Your SGPA from your results
Paste your KTU result table, or type each subject’s grade and credits.
Each line needs a KTU grade (S, A+, A, B+, B, C+, C, D, P, F, FE) followed by its credits, which is how result pages list them. The subjects go into the SGPA calculator below, where you can check and correct every row. Paste several semesters together to get your CGPA.
Official source: KTU order U.O. No. 1584/2023 (copy circulated to affiliated colleges, hosted by College of Engineering Trivandrum). SGPA = Σ(credits × grade points) ÷ Σ credits. Grade points from R6.16 of the B.Tech 2019 regulations. Last checked 1 October 2026. Enter every semester’s subjects together and the same sum gives your CGPA. The percentage next to it applies the CGPA formula to a single semester, so read it as an estimate.
