The Formula

Attendance = attended ÷ held × 100

Understanding the Attendance Percentage Calculator: Classes or Hours

42 classes attended out of 50 gives 84%.

Use sessions or hours consistently; institutional absence rules differ.

Worked example: 42 of 50 classes attended is 84%, leaving eight absences. You can also enter 42 attended hours out of 50 held hours when partial hours are relevant.

Frequently Asked Questions

How is the result calculated?

Attendance = attended ÷ held × 100

What assumptions should I check?

Use sessions or hours consistently; institutional absence rules differ.

Can attendance be calculated before classes finish?

Yes, but the denominator must be classes held so far for a current rate. Using all scheduled classes produces a different planning scenario. School policies on excused absences and tardiness vary.
