I purchased Savings Plans, but I'm not getting the result that I expected.
Resolution
Meet the requirements
For your Savings Plans to apply, you must meet the following requirements:
- The upfront costs for your Savings Plans must successfully process. Check the status of your payments on the Payment History page of the AWS Billing and Cost Management console. You can't retry a failed Savings Plan purchase.
- Your Savings Plans must still be active. After your term expires, AWS bills your usage at the On-Demand Instance price. To continue to receive the savings, purchase another Savings Plan with the same specifications. Use the AWS Cost Management console to check if your Savings Plans are active.
- Your AWS compute usage must be for a supported service that has a corresponding Savings Plans type. Amazon Elastic Compute Cloud (Amazon EC2), AWS Fargate, AWS Lambda, or Amazon SageMaker are eligible services for Savings Plans.
To avoid gaps in savings, see Managing your Savings Plans alerts.
Analyze your usage
Use AWS Cost Explorer to analyze the costs and usage that are associated with your Savings Plans. You can also use the Savings Plans performance reports in Cost Explorer to determine whether you're optimizing your Savings Plans.
Understand your Savings Plans
The following scenarios explain how your Savings Plans work.
Savings Plans commitment
When there's eligible usage, Savings Plans apply up to an hourly commitment for each hour. Because Savings Plans are hourly, you might have a remaining Savings Plans commitment in some hours and additional On-Demand charges in other hours. You can't apply the remaining Savings Plans commitment in one hour to On-Demand charges in another hour.
Reserved Instances
If you have Reserved Instances (RI) and Savings Plans, RIs apply before Savings Plans. Savings Plans cover uncovered On-Demand usage.
On-Demand charges
When Savings Plans apply to usage, AWS billing shows the On-Demand charges first and then a corresponding discount for the On-Demand usage. AWS applies Savings Plans to the qualifying usage that receives the largest calculated savings. If other usage provides a larger savings, then AWS applies the Savings Plans to that usage.
Free Tier benefits
AWS applies AWS Free Tier benefits before Savings Plans benefits. Savings Plans cover excess usage that Free Tier doesn't cover.
Multiple Savings Plans
If multiple Savings Plans are active at the same time, then AWS generates your bill based on all active Savings Plans.
Savings Plans applied usage
AWS applies Savings Plans benefits to usage every hour. If you don't use all the benefits, then AWS doesn't apply them to the next hour.
Organizations account Savings Plans
AWS applies Savings Plans differently in the consolidated bill of an AWS Organization's organization depending on whether you turned sharing on or off. For more information, see How is the pricing benefit of a Savings Plan applied across an organization's consolidated bill?
