Tips for Better Results
- CGPA = total grade points ÷ total credit hours. A higher-credit course moves your average more.
- Enter your previous CGPA and credits to roll past semesters into one cumulative result.
- On the 10.0 scale, percentage ≈ CGPA × 9.5 (the standard CBSE conversion).
- An F still counts its credits with 0 points, so it pulls the average down — retaking the course helps.
How to use
- Pick your grading scale: 4.0, 5.0 or 10.0.
- Optionally enter your previous CGPA and total credits from past semesters.
- Add each course with its credit hours and the grade you earned.
- Click Calculate CGPA to see your result, grade points and percentage equivalent.

About This Tool
Introduction
Your GPA decides scholarships, admissions, and job shortlists—but computing it by hand across credit hours and grading scales is tedious and error-prone. Trencada's CGPA Calculator computes your Cumulative Grade Point Average in seconds. It supports the three most common grading scales worldwide: 4.0 (US universities), 5.0 (Nigeria), and 10.0 (India), and folds in your previous semesters for a true cumulative result. Everything runs in your browser—no signup, no uploads, your grades never leave your device.

Yes—select the 10.0 scale for grades O through F, with percentage conversion using the standard CGPA × 9.5 formula.
3. Can I combine previous semesters into one result?
Yes. Enter your previous CGPA and total previous credits in the optional fields, and the tool rolls them together with your new courses into a single cumulative CGPA.
4. What do the performance labels mean?
The label reflects your percentage equivalent: Outstanding (90%+), Excellent (75%+), Good (60%+), Satisfactory (50%+), or Needs improvement (below 50%).
