CGPA Calculator

Calculate your Cumulative Grade Point Average (CGPA) across all semesters. Add semester-wise GPA and credit hours to get your overall CGPA, letter grade, and percentage equivalent.

CGPA Formula

CGPA = Σ(GPAi × Creditsi) / Σ(Creditsi)

Each semester's GPA is weighted by its credit hours. Semesters with more credits have a proportionally larger impact on your CGPA. Only semesters with both a GPA and credits entered are included in the calculation.

Example Calculation

A student on a 4.0 scale with three completed semesters:

Sem 1: GPA 3.5 × 18 credits = 63.0 grade points
Sem 2: GPA 3.8 × 20 credits = 76.0 grade points
Sem 3: GPA 3.2 × 16 credits = 51.2 grade points
Total grade points = 190.2 | Total credits = 54
CGPA = 190.2 / 54 = 3.52
Percentage = 3.52 × 25 = 88%

Frequently Asked Questions

CGPA stands for Cumulative Grade Point Average. It is a measure of your overall academic performance across all semesters, calculated as the weighted average of your semester GPAs using credit hours as weights. Unlike a single semester GPA, CGPA reflects your entire academic record.

GPA (Grade Point Average) refers to your performance in a single semester or term, while CGPA is the cumulative average across all semesters. Your CGPA is calculated by weighting each semester's GPA by the number of credits in that semester. A strong CGPA requires consistent performance over your entire program.

Improving CGPA requires consistently high performance in upcoming semesters, as earlier semesters remain fixed. Focus on high-credit courses for maximum impact, retake failed or low-scoring courses if your institution allows grade replacement, and aim for above-average GPA in every semester. The more credits remain, the more opportunity you have to raise your CGPA.

Conversion depends on your grading scale. For the 4.0 scale: Percentage = CGPA × 25. For the 10.0 scale (used in India): Percentage = CGPA × 9.5. These are standard conversion formulas, though some universities may use their own conversion tables. Always check your institution's official conversion guidelines.
