Question 1

How do I calculate my attendance percentage?

Accepted Answer

Attendance % = (Classes Attended ÷ Total Classes) × 100. For example, if you attended 42 out of 48 classes: 42 ÷ 48 × 100 = 87.5%.

Question 2

How many classes can I miss?

Accepted Answer

It depends on your school's minimum requirement. If your minimum is 75%, and you have 48 total classes: you must attend at least 36 classes, so you can miss up to 12. Enter your numbers above for an instant answer.

Question 3

What is the minimum attendance requirement?

Accepted Answer

Requirements vary by institution. US colleges typically require 75-80% attendance. Some courses require 90% or higher. Check your syllabus or ask your professor for the exact requirement.

Question 4

Does attendance affect my grade?

Accepted Answer

Yes, in most courses attendance directly affects your grade — either through participation points or because missing class means missing instruction. Some professors also drop you from the course if attendance falls below the minimum.

Question 5

What if I've already missed some classes?

Accepted Answer

Enter your current absences in the 'Classes Missed' field. The calculator will tell you how many more you can miss while still meeting your minimum attendance requirement.

Question 6

Does the calculator work for semester-long courses?

Accepted Answer

Yes — enter the total number of class sessions for the entire semester (or year), your current absences, and your minimum attendance requirement. The result shows your current percentage and remaining absences allowed.

Question 7

Can I use this for high school?

Accepted Answer

Absolutely. High schools in the US and UK often have strict attendance requirements (90%+ in many districts). Enter your total school days and absences to see where you stand.
