SGPA means Semester Grade Point Average. It is the average grade point for one semester. Students usually calculate it after they know subject grades, grade points, or marks for a semester. If one subject has more credits, it affects SGPA more than a low-credit subject.
SGPA = Sum of (Subject Credits x Grade Point) / Sum of Subject Credits
For example, if a 4-credit subject has 9 grade points, it contributes 36 weighted points. A 2-credit subject with the same grade point contributes 18 weighted points. This is why SGPA should not be calculated by adding all grade points and dividing by the number of subjects.
CGPA means Cumulative Grade Point Average. It combines more than one semester into one average. Students use it to understand their overall performance across semesters. If semester credits are available, a credit-weighted CGPA is better. If credits are not available, use the simple average.
Weighted CGPA = Sum of (Semester SGPA x Semester Credits) / Sum of Semester Credits
A weighted CGPA gives more importance to semesters with more credits. A simple average treats every semester equally. Both methods are useful, but they can give different results, so choose the method that matches the data you have.
A grade point is the number value of a grade. For example, A may be 9, B+ may be 8, and F may be 0. Many colleges use similar scales, but the exact mapping can change. That is why this calculator lets you edit the grade mapping.
If you know only the letter grade, use the subject grades mode. If you already know the grade point, use the grade points mode. If you are not sure, start with the data that is easiest to trust, then adjust the grade mapping only when needed.
Marks cannot become SGPA directly unless you first apply a marks-to-grade or marks-to-point scale. Example: 90-100 may be 10 points, 80-89 may be 9 points, and so on. Use the marks mode only after checking the scale used in your course.
The calculator first converts marks into a percentage. For example, 45 out of 50 is 90%. It then checks which range contains 90 and uses the grade point for that range. After that, SGPA is calculated with credits.
| Point | SGPA | CGPA |
|---|---|---|
| Meaning | Average grade point for one semester. | Average grade point across multiple semesters. |
| Used for | Checking one semester result. | Checking overall course progress. |
| Input needed | Subject credits and grade points, grades, or marks. | Semester SGPAs and optional semester credits. |
| Best method | Credit-weighted subject calculation. | Credit-weighted semester calculation when credits are known. |
| What changes it | Current semester subjects and grades. | All included semesters, so it changes slowly. |
There is no single CGPA to percentage formula for every college. Some use CGPA x 9.5, some use CGPA x 10, and some use another rule. Use the percentage converter only with the formula that fits your course.
If you do not know the exact formula, the percentage result should be treated as an estimate. The CGPA or SGPA value itself is still useful for checking progress, comparing semesters, and planning target scores.
Use Subject grades when your data is in letters such as O, A+, A, B+, B, C, P or F. Use Subject grade points when your data is already numeric, such as 10, 9, 8 or 7. Use Subject marks when you know marks obtained and maximum marks. Use Semester SGPAs when you already know semester results and want CGPA.
The tool is designed so you do not need to force your data into one fixed format. Pick the mode that matches what you have right now. If you later get better data, go back, change the mode, and calculate again.
Credits are important because they decide how much a subject counts. Suppose Engineering Mathematics has 4 credits and a grade point of 9. Its weighted value is 36. Suppose English has 2 credits and a grade point of 9. Its weighted value is 18. Both subjects have the same grade point, but Mathematics affects SGPA more because it has more credits.
This is the main reason credit-weighted calculation feels more accurate than a simple average. The calculator shows total credits and weighted grade points so you can see how the final number was built.
The target planner helps you understand what average SGPA is needed in the remaining semesters. It is useful when you have a goal such as reaching 8.0, 8.5, or 9.0 CGPA. If the required SGPA is above 10, the tool marks it as mathematically impossible because most common grading systems do not go above 10.
If the required SGPA is realistic, use it as a planning number. It does not guarantee a final result, but it gives you a clear target for upcoming semesters.
This CGPA and SGPA calculator works in your browser. Subject names, credits, marks, grades, semester SGPAs, grade rules, target CGPA inputs, and percentage formula settings may be saved in localStorage so the form can stay filled when you return from the same browser.
The tool does not require an account or a database, and the calculation data is not uploaded by this tool. If you are using a shared device, clear saved data after use. If you clear browser data, use private browsing, or open another browser, the saved rows may not be available.
Yes. Open the grade rules and set the points used by your college.
Weighted CGPA gives more weight to semesters with more credits. Simple average treats every semester the same.
Only after choosing the marks-to-grade or marks-to-point rule that fits your course. The default scale is just a starting point.
Choose the option that matches the data in front of you. Use marks for raw marks, grades for letters, grade points for numbers, and semester SGPAs for CGPA.
Choose Subject grades, or choose Subject grade points and switch the dropdown to Grades. Then check the grade mapping below it.
Yes. Use Subject marks if you know marks obtained and maximum marks. The result depends on the marks scale you set.
Yes. Use Back to edit. Your rows stay saved while you move between steps.
Download it after you verify the inputs, formula, and final result. The PDF uses only the report details, not the whole page.
This calculator is for checking, planning, and making a personal report from the data you enter. Colleges can use different grading and percentage rules, so match the settings with the rule followed in your course.
