What is SGPA? Let’s Break It Down Before You Panic
SGPA stands for Semester Grade Point Average. It shows how well you performed in one single semester. It is not your full college score. It is just the result of that specific term.
Every subject in a semester has credits. Every grade you get has a grade point. SGPA is calculated by combining both. Subjects with more credits affect your SGPA more. That is why core subjects matter more than small labs.
SGPA is always calculated on a 10-point scale in most Indian universities. A higher SGPA means better academic performance for that semester.
SGPA changes every semester. One bad semester can lower it. One good semester can fix it. That is why students track SGPA closely after every result.
How to Calculate SGPA with Example Calculation?
SGPA is calculated in almost the same way across countries and universities. This is why it matters for Indian students who plan to study abroad. Even when universities use different grading systems, the base logic of SGPA stays universal.
To calculate SGPA, you need two things for one semester only.
Your subject credits and your grade points.
Step 1: List your subjects and their credits
Each subject has a fixed credit value. Core subjects usually have more credits than labs or electives. These credits show how important the subject is in your semester.
Step 2: Note your grade points
Every grade is converted into a number called a grade point. Most systems follow a 10-point scale.
For example:
A or A+ usually means 9 or 10
B usually means 8
C usually means 7
Even if the letter grades differ abroad, universities convert them into grade points internally.
Step 3: Multiply grade points by credits
For each subject, multiply the grade point by its credit value. This shows the weight of that subject in your SGPA.
Step 4: Add all the weighted scores
Add the results of all subjects together.
Step 5: Add total credits
Now add the credits of all subjects in that semester.
Step 6: Divide to get SGPA
Divide the total weighted score by the total credits.
SGPA = Total (Grade Points × Credits) ÷ Total Credits
Example calculation
Imagine an Indian student planning to apply abroad after this semester.
- Subject 1: 4 credits, grade point 9
- Subject 2: 3 credits, grade point 8
- Subject 3: 2 credits, grade point 10
Weighted score: (4 × 9) + (3 × 8) + (2 × 10) = 36 + 24 + 20 = 80
Total credits: 4 + 3 + 2 = 9
SGPA = 80 ÷ 9 = 8.88

How to Convert SGPA to Percentage & Back Without Losing Yourself?
SGPA and percentage are just two different ways of showing the same performance. Most Indian universities give an SGPA. Many foreign universities ask for a percentage. So conversion becomes necessary when you apply abroad.
There is no single global formula. Each university or education board may follow a slightly different rule. Still, most international applications accept standard conversion methods.
Converting SGPA to Percentage Formula
The most commonly used formula is: Percentage = (SGPA − 0.75) × 10
This formula is widely accepted for Indian students during international applications when no official conversion is provided.
Example:
If your SGPA is 8.5
Percentage = (8.5 − 0.75) × 10
Percentage = 77.5%
This gives universities abroad a clear idea of your academic level.
Converting Percentage to SGPA
Sometimes students get percentage marks and want to estimate their SGPA.
A basic reverse method is: SGPA = (Percentage ÷ 10) + 0.75
Example:
If your percentage is 80%
SGPA = (80 ÷ 10) + 0.75
SGPA = 8.75
This is an estimate, not an official score.
Note: Always check your university’s official grading policy first. If your transcript includes a conversion formula, use only that. If not, universities abroad usually convert scores themselves during evaluation. Never round off aggressively. Use exact values.
How to Calculate CGPA from SGPA in Easy Steps?
CGPA shows your overall academic performance across multiple semesters. While SGPA is for one semester, CGPA combines all semesters together. This is important for Indian students applying to universities abroad because most international universities ask for CGPA, not just SGPA. To calculate CGPA, you need the SGPA of each completed semester and the total credits of those semesters.
Step 1: List the SGPA of all semesters
Write down the SGPA for every semester you have completed so far. Do not skip any semester, even if the score is low.
Step 2: Note the total credits for each semester
Each semester has a fixed number of credits. These credits decide how much weight that semester has in your CGPA.
Step 3: Multiply SGPA by semester credits
For every semester, multiply the SGPA by the total credits of that semester. This gives the weighted score for that semester.
Step 4: Add all weighted scores
Add the results of all semesters together.
Step 5: Add total credits of all semesters
Now add the credits from all semesters.
Step 6: Divide to get CGPA
Divide the total weighted score by the total credits.
CGPA = Total (SGPA × Semester Credits) ÷ Total Credits
Example:
Assume a student has completed three semesters:
- Semester 1: SGPA 8.0, credits 20
- Semester 2: SGPA 8.5, credits 22
- Semester 3: SGPA 9.0, credits 24
Weighted score:
(8.0 × 20) + (8.5 × 22) + (9.0 × 24)
160 + 187 + 216 = 563
Total credits: 20 + 22 + 24 = 66
CGPA = 563 ÷ 66 = 8.53

SGPA Grading Scale & Sample Conversion Table That Makes Sense
Most universities use a 10-point grading scale. The letter grades may change, but the meaning stays similar across systems.
Common SGPA grading scale
This is a widely used reference scale for Indian students applying abroad:
- 9.0 to 10.0 – Outstanding performance
- 8.0 to 8.9 – Very good performance
- 7.0 to 7.9 – Good performance
- 6.0 to 6.9 – Average performance
- Below 6.0 – Needs improvement
Sample SGPA to percentage conversion table
International universities do not judge only by the label. They focus on where your SGPA falls on this scale.
| SGPA | Approximate Percentage |
| 10.0 | 92 to 95% |
| 9.0 | 82 to 85% |
| 8.0 | 72 to 75% |
| 7.0 | 62 to 65% |
| 6.0 | 52 to 55% |
Does SGPA Affect University Applications and Scholarships? Let’s Spill the Tea
Yes, SGPA does affect university applications and scholarships, especially for students applying abroad. Universities convert SGPA into CGPA or percentage to check if you meet academic eligibility criteria.
Many merit-based scholarships also use these converted scores to set cut-offs. A strong SGPA supports your academic profile, while a low SGPA may need justification through other factors like test scores or work experience. SGPA alone does not decide admission or funding, but it forms the academic base of your application.

Important Things to Consider While Calculating SGPA
For students planning to study abroad, accuracy matters because these numbers are later converted and reviewed by universities. Here are some important things to consider while calculating SGPA:
- Always use the official credit value given on your transcript, not what you assume the subject carries.
- Do not mix grades from different semesters while calculating SGPA. It is semester-specific.
- Follow your university’s exact grading scale, especially if plus or minus grades exist.
- Avoid rounding off early. Round only the final SGPA, not intermediate values.
- If a subject is repeated or re-evaluated, use the latest approved grade only.
- Double-check totals before dividing. One missed credit can change the result.
FAQs
SGPA is calculated by multiplying grade points by subject credits, adding all the results, and dividing by the total credits of the semester. It reflects performance for one semester only. Most universities use a 10-point scale for this calculation.
To estimate SGPA from a percentage, many students use the reverse formula (Percentage ÷ 10) + 0.75. Based on this, 70% is roughly equal to 7.75 SGPA. This is an estimate and not an official score.
A commonly used conversion formula is (SGPA − 0.75) × 10. Using this, 7.5 SGPA is approximately equal to 67.5%. This value is used when no official conversion is provided on the transcript.
Yes, SGPA can be calculated manually using subject credits and grade points. You do not need any tools if your grading scale is clear. Manual calculation is often more accurate for application purposes.
No, 70% is usually higher than a 2.0 GPA. In most international grading systems, 70% is closer to a 3.0 GPA on a 4.0 scale. Final GPA equivalence is decided by the university during evaluation.
