What is the early deletion charge for Azure Cool and Archive tiers?

Cool tier has a minimum storage duration of 30 days, and Archive tier requires 180 days. If you delete or move a blob before the minimum duration, Azure charges the equivalent storage cost for the remaining days. The estimator flags this so you can factor early deletion risk into your cost model.

How does redundancy choice affect cost?

LRS (locally redundant) is the cheapest option, storing three copies in a single datacenter. GRS and GZRS replicate data to a secondary region for disaster recovery, roughly doubling storage costs. RA-GRS/RA-GZRS add read access to the secondary copy at a small premium. The estimator shows exact pricing for each option.

Does the tool account for Azure Blob operation costs?

Yes. Each read, write, and list operation has a per-10,000-operation charge that varies by tier. The estimator includes these operation costs alongside storage and retrieval fees for a complete monthly projection.

About This Tool

The Azure Storage Cost Estimator projects your monthly Azure Blob Storage bill across access tiers and redundancy configurations. It covers Hot, Cool, Cold, and Archive tiers with LRS, ZRS, GRS, RA-GRS, GZRS, and RA-GZRS redundancy options. Enter your storage volume, read/write operation counts, and data retrieval expectations to get a detailed cost breakdown including early deletion penalties for Cool and Archive tiers. This tool is essential for Azure architects planning data lake, backup, or media storage solutions who need to balance cost against access frequency and durability requirements.

When to Use This Tool

•Comparing monthly costs between Hot and Cool tiers for a web application's user-uploaded media library.
•Estimating the total cost of archiving compliance data in the Archive tier including retrieval fees for occasional audits.
•Evaluating the cost impact of upgrading from LRS to GRS redundancy for mission-critical backup data.
•Modeling Azure Blob Storage costs for a data lake that mixes frequently accessed analytics data with cold historical datasets.
