Fabric Platform Sizing for the initial sizing
Hi All,
I am looking for the way to estimate the CU for fabric for a given work load. Is there any way we can estimate the number of CU's consumed ?
I know how many feeds are going to be ingested with what data volume and their data volumn.
TIA
Rahul
Hi rahuldwh,
Thank you for reaching out to the Microsoft Fabric community forum.Microsoft Fabric does not currently provide a direct CU estimation tool, but you can estimate CU consumption based on workload characteristics.
To monitor and optimize CU consumption, you can use the Fabric Capacity Metrics App, which provides insights into how different workloads (data ingestion, transformations, queries, etc.) are utilizing your capacity. This will help you adjust your capacity as needed.

According to the Microsoft documentation, a F2 gives you 2 CU/second, a F4 gives 4 CU/second, a F8 gives you 8CU/second and so on and so forth.
From the Fabric Capacity Metric report, we can see the detailed CU consumption per item. For an example, assume we have a test run for 14 days on production-scale workloads on our dev-capacity resulting in approximately 5,400,000 CUs consumed.
Using the information above, we know that the SKU-equivalent can be calculated as
"CU Usage"/("Number of days" * 24 hours/day * 3600 seconds/hour)
Example:
6,000,000/(14*24*3600) = 4.46 - v-ssriganesh

Hi Sri,
My customer is looking for TCO for fabric services for his exising workload in Azure cloud. So was looking for some estimation method or approximation.
