<a name="cost-categories-columns"></a>

You can use the **Cost Category** columns in AWS Cost and Usage Reports to find information about the specific line items categorized by the Cost Categories feature. Cost Category columns are automatically populated when you create a Cost Category and categorization rule. These columns include user-defined Cost Category names as the column headers, and corresponding Cost Category values. Examples include the following:

## costCategory/Project
<a name="cc-details-project"></a>

Use a **Project** Cost Category to categorize cost and usage information associated with the project. Project names such as “alpha” or “beta” will show as values under **costCategory/Project**.

## costCategory/Team
<a name="cc-details-team"></a>

Use a **Team** Cost Category to categorize cost and usage information associated with the team. Team names such as “Marketing” will show as values under **costCategory/Team**.

## costCategory/Environment
<a name="cc-details-env"></a>

Use a **Environment** Cost Category to categorize cost and usage information associated with the environment. Environment names such as “Development” will show as values under **costCategory/Environment**.
