Unexpected High Cost for Dataflows Standard Compute Despite Using Reserved F32 Capacity

Hi Parthiban006,

Coming to your "Has this separate billing for Dataflows Gen2 always been around, or is it new?" query, Dataflows Gen2 has always been billed separately from reserved Fabric capacity (F-SKUs). It’s not a recent change but it’s simply how the model has worked from the start, even if that wasn’t always obvious in pricing summaries or calculators.

Kindly go through the below links to get a better understanding of how Dataflow is billed.

Now coming to "Why doesn't the Azure Pricing Calculator or most Microsoft docs explicitly show this?" query, You’re right most documentation focuses on general Compute and Storage for Fabric, without clearly calling out that Dataflow Gen2 incurs its own compute charges. 

I suggest you to go through a official Microsoft source "Fabric Operations” which shows the billing meter used for Dataflow Gen2. Under the Data Factory section, it lists "Dataflow Gen2 Refresh -> billed via “Dataflows Standard Compute Capacity Usage CU”. These operations are categorized under Fabric, but charged separately. Fabric operations - Microsoft Fabric | Microsoft Learn

That wording directly confirms that Dataflow Gen2 refreshes are metered independently of your reserved F-SKU capacity even though they appear alongside Fabric in billing breakdowns.
