Attendance Calculator

Calculate your current class attendance percentage, determine the exact number of consecutive lectures needed to reach mandatory 75% or 80% criteria, and calculate how many classes can be safely skipped.

University Grants Commission (UGC) and AICTE regulations mandate a minimum 75% attendance threshold for students to appear in end-semester university examinations. Calculating your current attendance percentage and projecting future class requirements prevents semester debarment while allowing safe planning for medical leaves.

UGC & AICTE Mandatory Semester Attendance Regulations

75% Mandatory Attendance Minimum (65% with Medical Condonation)

Mathematical formulas: Current % $= \left(\frac{\text{Attended}}{\text{Total}}\right) \times 100$. Required consecutive classes to reach target $T$: $N = \left\lceil \frac{T \times \text{Total} - \text{Attended}}{1 - T} \right\rceil$. Safe skips when above target: $M = \left\lfloor \frac{\text{Attended} - (T \times \text{Total})}{T} \right\rfloor$.

Attendance Percentage Formula

Attendance % = (Classes Attended ÷ Total Classes) × 100

Attendance percentage is calculated by dividing the number of classes attended by the total number of classes conducted and multiplying the result by 100.

Example Calculation

Input: Classes Attended: 54, Total Classes: 72

Output: Attendance = (54 ÷ 72) × 100 = 75%
