# Creating a budget
<a name="budgets-create"></a>

You can create budgets to track and take action on your costs and usage. You can also create budgets to track your aggregate Reserved Instance (RI) and Savings Plans utilization and coverage. By default, single accounts, the management account, and member accounts in an organization can create budgets.

When you create a budget, AWS Budgets provides a Cost Explorer graph to help you see your incurred costs and usage. If you didn't enable Cost Explorer yet, this graph is blank and AWS Budgets will enable Cost Explorer when you create your first budget. You can create your budget without enabling Cost Explorer. It can take up to 24 hours for this graph to appear after you or AWS Budgets enable Cost Explorer.

You can create and set up a budget in two ways:
+ [Using a budget template (simplified)](budget-templates.md)
+ [Customizing a budget (advanced)](custom-budgets.md)

## Billing view prerequisites and monitoring
<a name="budget-billing-view"></a>

AWS Budgets supports billing views, allowing you to create and manage budgets based on filtered cost and usage data across multiple accounts within your organization. When creating a budget, you can select a billing view to define the scope of cost and usage data the budget will track. For more information on controlling access to cost management data using billing views, see [Controlling cost management data access with Billing View](https://docs.aws.amazon.com/cost-management/latest/userguide/billing-view.html).

**Note**  
AWS doesn't support billing transfer views for bill transfer accounts.

Before you use billing views with budgets, consider the following permissions requirements:
+ For cross-account billing views, the source account administrator must grant:
  + `budgets:ModifyBudget` permission on the billing view to allow target accounts/users to create budgets
  + `billing:GetBillingViewData` permission to access the billing view data
+ Target accounts/users also need:
  + `iam:CreateServiceLinkedRole` permission for the Budgets service principal (budgets.amazonaws.com):
+ The service-linked role monitors the health status of your billing view access:
  + `HEALTHY`: Indicates the budget has proper access to the billing view data
  + `UNHEALTHY`: Indicates the budget cannot access the billing view data, which might occur if permissions have been revoked or the view has been deleted. Reasons for unhealthy status can be:
    + `BILLING_VIEW_NO_ACCESS`: Indicates that access to the billing view associated with the budget has been removed (unshared) or the view was deleted.
    + `INVALID_FILTER`: Indicates that the budget's filter is invalid. This occurs when a management account becomes a linked account but has a budget that references an account outside their organization. In this situation, budget spend updates are paused.
