Add the total number of classes that will be held this whole term to also see how many of the remaining classes you can skip.
Enter classes attended and classes held to see your attendance percentage, how many classes you can safely skip, and how many you need to attend to recover.
This is a planning estimate. Colleges differ on what counts toward attendance (lectures vs practicals, condonation, medical or duty leave), and your institution's official attendance register is the authoritative record. Always confirm against your own college's rules before relying on a bunk-budget.
| Attendance formula | (classes attended / classes held) × 100 |
| Typical required % | 75% (AICTE norm for technical courses; most universities set 75%, some 80%+) |
| Below the requirement? | Many colleges allow condonation (often a 65-74% band) on medical or genuine grounds, at their discretion |
| What counts as attendance | Varies - lectures, tutorials, practicals; OD and medical leave handled per institution |
| Authoritative record | Your college's official attendance register, not this tool |

Most Indian universities and colleges require students to attend at least 75% of the classes held in a subject to be eligible to sit for the end-semester examination. The norm comes from university and regulator guidelines (UGC guidance for general higher education, and AICTE rules for technical programmes) and is enforced through each institution's own academic regulations, so the precise threshold and the way it is applied differ from one college to the next.
If you fall below the requirement, many institutions offer a condonation process - typically for a shortfall band such as 65-74%, on documented medical or other genuine grounds, often with a fee. Condonation is granted at the institution's discretion and is never guaranteed, so the safe assumption is that you need to hit the full requirement on your own. Always confirm the exact rule, the condonation band, and what counts as attendance against your own college's regulations.
Attendance percentage is a simple ratio: attendance % = (classes attended / classes held) × 100. "Classes held" is the total number of sessions conducted so far, not the number scheduled for the whole term.
Worked example. You attended 32 of the 40 classes held so far: 32 / 40 = 0.8, and 0.8 × 100 = 80%. Because 80% is above a 75% requirement, you currently have a buffer - the calculator above turns that buffer into an exact number of classes you can skip.
Once you are above the required percentage, you can miss classes until your attended-to-held ratio falls to the requirement. The calculator finds the largest number of upcoming classes you can skip back-to-back while staying at or above your target.
Worked example. Say you have attended 45 of 50 classes (90%) and need 75%. You can skip the next 10 classes - 45 / 60 = 75% exactly - but not an 11th, because 45 / 61 = 73.8%, below the line. The count assumes you attend every class after the ones you skip; if more classes are scheduled later, run the numbers again.
When you are below the line, every class you attend from now on raises your percentage (the numerator and denominator both grow by one), and every class you miss lowers it. The tool computes the minimum number of consecutive upcoming classes you must attend, with no further misses, to climb back to your requirement.
Worked example. You have attended 60 of 100 classes (60%) and need 75%. Attending the next 60 classes without a miss gets you to 120 / 160 = 75%. If only a handful of classes remain in the term, recovery this semester may be mathematically impossible - add your total term classes in the optional field above and the tool will tell you the best percentage you can still reach.
