JoSAA Seat Matrix 2025

How to Read This Seat Matrix

The seat matrix above reflects the branch-wise and category-wise seat distribution used in JoSAA counselling, sourced from the previous year's official data and organized by institute. Each institute entry breaks down seats by program (branch), and within each program, seats are further split by quota type and reservation category. Understanding this structure helps you interpret your realistic chances more accurately than looking only at a single "total seats" figure for an institute.

For NITs, seats are split roughly 50-50 between Home State (HS) quota — reserved for candidates who completed Class 12 from that NIT's home state — and All India / Other State (AIQ/OS) quota, open to candidates from any state. This split matters enormously for admission chances: a candidate applying under their home state's NIT often has a meaningfully better shot than an out-of-state candidate with a similar or even better rank, since they're competing for a smaller, more localized applicant pool. IITs and IIITs, by contrast, do not have a home-state quota — all their seats are effectively open to candidates nationwide, with reservation only along category lines (SC/ST/OBC-NCL/EWS/PwD/Open).

Within each quota, seats are further reserved by category following government-mandated percentages: roughly 27% for OBC-NCL, 15% for SC, 7.5% for ST, and 10% for EWS (Economically Weaker Section), applied on top of the base structure, with Persons with Disability (PwD) reservation applied horizontally (meaning PwD seats are carved out within each category rather than as a separate vertical column). Female supernumerary seats — an additional allocation created specifically to improve gender diversity at NITs, IIITs, and some GFTIs — sit outside the base seat count, meaning they add to, rather than replace, the general seat pool.

When using this data to plan your JoSAA choice-filling strategy, remember that the exact number of seats in a given branch-category-quota combination can shift slightly year to year based on institute-level decisions, new branch additions, or intake revisions — so treat the previous year's matrix as a strong reference point rather than an exact guarantee for the upcoming counselling cycle. Cross-check with the official JoSAA seat matrix released closer to the counselling dates for the most current, authoritative numbers.

A practical way to use this page is to filter down to institutes and branches within your realistic rank range, then compare their total seat count across quotas and categories to estimate how competitive each option is likely to be. A branch with a larger seat count in your applicable quota and category generally offers a better chance of admission than a similarly-ranked branch with very few seats, all else being equal — seat scarcity is often a bigger driver of high cutoffs than institute reputation alone, which is why some niche branches at well-known institutes can have surprisingly tight cutoffs simply due to low seat availability.

GFTIs (Government Funded Technical Institutes) round out the seat matrix and are worth not overlooking — these state-run and centrally-supported institutes participate in JoSAA counselling alongside IITs, NITs, and IIITs, and in many cases offer good branches with comparatively higher acceptance chances for students whose ranks fall short of NIT or IIIT cutoffs. Reviewing GFTI seat availability alongside your primary NIT/IIIT choices can help you build a more complete and realistic choice list before the counselling rounds begin.
