Are you overpaying for F64?

F64 is where a lot of teams land after a P1 migration or a trial, often without checking whether the workload needs it. Four things decide whether it's the right size:

• Utilization. If peak CU in the Capacity Metrics app rarely goes above 40–50%, a smaller SKU may carry the load.
• Hours actually used. An F SKU on pay-as-you-go can be paused; a capacity idle at night and on weekends is paid for anyway if it never pauses.
• Pay-as-you-go vs reserved. A 1-year reservation is roughly 41% cheaper per hour, but only pays off if the capacity runs most of the month.
• Viewers vs Pro licenses. F64 is the threshold where read-only viewers no longer need Power BI Pro. Going below F64 can move cost from capacity to licenses.

This is an estimate, not a quote. Uses Microsoft public list prices in USD (F SKUs: $0.18 per CU-hour pay-as-you-go; 1-year reservation ≈ 41% lower; P SKUs at published monthly price), 730 hours/month. Power BI Pro at $14 per user/month list price. On F64 and above, viewers can read content in that capacity with a free Fabric license; below F64 every viewer needs Pro. Your price depends on your agreement and currency. Source: Microsoft Fabric pricing, Fabric licenses (Microsoft Learn).
