How GPA Is Calculated — and What Counts as a Good GPA

Grade Point Average (GPA) is a standardized way of measuring academic performance on a 4.0 scale. It is calculated as the weighted average of your grade points, where each course's grade is multiplied by its credit hours. Courses worth more credits have a proportionally larger impact on your GPA. Most US universities use the 4.0 scale, though some use a 5.0 scale for weighted or honors courses.

Worked Example

A student takes four courses: English (3 credits, A = 4.0), Math (4 credits, B+ = 3.3), History (3 credits, A− = 3.7), Chemistry (4 credits, C+ = 2.3). Quality points: (3×4.0) + (4×3.3) + (3×3.7) + (4×2.3) = 12 + 13.2 + 11.1 + 9.2 = 45.5. Total credits: 3+4+3+4 = 14. GPA = 45.5 ÷ 14 = 3.25.

Standard Letter Grade to GPA Conversion (4.0 Scale)

Letter Grade	Percentage	GPA Points
A+	97–100%	4.0
A	93–96%	4.0
A−	90–92%	3.7
B+	87–89%	3.3
B	83–86%	3.0
B−	80–82%	2.7
C+	77–79%	2.3
C	73–76%	2.0
D	60–69%	1.0
F	Below 60%	0.0

How GPA is calculated

GPA (Grade Point Average) is the weighted average of your grade points across all courses. Each letter grade maps to a point value (e.g. A = 4.0), which is multiplied by the course's credit hours. The sum of all (grade points × credits) is divided by the total credits attempted: GPA = Σ(grade points × credits) ÷ Σ(credits).

Worked example: English (A, 3 credits) + Math (B+, 4 credits) + History (A−, 3 credits) = (4.0×3) + (3.3×4) + (3.7×3) = 12 + 13.2 + 11.1 = 36.3 ÷ 10 = GPA 3.63.

Letter Grade	4.0 Scale	Typical %
A	4.0	93–100
A−	3.7	90–92
B+	3.3	87–89
B	3.0	83–86
B−	2.7	80–82
C+	2.3	77–79
C	2.0	73–76
D	1.0	60–69
F	0.0	Below 60

Frequently Asked Questions

What is GPA?

GPA stands for Grade Point Average. It is a commonly used indicator of academic achievement in schools and universities. It is calculated by dividing the total number of grade points earned by the total number of credit hours attempted.

How is GPA calculated?

GPA is calculated by assigning a numerical value to each letter grade (A=4.0, B=3.0, C=2.0, D=1.0, F=0.0), multiplying by credit hours, summing all points, then dividing by total credit hours.
