UNDERSTAND THE NUMBERS

Attendance percentage, explained simply

Attendance percentage shows the share of conducted classes you attended. It is a planning estimate, not a replacement for your institution’s official record. Schools may count labs, excused absences, make-up classes, or credit hours differently.

How attendance is calculated

Attendance % = Classes attended ÷ Classes held × 100

If 30 classes were attended out of 40 held, the result is 30 ÷ 40 × 100 = 75%.

Reaching a target

When you are below target, the tool adds future attended classes to both sides of the fraction until the target is reached. It always rounds up because you cannot attend part of a class.

Safe absences

When you are above target, safe absences are the largest whole number of future missed classes that keeps your attendance at or above the target. The answer rounds down for safety.

Five worked examples

Example 1

30 attended of 40 held • 75% target

Current: 75.00%. You may safely miss 0 future classes at the current target.

Example 2

35 attended of 50 held • 75% target

Current: 70.00%. Attend 10 consecutive classes to reach the target.

Example 3

54 attended of 60 held • 75% target

Current: 90.00%. You may safely miss 12 future classes at the current target.

Example 4

35 attended of 48 held • 75% target

Current: 72.92%. Attend 4 consecutive classes to reach the target. With 20 classes remaining, the maximum possible result is 80.88%.

Example 5

42 attended of 70 held • 85% target

Current: 60.00%. Attend 117 consecutive classes to reach the target. With 10 classes remaining, the maximum possible result is 65.00%.

How to improve low attendance

  • Verify your official record and correct errors early.
  • Prioritize subjects furthest below their individual target.
  • Attend consecutive sessions; new absences make recovery slower.
  • Ask the department how labs, medical leave, and cancelled classes are counted.
  • Use the subject tracker after every class, not only before exams.

Important limitations

The calculator assumes every class has equal weight and uses the numbers you enter. It cannot know your university’s exemptions, rounding rules, attendance freezes, or disciplinary policy. Always confirm important decisions with your institution.
