Attendance percentage is how many classes you attended out of the total your institution conducted. It's the standard metric Indian schools, colleges, and universities use to decide exam eligibility.
Formula: Attendance % = (Classes Attended ÷ Total Classes Held) × 100
Example: Your college holds 60 Physics classes. You attend 45. (45 ÷ 60) × 100 = 75% — exactly at the UGC-mandated minimum. One more miss and you're below it.
The formula is simple. Tracking it accurately across multiple subjects at once is what actually trips students up — and it's what this tool handles automatically.
Step 1 — Note total classes conducted so far in the subject this semester. Step 2 — Count how many you actually attended. Step 3 — Divide attended by total conducted. Step 4 — Multiply by 100.
Example — Chemistry: 80 classes conducted, 55 attended. (55 ÷ 80) × 100 = 68.75%
Below the required threshold. No further bunking room — needs consistent attendance from here to recover.
The minimum across most of India's higher education system is 75%, set out in the UGC (Minimum Standards of Instruction) Regulations, 2003, Clause 5.8. Most affiliated colleges enforce it strictly as exam eligibility criteria.
In practical terms: if your college holds 100 classes in a subject this semester, you need at least 75 attended to sit the end-semester exam.
Most universities apply this per subject, independently. Strong attendance in one subject gives you no cover in another — track each one separately.
Regional variations: Many state universities across Karnataka, Maharashtra, Tamil Nadu, Telangana, and Andhra Pradesh enforce the percentage strictly per subject. Some allow conditional exam appearance between 65–74% with valid medical documentation — entirely at the institution's discretion, never guaranteed. Check your own college's academic regulations before relying on this.
Add a Subject — Enter subject name, classes attended, classes conducted, and required percentage. If the subject has a fixed total (e.g., 25 classes for the semester), enter that too — otherwise leave it blank and the tool assumes classes are ongoing. Default required percentage is 75%; adjust it per subject if your institution needs 80%.
Read Your Results — Three outputs per subject: current percentage, a status badge (Green/Yellow/Red), and the exact number of classes you can still bunk.
Track All Subjects Together — Add every subject you're enrolled in. The tool builds a weighted overall attendance figure across all of them.
Update Regularly — As new classes happen, update your numbers. Weekly or monthly checks catch problems before they compound.

Exam Detention — The main risk: your college blocks you from the semester exam. You lose that semester's exams and may repeat the year or subject, depending on institution policy.
Internal Assessment Impact — Many colleges cut internal assessment marks for low attendance, even if you're later allowed conditional exam entry.
Medical Certificate & Condonation — Most colleges allow up to 10% relaxation for genuine medical emergencies with valid documentation. A student at 65–74% may get conditional appearance after submitting a certificate. This is at the college's discretion — not a guaranteed right under any regulation.
Condonation Committees — Some universities run formal committees where students appeal with documented reasons: hospitalisation, family emergency, sports representation. Outcomes vary by institution.
If your subject has a fixed total number of classes, recovery works differently — the calculator checks how many of the remaining classes you need, not how many more classes will be added. Enter the total classes for the subject and the tool switches to this fixed-total calculation automatically.
Bunkable Classes answers: how many more classes can I skip without dropping below my required percentage?
Formula: Bunkable Classes = floor( (Attended × 100 − Required% × Total) ÷ Required% )
Floor rounds down — you can only skip whole classes.
Worked example — Mathematics: Total conducted: 60. Attended: 50. Required: 75%.
Bunkable = floor( (50×100 − 75×60) ÷ 75 ) = floor( 500 ÷ 75 ) = floor(6.67) = 6 classes
Skip a 7th and attendance drops to 74.6% — below minimum.
If you're already below the required threshold, bunkable classes shows 0. You need to attend everything upcoming, possibly every remaining class, to climb back up.
Scenario 1 — Classes still ongoing (dynamic model): Classes Needed = ceil( (Required% × Total − Attended × 100) ÷ (100 − Required%) )
Example: 50 classes conducted, 30 attended (60%), required 75%. Classes needed = ceil( (75×50 − 30×100) ÷ 25 ) = ceil(750 ÷ 25) = 30 consecutive classes, no misses.
Scenario 2 — Subject has a fixed final total: Step 1: Minimum Required Attendance = ceil(Final Total × Required% ÷ 100) Step 2: Classes Needed = Minimum Required Attendance − Current Attended
Example: 25 total classes, required 75%, 10 attended. Required attendance = ceil(25 × 75 ÷ 100) = ceil(18.75) = 19 Classes needed = 19 − 10 = 9 of the remaining classes
If fewer than 9 classes remain, recovery isn't possible.
Overall % = (Total Attended Across Subjects ÷ Total Classes Across Subjects) × 100
Not a simple average of percentages — a simple average treats every subject as if it has the same number of classes, which is rarely true.
Example:
| Subject | Attended | Total |
|---|---|---|
| Mathematics | 42 | 55 |
| English | 30 | 40 |
| Chemistry | 38 | 50 |
Total attended: 110. Total classes: 145. Overall = (110 ÷ 145) × 100 = 75.86%
Averaging the three percentages directly would give a different, less accurate number. Weighted calculation is also how your institution's system actually computes it.
Averaging percentages instead of class counts. 80% in one subject and 70% in another doesn't average to 75%. Add raw class counts first, then calculate.
Forgetting practicals and labs. These often carry separate, sometimes stricter, thresholds. Add them as a separate subject entry.
Miscounting total classes. Cancelled lectures and substitution classes create confusion. Count only classes officially recorded in the attendance register — verify with your department if unsure.
Not updating regularly. A weekly update takes under two minutes and keeps your numbers reliable through the semester.
Assuming overall safety means per-subject safety. Your overall weighted figure might read 77% while one subject sits at 68%. Exam eligibility is assessed per subject, not on the combined figure.
Works for students at VIT University, SRM Institute of Science and Technology, Loyola College, Anna University, University of Mumbai, Savitribai Phule Pune University, Osmania University, VTU, JNTU, University of Delhi, Amity University, Manipal Academy of Higher Education, and any institution following UGC or CBSE attendance guidelines.
Indian universities typically run 90–100 instructional-day semesters, with attendance registers closed and submitted before the exam window opens. Once closed, there's no recovering. Most students aren't tracking this actively until it's already too late.
Checking monthly takes minutes. A shortfall caught in Month 2 is manageable; the same shortfall caught in Month 5 often isn't, given how few classes remain.
Low attendance also affects internal assessment marks, sports/cultural leave approvals, scholarship eligibility at government-funded institutions, and sometimes hostel access — well beyond just exam eligibility.

