# Understanding Savings Plans
<a name="cur-sp"></a>

You can use Cost and Usage Reports (AWS CUR) to track your Savings Plans utilization, charges, and allocations.

## Savings Plans line items
<a name="cur-sp-lineitems"></a>

Savings Plans provide a flexible pricing model that offers low prices on Amazon EC2, AWS Fargate, AWS Lambda, and Amazon SageMaker AI in exchange for a commitment to a consistent amount of usage (measured in \$1/hour) for a 1-year or 3-year term.

The following line items in AWS CUR help you track and manage your spend with Savings Plans. 

**Note**  
In the following tables, the columns and rows from AWS CUR are transposed for clarity. The values in the first column represent the headers of a report. These examples include only a few key AWS CUR columns. To learn more about other AWS CUR columns, see the [Data dictionary](data-dictionary.md).

**Upfront fee**  
The **SavingsPlanUpfrontFee** line item is added to your bill when you purchase an `All Upfront` or `Partial Upfront` Savings Plans. The following table shows how this one-time fee appears in some AWS CUR columns.      
[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/cur/latest/userguide/cur-sp.html)

 **Savings Plans recurring monthly fee**  
The **SavingsPlanRecurringFee** line item describes the recurring hourly charges that correspond to `No Upfront` or `Partial Upfront` Savings Plans. Initially, the **SavingsPlanRecurringFee** is added to your bill on the day of purchase and hourly thereafter.  
The **SavingsPlanRecurringFee** allocated to the hour (applicable to Hourly cost and usage) or day (applicable to Daily cost and usage) is added to your bill at the hour of purchase. It is added every hour/day of the billing period subsequently.  
For an `All Upfront` Savings Plans, the line item indicates the portion of the Savings Plans unused during the billing period.  
The following table shows how the recurring hourly charges appear in some AWS CUR columns.

The SavingsPlanRecurringFee is calculated differently than the recurring RI fee. The recurring RI fee is a monthly charge while the SavingsPlanRecurringFee is an hourly charge. For information on the recurring RI fee, see [Recurring monthly RI fee](regular-reserved-instances.md#recurring-monthly).

**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 Plans 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 AWS CUR columns.  
      
[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/cur/latest/userguide/cur-sp.html)
When you have more usage than your Savings Plans commitment can cover, your uncovered usage still appears as a Usage Line Item and the covered usage appears as **SavingsPlanCoveredUsage** with the corresponding **SavingsPlanNegation** line items.
