Amazon S3 Cost Calculator
Enter GB stored, GB egress to the internet, writes (PUT/COPY/POST/LIST) and reads (GET) per month. Defaults to US East (N. Virginia) S3 Standard list prices. See storage, request and egress lines plus total. Upload IN and same-Region / CloudFront transfers are free (CloudFront bandwidth is not modeled). Estimates only; AWS pricing page prevails.

Breakdown

Default region: US East (N. Virginia) / S3 Standard. Storage $0.023 / GB-month first 50 TB, $0.022 next 450 TB, $0.021 above 500 TB. Requests: PUT/COPY/POST/LIST $0.005 per 1,000; GET $0.0004 per 1,000. Data transfer OUT to internet (account-wide): first 100 GB/month free, next 10 TB $0.09/GB, next 40 TB $0.085/GB, next 100 TB $0.07/GB, over 150 TB $0.05/GB. Upload IN, same-Region to other AWS services, and to CloudFront are free. Serving via CloudFront moves bandwidth to CloudFront pricing (not modeled — do not invent CloudFront rates). Glacier / S3 IA depth skipped this MVP. Example: 500 GB, 2 TB egress, 1M writes, 40M reads → storage $11.50 + egress $175.32 + writes $5.00 + reads $16.00 ≈ $207.82.

How it works
- How much does Amazon S3 Standard cost in us-east-1?
- Storage: $0.023/GB-mo first 50 TB, $0.022 next 450 TB, $0.021 above 500 TB. PUT/COPY/POST/LIST $0.005 per 1,000; GET $0.0004 per 1,000. Internet egress: first 100 GB/month free (account-wide), then $0.09 / $0.085 / $0.07 / $0.05 per GB by tier (as of 2026-11-02).
- Why is egress so expensive on S3?
- Public internet egress is billed after a 100 GB free allowance. At 2 TB egress on 500 GB stored, egress alone is (2048−100)×$0.09 = $175.32 — often dwarfing storage ($11.50) and requests.
- Are uploads and CloudFront free?
- Data transfer IN to S3 and same-Region transfers to other AWS services are free. Serving via CloudFront moves bandwidth to CloudFront pricing (not modeled here — do not invent CloudFront rates).
- Does this cover Glacier or S3 IA?
- This MVP is S3 Standard in US East (N. Virginia) only. Glacier / IA / Intelligent-Tiering are advanced footnotes — use the AWS calculator for those classes.
- Example: 500 GB, 2 TB egress, 1M writes, 40M reads?
- Storage 500×$0.023 = $11.50; egress (2048−100)×$0.09 = $175.32; writes 1M×$0.005/1k = $5.00; reads 40M×$0.0004/1k = $16.00 → about $207.82 / month.
