AWS S3 Backup Calculator

Estimate S3 backup lifecycle costs for a cost-effective retention strategy.

Cost Effective Backup Strategy This calculator models lifecycle-based S3 backup retention. It is intentionally not based on S3 Standard pricing only. Retention Days must be at least 90 days to match the minimum retention period for this Glacier backup strategy. Monthly cost = (D / F) * (Standard days * Standard rate + Archive days * Archive rate)

Estimate S3 backup lifecycle costs before choosing a policy

The AWS S3 backup calculator estimates storage costs across backup size, retention, growth, and lifecycle transitions to Glacier classes. Use it to compare practical backup strategies instead of only looking at S3 Standard pricing.

It helps teams discuss cost tradeoffs for retention windows, archive timing, and restore expectations before implementing lifecycle rules.
