About

Cloud storage bills are rarely about the storage itself. They are dominated by Egress (data transfer out) and Operations (API requests). A single mismanagement of storage tiers - storing frequently accessed data in a Cold tier with high retrieval fees - can triple your monthly invoice. Precision is required.

This engineering-grade calculator models the Total Cost of Ownership (TCO) across 15+ providers and 50+ regions. Unlike basic tools, it accounts for the active lifecycle of your data using a weighted distribution between Hot, Warm, and Cold tiers. It exposes the hidden "taxes" of cloud infrastructure: retrieval fees per GB, Class A/B request costs, and minimum retention policies.

Formulas

The calculator uses a weighted cost model based on your Tier Distribution. The total monthly cost Ctotal is derived as:

Ctotal = n∑i=1 [
(Storage) V × wi × Pstorage,i+ (Ops) O × wi × Pops,i+ (Retrieval) R × wi × Pretr,i
 + (Egress) E × Pegress

Where wi represents the percentage of data in tier i (Hot, Warm, Cold), and P represents the specific price vector for that tier in the selected region.

Frequently Asked Questions

Tier-1 providers (AWS, Azure, GCP) charge a premium for their massive ecosystem integration, unparalleled durability SLAs (11 9s), and brand reputation. Challengers like Wasabi or Backblaze focus purely on storage, stripping away complex features to offer raw capacity at near-commodity prices, often removing Egress fees entirely to attract customers.
This refers to high Egress fees (Data Transfer Out). If a provider charges $0.09/GB to download your data, moving 1 Petabyte out of their cloud would cost ~$90,000. This financial barrier effectively "locks" you into their platform. Providers with free egress have low Lock-in Risk.
Most enterprises do not store 100% of their data in expensive Hot tiers. Usually, 20% is active (Hot) and 80% is archival (Cold/Glacier). This tool simulates that mix. If you select 80% Cold, the calculator applies cheaper storage rates for that portion but adds potential "Retrieval Fees" if you try to access it.
No. Cloud pricing is exclusive of local taxes (VAT, GST, Sales Tax), which vary by country. The prices shown are the base infrastructure rates published by the providers.
Yes. For backup scenarios (large files, few files), they are negligible. For "Data Lake" or "Web Serving" scenarios (millions of small files), Class A (PUT) and Class B (GET) request fees can sometimes exceed the cost of storage itself. Always optimize object size.
