Attendance Calculator
Track your attendance percentage and find out how many classes you can miss while staying above the required minimum.
Calculate Your Attendance
Enter the total classes held, classes attended, and your target attendance percentage.
How Attendance is Calculated
Attendance percentage is the number of classes you attended divided by the total number of classes held, multiplied by 100. The formula is:
Attendance % = (Classes Attended ÷ Total Classes Held) × 100
For example, if your college has held 45 lectures and you attended 38 of them, your attendance is (38 ÷ 45) × 100 = 84.4%. Most colleges and universities require a minimum of 75% attendance. Some courses are stricter and require 85% or higher.
This calculator also works in reverse: enter your target percentage and remaining classes, and it tells you exactly how many lectures you can still skip — or how many you must attend — to hit your goal.

How Many Classes Can You Miss?
The table below shows the maximum lectures you can miss in a typical semester while staying at or above 75% attendance. Find your total class count, or enter your exact numbers in the calculator above.
Keep in mind that attendance is usually calculated per subject, not overall — you can be at 85% overall and still fall short in one course. If you are planning your semester, always check your syllabus for specific class attendance policies.
