How the GPA Calculator Works
Enter each course with its letter grade and credit value. The calculator computes a weighted GPA: each course's grade points are multiplied by its credits, summed, then divided by total credits.
Switch between the 4.0 scale (standard in the US) and the 4.3 scale (used at some Canadian universities, where A+ = 4.3 instead of 4.0). Add or remove courses as needed.
Frequently Asked Questions
How is GPA calculated?
GPA = Σ(grade points × credits) ÷ total credits. For example, an A (4.0) in a 3-credit course and a B (3.0) in a 3-credit course gives GPA = (4.0×3 + 3.0×3) ÷ (3+3) = 3.5.
What is the difference between 4.0 and 4.3 scales?
On the 4.0 scale (US standard), the highest grade is A = 4.0 and A+ also maps to 4.0. On the 4.3 scale (used at some Canadian universities like McGill), A+ maps to 4.3, giving students extra credit for exceptional performance.
What is a good GPA?
On a 4.0 scale, a GPA of 3.5 or above (equivalent to an A−) is generally considered good. A 4.0 GPA means straight A's. Competitive graduate programs often require a 3.5–3.7 minimum.
