What is GPA?

Your Grade Point Average (GPA) is a numerical summary of your academic performance, typically on a 0.0 to 4.0 scale in the U.S. It’s a critical metric for college admissions, scholarships, and personal goal-setting. Understanding how it’s calculated can help you stay on track.

The 4.0 Unweighted GPA Scale

The unweighted 4.0 scale is the most common method in the U.S., treating all courses equally regardless of difficulty. Here’s the breakdown: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0.

GPA = (Sum of Grade Points) ÷ (Total Credit Hours)
Example

English (3 credits, A): 4.0 × 3 = 12.0
Math (4 credits, B): 3.0 × 4 = 12.0
History (2 credits, C): 2.0 × 2 = 4.0

Total: 28.0 ÷ 9 = 3.11 GPA

The Weighted 5.0 GPA Scale

The weighted 5.0 scale rewards harder courses (AP, IB, honors) with extra points, like A = 5.0 instead of 4.0.

AP A

5.0

Advanced courses

Regular A

4.0

Standard courses

Example

AP Bio (4 credits, A): 5.0 × 4 = 20.0
Math (3 credits, B): 3.0 × 3 = 9.0
Honors History (3 credits, C): 3.0 × 3 = 9.0

Total: 38.0 ÷ 10 = 3.80 GPA

Percentage-Based GPA Method

In some countries, grades are percentages (e.g., 85%) converted to a 4.0 scale: 90–100% = 4.0, 80–89% = 3.0, etc.

Example

Subject 1 (92%, 3 credits): 4.0 × 3 = 12.0
Subject 2 (78%, 4 credits): 2.0 × 4 = 8.0
Subject 3 (85%, 2 credits): 3.0 × 2 = 6.0

Total: 26.0 ÷ 9 = 2.89 GPA

10.0 Scale

CGPA = Percentage ÷ 9.5
E.g., 85% ÷ 9.5 = 8.95 CGPA
To 4.0: 8.95 × 0.4 = 3.58
