Sustained Use Discounts

Automatic, usage-based savings for consistent Google Cloud workloads.

What is Sustained Use Discounts?

Sustained Use Discounts (SUDs) are an automatic cost-saving feature in Google Cloud Platform (GCP) that rewards customers for running eligible Compute Engine and Google Kubernetes Engine (GKE) resources consistently over the course of a billing month. When you use virtual machine (VM) instances or other eligible resources for more than 25% of the month, Google Cloud automatically applies incremental discounts to your resource costs—no manual intervention or upfront commitment is required.

The discount increases with the percentage of the month that your resources are running, reaching up to 30% off the base resource price when VMs are used for the entire month. Sustained Use Discounts are designed to help organizations optimize their cloud spend for long-running workloads, providing transparent and predictable savings directly on your monthly bill.
