Attendance formula
Current attendance = attended classes / total classes x 100
If your current attendance is above the requirement, the calculator estimates how many future classes you can miss while staying eligible. If it is below the requirement, it estimates how many consecutive classes you need to attend.
Step-by-step example
- Total classes: 20
- Attended classes: 16
- Required attendance: 75%
- Current attendance = 16 / 20 x 100 = 80%
- Because 80% is above 75%, you may be able to miss some future classes and still meet the requirement.
When to use this calculator
- Use it when you want a quick planning estimate before checking your official school system.
- Use it to compare what changes when grades, weights, attendance requirements, or study hours change.
- Use it as a private browser-based tool because inputs are not stored by StudyCalc AI.
Common mistakes
- Mixing points and percentages without converting them first.
- Using the wrong grading scale for your school or country.
- Forgetting that schools may round grades or apply special rules differently.
How to interpret your result
Treat the result as a planning estimate, not an official transcript, school record, admissions conversion, or guarantee of academic outcome.
