Attendance Percentage Calculator

Enter classes held and attended to see your attendance % and how many classes you can bunk or must attend.

Most Indian colleges and universities require at least 75% attendance to be eligible to sit for semester exams — though some institutions set the bar at 65%, 80% or another figure entirely, so the minimum % below is fully editable to match your college's actual rule. This college attendance calculator is built for students who want a quick answer to "how many classes can I bunk?" or "how many classes do I need to attend to hit 75%?" without doing the math by hand. Just enter the total classes held so far, how many you've attended, and your college's minimum requirement — your current attendance percentage and a clear, live-updating takeaway appear instantly. Nothing you type is sent anywhere or stored; all calculations happen right in your browser.

This calculator follows the standard attendance-percentage rule used by most Indian colleges and universities. Some institutions apply additional rules (e.g. per-subject minimums, medical condonation, rounding conventions) that aren't reflected here — always confirm with your own college's academic office or handbook before making bunking decisions based on this tool.

Frequently Asked Questions

Why is 75% attendance required in most Indian colleges?

Most Indian universities and colleges set a 75% minimum attendance requirement as an academic regulation, often linked to UGC and AICTE guidelines, to ensure students engage consistently with coursework before sitting for semester exams. It's the most common threshold, but it isn't universal — some colleges require 65%, some 80%, and a few allow condonation down to 65-70% with a medical certificate or fee. Always check your own institution's exact rule, and adjust the minimum % field in this calculator to match it.

What happens if my attendance falls below the minimum requirement?

Consequences vary by institution, but commonly include being debarred from sitting the semester exam, being marked 'detained' for the course, having to repeat the semester or attend condonation classes, or paying a condonation fee if your college allows an exception (typically only down to 65-70%, often with a medical certificate). Some colleges also dock internal marks for low attendance. Check your college's academic handbook for the exact rule that applies to you.

Does this calculator work for any college, not just ones requiring 75%?

Yes. The minimum required attendance % field is fully editable and defaults to 75% only because that's the most common rule in Indian colleges. If your college requires 65%, 80%, 85% or any other percentage, just change that field and every result updates instantly to match your college's actual requirement.

How is the "classes you need to attend" number calculated?

If you're below the minimum, the calculator finds the smallest number of classes (Y) such that attending all of them consecutively — adding Y to both classes attended and classes held — brings your attendance to at least the minimum percentage: (attended + Y) / (held + Y) ≥ minimum%. It solves this algebraically and rounds up to the nearest whole class, since you can't attend a fraction of a class.

How is the "classes I can bunk" number calculated?

If you're already at or above the minimum, the calculator finds the largest number of additional classes (X) that could be held (and missed) while your attendance stays at or above the minimum: attended / (held + X) ≥ minimum%. It solves this algebraically and rounds down to the nearest whole class, so the shown number is always safe — one more than that would drop you below the minimum.
