S3 Price Calculator
Estimate Your Amazon S3 Storage Costs
Amazon S3 (Simple Storage Service) is one of the most widely used cloud storage options, but with multiple storage classes, request types, and transfer fees, understanding your exact monthly cost can be tricky. This calculator helps you quickly estimate your S3 expenses based on your usage – whether you’re storing backups, hosting a static website, or managing a data lake.
What This Calculator Covers
This tool estimates your monthly S3 cost based on:
- Storage amount – how much data you’re storing, in GB
- PUT/COPY/POST requests – the number of write-type requests, in thousands
- GET/SELECT requests – the number of read-type requests, in thousands
- Data transfer out – how much data leaves AWS to the internet, in GB
How to Use This Calculator
Enter your expected monthly storage amount, request volumes, and data transfer out, then click Calculate to see your estimated total monthly cost.
Worked Example
Storing 1,000 GB (1 TB) in S3 Standard, with 50,000 PUT requests, 300,000 GET requests, and 200 GB of monthly data transfer out:
| Component | Cost |
|---|---|
| Storage (1,000 GB x $0.023) | $23.00 |
| PUT Requests (50,000 x $0.005/1,000) | $0.25 |
| GET Requests (300,000 x $0.0004/1,000) | $0.12 |
| Data Transfer Out (200 GB x $0.09) | $18.00 |
| Total Estimated Monthly Cost | $41.37 |
Understanding S3 Storage Classes
| Class | Cost per GB | Retrieval Time | Best For |
|---|---|---|---|
| S3 Standard | $0.023 | Instant | Frequently accessed data |
| S3 Standard-IA | $0.0125 | Instant | Infrequent access |
| S3 Glacier | $0.004 | Minutes | Archive data |
| S3 Glacier Deep Archive | $0.00099 | 12+ hours | Long-term archive |
Tips to Reduce S3 Costs
- Use Intelligent-Tiering to automatically move data to cheaper storage as access patterns change.
- Set lifecycle policies to archive or delete old data automatically.
- Compress large files before uploading.
- Avoid unnecessary data transfer between AWS regions.
- Use S3 Glacier Deep Archive for long-term storage you rarely need to retrieve.
