Attendance Bunk Planner
Find out how many classes you can still miss — or must attend — to stay above the cut-off.
Most attendance calculators tell you a percentage you could work out yourself. The useful question is different: given where you are now and how many classes are left, how many can you still afford to miss? This planner answers that, and tells you when the cut-off has become mathematically unreachable — while there is still time to do something about it.

What the Attendance Bunk Planner does
Indian colleges typically require 75% attendance to sit an examination, though the threshold varies and some institutions apply it subject-wise rather than overall. Falling short can mean being detained, paying a condonation fee, or repeating a semester.
What makes attendance stressful is that the arithmetic changes every week. Missing three classes in week two is recoverable; missing three in the final week may not be. This tool recalculates the margin against the classes that are actually left.
How to use this tool
- Enter how many classes you have attended and how many have been held so far. Use the figures from your college portal rather than memory.
- Set the required percentage from your academic regulations — 75% is the default but confirm yours.
- Enter the classes still to be held. Multiply the remaining weeks by the number of classes per week for that subject.
- If your institution counts approved medical or duty leave as attended, enter those separately.
- Read the headline: it tells you either how many you can still miss, how many you must attend, or that the cut-off is out of reach.
Formula and method
Current % = Attended ÷ Held × 100
Total classes = Held + Remaining
Must attend = ⌈(Required % × Total classes) − Attended⌉
Can miss = Remaining − Must attend
Best possible = (Attended + Remaining) ÷ Total × 100
The result is rounded up, because you cannot attend a fraction of a class. That rounding is deliberately conservative — it never tells you that you have more margin than you do.
Worked example
Example: 48 of 68 attended, 40 classes left, 75% required
| Current attendance | 70.6% |
| Total classes for the term | 108 |
| Attendance needed at 75% | 81 classes |
| Must attend from remaining | 33 of 40 |
| Can afford to miss | 7 classes |
Currently below the cut-off, but comfortably recoverable — attending 33 of the remaining 40 classes finishes the term at exactly 75%.
What your result means
"You can miss X more" is your buffer for illness, travel and everything else. Keep two or three in reserve rather than spending it all.
"You must attend all remaining" means zero margin. One fever finishes it, so this is the point to talk to your faculty advisor rather than hoping.
"Cut-off no longer reachable" is not the end, but it does mean the route is now administrative rather than arithmetic — condonation, medical certificates, or a formal application. Every one of those has a deadline, and they close early.
Important considerations
- Many colleges apply attendance subject-wise. An 80% overall figure hides a 60% in one paper, and it is the individual subject that stops you sitting the exam.
- Labs, tutorials and practicals often carry separate attendance requirements, sometimes stricter than lectures.
- Whether approved medical leave counts as attended varies by institution. Some mark it present, some exclude the class from the denominator, some do neither.
- Attendance is frequently updated with a lag on college portals. Use the latest figure, and confirm with the subject teacher if a decision depends on it.
- Condonation is usually discretionary, capped at a fixed percentage band, and requires a fee and documentation. It is not a right.
Limitations of this tool
- It works on a single subject or a single overall figure at a time. If your college calculates attendance per subject, run it separately for each.
- It cannot know your institution's treatment of medical leave, condonation limits or holidays that reduce the number of classes actually held.
- The remaining-classes figure is your estimate. Cancelled classes, extra classes and holidays will move the answer.
Frequently asked questions
How many classes can I bunk with 75% attendance?
It depends on the total number of classes in the term, not just your current percentage. With 108 total classes at 75%, you may miss 27 in all. What matters is how many of those you have already used — enter your figures above to see the balance.
What happens if my attendance is below 75%?
Consequences vary: you may be barred from the end-semester examination, required to apply for condonation with a fee, marked as detained in that subject, or in some institutions required to repeat the semester. Your academic regulations set out exactly what applies.
Does medical leave count towards attendance?
It depends on your institution. Some mark approved medical leave as present, some exclude those classes from the total, and some grant no relief at all. Submit the certificate promptly regardless — retrospective applications are usually refused.
Is attendance calculated per subject or overall?
Most Indian universities calculate it per subject, and many additionally require a minimum overall percentage. Being safe overall does not protect you if one subject is short.
Can I improve attendance by attending extra classes?
Only if extra classes are actually held and recorded for that subject. You cannot attend another section's class to make up a shortfall unless your department explicitly permits it.
