Use-case cost estimate

How Much Does an AI Image Generator Cost?

Image generation cost depends on the selected model, resolution, quality or processing tier, images per action, and active usage.

Default workload assumptions

These values make the example reproducible. They are planning assumptions, not measured usage from your application.

Formula

monthly image cost = price per image × images per run × runs per user per day × active users × 30

Main cost drivers

  • Resolution and output quality
  • Number of variants generated per user action
  • Regeneration and failed-output rate
  • Prompt and image-input charges not included in per-image output

Ways to reduce cost

  • Generate fewer default variants
  • Use lower resolution for previews
  • Upscale only selected outputs
  • Set clear limits for free or trial users

Frequently asked questions

Does price per image include prompt tokens?

Not necessarily. The example uses the catalog's per-image output variant and explicitly excludes additional token-priced inputs.

Why model active users instead of registered users?

Only users who generate images create usage cost. Registered-user counts usually overstate demand.

Input tokens

Input tokens are the tokenized units sent to a model, including instructions, user content, conversation history, retrieved context, and tool definitions.

Open

Requests per day

Requests per day is the number of billable API calls made during a day. TokenMath commonly derives it from requests per active user multiplied by active users.

Open

Cost per request

Cost per request is the sum of all billable usage generated by one API call, commonly input token cost plus output token cost for a text model.
