Many colleges across India strictly follow the 75% attendance rule, which means that students must attend at least 75% of their total classes to be eligible for exams. Falling below that percentage often leads to detention, loss of internal marks, or being barred from semester exams.

If a 75% attendance per subject is compulsory in a college, the total number of days are 90 and there are 5 subjects in total, how many days can a student bunk without getting his attendance less than 75%?
If you’ve ever wondered,
“How many days can I bunk and still maintain 75% attendance?”
then this article will explain the full calculation in simple words.
75% Attendance Rule Explained: How Many Days Can You Bunk in College?
📘 Scenario: 90 Total Days, 5 Subjects
Let’s assume your college has:
- Total working days = 90 days
- Total subjects = 5
- Minimum required attendance = 75% per subject
Step 1: Understanding the Formula
The basic formula for attendance percentage is:
\(\textbf{Attendance Percentage} = \left( \frac{\text{Days Present}}{\text{Total Working Days}} \right) \times 100
\)
This means your attendance percentage is calculated by dividing the number of days you were present by the total number of working days, and then multiplying by 100.
To find how many days you must attend to maintain 75% attendance, rearrange the formula as:
\(\textbf{Days Present} = \frac{75}{100} \times \text{Total Working Days}
\)
So, if your college has 90 total working days, the calculation will be:
\(\textbf{Days Present} = \frac{75}{100} \times 90 = 67.5 \approx 68
\)
✅ You must attend at least 68 days to maintain 75% attendance.
Step 2: Calculate the Minimum Days to Attend
Days Present=0.75×90=67.5
Since you can’t attend “half a day,” round it up to 68 days.
✅ You must attend at least 68 days in each subject.
Step 3: Calculate How Many Days You Can Bunk
Days You Can Bunk=Total Days−Days Present
Days You Can Bunk=90−68=22 days
👉 That means you can bunk 22 days per subject without your attendance dropping below 75%.
Step 4: If Attendance Is Calculated Subject-Wise
Most colleges track attendance per subject, not overall.
That means even if you attend all 90 days but skip one subject’s class repeatedly, your attendance in that subject may still drop below 75%.
Example:
If each subject has 18 classes per month (approx.), and you attend only 14,
(14÷18)×100=77.7% attendance
That’s safe.
But if you attend only 12,
(12÷18)×100=66.6%
You’ll fall below the required percentage.
Step 5: Why 75% Attendance Is Important
Maintaining 75% isn’t just a rule — it’s often a mandatory requirement by universities (like UGC and AICTE) to:
- Encourage regular participation in classes.
- Ensure students complete the minimum contact hours.
- Improve overall academic performance.
Some colleges even require medical certificates or Dean’s approval if you fall short.
Quick Reference Table
| Total Working Days | Attendance % | Minimum Days to Attend | Days You Can Bunk |
|---|---|---|---|
| 90 days | 75% | 68 days | 22 days |
| 100 days | 75% | 75 days | 25 days |
| 120 days | 75% | 90 days | 30 days |
| 180 days | 75% | 135 days | 45 days |
Tips to Maintain 75% Attendance
✅ Try not to bunk more than one day per week.
✅ Keep a record of your attendance (many colleges share it online).
✅ If you fall short, attend extra lectures, seminars, or make-up classes.
✅ Avoid unnecessary absences — save them for genuine needs or emergencies.
💡 Final Answer
If your college requires 75% attendance per subject,
and there are 90 total working days,
then you can bunk 22 days (and attend at least 68 days) in each subject.
Always remember — missing too many lectures might seem fun now,
but falling short of attendance can cost you your exams or grades later!
