How required marks are calculated

Set a target percentage and the calculator tells you the exact number of marks needed — and whether that target is still achievable given what you've already scored.

Formula
Required Marks = ⌈ (Target% / 100) × Total Marks ⌉Marks Still Needed = max(0, Required − Obtained)Achievable = Marks Still Needed ≤ Marks Available

Example — 60% Target in a 200-Mark Exam

Frequently Asked Questions

Required Marks = ⌈(Target% / 100) × Total Marks⌉. The ceiling function (⌈⌉) means fractional marks are rounded up to the next whole number — because you can't score 0.8 of a mark, you need to reach the next integer. For 60% in 200 marks: ⌈120⌉ = 120.
