A complete step-by-step guide to understanding and calculating your Grade Point Average.
GPA stands for Grade Point Average. It is a standardized way of measuring academic achievement on a numerical scale. Most schools in the United States use a 4.0 scale, where an A earns 4.0 points, a B earns 3.0 points, a C earns 2.0 points, a D earns 1.0 point, and an F earns 0.0 points.
Your GPA matters for college admissions, scholarships, honors programs, graduate school applications, and even some job applications. Understanding how it is calculated gives you the power to track and improve your academic standing.
Before you can calculate your GPA, you need to know how letter grades convert to grade points. Here is the standard 4.0 scale used by most institutions:
| Letter Grade | Grade Points | Percentage |
|---|---|---|
| A+ | 4.0 | 97–100% |
| A | 4.0 | 93–96% |
| 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% |
| C- | 1.7 | 70–72% |
| D+ | 1.3 | 67–69% |
| D | 1.0 | 63–66% |
| D- | 0.7 | 60–62% |
| F | 0.0 | Below 60% |
Follow these four steps to calculate your GPA for any set of courses:
Using the table above, write down the grade point value for each of your courses. For example, an A becomes 4.0, a B+ becomes 3.3, and so on.
Each course has a certain number of credit hours (also called credit units). Multiply the grade points by the credit hours to get quality points for each course.
Quality Points = Grade Points × Credit Hours
Sum the quality points from all your courses to get your total quality points.
Divide the total quality points by the total number of credit hours. The result is your GPA.
GPA = Total Quality Points ÷ Total Credit Hours
Let us walk through a complete example. Suppose you are taking five courses this semester:
| Course | Letter Grade | Grade Points | Credits | Quality Points |
|---|---|---|---|---|
| English 101 | A | 4.0 | 3 | 12.0 |
| Biology 110 | B+ | 3.3 | 4 | 13.2 |
| Math 201 | A- | 3.7 | 3 | 11.1 |
| History 150 | B | 3.0 | 3 | 9.0 |
| Art 100 | A | 4.0 | 2 | 8.0 |
| Totals | 15 | 53.3 | ||
GPA = 53.3 ÷ 15 = 3.55
In this example, the student has a 3.55 GPA, which falls between a B+ and an A- average.
Your semester GPA covers only the courses you took in a single term. Your cumulative GPA includes all courses across all semesters. To calculate your cumulative GPA, simply apply the same four steps using all courses from every semester.

GPA stands for Grade Point Average. It is a numerical representation of your academic performance, typically on a 4.0 scale where A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0.
To calculate your GPA: (1) Convert each letter grade to grade points, (2) Multiply grade points by credit hours for each course, (3) Add up all the quality points, (4) Divide by total credit hours.
Yes, most schools use plus/minus grading. An A- is typically 3.7, a B+ is 3.3, a B- is 2.7, and so on. Check your school's specific grading policy.
A GPA of 3.0 or above is generally considered good. A 3.5 or higher is very good, and a 3.7+ is excellent. However, what counts as "good" varies by context and goals.
