The AWS Calculator is a powerful online tool that helps you estimate and plan your Amazon Web Services (AWS) expenses. Whether you’re hosting a small website, running big data workloads, or managing enterprise-level cloud infrastructure, this calculator provides accurate cost projections across AWS services like EC2, S3, Lambda, RDS, and CloudFront.
It’s ideal for developers, startups, IT managers, and cloud architects looking to manage costs efficiently and prevent unexpected billing surprises.
💡 What Is the AWS Calculator?
The AWS Pricing Calculator is designed to estimate how much you’ll spend based on your chosen resources, configurations, and usage.
It simplifies the complex AWS pricing model by giving clear monthly and annual cost projections.
You can input details such as:
- Compute hours
- Storage space
- Data transfer
- Service usage frequency
…and instantly see your estimated AWS bill — before launching any instance or bucket.
⚙️ How to Use the AWS Calculator (Step-by-Step Guide)
- Select AWS Services
Choose the services you plan to use, such as EC2, S3, RDS, ECS, or Lambda. - Enter Usage Details
- Specify instance types (e.g., t3.micro, m5.large).
- Input number of hours per month.
- Define storage capacity in GB or TB.
- Include data transfer in/out.
- Add Region
AWS costs vary by region — select your preferred deployment region (e.g., US-East, Europe, Asia-Pacific). - Configure Additional Options
Include Elastic IPs, Load Balancers, Snapshots, or Reserved Instances for accurate estimates. - Review Cost Breakdown
The calculator displays:- Estimated monthly total
- Service-wise cost details
- Annual estimate with savings from reserved pricing
- Download or Share Results
Export or share your cost estimates with team members for budgeting and approval.
📊 Example Calculation
Let’s calculate the monthly cost for a simple AWS setup:
| Service | Configuration | Monthly Estimate |
|---|---|---|
| EC2 | t3.medium, 2 vCPU, 8GB RAM | $35 |
| S3 Storage | 200 GB | $5 |
| Data Transfer | 100 GB/month | $9 |
| CloudFront | CDN Usage | $7 |
✅ Estimated Monthly AWS Cost: $56/month
✅ Annual Estimate: $672/year
If you choose Reserved Instances, you can save up to 30%–70% on compute costs.
