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.

AICTE & UGC Academic NormsReviewed: January 2026
All India Council for Technical Education (AICTE) CGPA Norms
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

Questions about this calculator
CGPA (Cumulative Grade Point Average) is a measure of a student's overall academic performance calculated across all subjects or semesters.
CGPA is calculated by dividing the total weighted grade points by the total credit hours of all subjects.
Many institutions use the formula Percentage = CGPA × 9.5. However, conversion rules may vary by university.
A CGPA above 8.0 is generally considered good, while a CGPA above 9.0 is considered excellent in most academic institutions.
Yes, as long as your institution uses a credit-based grading system. However, percentage conversion rules may differ between universities.
How credit-weighted CGPA works
Each subject's grade point is multiplied by its credit value. The calculator adds those quality points and divides by the total credits, so a high-credit subject affects the result more than a low-credit subject.
CGPA example
If two courses have grade points 8 and 9 with 4 and 2 credits, the CGPA is ((8 × 4) + (9 × 2)) ÷ 6 = 8.33. Enter the grade point shown by your institution rather than a letter grade unless you have converted it using the official scale.
Percentage conversion warning
Universities use different CGPA scales and percentage-conversion rules. A general conversion is not an official transcript result. Check your university handbook, marksheet, or examination office before using a converted percentage in an application.
