How to use the S3 Glacier 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: 50 TB of backups, restored twice a year

Output: Cheapest archive class including retrieval and early deletion

Frequently asked questions

Is Glacier Deep Archive always the cheapest?

For storage, usually yes, but restores take hours and cost per GB, and objects are billed for at least 180 days. If you read the data often or delete it early, another class can be cheaper overall.

What if I need the data immediately?

Tick "I need to read it immediately" and classes that need hours to restore are left out of the recommendation.

Does it include Azure Archive?

Yes, Azure Blob Archive is compared too, with its 180-day minimum.

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.
