💡 How It Works
Our attendance calculator uses a simple formula to calculate your current attendance percentage:

For example, if you've attended 20 out of 25 classes, your attendance is (20 ÷ 25) × 100 = 80%.
🗓️ Need to Attend Class Calculation
To calculate how many more classes you need to attend to reach your target percentage:

For example, if you've attended 30 out of 40 classes (75%) and need to reach 85%:
- Target = 85%
- Total Classes = 40
- Attended = 30
- Need to Attend = (85 × 40) ÷ 100 - 30 = 4
- Rounded up: You need to attend 4 more classes
The calculator helps you determine how many more classes you can safely skip while still meeting your target attendance percentage, or how many more classes you need to attend to reach your target.
