Optimize Microsoft Foundry, Microsoft Copilot Studio, Microsoft Fabric, and GitHub costs with Microsoft Agent prepurchase plan

Save on select services across Microsoft Foundry, Microsoft Copilot Studio*, Microsoft Fabric, and GitHub costs when you buy a prepurchase plan. Prepurchase plans are commit units (CUs) bought at discounted tiers in your purchasing currency for a specific product. The more you buy, the greater the discount. Purchased CUs pay down qualifying costs in US dollars (USD). So, for example if Microsoft Copilot Studio or Microsoft Foundry generates a retail cost of $100 based on Copilot Credit and Microsoft Foundry usage, then 100 Agent CUs (ACUs) are consumed.

Your Microsoft Agent prepurchase plan automatically uses your ACUs to pay for eligible Copilot and Microsoft Foundry usage during its one-year term or until Agent CUs run out. Your prepurchase plan Agent CUs start paying for your Copilot Credit and Microsoft Foundry usage without having to redeploy or reassign the plan. By default, plans are configured to renew at the end of the one-year term.

*Covers Copilot Credits-enabled agentic services: Microsoft Copilot Studio, Dynamics 365 first-party agents, and Copilot. Microsoft reserves the right to update Copilot Credit-eligible products.

Services covered by Microsoft Agent prepurchase plan

Prerequisites

To buy a prepurchase plan, you must have one of the following Azure subscriptions and roles:

• For an Azure subscription, the owner role or reservation purchaser role is required.
• For an Enterprise Agreement (EA) subscription, the Reserved Instances policy option must be enabled. To enable that policy option, you must be an EA administrator of the subscription.
• For a Cloud Solution Provider (CSP) subscription, follow one of these articles:
  • Buy Azure reservations on behalf of a customer
  • Allow the customer to buy their own reservations

Determine the right size to buy

To get started, estimate your expected Microsoft Foundry, Microsoft Copilot Studio, Microsoft Fabric, and GitHub usage for the term. This helps you determine the appropriate size for your prepurchase plan. Each prepurchase plan has a one-year term.

Example calculation:

Consider a hypothetical scenario where your organization plans to use:

• Copilot Credit: 1,500,000 credits for custom agents in Microsoft Copilot Studio
• Microsoft Foundry PTUs: 5,000 PTU hours for AI model deployments in Microsoft Foundry

Assumed pay-as-you-go rates (for illustration purposes):

• Copilot Credit at hypothetical $0.01 per credit = $15,000
• PTU usage at assumed $1.00 per PTU = $5,000
• Total estimated pay-as-you-go cost: $20,000

Assuming Tier 1 prepurchase plan (20,000 CUs):

• Estimated plan cost: $19,000
• Potential savings: $1,000 (approximately 5% discount)

This example demonstrates how the prepurchase plan can provide cost savings for organizations with predictable AI workload usage patterns.

Purchase Microsoft Agent Prepurchase Plan commit units

Purchase Microsoft Agent Prepurchase Plans in the Azure portal reservations.

1. Go to the Azure portal
2. Navigate to the Reservations service.
3. On the Purchase reservations page, select Microsoft Agent Prepurchase Plan.
4. On the Select the product you want to purchase page, select a subscription. Use the Subscription list to select the subscription used to pay for the purchase. The payment method of the subscription is charged the upfront cost for the reservation. Charges are not deducted from the enrollment's Azure Prepayment (previously called monetary commitment) balance or charged as overage.
5. Select a scope.
   • Single resource group scope - Applies the reservation discount to the matching resources in the selected resource group only.
   • Single subscription scope - Applies the reservation discount to the matching resources in the selected subscription.
   • Shared scope - Applies the reservation discount to matching resources in eligible subscriptions that are in the billing context. For Enterprise Agreement customers, the billing context is the enrollment.
   • Management group - Applies the reservation discount to the matching resource in the list of subscriptions that are a part of both the management group and billing scope.
6. Select how many Agent Credit commit units you want to purchase.
7. Choose to automatically renew the prepurchase reservation. The setting is configured to renew automatically by default. For more information, see Renew a reservation.

