Attendance Breakdown
How The Attendance Calculator Works
Attendance is a ratio between attended classes and total classes.
Calculate current ratio
Classes attended are divided by classes held to get the current attendance percentage.
Compare with requirement
The required attendance percentage determines the minimum number of attended classes needed at the current total.
Project upcoming classes
Upcoming classes are added to the total to estimate how many must be attended to finish at or above the requirement.
Attendance Calculator FAQ
Common questions about attendance percentage, missed classes, and recovery.
How is attendance percentage calculated?
Attendance percentage is classes attended divided by classes held, multiplied by 100.
How many classes can I miss and stay above the requirement?
The calculator solves for the largest number of future missed classes that keeps attended classes divided by total classes at or above the required percentage.
What if I am already below the requirement?
The calculator shows how many consecutive classes you need to attend and whether your upcoming class count is enough to recover.
