Introduction

For scholars, grades are further than just letters or figures; they reflect the effort, understanding, and consistency of learning. Among the most common terms in academics are GPA and CGPA . While both indicate performance, various scholars struggle to understand the difference between GPA and CGPA.

This companion explains everything you need to know, including how to calculate them, convert scores, and use tools like a GPA/ CGPA Calculator to make academic planning easier.

What is GPA?

GPA, or Grade Point Average, measures your performance in a single semester or term. It's generally on a scale of 0 to 4 in most countries, but some universities use a 10-point scale. GPA provides a snapshot of your performance for that period, showing how well you have grasped the subjects you studied.

How to Calculate GPA

To calculate GPA by hand, follow these steps:

Give a number to each grade: A = 4, B = 3, C = 2, D = 1, F = 0.
Multiply the grade number by the credit hours for that course.
Add up all these numbers.
Divide the total by the total credit hours. This gives your GPA.

Formula:

GPA = ∑(Grade Point×Credit Hours)/Total Credit Hours

For example, if you scored:

A in a 3-credit course → 4 × 3 = 12
B in a 4-credit course → 3 × 4 = 12
Total grade points = 24
Total credits = 7

GPA = 24 ÷ 7 ≈ 3.43

What is CGPA?

CGPA, or Accretive Grade Point Average, measures your overall academic performance across multiple semesters. It's basically the average of all your GPAs from every semester of your course. While GPA gives a short-term view, CGPA provides a long-term perspective on your academic consistency.

How to Calculate CGPA

Calculate the GPA for each semester.
Add all semester GPAs together.
Divide by the total number of semesters.

Formula:

CGPA = ∑Semester GPAs/Number of Semesters

For example, if your GPAs for 4 semesters are: 3.2, 3.5, 3.8, and 3.6, then:

CGPA = (3.2 + 3.5 + 3.8 + 3.6) ÷ 4 = 3.525

A gpa to cgpa calculator online can make this process quick and accurate.

Key Differences Between GPA and CGPA

Feature	GPA	CGPA
Meaning	Average of grades in one semester	Average of grades across all semesters
Scope	Short-term performance	Long-term performance
Purpose	Measures semester-wise understanding	Measures overall academic consistency
Calculation	Sum of grade points × credits ÷ total credits	Sum of all semester GPAs ÷ number of semesters
Impact	Used for semester results, scholarships	Used for final transcripts, higher education, jobs

Converting CGPA to Percentage

Sometimes, universities, recruiters, or scholarship committees prefer percentage scores instead of CGPA. The most common formula is:

Percentage=CGPA×9.5

For example:

CGPA 8.0 → 8 × 9.5 = 76%
CGPA 9.2 → 9.2 × 9.5 = 87.4%

Different institutions may use slightly different multipliers, so always confirm with your school. Using a CGPA to percentage tool online is a convenient way to avoid mistakes.
