AWS Credits

AWS credits are applied to bills to help cover costs that are associated with eligible services. For more information about eligible services, see Redeem Your AWS Promotional Credit. Credits are applied until they are exhausted or they expire.

Applying AWS Credits

AWS applies credits in the following order:

  1. Soonest expiring

  2. Least number of applicable products

  3. Oldest credit

AWS applies the credit to the largest available charge across all eligible sellers of record. This means that AWS tries to apply your credits before they expire even if they use a more generic credit for a specific service.

For example, Jorge has two credits available to him. Credit one is for 10 dollars, expires January 2019, and can be used for either Amazon S3 or Amazon EC2. Credit two is for 5 dollars, expires December 2019, and can be used only for Amazon EC2. Jorge has two AWS charges: 100 dollars for Amazon EC2 and 50 dollars for Amazon S3. AWS applies credit one, which expires in January, to the Amazon EC2 charge, which leaves him with a 90-dollar Amazon EC2 charge and a 50-dollar Amazon S3 charge. AWS applies credit two to the remaining 90 dollars of Amazon EC2 usage, and Jorge has to pay 85 dollars for Amazon EC2 and 50 dollars for Amazon S3. All his credits are now exhausted.

Applying AWS Credits Across Single and Multiple Accounts

The following rules specify how AWS applies credits to bills for single accounts and for organizations:

  • The billing cycle begins on the first day of each month.

  • If an account is owned on the first day of the month by an individual who is not part of an organization but who later in the month joins one, AWS applies credits to that individual's bill for their usage from the first day of the month until the day that they join the organization.

  • If an account is owned on the first day of the month by an organization, AWS applies credits redeemed by the payer account or by any linked account to the organization's bill.

  • If an individual leaves an organization during the month, AWS begins applying credits to the single account on the first day of the following month.

For example, assume that Susan owns a single account on the first of the month and then joins an organization during the month. Also assume that she redeems her credits on any day after she joins the organization. AWS applies her credits to her account for usage she incurred from the first of the month to the day that she joined the organization. However, from the first of the following month onward, AWS applies the credits to the organization's bill. If Susan leaves the organization, any credits that she redeems are also applied to the organization's bill until the first of the month after her departure. On that day, AWS again applies Susan's credits to her bill.

If you're more comfortable with numbers, assume that Susan owns a single account on January 1 and joins an organization on January 11. If Susan redeems 100 dollars of credits on January 18, AWS applies them to her account for the usage that she incurred from January 1 to January 11. From February onward, Susan's credits are applied to the organization's consolidated bill. If Susan has 50 dollars of credits and leaves the organization on April 16, her credits are applied to the organization's consolidated bill for April. From May onward, Susan's credits are applied to her account.

Sharing AWS Credits

You can turn off credit sharing on the Preferences page on the Billing and Cost Management console. The following rules specify how credits are applied to bills for single accounts and for organizations when credit sharing is turned off:

  • The billing cycle begins on the first day of each month.

  • Credits are applied to only the account that received the credits.

  • Bills are calculated using the credit sharing preference that is active on the last day of the month.

  • In an organization, only the payer account can turn credit sharing off or on. The credit sharing preference applies to all accounts in an organization.
