SGPA to CGPA Conversion Calculator
To calculate the CGPA from SGPA, add the SGPA (0–10) of all semesters and divide by the total number of semesters (6–8). The result is your CGPA. As part of our study abroad calculator tools, we offer an easy-to-use online calculator below that helps you determine your CGPA instantly. All you need to do is enter the total number of semesters and the sum of SGPAs for all semesters, then click “CGPA.” You will get the exact CGPA percentage within a second.
What is SGPA?
SGPA stands for Semester Grade Point Average. SGPA is the weighted average of all the subject's grade points earned by a student in a semester. SGPA is a performance measure score awarded to the students at the end of all semesters. It is a 10-point scale system with 0.1 increments.
What is CGPA?
CGPA stands for Cumulative Grade Point Average. CGPA is the measurement of overall academic performance of the students throughout their education tenure in school or college. CGPA is the average grade points obtained by the students at the end of their academic program. It can be calculated by dividing the sum of all grade points obtained by the sum of credit points.
Difference Between SGPA and CGPA
| Criteria | SGPA (Semester Grade Point Average) | CGPA (Cumulative Grade Point Average) |
| Definition | SGPA is the average grade point of a specific semester, calculated based on the grades and credits of all subjects taken during that semester. | CGPA is the overall average grade point a student earns across all semesters of a course, calculated by combining the SGPA of each semester. |
| Purpose | Reflects short-term academic performance. | Reflects long-term academic achievements. |
| Time Period | Calculated for one semester only. | Calculated for an entire academic programme. |
| Scope | Evaluates academic performance of a particular semester. | Evaluates overall academic performance throughout the course. |
| Calculation | Average of grade points earned in all subjects in a semester, weighted by credit hours. | Weighted mean of SGPA from all semesters or years of study. |
| Usage | Track semester progress | Graduation score, higher education |
| Feedback | Provides semester-specific feedback | Provides cumulative feedback |
How to calculate SGPA?
As SGPA reflects on your performance over a period of time like a year or a semester, you must know how to calculate the SGPA from obtained marks. The SGPA is calculated based on the grades and credit points obtained. The steps to calculate SGPA are as follows,
Step 1: Note the individual credit points of all the subjects you appeared in that particular semester.
Step 2: Multiply the grade points obtained in each subject with their corresponding credit points.
Step 3: Now add all the resulting answers
Step 4: Add the credit point and find its total sum.
Step 5: Divide the sum of the grade points obtained by the sum of the credit points.
Step 6: The result obtained will be your SGPA.
For a better understanding, we have given you a sample SGPA calculation.
Let's say, the grades and the credit points of the 4 subjects in a semester are as follows.
| Subject | Grade point | Credit points |
| Subject 1 | 8 | 3 |
| Subject 2 | 9 | 4 |
| Subject 3 | 6 | 3 |
| Subject 4 | 7 | 4 |
SGPA to CGPA Calculator
SGPA to CGPA Calculator of One Semester
How to calculate CGPA from SGPA?
- Identify the SGPA for all the semesters. This will be the average score of all the subjects.
- Add the resulting SGPA for all the semesters.
- Then find the total number of semesters.
- To calculate CGPA from SGPA, divide the total SGPA by the number of sessions or semesters.
| CGPA = (Sum of all the SGPA) / (total number of semesters) |
The calculation can be explained with the help of a sample.
For instance, if the SGPA of a student in 4 semesters is,
Semester 1 - 8
Semester 2 - 7
Semester 3 - 7.9
Semester 4 - 6.9
The CGPA calculation will be as
CGPA = (Sum of all the SGPA) / (Total number of semesters)
= (8+7+7.9+6.9) / (4)
CGPA = 7.45
SGPA to Percentage Calculator
The Semester Grade Point Average of the student can be expressed in percentage. To convert SGPA to percentage, you have multiplied the obtained SGPA by 10 and then subtract the answer with 7.5.
| Percentage = (SGPA*10) - 7.5 |
SGPA to CGPA to Percentage
| CGPA | Equivalent Percentage (%) | CGPA | Equivalent Percentage (%) |
| 10 | 95 | 6.5 | 61.75 |
| 9.5 | 90.25 | 6 | 57 |
| 9 | 85.5 | 5.5 | 52.25 |
| 8.5 | 80.75 | 5 | 47.5 |
| 8 | 76 | 4.5 | 42.75 |
| 7.5 | 71.25 | 4 | 38 |
| 7 | 66.5 |
Common Errors to Avoid Using SGPA to CGPA Calculator
● Early Rounding Errors: Rounding numbers too early during the calculation process can lead to noticeable differences in the final CGPA. It is best to use exact values throughout the calculation and round off only at the final step.
● Overlooking Failed Subjects: When calculating SGPA in certain grading systems, failed subjects are also included. If these are ignored while calculating CGPA, it can produce an inflated or incorrect overall score.
● Using the Wrong Credit Scale: Different institutions follow different grading scales, such as a 4-point scale or a 10-point scale. Students must confirm their university’s credit system to ensure accurate CGPA calculations.
● Incorrect Credit Weightage: Using the wrong credit weightage for a semester can lead to an inaccurate CGPA. Students should always multiply their SGPA by the correct number of credits assigned to each semester.
● Not Verifying the Final Calculation: Always double-check your CGPA calculation. Even a small arithmetic mistake can affect the final result and lead to incorrect academic records.

Key Takeaways
Semester Grade Point Average (SGPA) and Cumulative Grade Point Average (CGPA) both indicate the weightage of marks secured by a student during their course program. These grades are used to secure admissions for their further higher studies.
You can easily convert SGPA to CGPA by adding all the SGPAs and dividing them by the total number of semesters.
FAQ
1. What is the CGPA of 7.5 SGPA?
CGPA for 7.5 SGPA will be 7.5. This is because, if you are calculating the CGPA for one semester then the SGPA will be your CGPA.
2. How to calculate CGPA?
The CGPA is the Cumulative grade points obtained by the students throughout their education tenure. To calculate the CGPA, you can take the weighted average of the SGPAs obtained during the particular course duration.
3. How is CGPA calculated from SGPA?
CGPA is calculated from SGPA using the following formula.
CGPA = (Sum of all the SGPA) / (total number of semesters)
4. Is SGPA and CGPA the same?
No, SGPA and CGPA are different. SGPA is the score obtained by the student in a semester, whereas CGPA is the cumulative score secured by the students during their entire education program.
5. What is the difference between SGPA and CGPA in college?
CGPA is the overall grade point that gives the student performance throughout their course. SGPA is the grade point average that is used to calculate the student's performance for a particular session or semester. The weighted average of SGPA for all the semesters gives the CGPA.
6. Which is more important, SGPA or CGPA?
CGPA is considered to be more important than SGPA because most universities and institutions use CGPA for their admission process. However, as SGPA is an integral part of the CGPA, a good semester score is necessary for overall performance.
