How do I calculate how many classes I can bunk?

Use the formula: Bunks = (100 * Attended - Target% * Total) / Target%. Round down to the nearest whole integer.

How many classes do I need to attend if my attendance is below 75%?

Use the formula: Required Classes = (75 * Total - 100 * Attended) / (100 - 75). Round up to the nearest whole number.

How the Attendance & Bunk Formula Works

Most universities (such as in India, Pakistan, the UK, and the US) mandate a 75% or 80% minimum attendance criteria to sit for semester examinations. This calculator accurately models how upcoming missed or attended lectures alter your overall percentage.

Bunk Formula (When Attendance > Target)

Bunks = ⌊(100 × Attended - Target × Total) ÷ Target⌋

Gives the maximum lectures you can skip safely.

Catch-Up Formula (When Attendance < Target)

Must Attend = ⌈(Target × Total - 100 × Attended) ÷ (100 - Target)⌉

Gives consecutive upcoming classes needed to recover.
