Enter your attendance details to see results
The attendance calculator helps you track your class attendance and plan ahead. Enter your total number of classes held, the number you attended, and your target percentage. It calculates whether you're above or below your target and tells you exactly how many classes you can miss or need to attend next.
Attendance % = (Classes Attended / Total Classes) × 100
Classes you can miss = (Attended × 100 − Target × Total) / Target
Classes needed = (Target × Total − Attended × 100) / (100 − Target)
