GitHub Actions Monthly Bill Estimator
Plug in your build volume and runner OS to see your monthly GitHub Actions bill and how much you would save on Latchkey.
GitHub Actions bills per minute, and the rate depends on the runner OS. This estimator turns your everyday numbers - builds per day, minutes per build, OS - into a monthly minute count, the GitHub-hosted overage cost after the 2,000 free minutes, and a side-by-side Latchkey figure.
GitHub-hosted list rates: Linux $0.008/min, Windows $0.016/min, macOS $0.08/min. Private repos include 2,000 free Linux-equivalent minutes/month. Monthly minutes = builds/day x minutes/build x 30. Latchkey small runners bill a flat ~$0.0025/min with 2,000 free minutes.
How the estimate works
- Monthly minutes = builds/day x minutes/build x 30.
- GitHub-hosted rate by OS: Linux $0.008/min, Windows $0.016/min, macOS $0.08/min.
- Private repos get 2,000 free Linux-equivalent minutes/month; only the overage is billed.
- Latchkey small runners bill a flat ~$0.0025/min, also with 2,000 free minutes.
Why the OS dropdown matters
Windows costs 2x Linux and macOS costs 10x Linux per minute. Switching the OS in the dropdown shows how much of your bill is driven by the runner choice rather than the workload itself.
