Plan and troubleshoot Microsoft Fabric capacities with this self-contained, bright-mode estimator from GigXP.com. Add your interactive or background operations, choose an F-SKU (or map from P-SKU), and instantly see projected usage across the 10-minute, 60-minute, and 24-hour throttling windows. The tool models smoothing, bursting, and carryforward so you can spot when you’ll hit healthy, interactive delay, or rejection stages. Live charts, comparison tables, filters, and JSON import/export make it easy to test scenarios, share assumptions, and validate against the Fabric Capacity Metrics app before you scale.

Interactive Smoothing

Tip: CU-seconds = vCores × seconds (e.g., 4 vCores for 10 min ⇒ 4 × 600 = 2400 CU-seconds).

Throttling Stages

A quick glance at the throttling policy.

Healthy: No throttling.

Interactive Delay: 20s delay for new interactive ops.

Interactive Rejection: New interactive ops are rejected.

Full Rejection: All new requests are rejected.

SKU Capacity Comparison

Available CUs for each window.

SKU	CU/s	10-min	24-hour

Rules of Thumb

Interactive jobs smooth over 5–64 minutes.
Background jobs smooth over 24 hours.
Real-Time Intelligence skips the 20-second delay stage.
Pausing and resuming a capacity resets throttling.