75% per subject is the standard, per UGC Clause 5.8. Some colleges allow conditional appearance between 65–74% with documentation, at their own discretion.
75% per subject as baseline; many colleges apply 80% for practicals specifically. Set required percentage per subject to match your college's exact rule.
Theory: 75% minimum. Practicals and clinicals: 80% minimum, under the NMC's CBME Regulations, 2023. Add theory and practical as separate entries.
Most state-level boards require 80%, with practicals tracked separately and held to stricter standards. Check your specific state board.
CBSE and ICSE apply attendance thresholds for board exam eligibility, generally in the 75–80% range depending on board and state — confirm with your school's specific circular. [VERIFY: exact current CBSE circular percentage — not confirmed in this pass]
Most companies expect 95%+ attendance. HR teams use the identical formula — working days attended over total scheduled working days.
Always verify your specific institution's policy. Rules vary by school, college, state, and country. When in doubt, ask your academic advisor or HR manager.
✅ Green (Safe) — At or above required percentage. Safe to bunk the shown number of classes.
⚠️ Yellow (Warning) — Between 65% and your required percentage. Attend more — no safe bunking at this level.
❌ Red (Critical) — Below 65%. Serious risk of ineligibility. Attend immediately.

Add your subjects, check where you stand, and see exactly how many classes you can afford to miss. The earlier in the semester you start, the more room you have to fix a shortfall before it becomes an exam-eligibility problem.
(Classes Attended ÷ Total Classes Conducted) × 100. Attending 38 of 50 classes gives (38 ÷ 50) × 100 = 76%.
floor((Attended × 100 − Required% × Total) ÷ Required%). Returns the exact number of future classes you can miss while staying at or above your required percentage. If you're already below the minimum, it returns 0.
Enter that value in the Final Total Classes field. The calculator computes minimum required attendance as ceil(Final Total × Required%) and shows how many of the remaining classes you must attend. Leave it blank if classes are ongoing.
You must attend at least 75 of every 100 classes conducted to stay eligible for semester exams, per UGC Clause 5.8. The calculator shows instantly whether you're safe, how close you are to the boundary, and how many classes you can still miss.
At 60% after 50 total classes, you'd need the next 30 consecutive classes without a miss. Formula: ceil((Required% × Total − Attended × 100) ÷ (100 − Required%)). Catch it early — recovery gets harder every week you wait.
Risk of exam detention, plus many colleges cut internal assessment marks for low attendance. Condonation of up to 10% is possible with valid medical documentation, but it's at the institution's discretion — never guaranteed.
Yes. Set it independently per subject — 75% for some, 80% for others. Bunkable classes and status badges calculate separately for each. Useful for AICTE-affiliated programmes where theory and practical thresholds differ.
Total classes attended across all subjects ÷ total classes conducted across all subjects × 100 — weighted, not averaged. This matches how institutions actually calculate it.
No. Saved only in your browser's localStorage. Never sent to a server. Clearing browser data erases it.
Yes, between 1% and 100%, per subject. Default is 75%.
Yes. Update weekly or monthly as classes happen — the calculator recalculates instantly so you always know where you stand before registers close.
