Attendance Calculator

Plan toward an attendance target

Enter classes held, classes attended, and the percentage you need. The calculator reports your current attendance and estimates either how many consecutive classes you must attend or how many future classes you may miss while staying at the target.

Example

Attending 72 of 100 classes gives 72%. If your target is 75%, attending the next 12 classes without an absence produces 84 attended out of 112, which is exactly 75%.

Institution rules still apply

This is a planning estimate. Colleges may calculate attendance subject-wise, exclude approved leave, round percentages differently, or impose separate laboratory requirements. Always compare the result with the official attendance portal and academic policy.

Attendance planning with whole classes

An attendance percentage is based on classes attended divided by classes conducted, so the next possible result changes one complete class at a time. If your institution requires 75%, a displayed 74.9% may still be below the rule even when a portal rounds it to 75%. Use the calculator result based on integer classes and confirm how your institution handles cancelled, merged, laboratory, remedial and condoned sessions.

When planning absences, leave a buffer instead of targeting the exact minimum. A timetable change or an incorrectly recorded class can remove that margin. The projection assumes every future class has equal attendance weight; courses that grade lectures and practical sessions separately need separate calculations.
