Tiered classes are shown as: first 50 TB / next 450 TB / over 500 TB. Region us-east-1 (N. Virginia); other regions price higher.
Storage prices for every class above were taken from the AWS S3 pricing page and cross-checked against three independent pricing references; only values all of them agree on are used here. Request pricing ($0.005 per 1,000 PUT/COPY/POST/LIST and $0.0004 per 1,000 GET) and the data-transfer-out tiers rest on two agreeing sources rather than the AWS page directly, so they are flagged as secondary, treat them as a good estimate, not a quote. Checked 2026-10-15.
One storage class is deliberately missing. S3 Express One Zone is priced at 0.11 per GB-month on the AWS regional page, 0.016 on one reference and 0.16 on another. Three sources, three different numbers, rather than publish a figure we cannot cross-check, it is left out of this calculator.
The 100 GB free tier is not applied by default. AWS lists 100 GB of free data transfer out per month, but that figure appeared in only one of the sources we checked, so the calculator starts it at zero and gives you the field to enter it. Put 100 in the allowance box to model it.
What this page leaves out: CloudFront egress, cross-region replication, KMS, Transfer Acceleration, Glacier retrieval fees and the minimum-duration charges that apply if you delete early. This is an estimate for planning, not a bill. For an authoritative figure use the AWS Pricing Calculator with your own account.

At us-east-1 S3 Standard rates, 500 GB is about $11.50 per month for storage alone. The tiered rates ($0.023 for the first 50 TB, $0.022 for the next 450 TB, $0.021 beyond 500 TB) only start to matter above about 51 TB, so a 500 GB bucket sits entirely in the first tier. Requests and data transfer out are charged on top.
Usually data transfer out. Storage is often the smaller line: 1 TB of S3 Standard is about $23 a month, but pushing that same 1 TB out to the internet costs about $90 at the standard egress rate. Serving public assets through CloudFront instead removes that charge entirely.
For storage, yes, $0.0125 per GB-month against $0.023, roughly half. But it adds a $0.01 per GB retrieval fee and a 30-day minimum storage duration, so data you read often, or delete early, can end up costing more than Standard. The comparison table above shows the storage difference; check your access pattern before switching.
A lot on storage: $0.00099 per GB-month is about 4% of Standard's rate, so 100 TB costs roughly $99 a month instead of about $2,250. The trade-off is a 180-day minimum storage duration, retrieval fees and retrieval measured in hours, which suits compliance archives rather than anything you might need quickly.
Not by default. AWS lists 100 GB per month of free data transfer out, but we could only confirm that from one source, so the calculator starts the allowance at zero, which over-estimates rather than under-estimates. Enter 100 in the allowance field to apply it.
