What Is an Attendance Calculator?
An attendance calculator helps students quickly calculate their attendance percentage based on the number of classes attended and the total number of classes. It can also help you determine how many classes you need to attend to reach a required attendance percentage.
How to Calculate Attendance Percentage
You can calculate attendance percentage using this simple formula:
Attendance Percentage = (Classes Attended ÷ Total Classes) × 100
Example
If you attended 45 classes out of 50 total classes:
(45 ÷ 50) × 100 = 90%
Your attendance is therefore 90%.

How Many Classes Can I Miss?
If your current attendance is already above your required percentage, the calculator can estimate how many additional classes you can miss while still maintaining your target attendance.
