AWS Credits

AWS credits are applied to bills to help cover costs associated with eligible services. For more information about eligible services, see Redeem Your AWS Promotional Credit. Credits are applied until they are exhausted or expire. The following rules specify how they are applied 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 1st by someone who is not part of an organization but who later in the month joins one, credits are applied to that person's bill for their usage from the 1st until the day they join the organization.

  • If an account is owned on the 1st by an organization, credits redeemed by the master account or by any member account are applied 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. Assume also 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 1st to the day she joined the organization. However, from the first of the following month on, AWS applies the credits to the organization's bill. If Susan leaves the organization, any credits she redeems are also applied to organization's bill until the first of the month following her departure. On that day, AWS again applies Susan's credits to her bill.

If you are 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 these to her account for the usage that she incurred from January 1 to January 11. From February on, 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 on, Susan's credits are applied to Susan's account.
