Check each subject against the 75% exam-eligibility rule for Indian colleges. Enter classes held and attended to see your percentage, exactly how many more classes you must attend to clear the threshold, how many you can still skip, and whether a subject sits in the condonation band. Set your own threshold and floor — it runs in your browser, with nothing stored.
Below the threshold but at or above the floor = condonation band. A safe buffer (say 5%) targets a higher figure so illness or emergencies don't tip you under.

Indicative figures for planning only — not an official eligibility ruling. The threshold, the condonation band, required documents and any fee are set by your university and the relevant council (UGC, AICTE and others) and vary by programme; "classes to attend" assumes you attend every class from now and that no classes are cancelled. Confirm the exact rule with your institution before relying on any result.
The rule
Across Indian higher education, a student is generally expected to have at least 75% attendance to be eligible to sit the end-semester examination. The figure is not an arbitrary college choice — it is anchored in the University Grants Commission (UGC) regulations and the All India Council for Technical Education (AICTE) handbook for approved programmes. In AICTE-approved colleges, which covers essentially every institution awarding a valid technical degree, the 75% minimum is expected per subject, per semester — not as one blended figure across the whole timetable.
The percentage for a subject is simply the classes you attended divided by the classes that were held, expressed as a percentage:
Because the rule is applied subject-wise, a strong overall average can still hide a single subject that has slipped below the line — and it only takes one short subject to be detained from that paper. This calculator therefore tracks every subject independently and rolls them up into an overall figure for context.
If a subject is short, the question is how many consecutive classes you must attend from now to climb back to the threshold. Assuming you attend every future class, the number is the smallest whole number of classes that satisfies:
The tool solves this for you. If you are already above the threshold it does the inverse — how many classes you could still miss before you drop to the line — so you can plan around an unavoidable absence without guessing.
Falling below the threshold does not always mean automatic detention. Most universities run a condonation process that can permit a short student to still sit the exam, typically within a band — commonly around 65% to 75% — and usually on a valid ground such as a medical certificate, often with a condonation fee. The exact band, the documents required and the fee differ between universities and councils. This calculator flags when a subject sits inside the band you set, but it cannot grant condonation — only your institution can.
If you drop below the minimum without condonation, the formal outcome is usually detention (often marked "DT" or "shortage" on the marksheet). In practice that can mean you are barred from the end-semester exam in that subject, the subject behaves like a backlog for placement filters, and you re-register for it later — which can push graduation back. Because a detained subject is excluded from that semester's grade computation, it also distorts your SGPA and, in turn, your CGPA. The honest takeaway: track attendance monthly and keep a buffer rather than chasing exactly 75% at the end.
Just need a quick percentage? For a plain attendance percentage and "how many can I miss" without the college eligibility framing, use the attendance percentage calculator. To see how a detained subject hits your grades, try the CBCS CGPA & credit calculator.
From calculator to live system
A calculator checks one student after the shortage has happened. CampusAlly's attendance module runs the same subject-wise 75% eligibility logic on live data for every student — marking lecture-wise attendance, surfacing short subjects on the HOD and class-coordinator dashboard early, sending consent-based shortage alerts to parents over DLT-registered templates, and handing the cleared eligibility list straight to the examination module so exam forms and hall tickets only open for eligible students. Condonation cases are tracked with the documents attached, not chased on WhatsApp.

About this calculator
Indian higher-education norms expect a minimum of 75% attendance for a student to be eligible to sit the end-semester examination. The figure is anchored in the UGC's regulations and the AICTE handbook for approved programmes, and AICTE-approved colleges are expected to enforce it for each subject, each semester. A student below the threshold without condonation can be detained from that subject's exam.
Attendance percentage = (classes attended ÷ classes held) × 100. This calculator computes it per subject, because the 75% rule is usually applied subject-wise rather than as a single overall figure.
If you are below the threshold, the number of additional consecutive classes you must attend is the smallest whole x that satisfies (attended + x) ÷ (held + x) ≥ 0.75. The calculator does this for you and shows the exact number, assuming you attend every one of them from now on.
Condonation is a university process that may allow a student who falls short of the threshold to still sit the exam, typically within a band (commonly 65% to 75%) and usually requiring a valid reason such as a medical certificate and sometimes a fee. The band, documents and fee vary by university, so confirm your own institution's rule. This tool only flags when a subject sits in that band.
75% is the common norm, but some programmes and councils set different minimums (certain professional courses are stricter). The threshold and the condonation floor in this calculator are both editable so you can match your own university's regulations.
