Attendance Calculator
How to Calculate Required Attendance
Calculate your current percentage and determine exactly how many upcoming lectures you need to attend—or can safely miss—to satisfy academic attendance criteria (e.g., 75% or 80%).
Attendance Calculation Formulas
Current Attendance %: (Classes Attended / Total Conducted Classes) × 100
Classes Needed for Target (T%): ((T × Total Classes) - (100 × Attended)) / (100 - T)

How many classes can I miss and maintain 75% attendance?
Divide your total attended classes by 0.75, then subtract total conducted classes so far. The resulting number represents the classes you can safely skip.
Does medical or duty leave count toward total percentage?
Policies vary by institution: approved leave is typically added to your attended total or deducted from total mandatory classes based on academic rules.
Does this calculator round fractional values?
Yes, required lecture projections round up to the next integer, as universities only grant attendance in whole units.
