Attendance Calculator
Enter classes attended and total classes to check your attendance percentage, plus how many classes you can miss or need to attend to hit a target.
How It Works
Attendance percentage is the share of classes held that you actually attended:
Attendance % = (Classes Attended ÷ Total Classes) × 100
If you set a target attendance percentage, the calculator works out how many more consecutive classes you need to attend to reach it, or how many more you can afford to miss while staying above it.
Example
If you attended 42 out of 50 classes, your attendance is (42 ÷ 50) × 100 = 84%. With a 75% target, you could miss several more classes and still stay above the requirement.
Frequently Asked Questions
- What is a typical minimum attendance requirement?
- Many schools and colleges require around 75% attendance, but this varies by institution and course, so always check your specific requirement.
- How many classes can I miss and stay above my target?
- Enter your target attendance percentage and the calculator will estimate how many additional classes you can miss in a row while remaining at or above that target.
- How many classes do I need to attend to reach my target?
- If you're below your target, the calculator estimates how many consecutive future classes you'd need to attend, assuming total classes keep increasing as new classes are held.
- Does this calculator account for future classes I might miss?
- The 'classes needed' estimate assumes you attend every future class in the calculation window. If you expect to miss some, recalculate with updated numbers as your semester progresses.
