Done calculating your semester grade? Combine all your semesters into a final CGPA.
Results are out. Your marksheet is in front of you. And now your college is asking for your SGPA for the semester.
Most students take out a notebook and do manual calculations, which takes a lot of time. On top of that, manual calculation can sometimes give you the wrong number — one small addition mistake and the whole result goes off.
This SGPA calculator solves that in seconds, with no errors. Enter your subject credits and either letter grades or raw marks, and your semester grade point average is ready instantly.
What is SGPA?
SGPA — Semester Grade Point Average — is the weighted average of grade points you earn across all subjects in one semester, based on how many credit hours each subject carries.
In simple terms, it is a number that reflects your academic performance for a single semester, usually six months.
SGPA is not just a number your college asks for. It decides your scholarship eligibility at many institutions, determines whether you qualify for hostel fee waivers, flags backlogs early before they pile up, and is the first thing a placement recruiter looks at when your resume lands on their desk. Tracking it every semester — not just at the end of your degree — gives you time to fix things while you still can.
How to Calculate SGPA (Semester Grade Point Average)
To calculate SGPA, divide the sum of (Credits × Grade Points) for all subjects by the total number of credits in the semester.
The formula is not complicated — but with six or seven subjects, different credits, and multiple grade values, it is easy to make an error by hand.
This is the standard method to convert your Credit points to SGPA.
Let's understand it with an example
Say you have three subjects this semester:
| Subject | Credits | Grade | Grade Points |
|---|---|---|---|
| Mathematics | 4 | A | 8 |
| Physics | 3 | A+ | 9 |
| English | 2 | B+ | 7 |
Step 1 — Multiply each subject's credits by its grade points:
- Mathematics: 4 × 8 = 32
- Physics: 3 × 9 = 27
- English: 2 × 7 = 14
Step 2 — Add all the values: 32 + 27 + 14 = 73
Step 3 — Divide by total credits: 73 ÷ 9 = 8.11
Your SGPA for this semester: 8.11
However, the letter grading values are not identical across universities.
How to Calculate SGPA from Marks
Some colleges don't issue letter grades at all. Your marksheet shows numbers — 78 in Maths, 65 in Physics, 54 in Chemistry. No A, no B+, nothing. Just raw scores.
To calculate SGPA from marks, you first convert each subject's marks into a grade point, then run the standard SGPA formula on those grade points.
So, how do you find your grade points? You need to convert your marks into a percentage first.
If your exam is out of 100, your marks are already your percentage. But if your paper is out of 75 or 50, divide your marks by the total and multiply by 100.
For example, if you scored 56 out of 75, your percentage is (56 ÷ 75) × 100 = 74.6%.
Not sure how to do this for all your subjects at once? Use our Marks Percentage Calculator — it converts your raw marks to a clean percentage in seconds, so you can move straight to the SGPA calculation.
Once you have the percentage, match it to the UGC standard scale. Most central and state universities in India follow the UGC's Choice Based Credit System (CBCS), which uses a standard 10-point scale:
| Grade | Description | Grade Points | Marks Range |
|---|---|---|---|
| O | Outstanding | 10 | 90 – 100 |
| A+ | Excellent | 9 | 80 – 89 |
| A | Very Good | 8 | 70 – 79 |
| B+ | Good | 7 | 60 – 69 |
| B | Above Average | 6 | 55 – 59 |
| C | Average | 5 | 50 – 54 |
| P | Pass | 4 | 45 – 49 |
| F / Ab | Fail / Absent | 0 | Below 45 |
Note: Many universities follow a different letter grade system, so always confirm with your university's official grading guidelines. If you are a VTU student, we have a dedicated VTU SGPA Calculator that loads VTU's grading scale automatically — no manual setup needed.
How to Calculate the SGPA of a Semester
Let's say you have 6 subjects in a semester, and your college has given you raw marks out of 100:
| Subject | Marks (out of 100) | Credits | Percentage | Grade Points | Credit Points (Credits × GP) |
|---|---|---|---|---|---|
| Maths | 78 | 4 | 78% | 8 | 32 |
| Physics | 65 | 3 | 65% | 7 | 21 |
| Chemistry | 54 | 3 | 54% | 6 | 18 |
| English | 91 | 2 | 91% | 10 | 20 |
| Programming | 82 | 4 | 82% | 9 | 36 |
| Workshop | 47 | 2 | 47% | 5 | 10 |
| Total | — | 18 | — | — | 137 |
Add all the credit points: 32 + 21 + 18 + 20 + 36 + 10 = 137
Add all the credits: 4 + 3 + 3 + 2 + 4 + 2 = 18
SGPA of this semester = 137 ÷ 18 = 7.61
One thing worth noticing here. English scored the highest marks — 91 out of 100, a perfect 10 grade points. But because it only carries 2 credits, it contributes just 20 credit points to the total. Programming scored 82, one grade lower, but carries 4 credits — so it contributes 36 credit points. Nearly double the impact despite a lower grade. This is exactly why SGPA is a weighted average and not a simple one. High-credit subjects move your SGPA far more than low-credit ones, regardless of how well you score in them.
Don't want to do this manually? Switch to Marks Mode in our Marks to SGPA calculator, enter your raw scores and credits for each subject, and it handles everything automatically.
How to Calculate the Total SGPA of All Semesters
Once you have the SGPA for each semester, combining them into one overall figure is a separate calculation — and that figure is called your CGPA. You cannot simply add your SGPA and divide by the number of semesters, because each semester may carry different total credits. The right method weights each semester's SGPA by its credit load.
Use our SGPA to CGPA calculator to do this — enter the SGPA and total credits for each semester, and your overall CGPA is ready instantly.
Frequently Asked Questions (FAQs)
What is a good SGPA in India?
8.0 and above is where you are sitting comfortably. For placements, 7.5 is the number most companies work with. Drop 7.0 and options narrow below — but they don't disappear completely.
What is the difference between SGPA and CGPA?
SGPA is your score for one semester. CGPA is the average of all your semesters put together. Got 8.2 in Sem 1 and 7.8 in Sem 2? Your CGPA is 8.0.
Is a 7.5 SGPA good enough for placements?
For most companies, yes. TCS, Infosys, and Wipro start around 6.0 to 7.0. Deloitte and Accenture usually want 7.5. Product companies and core roles push it to 8.0 and above.
How do I convert SGPA to a percentage?
Depends on your university. UGC formula is (SGPA × 10) − 7.5. VTU and SRM use SGPA × 10. AKTU uses (CGPA − 0.75) × 10. For a quick and accurate conversion, use our SGPA to Percentage Calculator. Always check your university's official policy before putting a converted number on any official form.
What if my college only gives raw marks, not letter grades?
Switch to Marks Mode. Enter your marks and credits, and the calculator converts everything — marks to grade points to SGPA — in one go. For universities with different cutoffs, use Custom Points instead and enter the grade points directly from your official grading chart.
Conclusion
Your SGPA is not just a number your college tracks — it is something worth tracking yourself. A weak semester at the start of your degree is recoverable, but only if you catch it early. A strong SGPA through the first two years gives you breathing room when the final semesters get harder.
Use this calculator at the end of every semester, not just when you need the number for a form. Knowing where you stand is always better than guessing.
