Frequently Asked Questions
How accurate is this ECR pricing calculator?
This ECR pricing calculator uses official AWS pricing data from Amazon's public pricing API. It accounts for storage tiers and data transfer costs for private and public repositories. Pricing is consistent across all AWS regions for ECR. For production budgets, verify costs in the AWS Billing console.
Should I use private or public ECR repositories?
Use private repositories for proprietary container images that should only be accessible within your organization. Use public repositories (ECR Public Gallery) for open-source projects or images you want to share publicly. This calculator bills all entered storage for either repository type.
When is ECR data transfer free?
Data transfer from ECR to AWS services (EC2, ECS, Lambda, Fargate, App Runner) in the same region is always free. For public repositories, transfer to any AWS region is free. Cross-region or internet transfer from private repositories follows standard AWS data transfer rates (tiered pricing starting at $0.09/GB).
What is ECR Archive and when should I use it?
ECR Archive is a cost-optimized storage class for inactive container images you need to retain but don't actively pull. It has a minimum 90-day retention period. Images in archive cannot be pulled directly - they must be retrieved first ($0.03/GB). Use archive for compliance, disaster recovery, or old version retention.
How does public repository data transfer work?
Public repository data transfer is billed to the downloader rather than the repository owner. This calculator excludes downloader charges and models the repository owner's storage costs.
What is ECR managed signing?
ECR managed signing automatically signs container images as they're pushed, using the identity of the entity pushing the image. This helps verify that images are from trusted sources. Pricing is $0.02 per signature. You're only charged for successfully generated signatures.
