Does Cloud Build have a free tier?

Yes. Cloud Build provides 120 free build-minutes per day for the e2-medium machine type. Builds using higher-spec machine types are charged from the first minute. The free tier resets daily, not monthly.

What factors most affect Cloud Build costs?

The primary cost drivers are machine type (higher CPU/memory costs more per minute), build duration, and build frequency. Optimizing Docker layer caching, using smaller base images, and parallelizing build steps can significantly reduce both duration and cost.

About This Tool

The Cloud Build Cost Estimator helps you project monthly costs for Google Cloud Build based on your build configurations. You can specify machine types, build frequency, average build duration, and concurrent builds to get a detailed cost estimate. The tool shows how different machine types (e2-medium, e2-highcpu, custom) and build volumes affect your spending, and accounts for the free tier included with Cloud Build.

When to Use This Tool

•Estimate Cloud Build costs when setting up CI/CD pipelines for a new GCP project.
•Compare the cost of different Cloud Build machine types to find the optimal balance between build speed and cost.
•Project monthly costs for scaling your build pipeline as your team grows and build frequency increases.
•Evaluate whether Cloud Build is cost-competitive with other CI/CD services for your specific usage patterns.
