How GPA is Calculated

GPA Formula:

GPA = Total Grade Points ÷ Total Credits

Grade Points = Credits × Grade Value

The 4.0 scale is the most common grading system used by colleges. Here's how letter grades convert to GPA points:

Grade Conversion Table

Letter Grade	GPA Value
A+	4.0

A-	3.7
B+	3.3
B	3.0
B-	2.7
C+	2.3
C	2.0
C-	1.7
D+	1.3
D	1.0
F	0.0

Note: Some high schools may use slightly different GPA scales. This calculator uses the standard 4.0 scale used by most colleges.

Example Calculation

Let's say you took three courses this semester:

English (4 credits) - B
Math (5 credits) - A-
History (3 credits) - B+

Here's how to calculate your GPA:

Convert each letter grade to GPA points:
- B = 3.0
- A- = 3.7
- B+ = 3.3
Calculate grade points for each course:
- English: 4 credits × 3.0 = 12.0 points
- Math: 5 credits × 3.7 = 18.5 points
- History: 3 credits × 3.3 = 9.9 points
Sum the grade points: 12.0 + 18.5 + 9.9 = 40.4 points
Sum the credits: 4 + 5 + 3 = 12 credits
Calculate GPA: 40.4 ÷ 12 = 3.366... ≈ 3.37

Your GPA for this semester would be 3.37.
