What is this tool?

Attendance percentage is usually classes attended ÷ classes held (or 1 − absences/total). Many courses set a minimum attendance threshold — this tool also estimates how many more absences you can take before falling below a chosen cutoff.

How to use it

  1. Enter attended/total or absences/total.
  2. Optionally set a minimum attendance threshold.
  3. See remaining absences allowed before crossing the threshold.
