Capacity Reservation
Hi marius1106
Regarding your question, the solution provided by lbendlin addresses the issue. Once a reservation is made for the selected duration (one or three years), you will continue to pay the reserved price throughout the term, regardless of usage. However, if your usage exceeds the reserved capacity, any additional consumption will be charged at Pay-As-You-Go (PAYG) rates.
Additionally, while scaling up is possible by purchasing additional reserved capacity (which starts a new reservation contract), scaling down is not permitted mid-term. The original reservation commitment remains unchanged until its expiration.

Hello marius1106
Thank you lbendlin for sharing the helpful information.
Thank you for reaching out to Microsoft Fabric Capacity. We understand that you are seeking insights regarding capacity reservation. Let’s clarify this in detail:
Cancellation Policy: Microsoft Fabric reserved capacities follow Azure reservation policies. Pay-as-you-go subscriptions can be canceled anytime, while reserved instance (RI) purchases are subject to Microsoft's refund rules, typically allowing a prorated refund with a cancellation fee.
Exceeding Capacity Limits: Microsoft Fabric capacities are provisioned based on SKU limits (e.g., F2, F8, F16, etc.). If your workload exceeds the allocated capacity, the system will queue or throttle tasks instead of automatically incurring additional charges. There are no extra costs beyond your reserved capacity.

Hello v-karpurapud,
thank you for your answer. So is a reserved capacity different from the pay-as-you-go concerning the extra costs when exceeding capacity limits? Because I tested a lower capacity as pay-as-you-go and got extra costs as I exceeded the limit.
So did I understand that correct, that with the reserved Instance there are no extra costs any time?
Thanks,
Marius
Hello marius1106
Yes, you understood correctly! With Reserved Capacity, there are no additional costs beyond your purchased limit. However, workloads may be throttled or queued instead of scaling up automatically. In contrast, Pay-as-you-go scales dynamically, which can result in extra charges when capacity is exceeded.If you find this post helpful, please mark it as an "Accept as Solution" and give a KUDOS.

Hello @v-karpurapud,
now I understood my 2) better, thank you!
But for my first Question, I didnt understand the answer and Azure Doks. Which rules are defined for canceling a reserved capacity?
- For example after one year I dont want to extend the contract
- For example I want to cancel the contract 3 months before end
Thanks!
