Attendance Calculator
📅 Attendance Calculator
Most colleges set a minimum attendance percentage (commonly 75%) to sit for exams. This tells you exactly how many more classes you can afford to skip — or need to attend — to stay above that line.
This assumes the total class count entered is the final total for the term — if more classes are still scheduled, recalculate periodically as that total grows, since the safe-to-skip number shifts with it.
Frequently Asked Questions
How is the 'classes I can skip' number calculated?
It works out how many additional classes you could miss going forward while your attended-to-total ratio stays at or above the required percentage, assuming the total class count you entered is correct.
What if I'm already below the required percentage?
The calculator shows how many additional classes you'd need to attend consecutively (with no further misses) to bring your percentage back up to the minimum.
Does this account for medical or approved leave separately?
No — enter whatever your institution's official attendance register shows, since approved-leave policies vary by college and this tool only works with raw attended/total numbers.
