Attendance Percentage: Formula and Example

Formula

Attendance % = (Classes Attended ÷ Classes Held) × 100

Example

If you attended 36 classes out of 40 held:
Attendance % = (36 ÷ 40) × 100 = 90%

Our attendance impact calculator goes further by factoring in remaining classes to estimate your final percentage.
