Pricing Verified: September 2026. All displayed calculations are engineering planning estimates, not guaranteed vendor quotes.
Included Allowances & Minimums: AWS and Azure include 100 GB/month free internet egress. Backblaze includes 10 GB free storage and free egress up to 3× active stored volume. Wasabi enforces a 1 TB ($7.99/mo) minimum monthly storage charge and a 90-day minimum file retention policy; egress is free provided monthly downloads do not exceed total stored capacity (fair use policy).
Excluded Costs: Provider quotes exclude API transaction operations (PUT, GET, LIST requests), cross-region replication, accelerated transfer networks, and applicable local sales taxes.

What is the Cloud Storage Calculator?

Helps architects and businesses avoid cloud storage bill shock by modeling egress fees and API transaction costs.

How to Use This Tool

Enter your total stored data (GB or TB), your anticipated monthly download/egress traffic, and compare pricing across major providers.

Formula & Calculation Logic

The mathematical formula used to calculate this conversion is:

Total Cost = (Storage GB × Storage Rate) + (Egress GB × Egress Rate)

Step-by-Step Example Calculation

Here is a real-world calculation example demonstrating the mathematics:

Example: 10,000 GB storage + 2,000 GB monthly egress (US Standard Region, 2026 configured rates): AWS S3 Standard ($0.023/GB storage, 100 GB free egress, $0.09/GB egress): $230.00 + $171.00 = $401.00/mo Backblaze B2 ($0.00695/GB storage after 10 GB free; egress free up to 3× stored data): $69.43 + $0.00 = $69.43/mo Wasabi Hot Cloud Storage ($0.00799/GB storage with 1,000 GB minimum billable storage; free egress policy): $79.90 + $0.00 = $79.90/mo Google Cloud Standard ($0.020/GB storage + $0.12/GB egress): $200.00 + $240.00 = $440.00/mo Azure Blob Storage Hot ($0.0184/GB storage, 100 GB free egress, $0.087/GB egress): $184.00 + $165.30 = $349.30/mo Note: Rates reflect standard US tiers in CLOUD_PRICING_CONFIG. Excludes API operations (PUT/GET), multi-region replication, accelerated transfer tiers, minimum retention fees, and taxes.

Frequently Asked Questions

Egress is data transferred out of the cloud provider to the public internet. Egress fees are often 3x to 5x more expensive than storage fees on AWS and Azure.

Specialized storage clouds focus purely on object storage without enterprise compute ecosystems, offering flat $6-$7/TB rates with free or low egress.
