The GPA Formula Explained
The basic GPA formula is straightforward: divide the total grade points earned by the total credit hours attempted. Here's the formula:
GPA = Total Grade Points ÷ Total Credit Hours
For example, if you earned 45 grade points across 15 credit hours, your GPA would be 45 ÷ 15 = 3.0
Standard GPA Grading Scale
Most institutions in the United States use the 4.0 grading scale. Here's how letter grades convert to grade points:
- A = 4.0 (Excellent)
- A- = 3.7
- B+ = 3.3
- B = 3.0 (Good)
- B- = 2.7
- C+ = 2.3
- C = 2.0 (Average)
- C- = 1.7
- D+ = 1.3
- D = 1.0 (Below Average)
- F = 0.0 (Fail)
Step-by-Step GPA Calculation
Let's calculate GPA with a real example. Suppose you completed these courses:
- Mathematics (3 credits) - Grade: A (4.0)
- English (3 credits) - Grade: B+ (3.3)
- Science (4 credits) - Grade: B (3.0)
- History (3 credits) - Grade: A- (3.7)
Step 1: Calculate Grade Points for Each Course
- Mathematics: 3 × 4.0 = 12.0 points
- English: 3 × 3.3 = 9.9 points
- Science: 4 × 3.0 = 12.0 points
- History: 3 × 3.7 = 11.1 points
Step 2: Add Total Grade Points
Total Grade Points = 12.0 + 9.9 + 12.0 + 11.1 = 45.0
Step 3: Add Total Credit Hours
Total Credits = 3 + 3 + 4 + 3 = 13
Step 4: Divide to Get GPA
GPA = 45.0 ÷ 13 = 3.46
