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, AWS Reserved Instances, and GCP Committed Use Discounts.
How to calculate your ESR
Cloud Savings Generated
The amount of dollars your organization saved on cloud costs. Cloud savings may be generated from rate, usage, or other cloud cost optimization strategies.
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
Typical FinOps metrics used to measure savings performance from cloud cost optimizations, like coverage and utilization, are limited. Coverage and utilization together only measure two dimensions of a multidimensional formula. ESR takes into account commitment coverage, utilization, and discount rate to provide an accurate calculation of your ROI.
Coverage
The percentage of cloud resources “covered” with a discount instrument in your environment.
Utilization
The percentage of your 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 of these components to truly understand the ROI you’re receiving from the use of discount instruments, such as AWS Reserved Instances, AWS Savings Plans, and GCP Committed Use Discounts.
