Difference between CGPA and GPA If you’ve ever looked at your academic transcript or applied for higher education, you’ve likely encountered the terms GPA and CGPA. While they are related and often used interchangeably in casual conversation, they represent distinct measurements of your academic performance. Understanding the difference is crucial for accurately tracking your progress and presenting your achievements.
This guide will break down each term, highlight their key differences, and provide clear examples to eliminate any confusion.

The Core Difference: At a Glance
The simplest way to understand the difference is to think about timeframe.
- GPA (Grade Point Average) measures your academic performance over a short, specific period, usually a single semester or term.
- CGPA (Cumulative Grade Point Average) measures your overall academic performance across all semesters or terms in your entire academic program.
Think of it like this:
- Your GPA is like your batting average in a single baseball game.
- Your CGPA is your career batting average across the entire season (or your entire career).
Both are important, but they tell different stories about your performance.
What is GPA? (The Semester Snapshot)
GPA, or Grade Point Average, is a numerical representation of your academic achievement for a specific term, typically a semester or quarter.
- Purpose: It provides a snapshot of how well you performed in a given set of courses during a short period. It’s useful for identifying trends, such as a particularly strong semester or one where you faced challenges.
- Calculation: It is calculated by taking the sum of the Grade Points earned in each course multiplied by that course’s credit hours for that term, divided by the total number of credit hours attempted that term.
- Fluidity: Your GPA can fluctuate significantly from one semester to the next based on your performance.
Example of GPA Calculation (Semester 1):
| Course | Credit Hours | Grade | Grade Point (on 4.0 scale) | Credit Points |
|---|---|---|---|---|
| Calculus I | 4 | B | 3.0 | 4 * 3.0 = 12.0 |
| English 101 | 3 | A | 4.0 | 3 * 4.0 = 12.0 |
| Chemistry | 3 | B+ | 3.3 | 3 * 3.3 = 9.9 |
| Totals: | 10 | 33.9 |
Semester 1 GPA = Total Credit Points / Total Credit Hours = 33.9 / 10 = 3.39
What is CGPA? (The Big Picture)
CGPA, or Cumulative Grade Point Average, is the overall average of your grade points across every course you have taken throughout your entire academic program.
- Purpose: It represents your consistent academic performance over the long term. Universities and employers often use CGPA as a benchmark to assess a student’s overall capability and diligence.
- Calculation: It is calculated by taking the sum of all Credit Points earned in every semester and dividing it by the total number of credit hours attempted throughout your degree.
- Stability: While it changes each semester, the CGPA is less volatile than the GPA. A single bad semester will affect it, but its impact diminishes as you complete more courses.
Example of CGPA Calculation (After Semester 2):
Let’s add a second semester to our previous example.
Semester 2 Results:
| Course | Credit Hours | Grade | Grade Point | Credit Points |
|---|---|---|---|---|
| Physics | 4 | A | 4.0 | 4 * 4.0 = 16.0 |
| History | 3 | C+ | 2.3 | 3 * 2.3 = 6.9 |
| Programming | 3 | A- | 3.7 | 3 * 3.7 = 11.1 |
| Semester 2 Totals: | 10 | 34.0 | ||
| Semester 2 GPA | *34.0 / 10 = 3.40* |
Now, to find the overall CGPA:
- Total Credit Points (All Semesters): 33.9 (Sem 1) + 34.0 (Sem 2) = 67.9
- Total Credit Hours (All Semesters): 10 (Sem 1) + 10 (Sem 2) = 20
- CGPA = 67.9 / 20 = 3.395
This student’s Cumulative GPA after two semesters is 3.395.
Key Differences Summarized: GPA vs. CGPA
| Feature | GPA (Grade Point Average) | CGPA (Cumulative Grade Point Average) |
|---|---|---|
| Time Period | Short-term: For a single semester/term. | Long-term: For the entire duration of a program. |
| Purpose | Measures performance in a specific set of courses. | Measures overall, consistent academic performance. |
| Calculation Based On | Grades and credits from one semester only. | Grades and credits from all semesters completed so far. |
| Volatility | High. Can change dramatically each term. | Low. Changes gradually as more semesters are added. |
| Academic Use | Helps students track recent performance and identify issues in a specific term. | Used by institutions to determine academic standing, honors, eligibility for scholarships, and graduation. |
| Professional Use | Less commonly asked for by employers. | Frequently used by employers and postgraduate programs as a filtering criterion. |
Why Do Both Matter?
- A Strong Semester GPA is your tool for improving a low CGPA. If you had a difficult first year, consistently high GPAs in your following semesters will pull your cumulative average up.
