The Real Price of Cloud Storage: Why the Number on the Pricing Page Is Almost Never Your Number

Four cost components. Most teams only check one. Here’s what the other three are costing you.

The Advertised Price Is a Floor

Every cloud storage provider lists a storage price. AWS S3: $0.023/GB/month. Backblaze B2: $0.006/GB/month. These numbers are real — and they are almost never what you actually pay.

The difference between the advertised price and your real bill is determined by three additional cost components that most procurement conversations and engineering evaluations never surface:

• Egress fees — charged per GB of outbound data transfer

• API call costs — charged per request (PUT, GET, COPY, LIST)

• Per-user licensing — relevant for Dropbox Business, Box, and similar providers

The combination can easily double or triple the headline price for an active SaaS workload.

A Component-by-Component Breakdown

1. Egress Fees

Egress fees are charged every time data leaves a cloud network. AWS charges $0.09/GB for data transferred to the internet. GCP charges $0.08–$0.12/GB depending on region and destination. Azure charges $0.087/GB.

For a SaaS company retrieving 20% of its stored data monthly, egress fees can exceed the storage cost itself. They are invisible until they appear on a bill — and they are designed to compound with usage.

2. API Call Costs

S3 charges $0.005 per 1,000 PUT, COPY, POST, or LIST requests and $0.0004 per 1,000 GET requests. For applications making millions of API calls per month — which is normal for any active product — this adds tens to hundreds of dollars per month.

3. Per-User Licensing

Dropbox Business charges per seat regardless of storage usage. For a 20-person team, the per-user cost can exceed the storage cost on S3, and it grows with headcount rather than data volume.

Real total cost = storage + egress + API calls + per-user licensing.

Comparing providers on storage price alone is comparing one-quarter of the real number.

What the Cost Comparison Calculator Does

The StorX Cloud Storage Cost Comparison Calculator asks three questions: your storage volume, your monthly retrieval percentage, and your team size. It then returns a side-by-side total cost comparison across AWS S3, GCP, Azure, Backblaze B2, Dropbox Business, and StorX.

All four cost components are calculated and displayed separately, so you can see exactly where the difference between providers comes from — not just the bottom line.

The tool is honest about cases where AWS wins: for workloads with minimal retrieval, or where compliance requirements create a genuine constraint, the calculator says so directly.

A Real Comparison: 10TB SaaS Workload

A SaaS company with 10TB stored and 20% monthly retrieval (2TB/month):

• AWS S3: ~$230 storage + $184 egress + $50 API = ~$464/month

• Backblaze B2: ~$61 storage + $0 egress = ~$70/month

• StorX: Flat subscription, $0 egress, $0 API — listed price is real price

The AWS vs. StorX comparison in this scenario is not close. But the comparison only becomes visible when all four components are in the same calculation.

Why Pricing Transparency Is a Values Statement

StorX was built on flat, predictable pricing specifically because unpredictable cloud bills are not just a financial problem — they are a trust problem. When your cost model penalises you for using your own data, your provider has structurally misaligned its incentives with yours.

Flat pricing means the price on the page is the price you pay. Egress is free. API calls are included. The cost of storing and using data scales linearly with data volume — not with how actively your users and applications access it.
