How to Calculate CGPA and Convert to Percentage with Examples
CGPA Calculator
What is CGPA Calculator?
A CGPA Calculator is an academic tool that helps you quickly compute your Cumulative Grade Point Average (CGPA) from subject-wise grades or SGPAs (Semester Grade Point Averages). CGPA is widely used in Indian schools (CBSE, ICSE, universities) and measures your overall academic performance on a scale of 0 to 10. With this CGPA calculator, you can instantly get your average grade, as well as convert it to a percentage, making it easier to interpret your academic results for school leaves, mark-sheets, college forms, and job applications.
Formula or Logic Behind CGPA Calculator
To calculate CGPA, simply add the grade points earned in all major subjects and divide by the total number of subjects. The formula is:
CGPA = (Sum of Grade Points in all Subjects) ÷ (Number of Subjects)
To convert CGPA to percentage (for CBSE):
Percentage = CGPA × 9.5
Do note, the multiplication factor (here 9.5) may vary as per your education board or university. If your institution uses subject credits, multiply each grade by its credit before averaging.
