How is GPA calculated?

Multiply each course's grade points by its credit hours, sum these, and divide by total credit hours. This calculator does it automatically on a 4.0 scale.

Generally, 3.0 is solid, 3.5+ is strong, and 3.7+ is excellent. Standards vary by program and goal — some scholarships and grad programs expect higher.

Does this calculator account for honors or AP weighting?

No — this uses the standard unweighted 4.0 scale. For weighted classes, use our weighted GPA calculator.

Add your courses, choose a letter grade and credit hours for each, and get your GPA on the standard 4.0 scale instantly.

Your grade point average (GPA) summarizes your academic performance as a single number on a 4.0 scale. This calculator uses the standard letter-grade-to-point mapping below and weights each course by its credit hours.

How GPA is calculated

For each course, your letter grade converts to grade points, which are multiplied by the course's credit hours to give quality points. Your GPA is total quality points divided by total credit hours:

GPA = (Σ grade points × credit hours) ÷ (Σ credit hours)

Standard 4.0 grade scale

Letter	Points	Letter	Points
A / A+	4.0	C	2.0
A-	3.7	C-	1.7
B+	3.3	D+	1.3
B	3.0	D	1.0
B-	2.7	F	0.0

Note: scales vary by institution — some don't use plus/minus grades or treat A+ as 4.0+. Check your school's official policy. For honors/AP weighting, use our weighted GPA calculator.
