GATE Score Calculator
Calculate your GATE score from your marks obtained, check your expected rank, and see if you meet IIT, NIT, and PSU cutoff requirements
This calculator uses the official IIT GATE score formula to calculate your score from marks obtained, qualifying marks, and the mean of top 0.1% candidates. It also estimates your All India Rank, checks PSU eligibility, and shows IIT/NIT admission chances. Many IIT M.Tech programs also require a minimum CGPA of 6.5–7.0 on a 10-point scale — use our CGPA Calculator to verify your academic eligibility alongside your GATE score.
Calculate Your GATE Score
How GATE Score is Calculated — Official Formula Explained
The GATE score is calculated using an official formula that normalizes raw marks to a standardized scale of 0–1000. This ensures fairness across different years and difficulty levels.
Official GATE Score Formula
GATE Score = ((M − Mq) / (Mt − Mq)) × (Sq − 350) + 350
M — Marks Obtained
Your actual raw marks in the exam out of 100
Mq — Qualifying Marks
Cutoff for general category (typically 25 or 1/3 of max)
Mt — Mean of Top 0.1%
Average marks of top 0.1% candidates (published by IIT)
Sq — Fixed at 900
Score assigned to the mean of top 0.1% performers
Worked Example
Given: M = 65 (your marks), Mq = 25 (qualifying), Mt = 85 (top 0.1% mean)
Step 1: (M − Mq) = 65 − 25 = 40
Step 2: (Mt − Mq) = 85 − 25 = 60
Step 3: (Sq − 350) = 900 − 350 = 550
Step 4: GATE Score = (40 / 60) × 550 + 350 = 0.667 × 550 + 350 ≈ 717
Why this formula? The GATE score formula normalizes marks so that candidates in harder or easier exam versions receive fair scores. It anchors the scale so that the top 0.1% peer group always receives a score of 900, and the minimum qualifying candidate receives a score of 350. Candidates below the qualifying mark receive a score of 0.
GATE Score Normalization — Multi-Session Papers Explained
For papers conducted across multiple sessions (like CS, ECE, ME, CE, EE), GATE uses normalization to ensure fairness across different difficulty levels.
Why Normalization?
Different sessions may have slight variations in difficulty. Normalization ensures candidates who appeared in a harder session are not disadvantaged. It uses the performance of the top 0.1% in each session as a reference point.
How It Works
Before applying the GATE score formula, raw marks are normalized using a session-specific formula. The normalized marks then replace M in the main formula. This can result in candidates receiving marks slightly higher or lower than raw marks.
GATE Qualifying Marks by Category
A candidate who scores at or above their category qualifying mark receives a GATE score and is considered to have qualified GATE. Qualified candidates receive a GATE scorecard valid for 3 years.
| Category | Qualifying Marks (%) | Out of 100 |
|---|---|---|
| General / OBC-NCL | 25% (or 1/3 of max) | 25 marks |
| SC / ST / PwD | 16.67% (or 2/3 of General) | 16.67 marks |
OBC-NCL clarification: Other Backward Classes Non-Creamy Layer candidates are eligible for the same qualifying marks as general category in GATE — OBC-NCL benefit applies to reservations in admissions but not to the qualifying threshold.

GATE Score Requirements for PSU Recruitment
Many major Public Sector Undertakings use GATE scores directly for shortlisting candidates for engineering and managerial roles. PSUs announce GATE cutoffs after GATE results are declared. Candidates apply directly to PSUs using their GATE scorecard. Some PSUs also consider academic performance — use our CGPA Calculator to verify your eligibility.
| PSU Name | Discipline(s) | Approx. Cutoff | Posts Offered | Notes |
|---|---|---|---|---|
| ONGC | All engineering | 750+ | Various engineering & managerial roles | One of the highest paying PSUs |
| BHEL | ME, EE, ECE | 700+ | Graduate Engineer Trainee | Large manufacturing PSU |
| NTPC | EE, ME, CE | 750+ | Executive Trainee | National Thermal Power Corp |
| IOCL | CH, ME, CE, EE | 750+ | Engineering Assistant | Indian Oil Corporation |
| GAIL | CH, ME, EE | 730+ | Executive Trainee | Gas Authority of India |

Important notes: PSU cutoffs vary every year based on vacancies, candidate pool, and organizational requirements. Some PSUs have additional selection rounds including group discussion, technical interview, and medical examination after GATE shortlisting.
PSU applications must be submitted separately — qualifying GATE alone is not sufficient to apply to PSUs. Always check each PSU's official recruitment notification for current cutoffs and eligibility criteria.
GATE Cutoffs for IIT and NIT M.Tech Admissions
IITs conduct their own admission process (COAP — Common Offer Acceptance Portal) based on GATE scores. NITs use CCMT (Centralized Counselling for M.Tech) which is a centralized process similar to JoSAA for B.Tech.

CGPA consideration: Many IITs set a minimum CGPA (typically 6.5 or 7.0 on a 10-point scale) for M.Tech eligibility. Use our CGPA Calculator to verify your academic eligibility alongside your GATE score.
IIT interviews: Most IITs shortlist candidates based on GATE score and then conduct a written test and/or interview. Final selection depends on both GATE score (typically 70% weightage) and interview performance (30%).
GATE Score Targets and Preparation Strategy
Your preparation strategy should align with your target score range. Here are structured approaches for common target ranges.
