Effective Savings Rate
Effective Savings Rate (ESR) is a FinOps standard metric that measures the actual ROI of various cloud rate optimization efforts, including discount instruments, private rates, and Spot VMs or Instances. ESR serves as a key objective indicator of success for understanding cloud cost and rate optimization.

About Effective Savings Rate
ESR is a metric cloud FinOps teams can use to measure their actual savings rate, or the discount they are receiving on the list price for cloud services from using commitments, such as AWS Savings Plans, Reserved Instances, Google Cloud Committed Use Discounts, Azure Reservations and Savings Plans, private rates, and Spot VMs or Instances.
How to Calculate your ESR
Cloud Savings Generated
The amount of dollars your organization saved on cloud costs. Cloud savings can be generated from various rate optimization strategies like using cloud discount instruments, private rates, or Spot VMs and Instances.
On-Demand Equivalent (ODE) Spend
The amount your organization would have paid to the cloud provider if no discounts were applied. Think of this as the list price or on-demand rate for cloud services.
Components of ESR
Traditional performance metrics used to measure cloud savings are very limited. For example, cloud cost optimization benchmarks for coverage and utilization measure just two dimensions of a multidimensional environment. ESR however takes into account commitment coverage, utilization, and discount rate, Spot VMs and Instances, and discounts from private rates to provide a more accurate calculation of your ROI.
Coverage
The percentage of cloud resources “covered” with a discount instrument, private discounts, or Spot VMs and Instances in your environment.
Utilization
The percentage of discount commitments being “used” to reduce the cost of your cloud resources.
Discount Rate
The percentage off the on-demand or “list price” of cloud resources you are receiving across every cloud resource in your environment.
When you calculate Effective Savings Rate, it is important to factor in all three components to truly understand the ROI you’re receiving from the use of discount instruments across services like AWS Reserved Instances and Savings Plans, Google Cloud Committed Use Discounts, private rates, Azure Reservations and Savings Plans, and Spot VMs or Instances.
