When usage is spread across multiple subscriptions or fluctuates significantly (for example, development and test workloads that are frequently stopped and started), a narrowly scoped Savings Plan may not consistently find enough eligible usage to consume the full commitment. As a result, part of the committed hourly spend goes unused while other eligible workloads outside the scope continue to incur on-demand charges. Azure supports broader scoping options - such as Management Group or Shared scope - that allow the commitment to be applied across a larger pool of eligible compute. Selecting an overly restrictive scope can therefore directly drive underutilization, even when sufficient total usage exists across the enrollment or billing profile. ## Billing model The pricing dimensions that drive this cost. Azure Savings Plans apply a fixed hourly commitment against eligible compute usage within the configured scope. If eligible usage within that scope is insufficient or intermittent, part of the commitment remains unused while additional compute may still be billed at on-demand rates elsewhere. ## How to detect 4 checks to find it in your estate. - Review whether Savings Plan utilization remains consistently below full consumption over time - Assess whether eligible compute usage is distributed across multiple subscriptions or organizational boundaries - Identify patterns of fluctuating usage (such as non-production workloads) that may prevent steady commitment consumption within a narrow scope - Evaluate whether unused commitment coincides with eligible on-demand compute running outside the Savings Plan's scope ## How to fix 4 ways to remove the waste. - Broaden the Savings Plan scope to include additional eligible subscriptions where appropriate - Use Management Group scope when commitments should stay aligned to a specific line of business while still covering multiple subscriptions (it covers only subscriptions that are in both the management group and the enrollment or billing profile used to purchase the plan) - Use Shared scope when maximizing utilization across all eligible subscriptions in the EA enrollment or MCA billing profile is the primary objective - Reassess scope configuration whenever organizational structure or workload distribution changes ## Documentation Vendor references for pricing and configuration.
