GPA Calculator
Add each course with its letter grade and credit hours to get your weighted grade point average on the standard US 4.0 scale. Results update as you type — nothing is uploaded.
GPA = total quality points ÷ total credit hours, where each course's quality points are its grade-point value (A=4.0, B=3.0, C=2.0, D=1.0, F=0) times its credit hours. Example: an A in a 3-credit course and a B in a 1-credit course give (4.0×3 + 3.0×1) ÷ 4 = 3.75; add each course's grade and credits to see your weighted average.
Add at least one course with credit hours.

Weighted GPA adds the typical bump for course difficulty (Honors +0.5, AP/IB +1.0). Schools vary — check yours.
How to use the GPA calculator
For each class, pick the letter grade you earned and type how many credit hours it was worth. The course name is optional and just helps you keep track. Your GPA, total credit hours, and total quality points update instantly. Use + Add course to add more rows, or the × button to remove one. Rows left with blank or zero credits are ignored, so an empty row won't change your result.
How GPA is calculated on the 4.0 scale
Each letter grade maps to a number of grade points. Your GPA is the credit-hour-weighted average of those points:
- Multiply each course's grade points by its credit hours to get its quality points.
- Add up the quality points from every course.
- Divide that total by your total credit hours.
For example, an A (4.0) in a 3-credit course and a B (3.0) in another 3-credit course give 12 + 9 = 21 quality points over 6 credit hours, for a GPA of 3.50. A course worth more credit hours pulls your average toward its grade more strongly than a smaller course.

Grade points on the standard US 4.0 scale
| Letter grade | Grade points |
|---|---|
| A+ / 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 |
| D- | 0.7 |
| F | 0.0 |
Schools vary: some don't award an A+ above 4.0, some omit minus grades, and weighted/honors courses may use a 5.0 scale. This calculator uses the common unweighted 4.0 scale shown above. Check your school's official policy for transcript GPA.
Common GPA questions
What is a good GPA? On the 4.0 scale, a 3.0 is roughly a B average and a 3.5+ is often considered strong, but expectations vary by school and program.
Why does each course count differently? Because GPA is weighted by credit hours. A 4-credit class influences your average more than a 1-credit class with the same grade.
Can I calculate a semester or cumulative GPA? Yes — add this semester's courses for a semester GPA, or list every course you've taken for a cumulative GPA.
