SRM GPA Calculator: GPA, CGPA and Percentage
This SRM GPA calculator uses the SRM grade system (O, A+, A, B+, B, C) to work out semester GPA from each course's credits, combines semesters into CGPA, and converts to percentage. It suits students at Kattankulathur, Ramapuram, Vadapalani and the other SRMIST campuses under the 2021 regulations and later.

SRM University grade system and grade points
| Grade | Grade points | Marks |
|---|---|---|
| O | 10 | 91–100 |
| A+ | 9 | 81–90 |
| A | 8 | 71–80 |
| B+ | 7 | 61–70 |
| B | 6 | 56–60 |
| C | 5 | 50–55 |
| F | 0 | Below 50 (fail) |
Final marks combine continuous assessment (cycle tests, assignments, lab work) and the end-semester exam, in the proportions set for each course type. The grade then comes from the marks band above.
SRM GPA formula, explained simply
GPA = Σ (course credits × grade points) ÷ Σ credits (one semester) CGPA = Σ (all credit points) ÷ Σ (all credits) (all semesters)
Example: courses of 4, 4, 3, 3 and 1.5 credits with grades O, A+, A, B+ and O give (40 + 36 + 24 + 21 + 15) ÷ 15.5 = 8.77 GPA. Students at Kattankulathur often forget that 1- and 1.5-credit lab and value-added courses also enter the calculation; a C in a small course hurts less than in a 4-credit one, but it still counts.
How do internal marks affect SRM GPA?
Internal (continuous assessment) marks are part of the final marks that decide the grade. A strong internal score can lift a borderline end-semester result into the next band, so cycle tests matter.
SRM GPA to CGPA
CGPA is not the average of semester GPAs when credit totals differ. Enter the earlier CGPA and the total credits completed so far, and the calculator combines them properly with the current semester.
SRM GPA to percentage
The conversion commonly used for SRM transcripts is percentage = CGPA × 10, so 8.5 CGPA is 85%. If a particular employer or university asks for a different method, it will usually say so, and SRM's examination office can issue a conversion certificate.
Keep the grade cards from every semester handy: the credit totals printed on them are what the CGPA formula needs.
SRM GPA Calculator: questions people ask
How do I convert SRM GPA to CGPA?
Multiply each semester's GPA by its credits, add them up and divide by the total credits, or enter the earlier CGPA and credits in the calculator.
What is the SRM GPA to percentage formula?
The commonly used conversion is CGPA × 10; 8.2 CGPA is 82%.
Is this SRM GPA calculator valid for 2021 onwards?
Yes. It uses the O to C grade bands of the 2021 regulations and later; earlier batches should check their regulation's grade table.
How do SRM internal marks affect my GPA?
Internal marks are part of the final marks that decide each course's grade, so they directly affect GPA.
Can I use this for other SRM-group colleges?
Affiliated colleges such as those under Anna University follow Anna University's grades; use the Anna University GPA calculator for them.
