How to Calculate Negative Marking Score Online Free
In exams with negative marking, a wrong answer does not just score zero — it takes marks away. This guide shows how to calculate your final score with negative marking: the marks earned, the marks deducted and your percentage, from your attempted and wrong answers and the marking ratio. Use the free negative marking calculator below to work out your score in seconds.
How to Calculate Negative Marks — step by step
- Enter the total questions and the maximum marks for the paper.
- Enter how many questions you attempted and how many were wrong.
- Pick the negative marking ratio — 1/4, 1/3, 1/2, a full mark, or none.
- Read your final score: it updates live as you change any value.
Tips
- Marks per question is maximum marks ÷ total questions — a 500-mark paper with 100 questions is worth 5 marks per question.
- At a 1/4 ratio, each wrong answer loses one quarter of a question's marks — 1 mark if the question is worth 4.
- Your final score can be negative if the marks deducted are more than the marks earned.
Frequently asked questions
How is the final score calculated?
First the marks for one question are found by dividing the maximum marks by the total questions. Your correct answers earn that many marks each, and each wrong answer loses that amount multiplied by the negative marking ratio. The final score is the marks earned minus the marks deducted.
What does a 1/4 negative marking ratio mean?
Each wrong answer loses one quarter of the marks for one question. If a question is worth 4 marks, a wrong answer costs 1 mark.
Can my final score be negative?
Yes. If the marks deducted for wrong answers are more than the marks earned for correct answers, the final score is shown as a negative number.
