Spend-based committed use discounts

Spend-based committed use discounts (CUD) provide a discount in exchange for your commitment to spend a minimum amount for a service in a particular region. The discount applies to all of your vCPU and memory usage for the service.

Currently, spend-based CUDs are only available for limited products. To view them, see products covered by spend-based commitments.

You can purchase spend-based committed use discounts from your Cloud Billing account; they apply to eligible usage in any projects paid for by that Cloud Billing account.

Purchasing spend-based commitments

You can purchase spend-based committed use discounts in the Google Cloud Console. The commitments are effective starting within the hour from the time you purchased them. The discounts are applied to eligible usage in the region you specified.

Permissions required

If you accidentally purchased a commitment or made a mistake configuring your commitment, contact Cloud Billing Support for help.

How committed use discounts work

Your spend-based committed use discount is applied to the eligible usage each hour.

If you use more in the hour than you committed to, the overage is charged at your regular on-demand rate. If you use less in the hour than you committed to, you do not fully utilize your commitment or realize your full discount.
