How to use the Cloud Storage Cost Calculator: AWS vs Azure vs Google 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, Azure Blob Storage and Google Cloud Storage. 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.
Choose providers and a region Describe your data and how it is used Review the recommendation and download the report 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: 10 TB, 500 GB growth a month, occasional access, 200 GB retrieval
Output: Best fit, cost per month and per year, 2x / 5x / 10x growth

Frequently asked questions Which cloud is cheapest for storage? It depends on how you use the data. The lowest price per GB is often not the cheapest once requests, retrieval, egress and minimum-duration charges are added, so this tool compares your whole workload.
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.
