How SGPA is calculated
SGPA = Σ (Credits × Grade point) ÷ Σ Credits
Each subject's grade point is multiplied by its credits, the results are added up and divided by the total credits. Subjects with more credits count more.
| Subject | Credits | Grade | Points | Credits × points |
|---|---|---|---|---|
| Mathematics | 4 | A+ | 9 | 36 |
| Physics | 4 | A | 8 | 32 |
| Programming | 3 | O | 10 | 30 |
| English | 3 | B+ | 7 | 21 |
| Lab | 2 | A | 8 | 16 |
| Total | 16 | 135 |
SGPA = 135 ÷ 16 = 8.44.
How CGPA is calculated
CGPA = Σ (Semester credits × SGPA) ÷ Σ Semester credits
Example: 8.2 SGPA in a 22-credit semester and 8.6 in another 22-credit semester give CGPA = (22 × 8.2 + 22 × 8.6) ÷ 44 = 8.4. If the semesters had different credits, the larger one would weigh more — which is why a simple average of SGPAs can be slightly wrong.
10-point grading scale (UGC CBCS)
| Letter grade | Grade point | Meaning |
|---|---|---|
| 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 |
4-point scale
US universities use a 4.0 scale: A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D = 1.0, F = 0. Indian students applying abroad often need their GPA on this scale; many universities ask for a WES or university-issued evaluation rather than a self-calculated conversion.
SGPA, CGPA and percentage at a glance
| Measure | Covers | Typical use |
|---|---|---|
| SGPA | One semester | Semester result, scholarships that look at the latest term |
| CGPA | All semesters so far | Degree classification, placements, higher studies |
| Percentage | Converted from CGPA by a formula | Government jobs and forms that ask for marks in % |
Most Indian universities award a first class with distinction at a CGPA of about 7.5 and above, and a first class at 6.5 and above — but the cut-offs vary, so check your university's ordinance.
How to raise your CGPA
- Focus on high-credit subjects — a 4-credit subject moves your SGPA twice as much as a 2-credit one.
- Don't neglect labs and projects — they are easier to score in and carry credits too.
- Clear backlogs early — a failed (F) subject pulls the CGPA down until it is cleared.
- Plan ahead with this calculator — enter the grades you expect to see what CGPA you can reach by the end of the year.
Frequently asked questions
How do I calculate SGPA?
Multiply each subject's credits by its grade point, add them up, and divide by the total credits. Enter your subjects in the calculator to get it instantly.
How is CGPA different from SGPA?
SGPA covers one semester; CGPA covers all semesters so far, with each semester weighted by its credits.
Can I average my SGPAs to get CGPA?
Only if every semester has the same credits. Otherwise weight each SGPA by its semester's credits, as this calculator does.
How do I convert CGPA to percentage?
It depends on your university. Use our CGPA to Percentage calculator, which includes CBSE and common university formulas and a custom option.
What is a good CGPA?
On a 10-point scale, 8 and above is generally considered very good, 7–8 good, and 6–7 average. Many companies set a cut-off of 6 or 6.5 CGPA for campus placements.
