For resource-based committed use discounts (CUDs), the default value of CUD scope for most Cloud Billing accounts has changed from Project to Billing account. If the CUD scope is set to Billing account, then resource-based CUDs from a commitment are shared across all projects in that account. If the CUD scope is set to Project, then resource-based CUDs from a commitment are available to only the project in which you purchased that commitment.

Depending on the Cloud Billing account's creation date and the active commitments in that account, this change applies in the following way:

• Cloud Billing accounts created on or after June 16, 2026: The CUD scope is Billing account (CUD sharing enabled) by default. • Cloud Billing accounts created before June 16, 2026:

If the account has no active resource-based commitments on June 16, 2026, then the CUD scope has changed to Billing account (CUD sharing enabled). • If the account has any active resource-based commitments on June 16, 2026, then the CUD scope remains unchanged and Google Cloud continues to use your existing configuration.