Change scope and ownership

You can make the following types of changes to a reservation after purchase:

• Update reservation scope
• Update who can view or manage the reservation. For more information, see Who can manage a reservation by default.

You can't split or merge a Microsoft Agent Prepurchase Plan. For more information about managing reservations, see Manage reservations after purchase.

How does benefit application work?

When you have multiple AI-related purchasing options, understanding how benefits are applied helps you maximize your cost savings. You might have several types of purchases for your AI workloads:

• Microsoft Foundry Provisioned Throughput reservation - Covers Microsoft Foundry PTU (Provisioned Throughput Units) usage
• Copilot Credit prepurchase plan - Covers Copilot Credit-specific usage
• Microsoft Agent prepurchase plan - Covers broader AI workloads including both Copilot Credit and Microsoft Foundry

Understanding benefit overlap

What is overlap? Overlap occurs when multiple benefits can cover the same usage. For example:

• Copilot credits are eligible for both Copilot Credit prepurchase plan and Microsoft Agent prepurchase plan
• Microsoft Foundry PTU workloads are eligible for both Microsoft Foundry PTU reservations and Microsoft Agent prepurchase plan

Benefit application order (precedence)

When overlap occurs, Microsoft applies benefits in this specific order to maximize your savings:

1. Microsoft Foundry PTU Reservations

   • Always applied first to PTU usage
   • PTU-specific and most cost-effective for provisioned throughput

2. Copilot Credit Prepurchase Plan

   • Applied next to Copilot-specific workloads
   • More granular benefit preserved for specialized use for Copilot Credit usage

3. Microsoft Agent Prepurchase Plan

   • Applied last to remaining AI usage across both platforms
   • Broader coverage for heterogeneous AI workloads for Copilot Credit and Microsoft Foundry usage

Important

Microsoft Agent prepurchase plan does not cover the purchase cost of other reservations or prepurchase plans - only actual usage costs.

Benefit application scenarios

These scenarios show how benefits work together in different purchasing combinations:

Scenario 1: Microsoft Foundry reservation only

What you have:

• Microsoft Foundry PTU reservation for 10 PTUs

How benefits apply:

1. Reservation covers first 10 PTUs at discounted rate
2. Additional PTU usage beyond 10 PTUs charged at pay-as-you-go rates
3. Non-PTU AI usage (like Copilot) charged at pay-as-you-go rates

Scenario 2: Copilot Credit + Microsoft Agent prepurchase plans

What you have:

• Copilot Credit prepurchase plan: 5,000 CCCUs
• Microsoft Agent prepurchase plan: 20,000 ACUs

How benefits apply:

1. Copilot workloads consume Copilot Credit prepurchase plan first (up to 5,000 CCCUs)
2. Additional Copilot usage draws from Microsoft Agent prepurchase plan
3. Microsoft Foundry usage draws from Microsoft Agent prepurchase plan

Scenario 3: Microsoft Foundry reservation + Microsoft Agent prepurchase plan

What you have:

• Microsoft Foundry PTU reservation: 15 PTUs
• Microsoft Agent prepurchase plan: 25,000 CUs

How benefits apply:

1. Microsoft Foundry PTU reservation covers first 15 PTUs
2. Overflow PTU usage draws from Agent prepurchase plan
3. All Copilot usage draws from remaining Agent prepurchase plan

Scenario 4: Complete coverage (all three benefits)

What you have:

• Microsoft Foundry PTU reservation: 10 PTUs
• Copilot Credit prepurchase plan: 3,000 CUs
• Microsoft Agent prepurchase plan: 15,000 CUs

How benefits apply:

1. Microsoft Foundry reservation covers PTU usage (up to 10 PTUs)
2. Copilot Credit prepurchase plan covers Copilot usage (up to 3,000 CUs)
3. Agent prepurchase plan covers overflow from both platforms

Note

Tiered pricing optimization: Microsoft Agent prepurchase plan automatically applies benefits at smallest tier pricing rates. For example, if you're using Custom Entity Lookup skills, benefits are calculated using the 0-1M text records pricing tier.

Cancellations and exchanges

Cancel and exchange operations aren't supported for Microsoft Agent prepurchase plans. All purchases are final.
