+4 / -1. 180 questions, 720 marks. +4 for a correct answer, -1 for a wrong one, 0 if left blank. If NTA later declares more than one option correct, +4 is awarded to anyone who marked any of the correct options.
Enter your correct and wrong answer counts to see your net score after negative marking.
Should you guess? On this scheme, a single blind guess among 4 options is worth about +0.25 marks - slightly favourable, and ruling out even one option makes it clearly worth attempting.
This is your estimated raw score before any normalization, percentile, or rank the exam applies (JEE Main, for example, converts raw marks to percentiles across sessions). Marking schemes change by cycle - confirm against the exam's current official information bulletin before relying on the number.
| What it computes | Net score = (correct × marks/correct) - (wrong × penalty/wrong) |
| NEET / JEE Main | +4 correct, -1 wrong |
| UPSC Prelims | one-third of the question's marks per wrong (GS -0.667, CSAT -0.833) |
| SSC CGL Tier 1 | +2 correct, -0.5 wrong |
| Bank (IBPS / SBI) | +1 correct, -0.25 wrong |
| Unattempted questions | No penalty |

Negative marking is a penalty subtracted from your total for each wrong answer, used by most Indian competitive exams to discourage blind guessing. You gain marks for correct answers, lose a fixed fraction for wrong ones, and neither gain nor lose anything for questions you leave blank. The size of the penalty differs by exam, which is why a single "negative marking calculator" has to let you pick the scheme.
Because the penalty is applied per wrong answer, accuracy matters as much as the number of questions you attempt: two students who attempt the same count can end up with very different scores if one guesses carelessly on a heavy-penalty exam like UPSC.
The formula is: net score = (correct × marks per correct) - (wrong × marks deducted per wrong).
Worked example (NEET, +4 / -1). A student answers 130 questions correctly and 30 incorrectly, leaving 20 of the 180 blank: 130 × 4 = 520 marks gained, 30 × 1 = 30 marks lost, so the net score is 520 - 30 = 490 out of 720. The 20 unattempted questions have no effect. Switch the scheme in the calculator above for JEE, UPSC, SSC, bank, or your own custom marks-and-penalty.
| Exam | Correct / Wrong | Source |
|---|---|---|
| NEET UG | +4 / -1 | NTA (neet.nta.nic.in) |
| JEE Main (Paper 1, B.E./B.Tech) | +4 / -1 | NTA (jeemain.nta.nic.in) |
| UPSC Prelims - GS Paper I | +2 / -1/3 of the marks | UPSC (upsc.gov.in) |
| UPSC Prelims - CSAT Paper II | +2.5 / -1/3 of the marks | UPSC (upsc.gov.in) |
| SSC CGL Tier 1 | +2 / -0.5 | SSC (ssc.gov.in) |
| Bank PO / Clerk (IBPS, SBI) | +1 / -0.25 | IBPS (ibps.in) / SBI |
Schemes were verified in June 2026 against each exam's current official information bulletin. Marking rules can change every cycle (for example, NTA extended JEE Main's -1 penalty to numerical questions from 2025), so always confirm against the latest official bulletin before acting on a number.
Whether a guess helps is arithmetic, not luck. For one blind guess among k options, the expected gain is (1/k × marks per correct) - ((k-1)/k × penalty per wrong). On NEET (+4 / -1) with 4 options that is 1 - 0.75 = +0.25 marks, slightly favourable. On UPSC GS it works out to exactly 0 (neutral).
The key lever is elimination: ruling out even one option shrinks the wrong-answer probability and pushes the expected value up, which is why educated guessing usually pays while pure blind guessing on a heavy-penalty exam can cost you. The calculator shows the blind-guess expected value for your selected scheme so you can decide with the numbers in front of you - it is the math, not advice.
