Azure Container Registry cost: a flat daily fee by tier

Quick answer

Azure Container Registry bills a fixed daily fee by tier: Basic around $5/month, Standard around $20, Premium around $50. Each tier includes storage and throughput allowances; you pay overage beyond them and for geo-replication (per replicated region on Premium) and data transfer. The tier sets most of the bill, not per-pull usage.

Azure Container Registry stores and serves container images. Unlike ECR, which is pure usage-based, ACR uses a tiered daily fee that bundles storage and throughput, so most of your bill is simply which tier you picked.

The tier is the bill

Tier	Approximate monthly	Includes
Basic	~$5	Modest storage and throughput
Standard	~$20	More storage and throughput
Premium	~$50	Most storage/throughput, geo-replication, private link

Each tier includes a storage allowance and a throughput level; you pay overage only if you exceed the included storage. For most teams the daily fee is the whole cost, which makes ACR predictable.

What pushes you up a tier

Standard suits most teams. Premium is for higher throughput, larger storage, geo-replication across regions, private link, and content trust. Each geo-replicated region on Premium adds a fee, so replicate only the regions you deploy to, the same discipline as ECR replication.

Keeping ACR cost down

Pick the lowest tier whose included storage and throughput cover you, prune old images and untagged manifests so you do not pay storage overage or need a higher tier, and replicate only necessary regions on Premium. Because the fee is flat, the main levers are tier choice and not over-replicating.

FAQ

How is Azure Container Registry priced?

A fixed daily fee by tier: Basic around $5 per month, Standard around $20, Premium around $50. Each tier includes storage and throughput allowances, with overage charges beyond them plus geo-replication and data transfer costs.

Which ACR tier should I choose?

Standard suits most teams with its storage and throughput allowances. Use Basic for small or personal use, and Premium only when you need higher throughput, larger storage, geo-replication, private link, or content trust.

How much does ACR geo-replication cost?

On the Premium tier, each replicated region adds a fee on top of the base Premium cost. Replicate only the regions you actually deploy to, since mirroring every region multiplies the cost without benefit.

How do I reduce ACR cost?

Choose the lowest tier whose included storage and throughput cover you, prune old and untagged images so you avoid storage overage or a higher tier, and geo-replicate only necessary regions on Premium. The tier choice dominates the bill.

Is ACR cheaper than ECR?

They price differently: ACR uses a flat daily tier fee that bundles storage and throughput, while ECR is pure usage-based ($0.10 per GB-month plus transfer). ACR is more predictable; ECR can be cheaper for very small registries and pricier at scale. Compare against your storage and pull patterns.

Does C3X estimate ACR cost?

C3X prices the azurerm_container_registry resource and its SKU from your Terraform, so the tier's fixed fee appears before deploy. Storage overage and data transfer depend on usage, which you provide as assumptions.

What to do next

Price your registry tier before you deploy. C3X reads your Terraform and prices ACR and the rest of your stack against a live catalog. Start with the quickstart.
