Understanding Savings Plans
You can use Cost and Usage Reports (Amazon CUR) to track your Savings Plans utilization, charges, and allocations.
Savings Plans line items
Savings Plans provide a flexible pricing model that offers low prices on Amazon EC2, Amazon Fargate, Amazon Lambda, and Amazon SageMaker in exchange for a commitment to a consistent amount of usage (measured in $/hour) for a 1-year or 3-year term.
The following line items in Amazon CUR help you track and manage your spend with Savings Plans.
Note
In the following tables, the columns and rows from Amazon CUR are transposed for clarity. The values in the first column represent the headers of a report. These examples include only a few key Amazon CUR columns. To learn more about other Amazon CUR columns, see the Data dictionary.

- Savings Plans discount benefits
-
The SavingsPlanCoveredUsage line item describes the instance usage that received Savings Plans benefits. A SavingsPlanCoveredUsage line item shows an unblended cost of what the On-Demand charge would have been without the Savings Plan benefit. This unblended cost is offset by the corresponding SavingsPlanNegation line item.
In each SavingsPlanCoveredUsage line item, you can see how that usage was billed against your Savings Plans hourly commitment by using the savingsPlan/SavingsPlanRate and savingsPlan/SavingsPlanEffectiveCost fields.
You'll see a corresponding SavingsPlanNegation for each SavingsPlanCoveredUsage line item. SavingsPlanNegation line items offset the unblended cost of SavingsPlanCoveredUsage, and grouped at the hourly level by SavingsPlanARN, Operation, Usage Type, and Availability Zone. Therefore, one SavingsPlanNegation line item might correspond to multiple SavingsPlanCoveredUsage line items.
The following table shows how the covered usage and the negation line items appear in some Amazon CUR columns.
