Compare monthly cost across every S3 storage class using live AWS pricing, and find the retrieval frequency where each one wins.
For this data size and object count, the storage class that costs the least in each range of monthly retrievals.
ℹ️ How this is calculated
• Prices come from the public
AWS Price List Bulk API. Your browser fetches them directly from AWS. The region list is cached for 90 days and each region's prices for 30 days.
• A "retrieval" reads the whole data set once: one GET per object, plus any per-GB retrieval fee. Glacier Flexible Retrieval and Deep Archive also pay a restore request and fee, and the restored copy is billed at Standard rates for 1 day.
• Minimum billable sizes are included: 128 KB per object for IA and Glacier Instant Retrieval, and 40 KB of overhead per object for Glacier Flexible Retrieval and Deep Archive.
• Intelligent-Tiering is shown at its steady state. Objects accessed at least monthly stay in Frequent Access, objects untouched for 30 days move to Infrequent Access, and after 90 days to Archive Instant Access. The optional archive tiers are not modeled.
• Not included: data transfer out to the internet (the same for every class, so it doesn't move the break-even points), upload/PUT and lifecycle transition fees, the free tier, and early-deletion charges (minimum storage duration: 30 days for IA, 90 for Glacier IR and Flexible Retrieval, 180 for Deep Archive).
