How to use the Attendance Calculator (75%)

  3. Set the required percentage (usually 75%).
  4. Press Calculate.

Why 75% attendance matters

Most universities and boards in India, including BPUT and Odisha's state universities, require at least 75% attendance to sit for semester exams. Falling short can mean being detained or paying a condonation fee.

The formulas

  • Current % = attended ÷ held × 100.
  • Classes you can skip = ⌊attended ÷ target − held⌋.
  • Classes you must attend = ⌈(target × held − attended) ÷ (1 − target)⌉.

Example

45 attended out of 60 is exactly 75%, so you cannot miss any class. Attend 4 more in a row and you'll be at 49/64 = 76.6%, which lets you skip one.
