This topic describes how to query savings plan usage and coverage metrics and use them to optimize your plan configuration.
Query savings plan usage
What is savings plan usage?
Usage reflects the extent to which your savings plan is utilized. A high usage rate indicates that your committed consumption is being used efficiently.
Formula: Savings plan usage = Deducted amount / Total amount (savings plan)
Deducted amount: The actual amount of pay-as-you-go bills offset by the savings plan during a specific period.
Total amount (savings plan): The total amount of the committed consumption for a specific period, calculated as: Hourly commitment × Total hours in the period.
The Saved Amount displayed in the console represents your net cost savings (deducted amount minus the cost of the plan). For the purpose of calculating usage and coverage, ensure that you use the deducted amount, which reflects the total gross bill value covered by the plan.
Example scenario
You purchase a 3-year, all-upfront, general-purpose savings plan. From October 1, 2025, to December 31, 2025, the total amount (savings plan) is USD 160.80, and the deducted amount is USD127.41.
Usage = 127.41 / 160.80 = 79.24%.
This indicates that, while the savings plan was applied to offset costs, approximately 20% of the committed quota remains unused. Consider adjusting your resource strategy to improve the utilization rate.
You can query your savings plan usage in the following ways:
Console
On the Expenses and Costs console, navigate to Billing Account > Savings Plan.
Switch to the Usage tab. In the panel on the right, query usage data by Time Dimension or by setting Filters.
Time Dimension: Supports queries by Hour, Day, or Month. Hourly data is available for the last 30 days, daily data for the last 90 days, and monthly data for the last 18 months.
Filters: To query the usage of specific resources, filter by criteria such as Type and Region.
Query by Budget: Create a Usage or coverage budget on the Budgets page to query usage based on that budget. For more information, see Budget Management.
After you set the search criteria, the page displays overall data such as Expected Amount, Total Amount (Savings Plan), and Saved Amount. Below, you can query the Usage trend and Usage Details to help you analyze your overall usage.
Legacy console
On the Expenses and Costs console, navigate to Savings Plan > Overview.
Switch to the Usage tab. Query usage data by Time Range or by adding Search Conditions.
Time Unit: Supports queries by Hour, Day, or Month. Hourly data is available for the last 30 days, daily data for the last 90 days, and monthly data for the last 18 months.
Search Conditions: To query the usage of specific resources, filter by criteria such as Account and Type.
After you set the search criteria, the page displays overall data such as Expected Amount, Total Amount (Savings Plan), and Saved Amount. Below, you can query the Usage trend and Usage Details to help you analyze your overall usage.
OpenAPI
Query usage using the following API operations.
API operation | Description |
Queries the summary of savings plan usage. | |
Queries the details of savings plan usage. |
Usage data becomes final and accurate three days after the billing cycle (T+3).
The Usage tab does not display data for total-amount savings plans; this information is available on the Overview tab of the Savings Plan page.
Query savings plan coverage
What is savings plan coverage?
Coverage reflects the percentage of your pay-as-you-go resource spending that is offset by your savings plan. A higher coverage rate indicates that a larger proportion of your eligible resource costs is being offset by the savings plan.
Formula: Savings plan coverage = Deducted amount / Total spending on eligible resources
Deducted amount: The pay-as-you-go amount actually offset by the savings plan.
Total spending on eligible resources: Total amount (savings plan) + pay-as-you-go amount exceeding the commitment.
The total spending on eligible resources is not a single value displayed in the UI. It is calculated by adding your total amount (savings plan) to the amount you paid for eligible resources that exceeded your plan's commitment.
To see the total potential for savings, refer to the expected amount (pay-as-you-go amount at normal rates) on the Overview tab.
Example scenario
You purchase a 3-year, all-upfront, general-purpose savings plan. From October 1, 2025, to December 31, 2025, the deducted amount is USD 1.23, and the total spending on eligible resources is USD 1.23.
Coverage = 1.23 / 1.23 = 100%.
This means that the savings plan completely covered the spending on eligible pay-as-you-go resources, achieving optimal cost savings.
Query your savings plan coverage in the following ways:
Console
On the Expenses and Costs console, navigate to Billing Account > Savings Plan.
Switch to the Coverage tab. Query coverage data using the following criteria or by setting Filters.
Time Dimension: Supports queries by Hour, Day, or Month. Hourly data is available for the last 30 days, daily data for the last 90 days, and monthly data for the last 18 months.
Filters: To query the coverage of specific instances, filter by criteria such as Type and Region.
Query by Budget: Create a Usage or coverage budget on the Budgets page to query coverage based on that budget. For more information, see Budget Management.
By shared account: If you share your savings plan with multiple accounts, select an account to query its coverage.
After you set the search criteria, the page displays overall data such as Total Coverage (%) and Deducted Amount. Below, you can query the Coverage trend and Coverage Details.
On the Expenses and Costs console, navigate to Savings Plan > Overview.
Switch to the Coverage tab. Query coverage data by Time Range or by adding Search Conditions.
Time Unit: Supports queries by Hour, Day, or Month. Hourly data is available for the last 30 days, daily data for the last 90 days, and monthly data for the last 18 months.
Search Conditions: To query the coverage of specific instances, filter by criteria such as Account and Type.
Query by Budget: Create a Usage or coverage budget to query coverage based on that budget. For more information, see Budget Management.
After you set the search conditions, the page displays overall data such as Expected Amount, Total Amount (Savings Plan), and Saved Amount. Below, you can query the Coverage trend and Coverage Details to help you analyze your overall coverage.

The Coverage tab does not display data for total-amount savings plans; this information is available on the Overview tab.
Optimize your savings plan based on usage and coverage
Analyze both usage and coverage to make informed decisions about your savings plan commitment.
Usage | Coverage | Analysis | Recommendation |
High | High | You have an appropriate savings plan commitment and are effectively saving on costs. | Maintain your current configuration and perform regular reviews. |
High | Low | Your savings plan is highly utilized, but there is still significant pay-as-you-go spending that could be covered. | Consider increasing your savings plan commitment to further reduce costs. |
Low | High | The savings plan is underutilized, showing a significant gap between the total amount (savings plan) and actual pay-as-you-go spending. | Consider reducing your savings plan commitment or purchasing a different type of savings plan that better fits your business needs. |
Low | Low | A mismatch between your plan and your actual resource usage is resulting in wasted commitment and missed savings. | Adjust your resource usage strategy and instance types to prioritize using the savings plan to cover pay-as-you-go bills. |
For resources using Auto Scaling, achieving 100% coverage is often not the most cost-effective strategy. Because resource demand fluctuates, aiming for lower coverage helps avoid wasted commitment during off-peak periods. Use the Savings Plan Purchase Recommendation tool to determine the optimal balance between coverage and usage for your elastic workloads.
