Attendance Rules Guide

75% Mandatory Rule: Most universities (UGC, AICTE, ABET) require minimum 75% attendance to appear in semester exams.
Medical Condonation: Shortages between 65% - 74% can often be condoned with formal medical certificates or approved college club duty leaves.
Safe Margin Buffer: Always maintain at least a 2–3 class buffer above your target cutoff to account for sudden illness or emergencies.

College Attendance & Safe Bunk Calculator (75% & 80% Rule Forecaster)

Everyday Used Apps Attendance & Safe Bunk Calculator is a free, privacy-focused academic planning tool for college and university students. It calculates the exact number of classes you can safely miss (bunk) without dropping below university attendance cutoffs (75%, 80%, or 85%), or calculates how many consecutive recovery lectures you must attend to clear attendance shortages and sit for semester exams.

How to Calculate Attendance & Safe Bunks in 4 Steps

Set Required Target %

Select your university's minimum mandatory threshold (75% standard, 80%, 85%, or a custom percentage).

Enter Attended & Total Classes

Input your attended lectures and total conducted lectures per subject, or use the +1/-1 quick log buttons after every class.

Read Real-Time Bunk/Recovery Quota

The tool calculates either: (A) Safe Bunks remaining, or (B) Number of mandatory consecutive classes needed to cure shortages.

Simulate Future "What-If" Classes

Test scenarios (e.g. "What if I miss the next 4 lab sessions?") to see your projected percentage before taking time off.

Mathematical Formulas Used

Scenario	Condition	Mathematical Formula
Safe Bunk Allowance	Current % ≥ Target %	`Safe Bunks = Math.floor((Attended - (Target / 100) * Total) / (Target / 100))`
Shortage Recovery Needed	Current % < Target %	`Classes Needed = Math.ceil(((Target / 100) * Total - Attended) / (1 - (Target / 100)))`
What-If Projected %	Future Planning	`Projected % = ((Attended + FutureAttended) / (Total + FutureTotal)) * 100`

Frequently Asked Questions

What is the 75% attendance rule in colleges?

Most universities and educational boards mandate a minimum of 75% attendance across all subjects to be eligible to appear for final semester examinations. Falling below 75% often results in being debarred, marked as "detained", or requiring special medical condonation.

How does the Safe Bunk math work?

When your attendance is above the threshold, each class you miss increases the total conducted lectures without increasing attended lectures. Our formula computes the exact maximum number of misses that leaves your ratio at or above 75.00%.

If I am at 68% attendance, can I recover to 75%?

Yes! Enter your current numbers and the calculator will display the exact count of consecutive classes you must attend without missing a single one to reach 75%.

Is my subject and attendance data stored privately?

Yes! All subject names, attended counts, and total class numbers are stored 100% locally in your device browser via LocalStorage. No data is ever uploaded to a server or tracked.
