How to use the AWS S3 Cost Calculator

Compare AWS, Azure and Google Cloud storage costs for your real workload.

Cloud Storage Cost Intelligence compares what your data would cost on Amazon S3 and Azure Blob Storage (Google Cloud Storage classes are listed and show as unavailable until Google prices are loaded). You describe your data size, growth, reads, writes, retrieval, egress, retention and how often it is accessed, and it adds up storage, requests, retrieval, egress and early-deletion charges for each storage class. It recommends the cheapest class that fits, not just the lowest price per GB, shows what happens when your data grows 2x, 5x or 10x, suggests savings, and exports a PDF, Excel or CSV report. Prices come from the providers' official price lists and are estimates, not quotes.

Tips

The cheapest price per GB is often not the cheapest total. Retrieval, requests and egress can cost more than storage.
Use a sample CSV or JSON file to measure how well your files compress and how many rows repeat.
Archive classes need hours to restore. Turn off "I need to read it immediately" only if that is acceptable.
Short retention on cool or archive classes triggers early-deletion charges. The tool adds them for you.

Example

Input: 5 TB in S3 Standard, 1 TB read back a month

Output: Monthly cost per class and the cheapest class that fits

Frequently asked questions

What does an S3 bill include?

Storage per GB-month, PUT and GET requests, retrieval fees for the infrequent and Glacier classes, data transfer out to the internet, and early-deletion charges when objects are removed before the minimum duration (30, 90 or 180 days).

When is S3 Standard-IA cheaper than Standard?

When data is read rarely. Its storage is cheaper, but every GB read back costs a retrieval fee and objects are billed for at least 30 days and 128 KB. The calculator adds these for your numbers.

Are the prices current?

They come from the official AWS Price List; the date they were downloaded is shown in the tool.

Where do the prices come from?

From the official AWS Price List and the Azure Retail Prices API, downloaded into the app with the date shown on the page. Google Cloud prices need a free API key to be loaded; until then they are shown as unavailable. A price that cannot be matched is never guessed.

Is the result a quote?

No. It is an estimate from public pay-as-you-go list prices. Discounts, taxes, committed use and free tiers are not included.

Is my file uploaded?

No. A sample file is measured in your browser and never sent anywhere.
