# How credits work

> Prepaid credits, one price per generation shown before you click, and automatic refunds when something fails.

_Help center › Credits, plans & billing_

Everything on eroq is metered in prepaid credits. Every generation costs a set number of credits shown on the button before you commit, and the number never changes after the fact. One credit is about one cent at the entry pack rate.

## What things cost

- Images: a fixed price per image, set by the model (10 credits on most engines), times the number of takes.
- Video: a per-second rate set by the engine and the resolution, plus a little more with sound where it is optional. Motion One is a flat price per clip; the others are listed per second on their model pages.
- Voice: 3 credits per started block of 100 characters on Voice One, 2 on Voice Turbo. Transcription: 1 credit per started minute of audio.
- Text: 1 to 3 credits per reply depending on the model.
- Free: prompt enhancement, dictation, the Ask bar, saving to the Library, uploads to Storage, publishing.

## Refunds on failure

A generation that fails refunds itself, as a negative row in your usage ledger. A render with several takes refunds each failed take on its own. A prompt an engine declines returns content_blocked and is never charged.

## Whose credits are they

Credits belong to the workspace, not the person: everyone in a workspace spends from one balance, and an admin can cap what each member spends per month. Credits never expire, and unused plan credits roll over.
