Main factors

Cursor converts the plan's monthly included API usage into model-specific request estimates, then adjusts for agent mode and context size.

Limit basis: Monthly included API usage converted to request equivalents. Cursor publishes approximate model-specific request counts, so model choice matters.

Cursor converts included monthly API usage into approximate request counts, so the selected model strongly affects the result.

FAQ

Quick answers about how the estimator treats remaining percentage, reset windows and unofficial AI usage ranges.

Does this calculate exact tokens?

No. It estimates prompts, tasks, messages or usage units from your remaining percentage.

Why is it approximate?

AI platforms use dynamic limits based on plan, model, system capacity, context, files and task complexity.

What does remaining percentage mean?

It is the percentage the platform shows as remaining, not the percentage already used.

Is this official?

No. It is an independent estimator.
