Calculate your exact exam score instantly with negative marking — supports 1/3, 1/4, 0.25 and custom negative marking ratios used in UPSC, JEE, NEET, MPSC, and other competitive exams.
This tool lets you enter your correct answers, wrong answers, and the exam's negative marking rule, and it works out your final score instantly — no manual multiplication, no confusion about fractions like 1/3 or 1/4.
Here's the basic idea behind how negative marking is calculated: you get positive marks for every correct answer, and a fraction of those marks is deducted for every wrong answer. Questions you didn't attempt at all are usually left untouched — no addition, no deduction.
The tricky part is usually figuring out the exact negative marking value, since different exams use different ratios. That's why this calculator lets you simply pick your exam's ratio from a dropdown, or enter a custom value if your exam uses something less common.
A 1/3 negative marking calculator is the one most aspirants search for, since this is the ratio used in UPSC Prelims. For every wrong answer, one-third of the marks allotted to that question gets deducted.
If you're looking for a negative marking calculator for UPSC, or specifically a 1/3 negative marking calculator for UPSC Prelims, this tool already has that ratio built in as a dropdown option. Just select "1/3 Negative Marking (UPSC Prelims)", enter your correct and wrong answers, and you'll get your estimated score right away. This is especially useful right after the exam, while you're comparing your answers against the official or unofficial answer key.
A 1/4 negative marking calculator, sometimes also called a 0.25 negative marking calculator, is used for exams where one-fourth of the marks are deducted for every wrong answer. This is the pattern followed in JEE Main and several other engineering entrance exams.
MPSC exams also commonly use the 1/4 negative marking pattern, so if you were searching for an MPSC 1/4 negative marking calculator, you can use the same dropdown option here — just make sure to check your specific MPSC exam's official marking scheme first, since some MPSC papers may differ slightly by post or year.
A lot of students specifically search for how to calculate NEET marks with negative marking, since NEET follows a +4 for correct and −1 for wrong marking pattern (which works out to a 1/4 ratio in terms of deduction relative to the marks awarded).
You can calculate this directly using the tool above — just set "Marks per Correct Answer" to 4 and choose the 1/4 negative marking option (or enter 1 as a custom negative value, since NEET's deduction is a flat 1 mark, not a fraction of 4).
Some exams use a heavier penalty, and if you're looking for a 2/3 negative marking calculator, you can use the "Custom Ratio" option in the calculator above. Simply work out two-thirds of your per-question marks and enter that as your custom negative marking value.
Q: How do I calculate negative marking?
A: Multiply your number of wrong answers by the negative marking value for your exam (like 1/3 or 1/4 of the marks per question), then subtract that from the marks you earned for correct answers. This calculator does that calculation for you automatically.
Q: How do I calculate 1/3 negative marking?
A: Take one-third of the marks allotted per question, multiply it by your number of wrong answers, and subtract that from your total marks from correct answers. For example, with 2 marks per question, each wrong answer deducts about 0.67 marks.
Q: How do I calculate 1/4 negative marking?
A: Take one-fourth (0.25) of the marks allotted per question, multiply it by your number of wrong answers, and subtract that from your marks earned through correct answers.
Q: How is negative marking calculated in UPSC?
A: UPSC Prelims uses 1/3 negative marking — for every wrong answer, one-third of the marks assigned to that question is deducted from your total score. Questions left unattempted are not penalized.
Q: How is negative marking calculated in NEET?
A: NEET awards +4 marks for every correct answer and deducts 1 mark for every wrong answer. Unattempted questions receive no marks and no deduction.
Q: How do I calculate marks with negative marking in general?
A: Add up marks for all correct answers, then subtract the marks lost to wrong answers based on your exam's specific negative marking ratio. This calculator handles both steps together and shows you the final score instantly.
Note: Negative marking rules can vary slightly between exam years, subjects, or exam bodies. Always cross-check the official notification or answer key of your specific exam for the exact marking scheme before relying on any calculated score.
