AWS Credits

AWS credits are credits that you can apply to your account to cover the costs associated with eligible AWS services. AWS applies the credits to your bill until the credits are exhausted or expire. For more information about eligible services, see Redeem Your AWS Promotional Credit.

To give the owner of the organization's master account the lowest bill, any AWS credits redeemed by the master account and member accounts are applied to the consolidated bill. Credits can apply to only one account per billing cycle. The following rules determine which account AWS credits are applied to:

  • If the credits are redeemed during a billing period, they are applied to the bill that belongs to the account that was paying at the start of the month. If the credits are redeemed and the account was a single account at the start of the month, the credits are applied to the single account bill for that billing period. If the credits are redeemed and the account was a member of an organization at the start of the month, the credits are applied to the organization's consolidated bill for that billing period.

  • If the credits were redeemed before a billing period starts, the credits are applied to the bill that belongs to the account that was paying at the beginning of the billing period.

For example, if Susan joins an organization on January 15 and redeems 100 dollars of credit on January 18, Susan's credits are applied to her account for the usage incurred from Jan 1 through January 15. From February on, Susan's credits are applied to the organization's consolidated bill. If Susan has 50 dollars of credit and leaves the organization on April 16, Susan's credits are applied to the organization's consolidated bill for April. From May on, Susan's credits are applied to Susan's account.
