SGPA Calculator
SGPA (Semester Grade Point Average) measures your performance in a single semester. It’s calculated from the grades and credit hours of all courses taken that semester.
In India, grades are often on a 10-point scale (e.g. O=10, A=9, B=8, etc.), and each subject has a credit value reflecting its weight.
SGPA Formula
SGPA = (Σ (Credit Points × Grade Points)) ÷ (Σ Credit Points)
Here, Credit Points are the credit hours of each course, and Grade Points are the numeric value of the letter grade for that course.
Explanation of Formula Terms
Credit
Weight of the subject
Grade Point
Numeric value of grade
Total Credits
Sum of all subject credits.
How to Calculate SGPA
List Subjects
Note each subject’s credit hours and grade point (from your grade).
Multiply
For each subject, multiply its credit hours by its grade point.
Sum
Add up all the products to get total weighted grade points.
Divide
Divide the total weighted grade points by the total credits.

CGPA Calculator
CGPA (Cumulative Grade Point Average) measures your overall academic performance across multiple semesters. It’s calculated by summing up the SGPA of all semesters and dividing by the total number of semesters.
In India, grades are often on a 10-point scale (e.g. O=10, A=9, B=8, etc.), and each subject has a credit value reflecting its credit value reflecting its weight.
CGPA Formula
CGPA = (Σ (Credit Points × Grade Points)) ÷ (Σ Credit Points)
Some universities simply average all semester SGPAs when each semester has equal credits.
How to Calculate CGPA
Get SGPAs
Use the SGPA formula (or calculator) to find the SGPA for each semester of study.
Multiply by Credits
Multiply each semester’s SGPA by the total credit hours of that semester.
Sum Up
Add all the results from step 2 to get total weighted points, and also sum all semester credits.
Divide
Divide the total weighted points by total credits. The result is your CGPA.

SGPA to Percentage Calculator
This tool transforms a Semester GPA into an approximate percentage score. Indian universities and boards often require percentages for things like admissions, and a common conversion is needed.
SGPA to Percentage Formula
Percentage = (SGPA – 0.75) × 10
A widely used conversion. But different institutions may use slightly different formulas
Note
Different institutions may use slightly different formulas (some use SGPA×10, others (SGPA−0.75)×10), but both yield similar results. Always check your university’s official conversion if precision is critical
How to Calculate SGPA to Percentage
Compute SGPA
First find your SGPA.
Apply Formula
Multiply the SGPA by 10, then subtract 7.5 (which is the same as subtracting 0.75 before multiplying).
Result
The result is the approximate percentage score.

This common rule of thumb (CGPA×9.5) is widely accepted for 10-point grading scales.
How to Calculate CGPA to Percentage
Enter CGPA
Use your CGPA from the previous section
Multiply by 9.5
Simply multiply the CGPA by 9.5.
Result
The product is the approximate percentage.
Percentage to SGPA Calculator
This tool does the reverse of SGPA-to-percentage: it finds the SGPA corresponding to a given percentage. Use this if you have a percentage and want an equivalent SGPA on a 10-point scale.
SGPA to Percentage Formula
SGPA = (Percentage ÷ 10) + 7.5
This particular formula corresponds to the one above in reverse.
How to Calculate SGPA to Percentage
Enter Percentage
Start with your percentage score (for one semester).
Apply Formula
Divide the percentage by 10, then add 7.5.
Result
The result is the approximate SGPA.
