📖 Attendance Calculator
Attendance Calculator helps students, teachers, and employees calculate their attendance percentage and determine how many more classes or workdays they need to reach a target percentage. Essential for maintaining minimum attendance requirements (e.g., 75% in most Indian schools and colleges).
📐 Attendance Formula
Attendance % = (Attended ÷ Total) × 100
Example: 35 attended out of 50 classes = (35 ÷ 50) × 100 = 70%.
📊 Required Classes Formula
Required = ⌈[(Target% × Total) - Attended] ÷ (100% - Target%)⌉
🏫 Common Attendance Requirements
- 75% - Minimum in most Indian schools (CBSE, ICSE, State Boards)
- 80% - Common for professional courses and competitive exams
- 85-90% - Required for scholarships and special programs
- 100% - Perfect attendance, often recognized with awards
