Re: Fabric Capacity - VNET Gateway Uptime

ShreyaSrinath · ‎06-09-2025

Hello,

I am trying to understand the VNET billing structure. Based on the documentation I saw, it looks like the VNET Data Gateway Charge is as follows for the time which the Gateway is on -

CU consumption rate: 2x
Price: 2x (CU Consumption rate) * 2 cores (per VNET Data Gateway) * $0.18 (Pay as You Go price for one CU per hour) = $0.72 per VNET / hour

My question is, what is the capacity usage - 2x what? Is it based on your FSKU? For example, if you have an F4 SKU would it be 4 CU *2? or is it a flat CU rate?

And is there any way I can see this broken out by item? Currently, the metrics app only displays the VNET Gateway Uptime as a single row.

Thank You!

Hi @ShreyaSrinath ,

Let me break down how VNET Gateway billing works in Microsoft Fabric as simply as possible.

The VNET Data Gateway is billed at a fixed rate: each active gateway member (node) is charged 4 Capacity Units (CUs) per hour, no matter which SKU you’re using. So, if you have three members running for an hour, that’s 12 CUs total. The price per CU depends on your region—for example, in US West it’s $0.18 per CU per hour, so three members for one hour would be $2.16.

You don’t need to worry about “2x” multipliers or your SKU’s core count; the billing is always 4 CUs per gateway node per hour. This is independent of your main Fabric SKU.

To check your usage, go to “Manage connections and gateways” in Fabric and count the number of active gateway members. Multiply that by 4 to get your hourly CU consumption.

Currently, the metrics app only shows the overall VNET Gateway Uptime as a single line. If you want a more detailed breakdown by item, you’ll need to map usage manually or use workspace filters as suggested in the community.

Billing itself appears under “Data Warehouse Capacity Usage CU meter” in your Azure bill and as “VNET Data Gateway Uptime” in Fabric’s Capacity Metrics.

If you have any more questions or need tips on managing costs, just let me know. This topic trips a lot of people up, so you’re definitely not alone.

Thanks @nilendraFabric for the explaination.

Where and how is this billed?

Hi @ShreyaSrinath,
Thank you for reaching out to the Microsoft fabric community forum.

VNET Data Gateway charges are tied to your Fabric capacity (e.g: F4) and appear in your Azure bill under “Data Warehouse Capacity Usage CU meter” and in the Fabric Capacity Metrics app as “VNET Data Gateway Uptime” . Each member consumes 4 CUs/hour ($0.72/hour at $0.18/CU-hour in US West), billed per minute.

Example: 3 members for 30 min = 6 CUs ($1.08). The “2x” formula is outdated; it’s a flat 4 CUs/hour per member.

To track usage, check member count in Manage connections and gateways in fabric and calculate members * 4 CUs/hour.

Thank you, @nilendraFabric for sharing valuable insights.
