GitHub Actions Minutes Calculator

Calculate GitHub Actions minute consumption and billing across runner types.

About GitHub Actions Minutes Calculator

Matrix jobs multiply consumption because each job bills separately, and runner type applies a further multiplier. A macOS matrix of three jobs bills thirty times an equivalent single Ubuntu job. macOS runners are where Actions bills unexpectedly escalate, and restricting them to release workflows rather than every push usually removes most of the cost.

Formula

GitHub Actions Minutes

Billable minutes = runs × duration × jobs × runner multiplier

multiplier: Windows bills at twice and macOS at ten times the Ubuntu rate
self-hosted: Consumes no billable minutes, only your own infrastructure

Worked example

With the default values below, GitHub Actions Minutes Calculator returns Billable Minutes of 21,600. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 5 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
