About this calculator
Cloud storage prices vary 10-20× across providers. AWS S3 Standard is the convenient default at $0.023/GB. Cheaper options (B2, R2, Wasabi) save 5-15× on storage. Egress is the killer for active workloads — AWS charges $0.09/GB out (R2 and B2 have free or near-free egress). For static-asset CDN: R2 + Cloudflare beats S3 + CloudFront. For cold archive: Glacier Deep ($0.001/GB) is unbeatable.
Frequently asked
Why egress matters?+
For active sites/apps with lots of downloads: egress can dwarf storage cost. R2/B2/Wasabi free egress = huge for serving content.
AWS S3 vs. B2?+
S3: deep ecosystem, fastest, expensive egress. B2: cheap, slower, S3-compatible API. For backups: B2 wins. For prod web: S3 + CDN.
Glacier latency?+
Standard retrieval: 3-5 hours. Bulk: 5-12 hours. Expedited: 1-5 min. Pricing varies by tier.
When is Wasabi a trap?+
90-day minimum storage charge. Delete data within 90 days = pay for full 90. Plan accordingly.
CDN integration?+
CloudFront with S3: $0.085/GB egress + S3 cost. Cloudflare CDN with R2: free egress. Big difference.
