Can I miss a class if my attendance is exactly 75%?

No. If you miss a single class when at exactly 75%, your attendance will immediately drop below the mandatory 75% threshold.

Does this calculator support duty leaves or medical leaves?

You can add approved duty leaves or medical attendance directly to your attended classes count.

Attendance Calculator

Track your attendance percentage, calculate classes needed to reach 75% or 85%, and find how many classes you can safely miss.

Your attendance is currently exactly at your 75% target. Attend the next class to stay safe.

Attendance Tracking & 75% Rule Mathematics

Calculates your current attendance percentage and determines the exact number of future classes you must attend to meet criteria or how many you can safely bunk.

Current % = (Attended / Total) * 100 | Classes Needed = Math.ceil((Target * Total - Attended) / (1 - Target)) | Bunks Allowed = Math.floor((Attended - Target * Total) / Target)

Calculation Steps

1Enter total classes conducted to date and total classes you attended.
2Compute current percentage: (Attended / Total) * 100.
3If below target criteria (e.g. 75%), calculate consecutive future lectures you must attend.
4If above target criteria, calculate how many upcoming lectures you can safely miss without dipping below threshold.

Practical Example

Scenario: Attended 48 out of 70 classes conducted, target is 75% attendance

Inputs: Attended: 48 | Total: 70 | Target: 75% (0.75)

Calculation: Current % = (48 / 70) * 100 = 68.57%. Classes needed = ceil((0.75 * 70 - 48) / (1 - 0.75)) = ceil((52.5 - 48) / 0.25) = ceil(18) = 18 classes.

Result: Current Attendance: 68.57% | Must attend 18 consecutive classes without absence

Assumptions & Disclaimers

Key Assumptions:

Future classes are attended consecutively with 100% attendance until target is reached.
Target attendance threshold is typically 75% or 85% as mandated by UGC/colleges.

Medical leave policies and institutional attendance relaxations vary by institution. Always consult your college administration or student handbook.
