AWS Storage Cost Calculator
Estimate monthly and projected storage costs for common Amazon S3 storage classes. Enter your usage below and click calculate.

How this AWS storage calculator helps
Cloud bills can feel unpredictable when storage, requests, retrieval, and data transfer are all charged separately. This AWS storage calculator gives you a practical estimate so you can budget before launching a workload. It is especially useful for teams handling backups, media archives, analytics logs, or application assets in Amazon S3.
Instead of looking at one line item, this calculator breaks your estimate into individual cost components and then projects spending over time with growth. That makes it easier to answer questions like: “What happens to my bill in 12 months if data grows 3% per month?”
What costs are included
- Storage: GB-month pricing for your selected S3 storage class.
- PUT/COPY/POST/LIST requests: request charges based on monthly call volume.
- GET/SELECT requests: retrieval-related request pricing.
- Retrieval GB: per-GB retrieval fees (important for infrequent access and archive tiers).
- Data transfer out: internet egress estimate with optional 100 GB free allowance.
Quick guide to storage classes
| Storage Class | Best For | Relative Cost | Retrieval Profile |
|---|---|---|---|
| S3 Standard | Frequently accessed application data | Higher storage, low retrieval friction | Immediate, no retrieval fee |
| S3 Standard-IA | Long-lived but less-accessed files | Lower storage than Standard | Retrieval fee applies |
| S3 One Zone-IA | Re-creatable infrequent data | Lower than Standard-IA | Retrieval fee applies |
| Glacier Instant Retrieval | Archive data needing quick access | Very low storage | Higher retrieval economics |
| Glacier Flexible Retrieval | Cold archive with flexible restore timing | Very low storage | Restore-based workflow |
| Glacier Deep Archive | Compliance and long-term retention | Lowest storage among listed tiers | Slow, retrieval-sensitive |
How to use the calculator effectively
1) Start with real usage signals
Pull 30-90 days of metrics from AWS Cost Explorer, S3 Storage Lens, and CloudWatch. Guessing request volumes can lead to large errors, especially in workloads with high object churn.
2) Model normal and peak months
Media platforms, e-commerce assets, and analytics jobs can spike traffic dramatically. Run at least two scenarios: baseline and peak. Keep both results in your planning doc.
3) Add growth assumptions
Most storage workloads grow. Even modest monthly growth compounds quickly, so your “month one” estimate is rarely your “month twelve” bill.
Common optimization ideas
- Use lifecycle policies to move cold objects to less expensive tiers.
- Reduce tiny-object sprawl by bundling logs where practical.
- Cache and CDN frequently downloaded content to reduce direct S3 egress.
- Delete incomplete multipart uploads and expired temporary data.
- Tag buckets and prefixes for better cost allocation and accountability.
Important caveats
This estimator is intentionally simplified for fast planning. Actual AWS pricing can vary by exact region, tiered usage levels, minimum storage durations, request type subtleties, and restore options. Use this page to plan architecture and budget ranges, then confirm final numbers with official AWS pricing calculators and your billing data.
Bottom line
A good AWS storage strategy is not only about finding the lowest per-GB number. It is about balancing access speed, durability requirements, operational simplicity, and total monthly cost. Use this calculator as a first-pass planning tool, then iterate with real usage and lifecycle automation.
