Summary
Estimate monthly cloud storage costs for AWS S3, Google Cloud Storage, and Azure Blob Storage based on storage size, request counts, and egress volume.
How it works
- Enter your total storage size in GB or TB.
- Set your estimated monthly PUT/POST/LIST and GET request counts.
- Enter your monthly egress (data transfer out) in GB.
- The calculator applies each provider's published per-GB, per-request, and per-GB egress rates.
- Results update instantly showing a side-by-side monthly cost estimate.
- Use the breakdown toggle to see storage, request, and egress line items separately.
Use cases
- Evaluate which provider is cheapest for a read-heavy workload like media serving.
- Estimate monthly spend before migrating an existing S3 bucket to GCS or Azure.
- Compare costs for a write-heavy pipeline that generates millions of PUT requests.
- Budget cloud storage line items for a new product or SaaS launch.
- Understand how egress costs affect total bill when serving files to end users.
- Identify the break-even point between providers at different storage scales.
