# Tracking Usage

## How Usage Is Counted

The unit of usage in Kolena is called a **credit**.
Credits are consumed whenever an Agent executes a Prompt.
See [our FAQ page](/faq/usage) for details on how to optimize credit usage.

## Managing Credits

Each pricing tier comes with a [monthly credit quota](/tiers#credit-quota-by-tier) of credits.
Monthly credit quotas reset on the first day of each month and do not roll over.

If your monthly credit quota is consumed, you can continue using Kolena with **overage credits**.
These are additional credits that can be purchased in bulk or paid for as you go.
All prepaid credits are added to your Organization's credit balance and will roll over indefinitely.

### Viewing Credit Usage

Credit usage is displayed transparently in multiple locations:

* On the [Manage Organization page](https://agents.kolena.com/organization) for overall usage by Agent
* Within [API responses for individual Runs](/api-reference/add-agent-run)
* Within the details for each Run

To view usage for an individual Run, navigate to that Run in Kolena and open the ellipsis menu in the top-right corner:

### Estimating Credit Usage

The most accurate way to estimate credit usage for an Agent is to create the Agent and then execute a new Run on it.
This will provide an exact measurement of real usage that you can multiply for N Runs.

In addition, Kolena provides a **Credit Calculator** tool to help estimate credit usage.
This is available from your [Organization Usage page](https://agents.kolena.com/organization).
An existing Agent can be selected to estimate based on historical usage, or an estimate can be produced using the number of prompts required and the number of pages in an average Run.

## Legacy Plans: Page-Based Usage

<Note>
  Some existing customers are on page-based pricing plans.
  Kolena will continue to support these plans, but new customers will be on the new user-based pricing plans described above.
</Note>

Usage for your Organization is tracked from the number of pages uploaded.
Each pricing plan comes with a credit of new page uploads per month.
You can view your current usage and remaining credits from [your Organization page](https://agents.kolena.com/organization).
To increase your monthly page upload limit, [contact Kolena](mailto:support@kolena.com) to upgrade your subscription to a higher plan or purchase additional pages with bulk pricing.

### How Are Pages Counted?

Page uploads are counted in the following way for different file formats:

| Uploaded File Type | 1 Page Equivalent            |
| ------------------ | ---------------------------- |
| Scanned Documents  | 1 scanned page               |
| PDF                | 1 PDF page                   |
| Office Documents   | 1 `.docx` or 1 `.pptx` slide |
| Images             | 1 image                      |
| Spreadsheets       | \~70 rows                    |
