About this tool
Container Registry Cost Calculator
The Container Registry Cost Calculator computes monthly storage and egress costs from image size, version count, and pull frequency across Docker Hub, ECR, and DigitalOcean.
• Compare ECR vs DigitalOcean Container Registry costs for a given image fleet
• Calculate monthly registry cost before choosing a registry for a new project
• Model storage cost savings from reducing retained image versions from 50 to 10
• Determine whether Docker Hub Pro is cost-effective at current pull rates

FAQ
What does this tool tell you?
The Container Registry Cost Calculator computes monthly storage and egress costs from image size, version count, and pull frequency across Docker Hub, ECR, and DigitalOcean.
What affects the result most?
Docker Hub: free 1 private repo, Pro $5/mo unlimited — pull rate limits for free accounts. GitHub Container Registry: free for public images, included in GitHub packages for private. ECR: $0.10/GB/month storage + $0.09/GB data transfer out of AWS region.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
