What is CGPA? The short answer
CGPA stands for cumulative grade point average. It’s the average of your grade points across every semester you’ve completed so far, weighted by credit hours. Your GPA (or SGPA, semester grade point average) usually covers one semester. Your CGPA covers all of them together.
Your scale depends on where you study. US colleges usually use a 4.0 scale, and so does the University of the Punjab in Pakistan. India’s CBSE board and IIT Mandi use a 10-point scale, and the National University of Singapore uses 5.0. That’s why a CGPA only makes sense next to its scale, such as “3.40 out of 4.00” or “8.2 out of 10.”
CGPA vs GPA vs SGPA
| Term | What it covers | Also called |
|---|---|---|
| GPA or SGPA | One semester or term | Term GPA, semester GPA |
| CGPA | Every semester so far, combined | Cumulative GPA, overall GPA |
The math is the same for both. The only difference is how many semesters you include. What is a GPA? covers the basics of grade points and scales.
How to calculate CGPA
CGPA = total (grade points × credit hours) ÷ total credit hours, across all semesters
The University of the Punjab’s rules for its MS, MPhil and PhD programs describe exactly this method. Multiply each course’s grade points by its credit hours, add the results, and divide by the total credit hours. For a semester GPA you use one semester’s courses. For CGPA you use every course in the program so far. Our step-by-step semester GPA guide walks through the method in detail.
Example 1: from course grades (4.0 scale, common US values)
| Course | Credit hours | Grade | Grade points × credit hours |
|---|---|---|---|
| Calculus | 3 | A (4.0) | 12.0 |
| Physics | 3 | B+ (3.3) | 9.9 |
| Lab | 2 | C (2.0) | 4.0 |
Example 2: from semester GPAs
If you already know each semester’s GPA, multiply it by that semester’s credit hours first:
- Semester 1: GPA 3.00 over 18 credit hours = 54.0
- Semester 2: GPA 3.50 over 15 credit hours = 52.5
- CGPA: (54.0 + 52.5) ÷ (18 + 15) = 106.5 ÷ 33 = 3.227…, which rounds to 3.23
A plain average of 3.00 and 3.50 gives 3.25, which is slightly too high, because the weaker semester had more credit hours. Only when every semester has the same credit hours does a plain average give the right CGPA. What are credit hours? and what are quality points? explain the two parts of the formula.
CGPA scales in different countries
| Scale | Top grade | Example |
|---|---|---|
| 4.0 | A = 4.00 | University of the Punjab (MS/MPhil/PhD rules): 85% and above is an A, worth 4.00 |
| 5.0 | A or A+ = 5.0 | National University of Singapore: A+ and A are both 5.0, A− is 4.5 |
| 10-point | 10 | India’s CBSE (Classes IX–X) and IIT Mandi |
Grade boundaries differ too. At the University of the Punjab, 85% or more is an A (4.00) and 58–60% is a C (2.00). On many US grading scales, a 90% is an A−. So you can’t compare two CGPAs from different universities without their grading tables. The GPA scale chart shows how common US scales work.
Converting CGPA to percentage
There’s no universal formula. Each board or university sets its own rule, and some don’t allow a conversion at all:
- CBSE (India, Class IX–X grading under its 2010 circular): an “indicative” percentage is 9.5 × CGPA. So an 8.2 CGPA is about 77.9%.
- IIT Mandi: its letter says its grade points “are not convertible into percentage,” and gives 10 × CGPA only as a notional figure. So an 8.2 CGPA would be a notional 82%.
So the same 8.2 gives about 78% under one rule and 82% under another. If an application asks for a percentage, use the formula on your own university’s transcript or official letter. If there isn’t one, ask the registrar or the institution you’re applying to, rather than using a general online converter.
Converting CGPA to a US 4.0 GPA
Some students divide a 10-point CGPA by 10 and multiply by 4, so 8.0 becomes 3.2. That’s only a rough estimate. It ignores how each university sets its grade boundaries. Many US universities and credential evaluators recalculate your grades course by course with their own rules. For an application, follow the receiving school’s instructions instead of converting it yourself.
What is a good CGPA?
It depends on the scale and your goal. On a 4.0 scale, a 3.0 is a B average and a 3.5 or above is strong. Programs set their own minimums. The University of the Punjab, for example, requires MS and MPhil students to keep a CGPA of at least 2.50, and PhD students at least 3.00. For US benchmarks, see what is a good GPA?. Many colleges also give term honors, such as the dean’s list, for a high semester GPA.
How to raise your CGPA
Because CGPA is weighted by credit hours, two things matter most:
- Classes with more credit hours move it more. An A in a 4-credit course helps more than an A in a 1-credit course.
- It gets harder to move over time. The more credit hours you’ve completed, the less one good semester changes the total.
If your CGPA is on a 4.0 scale, the cumulative GPA calculator shows how a new semester changes it. It doesn’t handle 10-point scales. How to raise your GPA has worked examples.
Frequently asked questions
What is the full form of CGPA?
CGPA stands for cumulative grade point average: the credit-weighted average of your grade points across all completed semesters.
Is CGPA the same as GPA?
Not quite. GPA (or SGPA) usually covers one semester, while CGPA covers every semester so far. In the US, people often say “GPA” when they mean the cumulative one.
How do I calculate CGPA from SGPA?
Multiply each semester’s SGPA by that semester’s credit hours, add the results, and divide by the total credit hours. Only average the SGPAs directly if every semester has the same credit hours.
Can I multiply my CGPA by 9.5 to get a percentage?
Only if your board or university says so. The 9.5 multiplier comes from a CBSE circular for its own grading. Other institutions use different rules, and some, like IIT Mandi, say their grade points can’t be converted.
Is a 3.0 CGPA good?
On a 4.0 scale, a 3.0 is a B average. It meets many minimums, but some programs and scholarships ask for more. On a 10-point scale, 3.0 would be very low. On NUS’s 5.0 scale, it equals a B−. Always check the scale.
