Why Attendance Planning Needs More Than One Percentage
Attendance rules can affect examination eligibility, course completion, internal marks, laboratory access, or academic standing. Students often need to know not only their current percentage but also how many upcoming classes they must attend to reach a target.
A simple present-count divided by total-count formula works only when every class is weighted equally. Some institutions calculate attendance by teaching hours, subject, laboratory sessions, credit units, or officially conducted classes.
How Hemiley Calculates Attendance
Enter the number of classes attended and the total classes conducted. The calculator finds the current attendance percentage and can estimate future attendance requirements when a target is provided.
Projected results assume the entered class counts are correct and future classes are weighted in the same way. Official records may include approved leave, medical concessions, cancellations, make-up classes, subject-wise rules, or attendance-lock dates.

Frequently Asked Questions
A common formula is classes attended divided by classes conducted, multiplied by 100.
The calculator solves for additional attended classes assuming every future class increases both attended and total counts by one.
Your allowable absences depend on current attendance, future total classes, and the required threshold.
Only if your institution's policy grants attendance credit or an approved concession.
Not when the institution applies subject-wise attendance requirements. Calculate each subject separately.
The official system may use hours, subject weights, late data entry, approved leave, or other policy rules.
