GATE reports a score out of 1000 rather than raw marks. The official formula scales your marks between the qualifying marks (score 350) and the mean of the toppers (score 900). Enter the three values to estimate your score.

GATE score: S = Sq + (St − Sq) × (M − Mq) ÷ (Mt − Mq)
GATE results show three numbers: raw or normalised marks out of 100, an all-India rank and a GATE score out of 1000. PSUs shortlist on the score, and many IITs, NITs and other institutes use it for M.Tech admissions and scholarships. This calculator estimates the score from your marks using the formula published in the GATE information brochure.
The formula places the qualifying marks at a score of 350 and the average marks of the top performers at 900, and scales everyone else linearly between and beyond these points. This lets scores be compared across years and papers of different difficulty, which raw marks cannot do.
To use it, you need your marks and two numbers published for your paper after results: the qualifying marks and the mean of the top 0.1% of candidates, or of the top 10 if that is larger.
1. Take your marks M out of 100 (normalised marks if your paper ran in multiple sessions).
2. Find the qualifying marks Mq for the paper from the official result notice.
3. Find Mt, the mean marks of the top 0.1% of candidates or top 10, whichever is larger.
4. Use Sq = 350 and St = 900.
5. Compute score = Sq + (St − Sq) × (M − Mq) ÷ (Mt − Mq).
6. Keep the result within 0 to 1000 and round to a whole number.
The formula is the equation of a line passing through (Mq, 350) and (Mt, 900). Its slope is 550 ÷ (Mt − Mq) score points per mark. If a paper is hard and toppers average only 70 while the qualifying mark is 25, each mark is worth about 12.2 score points. In an easier paper where toppers average 85 and the qualifying mark is 30, each mark is worth only 10. So the same raw marks can mean a higher score in a tougher year.
Raw marks depend on paper difficulty, which varies from year to year and paper to paper. Anchoring to the qualifying cut-off and to the average of the very best performers ties the score to the candidate pool instead. Averaging the top 0.1% rather than using the single top mark makes the upper anchor stable against one outlier. The scaling is linear, so the order of candidates never changes; only the spacing does.
When a paper is held in more than one session, question sets differ in difficulty. GATE first converts each candidate's raw marks into normalised marks using statistics of each session, so that candidates in a harder session are not disadvantaged. The score formula is then applied to the normalised marks. If you enter raw marks from a multi-session paper, the estimate may be off by a few score points. Use the normalised marks shown on your scorecard for an accurate check.
Pranav wrote the GATE mechanical paper and his scorecard shows 48.33 normalised marks. The result notice lists 32.5 as the qualifying marks and 85.67 as the mean of the top performers.
GATE formula (Sq = 350, St = 900): Score = Sq + (St − Sq) × (M − Mq) ÷ (Mt − Mq) = 350 + 550 × (48.33 − 32.5) ÷ (85.67 − 32.5) = 513.75
Keep within 0–1000: 514
Answer: Estimated GATE score 514
Using raw marks instead of normalised marks for a multi-session paper.
Taking Mt from a different year or paper, which changes the slope.
Assuming the score is simply marks × 10.
Comparing ranks across papers instead of scores; ranks depend on the number of candidates in each paper.
Using the wrong qualifying mark; check how the brochure defines Mq for the score formula.
Estimating the GATE score before the scorecard is released.
Checking PSU shortlisting chances against past cut-off scores.
Comparing performance across years for repeat attempts.
Understanding how paper difficulty affects the value of each mark.
Where do I find Mq and Mt?
They are published by the organising IIT with the results for each paper.
Is score or rank used for PSU jobs?
Most PSUs shortlist by GATE score; IIT admissions often use score too.
