Srm Cgpa Calculator

Welcome to the SRM CGPA Calculator. This tool is designed specifically for students of SRM Institute of Science and Technology to accurately calculate their Cumulative Grade Point Average (CGPA) based on their semester-wise performance (SGPA). Simply enter your SGPA and the total credits for each semester to get your overall CGPA and equivalent percentage.

Understanding the SRM Grading System

SRM Institute of Science and Technology follows a 10-point relative grading system. Your performance in a course is measured by the grade you receive, which corresponds to a specific grade point. The CGPA is the culmination of these grade points, weighted by the credits of each course.

SRM Grade Points Table

Letter Grade	Grade Point	Performance
O	10	Outstanding
A+	9	Excellent
A	8	Very Good
B+	7	Good
B	6	Above Average
C	5	Average
P	4	Pass
F	0	Fail
Ab	0	Absent

How is CGPA Calculated?

The CGPA is the weighted average of your SGPAs from all semesters. The formula is:

CGPA = Σ (SGPA_i × Credits_i) / Σ Credits_i

Where:

• SGPA_i is the Semester Grade Point Average of semester 'i'.
• Credits_i is the total number of credits earned in semester 'i'.
• Σ denotes the summation over all semesters completed.

Example Calculation

Let's assume a student has completed three semesters with the following details:

• Semester 1: SGPA = 8.75, Total Credits = 20
• Semester 2: SGPA = 9.10, Total Credits = 22
• Semester 3: SGPA = 8.50, Total Credits = 21

First, calculate the total weighted points:

(8.75 × 20) + (9.10 × 22) + (8.50 × 21) = 175 + 200.2 + 178.5 = 553.7

Next, calculate the total credits:

20 + 22 + 21 = 63

Finally, calculate the CGPA:

CGPA = 553.7 / 63 = 8.79

Frequently Asked Questions (FAQ)

What is the difference between SGPA and CGPA?

SGPA (Semester Grade Point Average) reflects your academic performance in a single semester. CGPA (Cumulative Grade Point Average) is the average of your performance across all semesters you have completed, providing an overall academic standing.

How do I convert my CGPA to a percentage at SRM?

SRM provides an official formula for this conversion: Percentage = (CGPA – 0.5) × 10. Our calculator automatically computes this for you.

What is considered a good CGPA at SRM?

While this is subjective, a CGPA of 8.0 or above is generally considered good and is often a minimum requirement for many top companies during placements. A CGPA of 9.0 or above is considered excellent and opens up opportunities for premier companies, scholarships, and top universities for higher studies.

Can I improve my CGPA?

Yes. Your CGPA is a running average. By scoring a higher SGPA in upcoming semesters, you can increase your overall CGPA. Semesters with a higher number of credits have a greater impact on your CGPA, so focusing on those can be particularly effective.
