See exactly how many marks wrong answers cost you in any exam
In short
Enter how many questions you answered correctly and incorrectly, along with the marks per correct answer and the penalty per wrong answer. The calculator returns your score and the marks lost to negative marking.
Pick an exam preset or choose Custom and enter your own marks and penalty values.
Exam preset
JEE Main Paper 1: 75 questions, +4 correct, −1 incorrect.
JEE Advanced is deliberately not a preset because its marking varies by paper and question type. Use the JEE Advanced Score Calculator instead.
Your calculated score after negative marking
This is a marks calculation only — no rank, percentile or cut-off is produced.
Formula used
NDA penalties are held at full precision (2.5 ÷ 3 and 4 ÷ 3) inside the calculation and only rounded for display.
JEE Advanced is deliberately absent: its marking varies by paper and question type, so use the JEE Advanced Score Calculator instead.
NDA penalties are held at full precision inside the calculation (2.5 ÷ 3 and 4 ÷ 3) and rounded only for display.
positiveMarks = correct × P, negativeMarks = incorrect × N, and score = positiveMarks − negativeMarks, where P is marks per correct answer and N is the penalty per wrong answer.
Correct, incorrect and unattempted must add up to the total question count, so the calculator can also report accuracy and attempt rate.
1. Choose the exam preset, or Custom for a scheme not listed.
2. Enter your correct, incorrect and unattempted counts so they add up to the total.
3. Read the score and the marks-lost figure, then copy or share the result.
Positive marks are 50 × 4 = 200 and negative marks are 10 × 1 = 10, so the score is 190. Ten wrong answers cost 10 marks directly, on top of the 40 marks not earned.
The marks-lost figure is exactly the penalty arithmetic for the wrong answers you entered. It is not a judgement about guessing strategy, and Rank Sarthi does not claim an optimal number of attempts.
Presets follow the official rules published by NTA for JEE Main and NEET and by UPSC for NDA, versioned as JEE_MAIN_2026, NEET_UG_2026 and NDA_2026. For any other exam, use Custom and enter the rule printed in your own information bulletin.

Preset marking rules come from official NTA and UPSC documents only.
