How to Use Negative Marks Calculator
The Negative Marks Calculator instantly computes your net exam score when wrong answers carry a penalty. Whether you are practicing for a competitive entrance exam, a government test, or an online quiz, this calculator tells you exactly what you earned and what you lost.
- Enter the total number of questions — This sets the scale and maximum possible score.
- Fill in correct, wrong, and unattempted counts — The three values should add up to the total. If you leave a field blank it is treated as zero.
- Set marks per correct answer — Most exams use 1 or 2 marks per question; enter whatever your exam specifies.
- Choose a penalty preset — Select 1/4, 1/3, 1/2, or 1 to match common negative-marking rules, or pick Custom to type in any deduction amount. The Negative Marks Calculator updates instantly.
- Read the results — You will see your final score, maximum possible score, percentage, marks gained, marks deducted, and the score you would have achieved with no wrong answers.
The “Score If No Wrong Answers” row is particularly useful: it shows what your raw score would be if all your attempts had been correct, helping you understand whether a guessing strategy is helping or hurting.
Formula & Theory - Negative Marks Calculator
The Negative Marks Calculator applies the following standard formula:
Final Score = Correct × Marks_per_Correct − Wrong × Penalty_per_Wrong
Max Marks = Total_Questions × Marks_per_Correct
Score % = Final Score / Max Marks × 100
Correct Rate = Correct / Total_Questions × 100
Wrong Rate = Wrong / Total_Questions × 100
Unattempted % = Unattempted / Total_Questions × 100
Accuracy = Correct / (Correct + Wrong) × 100| Symbol | Meaning |
|---|---|
| Correct | Number of questions answered correctly |
| Wrong | Number of questions answered incorrectly |
| Marks_per_Correct | Points awarded for each correct answer |
| Penalty_per_Wrong | Points deducted for each wrong answer |
Common Penalty Rules
| Exam type | Typical penalty |
|---|---|
| UPSC Civil Services (India) | 1/3 of marks |
| SSC CGL / CHSL | 0.50 (for 2-mark questions) |
| JEE Main MCQ | 1 mark per wrong |
| CAT | 1/3 of marks |
| SAT (pre-2016) | 1/4 mark per wrong |
Unattempted questions carry no penalty in most exams, which is why selectively skipping uncertain questions is a valid strategy.
