75% attendance calculator
attendance % = attended ÷ total × 100
52 ÷ 60 × 100 = 86.66%
floor((100 × 52 − 75 × 60) ÷ 75) = 9
Where the 75% rule comes from
Seventy-five per cent is the attendance minimum most Indian professional colleges enforce, and this page is fixed to it. Enter your classes attended and classes held; the answer you get is either how many consecutive classes you must now attend to reach 75%, or how many you can still miss and stay at or above it. Both are whole classes, rounded in the direction that keeps you safe.
The figure is not national law. It comes from individual university ordinances and regulator guidance rather than a single statute, which is why it moves: some institutions set 70%, a few professional programmes demand 80% or 85%, and medical and nursing councils run their own higher minimums. If your department’s notice board says something other than 75, the general attendance calculator takes any requirement you enter.
Almost every ordinance that sets 75% also provides for condonation, usually of the last 10% or so — bringing an effective floor closer to 65% for students who qualify. Condonation is normally discretionary, usually costs a fee, and almost always requires an application supported by documentation: a medical certificate, proof of sport or cultural representation, or NSS and NCC duty records. The part students get wrong is timing. A request filed in week eight, while the shortfall is still forming, is a routine administrative matter. The same request filed after results are withheld is a much harder conversation.
The consequence of falling short varies more than the threshold does. Detention from the end-semester examination is the common one, meaning you sit the paper with the next batch. Others allow the exam but withhold the result, require re-registration of the subject, or apply the shortfall only to the specific subject rather than the semester. Your examination manual states which applies to you, and it is worth reading before you need it.
Attendance is normally counted per subject, so run each subject separately — an 82% aggregate can hide a 61% subject that detains you on its own. Once results are out, SGPA to percentage handles the other half of the semester paperwork.
