# Creating a cost budget Use this procedure to create a budget that's based on your costs. **To create a cost budget** 1. Open the Billing and Cost Management console at [https://console.aws.amazon.com/cost-management/](https://console.aws.amazon.com/cost-management/). 1. In the navigation pane, choose **Budgets**. 1. At the top of the page, choose **Create budget**. 1. Under **Budget setup**, choose **Customize (advanced)**. 1. Under **Budget types**, choose **Cost budget**. Then, choose **Next**. 1. Under **Details**, for **Budget name**, enter the name of your budget. Your budget name must be unique within your account. It can contain A-Z, a-z, spaces, and the following characters: ``` _.:/=+-%@ ``` 1. Under **Set budget amount**, for **Period**, choose how often you want the budget to reset the actual and forecasted spend. + **Daily** for every day + **Monthly** for every month + **Quarterly** for every three months + **Annually** for every 12 months + **Custom** to specify your own start and end dates **Note** With a **Monthly** or **Quarterly** budget period, you can set future budgeted amounts using the budget planning feature. **Custom** period budgets align with time periods outside of standard reset options. For example, you can create a budget period that matches your fiscal year or project timeline. 1. For **Budget renewal type**, choose **Recurring budget** for a budget that resets after the budget period. Or, choose **Expiring budget** for a one-time budget that doesn't reset after the budget period. 1. Choose the start date or period to begin tracking against your budgeted amount. For an **Expiring budget**, choose the end date or period for the budget to end on. All budget times are in the UTC format. 1. For **Budgeting method**, select the way that you want your budget amount to be determined each budget period: + **Fixed**: Set one amount to monitor every budget period. + **Planned**: Set different amounts to monitor each budget period. + **Auto-adjusting**: Set your budget amount to be adjusted automatically based on your spending pattern over a time range that you specify. For more information about each method, see [Budget methods](budget-methods.md) 1. Enter your budgeted amount for the selected period. This is the value the budget will track against. 1. (Optional) Under **Budget scope**, for **Filters**, choose **Add filter** to apply one or more of the [available filters](budgets-create-filters.md). Your choice of budget type determines the set of filters that's displayed on the console. **Note** You can't use the **Linked account** filter within a linked account. 1.

Useful for organizations sharing commitment benefits. + **Use unblended costs**: View actual resource costs charged at time of usage. Suitable for individual account tracking. + **Use net unblended costs**: View actual costs after all discounts and credits are applied.

To be notified at 160 dollars (80% of your budget), enter **160** for an absolute budget or **80** for a percentage budget. Next to the amount, choose **Absolute value** to be notified when your costs exceed the threshold amount. Or, choose **% of budgeted amount** to be notified when your costs exceed the threshold percentage. Next to the threshold, choose **Actual** to create an alert for actual spend. Or, choose **Forecasted** to create an alert for forecasted spend. 1.
