How to calculate attendance percentage is important for students in school, college, and university. Attendance percentage tells you how many classes or working days you attended compared with the total number of classes or days.
You can calculate it manually using a simple formula or use an attendance percentage calculator online.
Attendance Percentage Formula
The basic attendance percentage formula is:
Attendance Percentage = (Classes Attended ÷ Total Classes) × 100
For example, if you attended 45 classes out of 50:
(45 ÷ 50) × 100 = 90%
Your attendance percentage is 90%.
How to Calculate Student Attendance Percentage
To calculate your student attendance percentage, follow these steps:
- Find the total number of classes held.
- Count the classes you attended.
- Divide classes attended by total classes.
- Multiply the answer by 100.
Example
Suppose a college student attended 72 classes out of 80.
Attendance = (72 ÷ 80) × 100
Attendance = 90%
This method can be used for school attendance, college attendance, and university attendance.
Calculate Attendance from Present and Absent Days
If you know your present and absent days, first calculate the total days:
Total Days = Present Days + Absent Days
Then use:
Attendance % = (Present Days ÷ Total Days) × 100
For example:
- Present Days = 36
- Absent Days = 4
- Total Days = 40
Attendance = (36 ÷ 40) × 100 = 90%
How to Calculate 75% Attendance
If you attended 30 classes out of 40:
(30 ÷ 40) × 100 = 75%
So, your attendance is 75%.
To maintain a required attendance level, always check your school’s, college’s, or university’s official attendance policy.
How to Calculate 80% Attendance
For example, if you attended 40 out of 50 classes:
(40 ÷ 50) × 100 = 80%
You can use the same attendance calculation formula for any number of classes.
Monthly Attendance Percentage
For monthly attendance percentage, count the present days and total working days for that month.
Monthly Attendance % = (Present Days ÷ Total Working Days) × 100
For example, if there were 24 working days and you attended 21:
(21 ÷ 24) × 100 = 87.5%
Average Attendance Percentage
For a semester or longer period, it is usually better to calculate attendance from the total classes attended and total classes held rather than simply averaging daily percentages.
Overall Attendance % = (Total Classes Attended ÷ Total Classes Held) × 100
This gives a more accurate overall attendance rate.
How to Calculate Attendance Percentage in Excel
You can also calculate attendance in an Excel attendance sheet.
If cell A2 contains classes attended and B2 contains total classes, use:
*=(A2/B2)100
For example:
- A2 = 45
- B2 = 50
- Result = 90%
This makes attendance calculation in Excel easy for students and teachers.
