Understand your attendance before it becomes a problem.
Attendance rules can affect exam eligibility, internal marks, course completion and academic standing. A simple percentage is useful, but students often need to know what happens next: how many classes are required to recover, or how many can be missed while remaining above the minimum.
How attendance percentage is calculated
Divide the number of classes attended by the total number of classes conducted, then multiply the result by 100.
Attendance % = (Attended Classes ÷ Total Classes) × 100
Classes needed to reach a target
When attendance is below the target, each future class you attend increases both the attended count and the total count. The calculator solves for the minimum number of consecutive attended classes required to reach the selected percentage.
Classes you can safely miss
When your attendance is already above the target, the calculator estimates how many upcoming classes can be missed before the percentage drops below the selected limit.
Common planning scenarios
Important limitations
- Institutions may calculate attendance separately for each subject.
- Laboratories, tutorials and lectures may have different attendance rules.
- Medical leave or approved exemptions may be handled separately.
- Official portal data should be treated as the final record.
