Monitor your savings plan performance by tracking two complementary metrics: usage and coverage. Together, they show whether your commitment is fully utilized and how much of your eligible pay-as-you-go spending is protected by the plan.
Savings plan usage
Usage measures how much of your committed quota is actually consumed. A high usage rate means your commitment is working efficiently.
Formula: Usage = Deducted amount ÷ Total amount (savings plan)
| Term | Definition |
|---|---|
| Deducted amount | The pay-as-you-go bill amount offset by the savings plan during a specific period |
| Total amount (savings plan)USDUSDUSDUSD | Hourly commitment × Total hours in the period |
The Saved Amount shown in the console is your net cost savings (deducted amount minus the cost of the plan). For usage and coverage calculations, use the deducted amount, which reflects the total gross bill value covered by the plan.
Example
For a 3-year, all-upfront, general-purpose savings plan covering October 1–December 31, 2025:
Total amount (savings plan): USD 160.80
Deducted amount: USD 127.41
Usage = 127.41 ÷ 160.80 = 79.24%
About 20% of the committed quota went unused. Adjust your resource strategy to improve the usage rate.
Query usage
Console
In the Expenses and Costs console, go to Expenses and CostsExpenses and CostsBilling Account > Savings Plan.
Click the Usage tab. Filter and query usage data using the following options:
Option Description Time Dimension View data by Hour, Day, or Month. Hourly data covers the last 30 days, daily data covers the last 90 days, and monthly data covers the last 18 months. Filters Narrow results by Type, Region, and other criteria to focus on specific resources. Query by Budget Link a Usage or coverage budget from the Budgets page to filter usage by that budget. For details, see Budget Management. The page displays summary metrics including Expected Amount, Total Amount (Savings Plan), and Saved Amount, followed by a Usage trend chart and Usage Details table.
Usage data becomes final three days after the billing cycle (T+3). The Usage tab does not display data for total-amount savings plans; view that information on the Overview tab of the Savings Plan page.
In the Expenses and Costs console, go to Savings Plan > Overview.
Click the Usage tab. Filter and query usage data using the following options:
Option Description Time Unit View data by Hour, Day, or Month. Hourly data covers the last 30 days, daily data covers the last 90 days, and monthly data covers the last 18 months. Search Conditions Narrow results by Account, Type, and other criteria to focus on specific resources.

Savings plan coverage
Coverage measures what percentage of your eligible pay-as-you-go spending is offset by the savings plan. A high coverage rate means the plan protects a large share of your eligible resource costs.
Formula: Coverage = Deducted amount ÷ Total spending on eligible resources
| Term | Definition |
|---|---|
| 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 spending that exceeded the commitment |
Total spending on eligible resources is not a single value in the console. Calculate it by adding Total Amount (Savings Plan) to the pay-as-you-go amount for eligible resources that exceeded your plan's commitment. To see your full potential for savings, check Expected Amount (the equivalent pay-as-you-go cost at normal rates) on the Overview tab.
Example
For a 3-year, all-upfront, general-purpose savings plan covering October 1–December 31, 2025:
Deducted amount: USD 1.23
Total spending on eligible resources: USD 1.23
Coverage = 1.23 ÷ 1.23 = 100%
The savings plan completely covered all eligible pay-as-you-go spending during this period.
Query coverage
Console
In the Expenses and Costs console, go to Billing Account > Savings Plan.
Click the Coverage tab. Filter and query coverage data using the following options:
Option Description Time Dimension View data by Hour, Day, or Month. Hourly data covers the last 30 days, daily data covers the last 90 days, and monthly data covers the last 18 months. Filters Narrow results by Type, Region, and other criteria to focus on specific instances. Query by Budget Link a Usage or coverage budget from the Budgets page to filter coverage by that budget. For details, see Budget Management. By shared account If you share your savings plan across multiple accounts, select an account to view its coverage. The page displays summary metrics including Total Coverage (%) and Deducted Amount, followed by a Coverage trend chart and Coverage Details table.
Coverage data becomes final three days after the billing cycle (T+3). The Coverage tab does not display data for total-amount savings plans; view that information on the Overview tab.

Optimize your commitment based on usage and coverage
Analyze both metrics together to decide whether to adjust your savings plan commitment.
| Usage | Coverage | What it means | Action |
|---|---|---|---|
| High | High | Your commitment is sized correctly and delivering strong savings. | Maintain the current configuration and review periodically. |
| High | Low | The plan is fully utilized, but significant pay-as-you-go spending remains uncovered. | Increase your savings plan commitment to extend coverage. |
| Low | High | The plan covers most eligible spending, but the commitment exceeds your actual usage. | Reduce your commitment or switch to a savings plan type that better fits your workload. |
| Low | Low | A mismatch between your plan and your resource usage is wasting commitment and missing savings. | Shift resource usage to prioritize savings plan coverage, and review your instance types. |
For workloads using Auto Scaling, 100% coverage is often not the most cost-effective target. Because demand fluctuates, a lower coverage rate helps avoid unused commitment during off-peak periods. Use the Savings Plan Purchase Recommendation tool tool to find the optimal balance between coverage and usage for elastic workloads.
