Reserved Instances and Savings Plans discount sharing
The management account of an organization can deactivate Reserved Instance discount and Savings Plans discount sharing for any accounts in that organization, including the management account. This means that Reserved Instances and Savings Plans discounts aren't shared between any accounts that have deactivated sharing.
To share an Reserved Instance or Savings Plans discount with an account, both accounts must have sharing activated. You can change your preference at any time. Each estimated bill is computed by using the last set of preferences. The final bill for the month is calculated based on the preferences set at 23:59:59 UTC time on the last day of the month.
If Savings Plans sharing is turned on for an AWS Organizations account, then it must meet the following criteria:
At least one account in the consolidated billing family must have AWS compute usage for the Savings Plans to apply to the management account's bill.
Savings Plans first apply usage in the purchasing account. If there are any unused hourly commitments, the Savings Plans automatically applies them to other accounts in the organization that have sharing turned on. Accounts with the largest calculated savings are prioritized.
To apply discounts to other eligible linked accounts, the Savings Plans opener account must be included and activated under the RI and Savings Plans discount sharing preferences.
If the Savings Plans owner account is removed or deactivated from the sharing preferences, the Savings Plans discount no longer applies to the other eligible linked accounts.
If a Savings Plans owner member account leaves or is removed from the organization, the Savings Plans no longer apply to the consolidated bill.
Important
Deactivating Reserved Instance and Savings Plans discount sharing can result in a higher monthly bill.
To share the Savings Plans discount, the Savings Plans owner account must be active in the RI and Savings Plans discount sharing preferences. This enables the discount usage across other eligible linked accounts in the organization.
