Learn how to monitor and control your Azure spending and optimize the use of Azure resources.
How do I manage Azure savings plan billing?
Microsoft introduced an Azure savings plan for compute services. This plan enables customers to save money by committing to an hourly spend on Azure compute services for either one or three years. To ensure your plan aligns with actual usage and costs, Partner Center now provides streamlined invoice and reconciliation line items. The daily rated usage data model is updated with new attributes to make the reconciliation process easier and faster.
| File | New column | Description |
|---|---|---|
| Daily rated usage reconciliation (closed and open periods) | BenefitId |
Unique identifier for each Azure savings plan. |
BenefitOrderId |
Links daily charges to monthly costs (matches ReservationOrderId in the invoice reconciliation). |
|
BenefitType |
To isolate savings plan charges, filter with SavingsPlan. |
| API | New attribute | Description |
|---|---|---|
| Billed and unbilled daily rated usage reconciliation API v2 (GA) | BenefitId |
Unique identifier for each Azure Savings Plan. |
BenefitOrderId |
Links daily charges to monthly costs (matches ReservationOrderId in the invoice reconciliation). |
|
BenefitType |
To isolate savings plan charges, filter with SavingsPlan. |
To identify Azure savings plan charges, follow these steps:
- In your daily rated usage reconciliation line items, filter the
BenefitTypefield by "SavingsPlan." - These line items show zero charges in the
BillingPreTaxTotalfield since savings plan discounts are applied to them.
To find out the cost efficiency, follow these steps:
- Match identifiers:
- Link the
BenefitOrderId(from daily rated usage line items) with theReservationOrderId(in invoice reconciliation line items). - Cross-reference these IDs in your reports to align daily consumption with monthly savings plan costs.
- Link the
- Calculate savings:
- Pay-as-you-go charges reflect standard rates without discounts.
- Compare pay-as-you-go costs to your savings plan rates to quantify your savings.
Suġġeriment
Use only designated attributes: Rely on only BenefitOrderId and BenefitType to track savings plan details—other fields might not provide accurate matches.
Importanti
Partner earned credit (PEC) exclusion: PEC doesn't apply to usage eligible for savings plans.
To see the daily usage of your Azure savings plan in the Azure portal:
- Go to your customer view.
- Select the savings plan you bought to check how much you used it in the last week, month, quarter, or any date range.
To monitor how well your savings plan matches actual usage, use the Azure portal's "Utilization over time" feature. Follow these steps to adjust charges and maximize value:
- Step 1: Identify underutilized plans: To avoid <100% spending, filter plans with less than 100% utilization using
BenefitOrderId. - Step 2: Map covered resources: To ensure resources are correctly aligned with your plan's scope, check the
ResourceURIin daily usage line items. - Step 3: Verify daily coverage: To confirm resources incur no daily charges under the savings plan, sort daily usage data by
UsageDateand look forBenefitType = "SavingsPlan". - Step 4: Find overcommitments: To catch overages early and adjust usage or plans, check for
BenefitType = "Charge".
To see the effective rate of a savings plan, you can either:
- Check amortized data in the Azure portal's.
- Follow the calculation steps.
To understand your savings plan usage, review the amortized data for your subscription, resource group, or specific resource.
To download the amortized data, use the instructions provided in the export cost data with an Azure Storage account SAS key.
- Once downloaded, identify the savings plan's
resourceIdin the data. These attributes are different from the Partner Center daily rated usage data. See the attribute mapping table for the mapping. This mapping ensures you correctly interpret the data and avoid any confusion. - To make it easier, sort or filter the transactions by date to quickly find the relevant charges. Check the charges for the resources. If the
pricingModelis "SavingsPlan," it means there's no charge. - Review the
effectivePriceandcostInBillingCurrencyfor the effective rate and charges. - To find out the unused hours in your Azure savings plan:
- Filter by
productOrderIdto find the order ID. - Look for the
chargeTypelabeled "UnusedBenefits" to see any unused benefits in your plan. - Check the
quantityvalue. If the value is more than zero, it means there are unused hours for that day. This quantity shows how much of your savings plan is still unused.

Here's an example of how much you can save with our hourly savings plan, designed to offer significant discounts compared to pay-as-you-go rates:
Example
- If you buy a savings plan at $0.1/hour, you're billed this amount first for the hours it covers instead of the pay-as-you-go rate of $0.3264/hour for the VM, due to the discount.
- This commitment translates to savings of $0.2264/hour, which is approximately 69% discount.
- Moreover, by committing to a year, you receive an extra discount of 31.43%, paying only $0.22381248/hour.

Calculation of savings
- The savings plan covers
0.10 (A) ÷ 0.22381248 (C)hours per hour of VM usage, which is 0.446802609 (S) hours. - Every hour the VM runs, the savings plan covers
0.1 (A) ÷ 0.22381248 (C)hours per hour of VM usage, which is 0.446802609 (S) hours. For the remaining 0.553197391 (P) hours, you pay the pay-as-you-go rate of $0.180563628 (J), or0.553197391 (P) x 0.3264 (B).
Overall cost
- You're billed $0.280563628 (K) per hour, which includes $0.10 (A) for the savings plan and $0.180563628 (J) for the usage exceeding the savings plan commitment.
- Running the VM for 24 hours results in a daily cost of $6.733527082 (L), based on 24 hours multiplied by $0.280563628 (K). This cost includes both the savings plan rate and the pay-as-you-go rate for usage exceeding the savings plan commitment.

Calculations
Step 1: Determine savings plan quantity (S)
Formula: S = A ÷ C
Calculation: 0.1 ÷ 0.22381248 = 0.446802609
| Variable | Description | Calculation | Value |
|---|---|---|---|
| S | Savings plan quantity | A ÷ C | 0.446802609 |
Step 2: Determine pay-as-you-go quantity (P)
Formula: P = 1 - S
Calculation: 1 - 0.446802609 = 0.553197391
| Variable | Description | Calculation | Value |
|---|---|---|---|
| P | Pay-as-you-go quantity | 1 – S | 0.553197391 |
Step 3: Calculate daily hours distribution
Formula: F = E x S, G = E – F
Calculations:
Savings plan hours = 24 x 0.446802609 = 10.72326262
Pay-as-you-go hours = 24 – 10.72326262 = 13.27673738
| Variable | Description | Calculation | Value |
|---|---|---|---|
| F | Savings plan hours | E x S | 10.72326262 |
| G | Pay-as-you-go hours | E – F | 13.27673738 |

L = 0.280563628 x 24 = 6.733527082
| Variable | Description | Calculation | Value |
|---|---|---|---|
| L | Total cost per day | K x E | 6.733527082 |
Step 7: Calculate total savings (N)
Formula: N = M - L
Calculation: 7.8336 - 6.733527082 = 0.11000736
| Variable | Description | Calculation | Value |
|---|---|---|---|
| N | Savings amount | M - L | 1.100072918 |
| Savings percentage | (N ÷ M) x 100 | 14.04% |
Results summary
By utilizing the savings plan, the effective cost for 24 hours of VM usage is reduced from $7.8336 (pay-as-you-go) to $6.733527082, resulting in:
- Savings amount: $1.100072918
- Savings percentage: 14.04%
