Cloud Computing Cost Comparison 2026: AWS vs Azure vs GCP

Cloud computing is now the #2 expense at midsize IT companies, behind only labor. The average company spends $1.2 million annually on cloud services, and 30% of that is estimated to be wasted on unused or over-provisioned resources.

This guide compares pricing across the three major cloud providers to help you make informed decisions and optimize spending.

Quick Answer: For most workloads, the three providers are within 10-15% of each other in pricing. The real cost differences come from commitment discounts, data egress fees, and service-specific pricing.

General Purpose Instances (4 vCPU, 16GB RAM, Linux, US East):

Provider	Service	On-Demand/hr	1-Year Reserved	3-Year Reserved
AWS	m7i.xlarge	$0.192	$0.121 (37% off)	$0.076 (60% off)
Azure	D4s v6	$0.192	$0.115 (40% off)	$0.073 (62% off)
GCP	n2-standard-4	$0.194	$0.122 (37% off)	$0.087 (55% off)

GPU Instances (NVIDIA A100):

Provider	On-Demand/hr	Spot/Preemptible
AWS (p4d)	$32.77	$9.83-$15
Azure (NC A100)	$32.77	$10-$16
GCP (a2-highgpu)	$31.21	$9.36-$12

Key Takeaway: On-demand prices are nearly identical. The real savings come from commitment plans (reserved instances or savings plans) and spot/preemptible instances.

Object Storage (per GB/month):

Tier	AWS S3	Azure Blob	GCP Cloud Storage
Standard	$0.023	$0.018	$0.020
Infrequent Access	$0.0125	$0.010	$0.010
Archive	$0.004	$0.002	$0.004

Block Storage (SSD, per GB/month):

Provider	Standard SSD	Premium SSD
AWS EBS gp3	$0.08	$0.125
Azure Premium	$0.10	$0.15
GCP PD-SSD	$0.17	$0.17

Azure tends to be cheapest for cold/archive storage. AWS is competitive for standard storage. GCP block storage is more expensive but simpler pricing.

1. Data Egress (the "cloud tax") All three providers charge for outbound data transfer:

• First 100 GB/month: Free (all providers)
• 100 GB - 10 TB: $0.08-$0.09/GB
• At scale: A company transferring 10 TB/month pays $800-$900/month just in egress

2. Support Plans

• Basic: Free (limited)
• Developer: $29-$100/month
• Business: $100+/month or 5-10% of spend
• Enterprise: $5,500+/month or 3-10% of spend

3. Monitoring & Logging

• CloudWatch/Monitor/Cloud Monitoring: $0.30-$3.00 per metric per month
• Log ingestion: $0.50-$0.75 per GB
• Can easily reach $500-$5,000/month for large deployments

4. API Gateway & Load Balancer

• Load balancers: $15-$25/month each + data processing fees
• API Gateway: $1-$3.50 per million requests

5. Managed Databases

• 30-80% premium over self-managed
• Multi-AZ deployments double the cost

1. Right-sizing - 40% of cloud instances are over-provisioned. Use provider tools (AWS Compute Optimizer, Azure Advisor, GCP Recommender) to identify waste. 2. Reserved/Committed Use - Save 30-60% with 1-3 year commitments for predictable workloads. 3. Spot/Preemptible Instances - Save 60-90% for fault-tolerant batch processing, CI/CD, and dev/test environments. 4. Auto-scaling - Only pay for what you use by implementing proper auto-scaling policies. 5. Storage Lifecycle Policies - Automatically move old data to cheaper storage tiers. 6. Shut Down Dev/Test - Schedule non-production environments to run only during business hours (save 65%). 7. Multi-Cloud Strategy - Use each provider's strengths. GCP for data/ML, AWS for breadth, Azure for Microsoft integration. But beware of added complexity.

Companies that actively optimize typically reduce cloud spend by 25-35%.

Quick answer: Compare cloud computing costs across AWS, Azure, and Google Cloud in 2026. Pricing by service type, hidden costs, and optimization tips. Treat this page as a planning guide first: identify the cost drivers, document the assumptions, run the most relevant calculator when one is available, then confirm any current price, rate, fee, legal threshold, or vendor plan with a primary source before making a decision.

The safest way to use a cost guide is to separate stable decision logic from values that can change. Stable decision logic includes what to compare, which questions to ask, and which tradeoffs matter. Changeable values include market prices, local permit fees, tax thresholds, insurance terms, labor rates, vendor plan limits, legal deadlines, and government program rules.

Use the guide in four steps:

• Define the exact situation you are pricing or comparing.
• List the assumptions that can change by location, provider, date, or jurisdiction.
• Run a calculator with your own numbers instead of relying on a generic range.
• Save the assumptions and source dates so you can update the estimate later.

This keeps the guidance useful even when market prices, tax rules, vendor plans, or local requirements change. If two assumptions drive most of the result, create a low, middle, and high scenario instead of relying on a single estimate. If the article affects a contract, claim, loan, tax filing, or regulated purchase, use the estimate as a screening tool and verify the final decision with the official source or a qualified professional.

The most useful next step is to turn the article into a scenario you can test. Use the related calculator cards on this page to test the scenario with your own assumptions before treating any range as a budget.

Example workflow: start with a conservative input, record the result, change one assumption at a time, then compare the range of outcomes. If the result depends on a current rate, filing fee, vendor plan, local permit, or government threshold, verify that input before relying on the estimate.

Use the result to ask better follow-up questions: what is included, what is excluded, what changes by location, what expires, and what proof is needed. For quotes or vendor comparisons, ask for the same line items from each provider so the totals are comparable. For finance or legal decisions, record the date of each source because rates, limits, and rules can change within the same year.

For business and AI topics, verify vendor pricing, seat limits, standards, labor assumptions, and compliance requirements against official vendor documentation or standards-body pages before budgeting.

Before using this guide for a quote, budget, claim, or purchase decision, check:

• The source name and publication or effective date
• Whether the number applies nationally, locally, or only to a specific provider
• Whether taxes, fees, labor, materials, subscriptions, or eligibility rules are excluded
• Whether a professional quote, official form, or regulator page is needed for your case

If a source-sensitive number is not shown with a source date, treat it as a placeholder for planning. Replace it with the official value before publishing a quote, filing paperwork, choosing a provider, or making a purchase decision. This is especially important for legal deadlines, government fees, tax credits, mortgage rates, insurance premiums, and vendor pricing plans.
