CGPA Calculator
Calculate your CGPA (Cumulative Grade Point Average) and convert it into percentage instantly. Add grades and credits for multiple subjects to get accurate results.
Cumulative Grade Point Average (CGPA) computes your aggregate academic performance across all completed semesters by weighting each semester's SGPA against total semester credits ($CGPA = \sum (S_j \times C_j) / \sum C_j$). It serves as the definitive metric for degree honors, gatekeeper corporate cutoffs, and postgraduate university admissions.

Formula: Percentage = (CGPA - 0.75) × 10For Indian engineering and technical degrees, AICTE circular guidelines standardize conversion to percentage using: $\text{Percentage} = (\text{CGPA} - 0.75) \times 10$. For a 8.0 CGPA, the official percentage equivalent is $(8.0 - 0.75) \times 10 = 72.5\%$.

CGPA Formula
CGPA = Σ(Grade Point × Credit Hours) ÷ Σ(Credit Hours)
CGPA (Cumulative Grade Point Average) is calculated by multiplying the grade point earned in each subject by its credit hours, summing all values, and dividing by the total credit hours.
Example Calculation
Input: Subject 1: GPA 8.5, Credits 4 | Subject 2: GPA 9.0, Credits 3 | Subject 3: GPA 8.0, Credits 3
Output: CGPA = (8.5×4 + 9.0×3 + 8.0×3) ÷ (4+3+3) = 8.5
