What is CGPA?
Your cumulative grade point average (CGPA) is the average of all the grade points you have earned across every semester of a program, not just the latest one. It is the figure that appears on your final transcript and degree certificate, and the one used for graduation honours, scholarships, internships and most job applications.
The key detail is weighting. A CGPA is not the simple average of your semester GPAs. A semester in which you took 18 credits counts for more than one with 12, so the calculator multiplies each semester's GPA by its credits before averaging.
How to use the CGPA calculator
- Enter each semester's GPA and the number of credits taken that term. You will find both on your transcript or result card.
- Click Add semester for more terms. To project the future, add an upcoming semester with the GPA you are aiming for.
- Read your CGPA and total credits. Copy the result for your records.
The CGPA formula
CGPA = Σ (semester GPA × semester credits) ÷ Σ credits
This gives exactly the same result as averaging every individual course grade weighted by its credits, because each semester GPA is itself a credit-weighted average.
Many universities in Pakistan, India, Bangladesh and elsewhere use CGPA on a 4.0 scale; some use 5.0 or 10.0. The formula works the same way on any scale, but this calculator accepts GPAs up to 4.3.
Example
Three semesters with GPAs of 3.5 (15 credits), 3.2 (18 credits) and 3.8 (12 credits) give 3.5 × 15 + 3.2 × 18 + 3.8 × 12 = 155.7 quality points over 45 credits, so the CGPA is 3.46. The simple average of the three GPAs would be 3.50, which overstates the result because the weakest semester was also the heaviest.
More worked examples
Adding a strong semester: a 3.2 CGPA over 60 credits plus a 3.8 semester of 15 credits gives (3.2 × 60 + 3.8 × 15) ÷ 75 = 3.32.
Common mistakes to avoid
- Taking a simple average of semester GPAs. Heavier semesters count more.
- Expecting a late boost to move it much. The more credits you have, the less one semester changes your CGPA.
- Mixing scales. Convert percentages first with the percentage to GPA calculator.
