How it works
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.
Formula
Attendance % = (Classes Attended / Total Classes) × 100
Classes you can miss = (Attended × 100 − Target × Total) / Target
Classes needed = (Target × Total − Attended × 100) / (100 − Target)
How to use
- Enter the total number of classes held so far.
- Enter how many classes you have attended.
- Set your target attendance percentage (default is 75%).
- Click “Calculate” to see your results.
