Premium Per User Copilot Feature

The cost of Fabric capacity depend on your usage on every workload in Fabric.

Fabric capacities (F-SKUs) are billed per capacity unit per hour, and the price depends on the SKU size you choose.

See the pricing reference :

Note : You can also pause/resume an F-SKU anytime in Azure, so you only pay for active hours.

2) yes, once you move to a Fabric capacity, you typically:

• Downgrade users from PPU to Pro licenses,

• And host your workspaces on the Fabric capacity.

Here’s why:

• Pro license users can view and publish reports hosted on a Fabric (F-SKU) capacity — no PPU required.

• XMLA endpoint connectivity is supported on Fabric capacities (F-SKU), so you’ll retain all your existing semantic model scenarios.

Replace PPU with Power BI Pro for all users.
