CI/CD Pipeline Cost Calculator

pipeline-cost-calculator

Read-onlyIdempotent

Use this when a user asks how much their GitHub Actions CI/CD pipeline costs per month. Takes average job duration in minutes, jobs per run, runs per month and the runner label (ubuntu-latest, windows-latest, macos-latest or self-hosted; matched case-insensitively). Uses GitHub list prices for standard hosted runners effective 1 Jan 2026 and GitHub Free's 2,000 included minutes for private repositories, drawn at list price. Self-hosted minutes carry no GitHub charge.
