The SGPA Calculator is a smart, interactive tool that helps students calculate their Semester Grade Point Average quickly and accurately. Unlike traditional calculators, this one is fully editable — you can customize grade values, change subject credits, and even modify grade-point mappings based on your university’s unique grading system.
Whether you’re a college student, an engineering undergrad, or a management student, understanding your SGPA helps you measure your academic progress semester by semester. This calculator makes that process effortless, accurate, and transparent — no more manual errors or confusing formulas.
What Is SGPA?
SGPA stands for Semester Grade Point Average. It represents a student’s academic performance for one semester, based on the grades earned in each subject and the corresponding credit weight of those subjects. Each grade has a numerical value (called a grade point), which reflects the student’s performance in that subject.
The SGPA is essentially the weighted average of your grade points. A higher SGPA means a better semester result, while consistent SGPAs contribute to a strong overall CGPA (Cumulative Grade Point Average).
SGPA = (Σ Credit × Grade Point) ÷ Σ Credits
In this formula:
- Credit refers to the weight or importance of each subject in your semester.
- Grade Point is the numeric value assigned to the grade you received.
- Σ (Sigma) means the sum of all subjects in that semester.
How the SGPA Calculator Works
This editable SGPA calculator allows you to enter your subjects, input the grades, and assign credits. What sets it apart is the ability to edit grade points. You are not limited to any fixed 10-point or 4-point scale — you can create your own grade mapping according to your institution’s evaluation system.
Here’s how it works:
- Enter the number of subjects in your semester.
- Provide the subject name, grade obtained, and credit value.
- Edit grade point values (for example, set A+ = 9.3 instead of 9.0 if your college uses that system).
- Click the Calculate SGPA button.
- The calculator instantly displays your SGPA and equivalent percentage.
The system automatically multiplies each subject’s grade point by its credit value and divides the total by the total number of credits. Within seconds, you get an accurate SGPA without needing any manual calculations.
SGPA Formula Explained with Example
Let’s go through a practical example to understand how the formula works. Suppose a student has the following grades and credits:
| Subject | Credits | Grade | Grade Point | Credit × Grade Point |
|---|---|---|---|---|
| Mathematics | 4 | A+ | 9.0 | 36.0 |
| Physics | 3 | A | 8.0 | 24.0 |
| Chemistry | 3 | B+ | 7.0 | 21.0 |
| English | 2 | O | 10.0 | 20.0 |
Total Credits = 4 + 3 + 3 + 2 = 12
Total Credit Points = 36 + 24 + 21 + 20 = 101
SGPA = 101 ÷ 12 = 8.42
The student’s SGPA is 8.42. If you multiply this by 9.5, you get approximately 80%, which represents their semester percentage.
Why Use an Editable SGPA Calculator?
Unlike static calculators that lock you into a single grading scale, this tool empowers you to input custom grade points. Many universities and autonomous institutions modify their grading scales slightly — some consider A+ as 9.5, others use 9.0. By editing these values, you can calculate SGPA that truly reflects your institution’s criteria.
- Customizable: Modify grade values anytime.
- Accurate: Get precise results without human error.
- Universal: Works with any credit system globally.
- Downloadable: Export your SGPA report as a PDF for record keeping.
- Responsive: Optimized for both mobile and desktop use.
Difference Between SGPA, CGPA, and GPA
Students often confuse SGPA, CGPA, and GPA, but each serves a different purpose. Here’s a simple breakdown:
| Metric | Description | Calculation | Usage |
|---|---|---|---|
| SGPA | Semester Grade Point Average | Average of grade points for one semester | Used for internal evaluation |
| CGPA | Cumulative Grade Point Average | Average of SGPAs across semesters | Used for overall academic record |
| GPA | Grade Point Average (Global) | Used in 4-point scale systems | Common in US/Canada universities |
If you want to know your overall academic performance, you can use our CGPA Calculator — it takes your SGPAs from multiple semesters and computes your cumulative grade point average automatically.
Convert SGPA to Percentage
Most universities convert SGPA to percentage using a simple formula:
Percentage = SGPA × 9.5
This conversion is widely used in the 10-point system, but since the SGPA calculator allows editable grade values, you can modify the formula if your university uses a different conversion factor. For instance, some engineering institutions use Percentage = (SGPA × 10) - 5.
The calculator displays both SGPA and an approximate percentage instantly, giving you a clear idea of your performance in terms of marks.
Example: Customizing Grades in SGPA Calculator
Suppose your university defines the following custom scale:
| Grade | Description | Grade Point |
|---|---|---|
| O | Outstanding | 10 |
| A+ | Excellent | 9.3 |
| A | Very Good | 8.4 |
| B+ | Good | 7.5 |
| B | Average | 6.5 |
You can directly edit these values inside the calculator’s “Edit Grade Points” section. The SGPA formula instantly adapts to your changes, ensuring your result aligns with your institution’s grading structure.
