GPA Calculator

What This GPA Calculator Does

Your GPA (grade point average) turns all your letter grades into one number on a 4.0 scale, where an A is 4, a B is 3, and so on. But it is not a plain average: each class is weighted by its credit hours, so a 4-credit course pulls on your GPA twice as hard as a 2-credit one.

Enter each course’s grade and credits, add as many as you need, and the GPA updates automatically - the credit-weighted average of all your grade points.

How GPA Is Calculated

$$\begin{aligned} \text{grade points} &= \text{grade value} \times \text{credit hours} \\ \text{GPA} &= \frac{\text{total grade points}}{\text{total credit hours}} \end{aligned}$$

The 4.0 Grade Scale

Grade	Points	Grade	Points
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	D-	0.7
C+	2.3	F	0.0

How to Use It

1. Pick each course’s grade and enter its credit hours.
2. Use Add course for more rows (and Remove to delete one).
3. Read your GPA and total credits.

Worked Example

Course	Grade	Credits	Grade points
1	A (4.0)	3	12
2	B+ (3.3)	4	13.2
3	B (3.0)	3	9

Total grade points $34.2 \div 10$ credits = 3.42 GPA.

FAQ

How is GPA calculated?

Multiply each course’s grade value by its credit hours, add those up, and divide by the total credit hours. Credits weight the result, so a 4-credit class counts more than a 1-credit one.

How do I calculate a cumulative GPA?

Enter every course across all terms (or each term’s totals). The tool divides total grade points by total credits, which is the cumulative GPA.

What about a weighted (honors/AP) GPA?

Some schools add extra points for honors or AP classes (for example, an A counts as 5.0). Enter the adjusted grade value for those courses if your school uses a boosted scale.

Is the 4.0 scale the only one?

It is the most common in the US. Other scales exist, so check your school’s official scale if it differs.
