Committed use discounts

Committed use discounts (CUDs) for Cloud Run provide deeply discounted prices in exchange for committing to continuously use Cloud Run in a particular region for a one year term.

Cloud Run committed use discounts are ideal for workloads with predictable resource needs. You commit to a consistent amount of usage, measured in dollars per hour of equivalent on-demand spend, for a one-year term. In exchange, you receive a discounted rate on the applicable usage your commitment covers.

You can purchase committed use discounts from any Cloud Billing account, and the discount applies to any eligible usage in projects paid for by that Cloud Billing account:

  • Any overage is charged at the on-demand rate.
  • When you purchase a Cloud Run committed use discount, you pay the same commitment fee for the entirety of the commitment term, even if the price of applicable usage changes.
  • You still receive the same discount percentage on applicable usage in the event of a price change.
  • The commitment fee is billed monthly.

Calculating hourly on-demand commitment

You calculate the baseline per hour cost of CPU + Memory + requests across all services in the region you want to benefit from a committed use discount. Any usage above that limit will be charged at the regular on-demand price.

Once you make the commitment, you're charged that amount even if you decide to stop or scale down your Cloud Run usage during the rest of the commitment period.

Example

  • You commit to spend $1 per hour on Cloud Run for one year in us-central1 across all projects.

  • You are charged a minimum of $1 * 83% = $0.83 per hour for the whole year, independently from actual usage.

  • If, in a given hour, Cloud Run usage inus-central1 before the discount is $1.50, then you pay only 1 * 83% + (1.50 - 1) = $1.33.

Recommendations

When making the decision on whether to purchase committed use discounts, keep in mind that commitments are purchased across all projects of the billing account.
