How Is GPA Calculated?
GPA is calculated by multiplying each course’s grade points by its credit hours then dividing the total by total credit hours. This is called a weighted GPA and ensures courses worth more credits have a greater impact on your overall average.
Formula: GPA = Sum of (Grade Points × Credits) ÷ Total Credits
For example: Maths (A, 3 credits) + English (B+, 3 credits) + Science (A-, 4 credits)
= (4.0×3) + (3.3×3) + (3.7×4) ÷ 10
= (12 + 9.9 + 14.8) ÷ 10
= 3.67 GPA
The 4.0 GPA Scale
A+ / A = 4.0 — Exceptional
A- = 3.7 — Excellent
B+ = 3.3 — Very Good
B = 3.0 — Good
B- = 2.7 — Above Average
C+ = 2.3 — Average
C = 2.0 — Satisfactory
D = 1.0 — Poor
F = 0.0 — Failing
Most universities use this standard 4.0 scale though some institutions use variations. Always check your institution’s specific grading policy.
What Is a Good GPA?
A GPA of 3.0 or above is generally considered good at most universities. A GPA above 3.5 is considered excellent and may qualify you for Dean’s List honours. A GPA above 3.7 is exceptional and is often required for competitive graduate programmes or scholarships.
A GPA below 2.0 at most institutions puts students at risk of academic probation.
FAQs
What is a GPA?
GPA stands for Grade Point Average. It measures your academic performance by converting letter grades to numerical points and calculating a weighted average based on course credits.
What is the difference between semester GPA and cumulative GPA?
Semester GPA only counts the courses from one semester. Cumulative GPA is your overall average across all semesters. Use the Cumulative GPA mode and enter your previous GPA and credits to calculate your overall standing.
How many credits does each course have?
Credit hours vary by course — most standard university courses are 3 credits. Lab courses are often 4 credits. Check your course enrolment information for exact credit values.
What GPA do I need for graduate school?
Most graduate programmes require a minimum GPA of 3.0. Competitive programmes at top universities often expect 3.5 or higher. Some PhD programmes look for 3.7 or above.
Can I raise my GPA in one semester?
Yes — especially if you’re in early semesters. The fewer total credits you have the more impact one strong semester has. Use the Cumulative GPA mode to see exactly what GPA this semester would give you.
