# Plans and limits

> Choose the right Braintrust plan for your needs

### Usage limits

Usage limits determine how much data you can log, score, and retain based on your plan. On-demand usage rates apply when your usage grows beyond the included limits on Starter or Pro plans.

| Limit                                                                                                                                                                                                                                                                                                                                  | Starter                            | Pro                                | Enterprise |

<Tip>
  Pro plan on-demand usage rates are lower and provide better economics as your usage scales.

### Topics usage

[Topics](/observe/topics) is metered separately from processed data and scores. All plans include a monthly Topics credit. On-demand overage rates are uniform across plans and apply once the credit is used up.

<Note>
  Topics credits do not roll over month-to-month. On Starter, if you exhaust your credit and haven't [enabled on-demand usage](/admin/billing/change-plan#enable-on-demand-usage), Topics is paused until the next monthly cycle or until you add a card.
