AWS Pricing Calculator
Estimate your AWS cloud computing costs with this interactive calculator. Includes EC2, S3, Lambda, and data transfer costs.
How AWS Pricing Works
AWS calculates costs based on resource usage across different services:
- Formula: Total Cost = (Compute + Storage + Data Transfer) × Usage Hours
- Compute Cost: EC2 instances, Lambda functions, ECS containers
- Storage Cost: S3 storage, EBS volumes, DynamoDB
- Data Transfer Cost: Inbound/outbound data movement

Analysis & Recommendations
Your estimated monthly cost of $1,407.60 falls within normal range for similar usage.
- Consider Reserved Instances for consistent workloads to save up to 75%
- Use S3 Intelligent-Tiering for unpredictable access patterns
- Implement automated shutdown policies for non-production environments
- Monitor and optimize data transfer costs by using CloudFront
Understanding AWS Pricing
EC2 (Elastic Compute Cloud): Virtual servers in the cloud. Pricing varies by instance type, region, and billing option (On-Demand, Reserved, Spot).
S3 (Simple Storage Service): Object storage service. Costs depend on storage class, amount stored, and data transfer.
Lambda: Serverless computing. Pay only for the compute time consumed, measured in increments of 100ms.
Pay-as-you-go: No upfront payments, pay only for what you use. Ideal for variable workloads.
Reserved Instances: Commit to capacity for 1 or 3 years to get significant discounts.
Savings Plans: Commit to a specific amount of usage over 1 or 3 years for flexible discount options.
Regional Pricing: Costs vary significantly between AWS regions. US East (N. Virginia) is generally the cheapest.
Egress Charges: Data transfer out of AWS is charged separately and can accumulate quickly.
Free Tier: AWS offers a limited free tier for first-year accounts and certain services.
AWS Pricing Quiz
If your compute cost is $0.10/hour, storage cost is $0.02/month, and data transfer cost is $0.09/GB, with 720 usage hours and 100GB data transfer, what is the total monthly cost?
Step 1: Compute Cost = $0.10/hour × 720 hours = $72.00
Step 2: Storage Cost = $0.02/month (given) = $0.02
Step 3: Data Transfer Cost = $0.09/GB × 100GB = $9.00
Step 4: Total Cost = $72.00 + $0.02 + $9.00 = $81.02
This question tests understanding of the basic AWS cost formula: Total Cost = (Compute Cost + Storage Cost + Data Transfer Cost) × Usage Hours. It requires applying the formula with given values.
Compute Cost refers to the expense of running virtual machines or processing power in the cloud, typically measured per hour or second.
Always convert units to match the same time period (monthly in this case). Compute costs are typically hourly, while storage costs are usually monthly.
Which AWS pricing model offers the highest potential savings for consistent workloads?
Reserved Instances offer up to 75% savings compared to On-Demand pricing when committing to 1 or 3 years of usage. They're ideal for predictable workloads.
Combine Reserved Instances with Savings Plans for maximum savings on mixed workloads. Use Convertible Reserved Instances for more flexibility.
A company uses a t3.medium EC2 instance 24/7 for $0.0416/hour. What would be their approximate monthly cost? How much could they save by switching to Reserved Instances?
Monthly On-Demand Cost: $0.0416/hour × 24 hours/day × 30 days = $29.95
Potential Savings: With Reserved Instances (1-year term, no upfront), savings could be around 30-40%, saving approximately $9-12/month.
Don't forget to account for actual usage hours vs. 24/7. Many applications don't need to run constantly. Also, remember that Reserved Instance savings depend on commitment length and payment option.
A web application serves 10TB of data monthly to users in Asia-Pacific. If the egress cost is $0.09/GB, what is the monthly data transfer cost?
10TB = 10,000GB
$0.09/GB × 10,000GB = $900/month
This highlights how data transfer can become a significant portion of cloud costs, especially for content-heavy applications.
Use Amazon CloudFront (CDN) to cache content closer to users, reducing direct egress from origin servers. Consider compression to reduce data volume.
A company stores 500TB of data with varying access patterns. 400TB is infrequently accessed, and 100TB is frequently accessed. Compare costs between S3 Standard and S3 Intelligent-Tiering for this scenario.
S3 Standard: $0.023/GB/month × 500TB = $11,500/month
S3 Intelligent-Tiering: $0.0125/GB/month × 100TB (frequent) + $0.01/GB/month × 400TB (infrequent) = $1,250 + $4,000 = $5,250/month
Savings: Approximately $6,250/month with S3 Intelligent-Tiering
Match storage class to access patterns: S3 Standard for frequent access, S3 IA for infrequent access, S3 Glacier for archival. Always consider access frequency and retrieval needs.
Community Q&A
Q: How do I optimize AWS costs for a startup with unpredictable usage patterns?
A: For startups with unpredictable usage, consider this approach:
Compute:
- Start with On-Demand instances for development and testing
- Use Spot Instances for fault-tolerant workloads (batch processing, analytics)
- Consider Fargate for containerized applications to avoid server management
Storage:
- S3 Intelligent-Tiering for data with unknown access patterns
- S3 Lifecycle policies to automatically move data to cheaper storage classes
Monitoring:
- Set up AWS Budgets with alarms at 80% of projected spend
- Use Cost Explorer to identify spending trends
- Implement resource tagging from day one for cost allocation
As your usage stabilizes, transition to Reserved Instances for predictable workloads to maximize savings.
Q: What are the hidden costs I should watch out for when using AWS?
A: Beyond the obvious compute and storage costs, watch for these often-overlooked expenses:
Data Transfer Costs:
- Egress charges for data leaving AWS (can be substantial for content-heavy apps)
- Cross-region replication charges
- Data transfer between AWS services in different regions
Management & Support:
- AWS Support plans (beyond Basic)
- Managed services like RDS, ElastiCache (include underlying EC2 costs)
- API calls to various AWS services
Additional Charges:
- NAT Gateway fees for private subnet internet access
- ELB (Elastic Load Balancer) charges per hour and per GB
- IAM authentication requests
- DNS queries to Route 53
Use AWS Pricing Calculator and Cost Explorer regularly to catch unexpected charges early.
