AZ-900 Azure Pricing Guide — Cost Management and Billing 2026
Master Azure pricing models, cost management tools, and savings strategies for the AZ-900 exam. Covers pay-as-you-go, reserved instances, TCO calculator, and...
Azure pricing and cost management topics make up 30–35% of the AZ-900 exam, making this one of the highest-weighted domains. Understanding how Azure charges for services — and how to control those costs — is essential for passing the exam and for real-world cloud adoption.
Pay-As-You-Go
The default Azure pricing model. You pay only for what you consume, billed by the second or hour depending on the resource. There are no upfront commitments and no cancellation fees. This model is ideal for unpredictable workloads and is the most flexible option — but it carries the highest per-unit price.
Reserved Instances (Reserved VM Instances)
Reserved Instances allow you to commit to using a specific VM size in a specific region for a 1-year or 3-year term in exchange for significant discounts — up to 72% compared to pay-as-you-go pricing. Reservations are available for VMs, SQL Database, Cosmos DB, and other services. They can be paid upfront (largest discount), monthly, or a mix of both. Reserved Instances are best for steady-state, predictable workloads.
Spot Pricing
Azure Spot VMs let you access unused Azure compute capacity at up to 90% discount versus pay-as-you-go. The trade-off: Azure can evict spot VMs with 30 seconds notice when capacity is needed elsewhere. Spot VMs are ideal for batch processing, rendering, stateless applications, and other interruptible workloads.
Dev/Test Pricing
Microsoft offers reduced rates for development and testing workloads through Azure Dev/Test subscriptions (linked to Visual Studio subscriptions). These discounts apply only to non-production environments and cannot be used for production SLAs. Dev/Test pricing covers VMs, SQL, App Service, and more at significantly reduced rates.
Azure Hybrid Benefit
Azure Hybrid Benefit lets customers bring their existing on-premises Windows Server or SQL Server licenses (with active Software Assurance) to Azure, saving up to 40% on Windows VMs and up to 55% on SQL Database. Combined with Reserved Instances, savings can reach 80%+.
AZ Breakdown
No commitment. Pay per second/hour. Highest flexibility, highest per-unit cost. Best for unpredictable or short-term workloads.
1 or 3-year commitment. Up to 72% savings vs pay-as-you-go. Best for predictable, steady-state production workloads.

Monitor and control EXISTING Azure spending. Set budgets, configure alerts, analyze cost trends, and optimize resources.
Understanding what drives Azure costs is key to both the AZ-900 exam and effective cloud financial management. Six major factors influence your Azure bill:
1. Resource Type
Different Azure resources have different pricing structures. Virtual machines are billed by compute hours and size. Storage accounts charge by GB stored and operations. Azure SQL Database charges per DTU or vCore. Always check the resource-specific pricing page.
2. Consumption (Usage)
Most Azure services follow a consumption model — the more you use, the more you pay. Some services (like Azure Functions) offer a free tier of executions per month before billing begins.
3. Region
Azure services are priced differently by region. Regions with higher operational costs (e.g., Brazil South, Japan) typically charge more than US or European regions. Choosing a less expensive region for non-latency-sensitive workloads can reduce costs significantly.
4. Bandwidth (Data Transfer)
Inbound data to Azure is generally free. Outbound data transfer (egress) is charged — the first 100 GB/month is often free, then tiered pricing applies. Data transfer between Azure regions (inter-region) also incurs charges.
5. Support Plan
Azure support plans range from Basic (free, included with all subscriptions) to Developer (9/mo), Standard (00/mo), Professional Direct (,000/mo), and Premier (custom). Higher tiers offer faster response times and dedicated support.
6. Subscription Type
Your Azure subscription type affects pricing. Free Trial subscriptions get 00 credit for 30 days. Pay-As-You-Go, Enterprise Agreements (EA), and Cloud Solution Provider (CSP) subscriptions each have different pricing structures and discount eligibility.
Cost Savings Strategies
The AZ-900 exam tests knowledge of how to reduce Azure costs. Key strategies include:
- Reserved Instances: Up to 72% savings for committed 1- or 3-year terms
- Azure Hybrid Benefit: Use existing Windows Server/SQL Server licenses — up to 40-55% savings
- Spot VMs: Up to 90% discount for interruptible workloads
- Auto-shutdown: Schedule VMs to shut down during off-hours for dev/test environments
- Right-sizing: Resize over-provisioned VMs to a smaller SKU
- Azure Advisor: Free built-in tool that gives personalized cost recommendations
- Choosing the right region: Select lower-cost regions for non-latency-sensitive workloads
For a deeper understanding of governance controls including Azure Policy, see our AZ-900 Governance Guide. These cost principles build on the foundational cloud concepts covered in the AZ-900 Cloud Concepts Guide.
AZ Checklist
Azure Cost Management + Billing is a built-in Azure service that gives you full visibility into your cloud spending. It is free for Azure customers and available directly in the Azure portal. Key capabilities include:
Cost Analysis
Visualize your spending over time with charts and breakdowns by resource group, service, tag, location, or subscription. You can filter by date range, compare months, and identify cost spikes quickly.
Budgets
Set monthly or quarterly spending budgets for subscriptions or resource groups. Budgets track your actual or forecasted spending against a defined threshold and can trigger alerts automatically.
Cost Alerts
Three types of alerts are available: budget alerts (spending reaches threshold), credit alerts (Azure monetary credit balance is consumed), and department spending quota alerts (for Enterprise Agreement customers). Alerts are sent via email to designated recipients.
Recommendations via Azure Advisor
Azure Advisor integrates with Cost Management to surface cost optimization recommendations — such as resizing underutilized VMs, deleting idle resources, buying reservations for consistently running VMs, and more. Azure Advisor is free and checks five categories: Cost, Security, Reliability, Operational Excellence, and Performance.

AZ Pros and Cons
- +Understanding the full cost structure — exam fees, study materials, retakes, renewal — enables accurate financial planning
- +Many states, employers, and professional associations offer partial or full reimbursement for certification costs
- +Free and library-accessible study resources can significantly reduce preparation costs without sacrificing quality
- +Early investment in quality preparation materials typically reduces the total cost by avoiding costly retakes
- +Certification ROI in salary increases often recoups the total investment within 1–2 years in most markets
- −Total costs including study materials, exam fees, and time investment are typically 2–3x the exam fee alone
- −Fee assistance availability varies widely by employer, state, and professional organization — not universally accessible
- −Cost increases over time as credentialing bodies raise fees — delaying creates additional financial pressure
- −Retake fees (often 50–100% of original exam fee) make first-attempt failure significantly more expensive than budgeted
- −Hidden costs such as study group memberships, supplementary resources, and exam prep services add up quickly