- A Strong CGPA is your key to opportunities. It keeps doors open for competitive internships, graduate school applications, and employment offers that have minimum GPA requirements.
Frequently Asked Questions (FAQs)
Q: Do universities look at GPA or CGPA?
A: For admissions into postgraduate programs, universities almost always look at your CGPA as it reflects your overall capability. However, they may also review your transcript to see your GPA trend—an upward trend in your later semesters can be a positive sign, even if your CGPA isn’t perfect.
Q: Can I have a high GPA but a low CGPA (or vice versa)?
A:
- High GPA, Low CGPA: This is common. It means you are performing well now (high current GPA), but you had some poor semesters in the past that are dragging your overall average (CGPA) down.
- Low GPA, High CGPA: This is less common but possible. It means you had a bad semester (low current GPA), but your previous grades were so strong that your overall average (CGPA) is still high.
Q: How do I convert my CGPA to a percentage?
A: There is no single universal formula. The conversion method is specific to your university’s grading policy. Common methods include multiplying the CGPA by a standard factor (e.g., CGPA * 9.5 on a 10-point scale) or using a university-provided conversion table. Always use your institution’s official formula.
Conclusion: Two Sides of the Same Coin
In summary, GPA and CGPA are not rivals but two interconnected metrics that tell the full story of your academic journey. Your GPA is the chapter-by-chapter review, showing your immediate successes and challenges. Your CGPA is the review of the entire book, showcasing your overall consistency and long-term achievement.
By paying attention to both, you can strategically manage your academic performance, address problems early, and build a strong cumulative record that will serve you well in your future endeavors.
FAQs: GPA vs. CGPA
Q1: Which one is more important, my GPA or my CGPA?
A: Both are important, but they serve different purposes. Your CGPA is generally more important for your overall academic record, as it is the number used by employers and graduate schools to assess your long-term performance and consistency. However, a strong semester GPA is crucial for pulling up a low CGPA, earning Dean’s List honors for that term, and showing recent improvement.
Q2: If I have a low CGPA from my first year, can I still improve it?
A: Yes, absolutely. Your CGPA is a cumulative average, which means it is always possible to improve it with stronger performance in subsequent semesters. Because you take more courses as you progress, your later grades have a significant weight and can pull your overall average up. A consistent upward trend in your GPA is also viewed positively.
Q3: How is my CGPA calculated when I repeat a course I failed?
A: This depends entirely on your university’s specific policy. The two most common scenarios are:
- Grade Replacement: The new grade replaces the old one in the CGPA calculation. This is the best case for improving your average.
- Averaging Grades: Both the old failing grade and the new passing grade are factored into your CGPA.
Always check your institution’s academic regulations to understand their policy on repeated courses.
Q4: Do “W” (Withdrawal) or “I” (Incomplete) grades affect my GPA or CGPA?
A: No. Courses from which you withdraw or have an incomplete typically do not carry any grade points. Therefore, they are not included in the calculation of your GPA for that semester or your overall CGPA. However, they will remain on your official transcript.
Q5: When applying for jobs, should I put my GPA or CGPA on my resume?
A: The standard practice is to put your Cumulative GPA (CGPA) on your resume, as it represents your entire academic career. If your Major GPA (the GPA for courses only in your core subject) is significantly higher than your overall CGPA, you can list both (e.g., “CGPA: 3.4, Major GPA: 3.8”). If a semester GPA was exceptionally high and relevant, you could mention it in a cover letter to highlight a recent achievement.
Q6: My university uses a 10-point scale. What’s the difference between GPA and CGPA in this system?
A: The difference in concept remains exactly the same, regardless of the scale.
- Your GPA is your average on a 10-point scale for one semester.
- Your CGPA is your overall average on a 10-point scale for all semesters combined.
The calculation method (sum of (Grade Point × Credits) / total credits) is identical; only the grade point values change (e.g., an A might be a 9 or 10 instead of a 4.0).
Q7: If I transfer universities, does my CGPA from my old school carry over?
A: Typically, no. When you transfer, your new university will generally accept the credits you earned for passed courses. However, the grades from those courses usually do not get factored into your new CGPA at the new institution. You will start building a new CGPA from scratch, though your old transcript will still be part of your application file.
Q8: What’s the difference between CGPA and Overall Percentage?
A: CGPA is a weighted average based on a grade point system (e.g., A=4, B=3) and credit hours. An overall percentage is often a simple average of your percentage scores in each subject, without necessarily weighting them by credit hours. Converting between the two is not standardized, so you should use your university’s official conversion formula.
