GPA Calculator
Calculate Semester Grade Point Average (SGPA), Cumulative GPA (CGPA), and percentage conversions using the University Grants Commission (UGC) 10-point Choice Based Credit System (CBCS) and US 4.0 scale.
Under the University Grants Commission (UGC) Choice Based Credit System (CBCS), semester GPA (SGPA) is computed by weighting individual subject grade points against their respective credit allocations ($SGPA = \sum (C_i \times G_i) / \sum C_i$), ensuring high-credit core subjects carry proportionate academic impact.
Calculate GPA, percentage, total marks, and grade instantly.

Add Courses & Credit Weights
Enter the course name and credit value (e.g. 4 credits for core theory, 2 credits for lab).
Input Letter Grade / Grade Points
Select your achieved letter grade (O, A+, A, B+) or direct numerical score.
Compute Weighted SGPA
Instantly view your weighted semester GPA, total credits earned, and official percentage equivalent.
Credit-Weighted SGPA Formula
SGPA = frac{sum_{i=1}ⁿ (C_i × G_i)}{sum_{i=1}ⁿ C_i}
Multiply each course's credit weight ($C_i$) by its earned grade point ($G_i$). Sum these weighted products and divide by the total number of enrolled semester credits.
Example Calculation
Input: Math (4 credits, Grade A = 8) + CS Lab (2 credits, Grade O = 10)
Output: Weighted Points = (4×8) + (2×10) = 32 + 20 = 52 | Total Credits = 6 → SGPA = 52 ÷ 6 = 8.67

Frequently Asked Questions
Verified answers to essential calculation and diagnostic questions.
Under standard UGC and AICTE guidelines, the formula for converting a 10-point scale SGPA/CGPA into an aggregate percentage is: $\text{Percentage (\%)} = (\text{CGPA} - 0.75) \times 10$ or for CBSE/VTU systems: $\text{Percentage} = \text{CGPA} \times 9.5$. Always consult your university's official conversion certificate.
In a Choice Based Credit System (CBCS), a 4-credit course carries twice the mathematical weight of a 2-credit lab course. Scoring a high grade point in a 4-credit subject elevates your semester SGPA significantly more than excelling in a 1-credit elective.
Credential evaluators like World Education Services (WES) do not simply divide by 2.5. Instead, each individual course grade is mapped: 10/9 (A = 4.0), 8 (B = 3.0), 7 (C = 2.0), 6 (D = 1.0), and <6 (F = 0.0), which are then credit-weighted into a 4.0 GPA.
The Choice Based Credit System (CBCS) in Indian Higher Education
Adopted across Indian central and state universities under the University Grants Commission (UGC), the Choice Based Credit System standardizes evaluation through continuous internal assessment and semester-end examinations.
