This page describes how committed use discounts work with Backup for GKE.
Committed use discounts (CUDs) for Backup for GKE provide discounted prices in exchange for committing to continuously use Backup for GKE in a particular region for a one- or three-year term.
Backup for GKE CUDs are ideal for workloads with predictable resource needs. You commit to a consistent amount of usage, measured in $ per hour of equivalent on-demand spend, for a one- or three-year term. In exchange, you receive a discounted rate on the applicable usage your commitment covers.
CUDs pricing applies only to backup management, that is Pods per plan. Pricing doesn't apply to backup storage (GiB) or inter-region data transfer (GiB).

Calculate your hourly on-demand commitment
You can calculate your hourly on-demand commitment based on the baseline cost of backup management, that is Pods per plan, for all your backup plans in a specific region that you want to benefit from a committed use discount. Any usage beyond that limit incurs the regular on-demand price.
As an example, consider a single backup plan in Iowa (us-central1) backs up
around 1,000 Pods in a month in Iowa and you are interested in purchasing a
one-year-committed-use discount.
From the pricing table, the total hourly commitment cost in a region is calculated as:
Backup management (Pods per plan): 1,000 * $0.00137 per Pod per hour = $1.37 per hour in committed use hourly pricing.
The monthly cost is calculated based on 720 hours in a month:
- On-demand pricing = $1.37 per hour * 720 hours = $986.4 per month
- After a 20% 1-year CUD discount = $789.1 per month
- Total savings of $197.3 per month
After you make the commitment, you're charged that amount even if you decide to stop or scale down the actual number of Pods protected.
