What is this Tool?
The Attendance Calculator is a free student attendance calculator that helps you track your current attendance percentage and instantly find out how many more classes you can afford to miss — or how many consecutive classes you must attend to recover your attendance.
Also known as a class bunk calculator, this tool is designed specifically for Indian college students where the 75% attendance requirement is mandatory in most universities. Falling below 75% can mean being barred from examinations or not earning exam eligibility.

Frequently Asked Questions
What is a class bunk calculator?
A class bunk calculator — also called a student attendance calculator — helps you find out exactly how many classes you can skip (bunk) while staying above your college's minimum attendance requirement, usually 75%. Enter your total classes, attended classes and remaining classes to get an instant answer.
How does the 75 attendance calculator work?
The 75 attendance calculator uses a simple formula: Attendance % = (Classes Attended ÷ Total Classes Held) × 100. It then calculates the minimum classes you must attend out of the total (including remaining classes) to stay at or above 75%, and tells you how many you can safely skip.
Does this attendance calculator work for VIT and KLU students?
Yes! This free attendance calculator works for all Indian universities including VIT University, KLU (K L University), Anna University, Mumbai University, Delhi University, Pune University and any college with a 75% or other minimum attendance requirement. Just enter your college's specific percentage in the required attendance field.
What happens if my attendance falls below 75%?
Most Indian universities debar students with less than 75% attendance from appearing in semester examinations. Some colleges allow a 5–10% relaxation for medical emergencies, sports, NCC, NSS or college events with valid documentation. Always check your specific college's attendance policy.
Is attendance calculated per subject or overall?
In most Indian universities, attendance is calculated per subject — not as an overall average. You might have excellent overall attendance but be dangerously low in one specific subject. Use this calculator for each subject separately to stay safe.
What if I have medical leave?
Keep all medical certificates from a registered doctor. Most universities require these to be submitted within a specified time (usually 7 days of return). Medical leave may or may not be condoned depending on your university's rules — always check with your department.
