# Getting started with rightsizing recommendations
<a name="rr-getting-started"></a>

You can access your reservation recommendations and resource-based recommendations in the Billing and Cost Management console. After you enable the feature, it can take up to 24 hours to generate your recommendations.

**To enable and access rightsizing recommendations**

1. Open the Billing and Cost Management console at [https://console.aws.amazon.com/costmanagement/](https://console.aws.amazon.com/costmanagement/).

1. In the navigation pane, choose **Cost Management preferences**.

1. On the **Preferences** page, under **Rightsizing - *legacy*** in the **General** tab, select **Enable Rightsizing recommendations**.

1. Choose **Save preferences**.
**Note**  
Only regular or a management account can enable rightsizing recommendations. After you enable the feature, both member and management account can access rightsizing recommendations unless the management account specifically prohibits member account access on the **settings** page.   
To improve the recommendation quality, AWS might use your published utilization metrics, such as disk or memory utilization, to improve our recommendation models and algorithms. All metrics are anonymized and aggregated before AWS uses them for model training. If you want to opt out of this experience and request that your metrics not be stored and used for model improvement, contact AWS Support. For more information, see [AWS Service Terms](https://aws.amazon.com/service-terms/).
