Attendance Calculator
Track your class attendance against the minimum required percentage. See your current attendance, exactly how many more classes you can safely miss, or how many you must attend in a row to recover if you're below the threshold. A traffic-light status — safe / warning / critical — tells you at a glance where you stand.

How to use
- 1
Enter classes held and attended
Type the total number of classes held so far and how many you attended. Both are whole numbers.
- 2
Set the required minimum
Enter the minimum attendance percentage your institution requires (often 75% or 80%).
- 3
Read the traffic-light status
Green (safe) = at least 5% above the minimum. Amber (warning) = within 5% of the threshold. Red (critical) = below the minimum.
- 4
See what to do next
If you're below: see how many classes you must attend in a row. If you're above: see how many more you can miss.
Common use cases
- Check whether you can skip tomorrow's lecture without dropping below 75%.
- Plan recovery after missing a week of classes due to illness.
- Track attendance across a semester to stay above the debar threshold.
Limitations
- These results are study aids only and not a substitute for your course syllabus, institutional policies or official academic advice. Always confirm deadlines, weighting and attendance rules with your instructor.
- The model treats all future classes as either attended or missed. It doesn't account for medical leave, condonation or makeup classes — check your institution's specific policy.
- 'Classes you can still miss' assumes you attend every other class from now on. If you miss more, the number drops further.
