The Merit Index Formula
Merit Index=Sq+(St−Sq)×Mt−MqM−Mq Variable Definitions
M:Marks obtained by the candidate (Actual raw marks for single-session, or Normalized marks for multi-session).
Mq:The qualifying marks for the General category candidate in the specific paper (set at 40).
Mt:The mean marks of the top 0.1% or top 10 candidates (whichever is higher) in that paper.
Sq:Fixed score assigned to qualifying marks (350).
St:Fixed score assigned to top marks (900).
How it works for 2026
For the 2026 recruitment cycle, the Merit Index serves as a common denominator. Since different engineering branches (Civil, Mechanical, Electrical, etc.) take different papers, the Index allows RRB to create a unified merit list for posts that accept multiple disciplines.
Important Note on Normalization:
If the exam is conducted in multiple shifts for a single group, the raw marks are first normalized using the standard RRB normalization formula before being plugged into the M variable above.
