Commit Frequency Calculator

Calculate average commit frequency per contributor or repository over time.

About Commit Frequency Calculator

Commit frequency is a coarse but useful activity signal. Formula: commits_per_day = total_commits / days. Splitting the window in half and comparing rates reveals whether activity is accelerating, slowing, or steady — useful for spotting a stalling project or a crunch period before a release.

Formulas

Commits per day

commits_per_day = total_commits / days

total_commits
Total commits in the analyzed period
days
Number of days in the period

Trend percentage

trend_percent = (recent_rate - early_rate) / early_rate × 100

recent_rate
Commits per day in the recent half
early_rate
Commits per day in the earlier half

Worked example

With the default values below, Commit Frequency Calculator returns Average Commits per Day of 8.00. Change any input above and every figure here is recalculated in your browser.

Inputs used

Total Commits in Periodaccepts 0–10,000,000 commits

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or fees or charges 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.

Frequently Asked Questions

Is a higher commit frequency always better?

Not necessarily — commit frequency reflects activity, not quality or value delivered. Squash-merging workflows naturally show fewer, larger commits than teams that commit incrementally.

How do I get commit counts and dates from Git?

Use `git log --since=<date> --oneline | wc -l` for a total count, or `git log --format=%ad --date=short` piped into a grouping script to see daily/weekly breakdowns.

What causes a sudden drop in commit frequency?

Common causes include holidays, a team between sprints, contributors blocked on a dependency, or the project shifting to a maintenance phase with fewer active changes.

Should I compare commit frequency across repos?

Only cautiously — team size, commit granularity (squash vs. many small commits), and workflow conventions all affect raw frequency, so it's most useful as a trend within one repo over time.
