaced per-minute metering with credits, and the published conversion is fixed: 2 credits per second of generated video, 120 per minute, drawn from one shared pool. The migration math, the per-plan pools and the one open question (annual rollover isn’t stated on a primary page) are covered in our Synthesia credits-per-minute explainer.
Before committing a budget to a pool, two policy pages matter as much as the rate: cancellation ends access to every video in the account (the video-access catch), and stock avatars carry a paid-promotion ban regardless of plan (the commercial-use rules).

Before you pick a Synthesia tier
Synthesia meters an annual minute pool rather than a monthly one, so the question is whether your yearly volume fits — not whether a given month does. Check the figure above against the plan you are considering.
