How to Use This Calculator
Choose Grade Format
Toggle between Letter grades (A, B) or Percentage (95%) using the buttons in the settings panel above the courses.
Add Your Courses
Enter the course name, grade, and credit hours. Most standard college courses are 3 or 4 credits. The calculator multiplies your grade by the credits automatically.
Include Previous History
If you aren't a freshman, open the "Prior History" tab. Enter your prior cumulative GPA and total credits earned to see how this semester affects your grand total.
What is GPA?
GPA stands for Grade Point Average. It is a standardized way of measuring academic achievement in the U.S. It converts your letter grades (A, B, C) into a numerical scale (usually 0.0 to 4.0) so colleges and employers can easily see how well you did across all your classes.
The 4.0 Scale
An 'A' is worth 4 points, a 'B' is 3 points, etc. This makes comparing students from different grading systems fairer.
Credit Weighting
In college, GPA is weighted by credit hours. A 4-credit Lab class affects your GPA much more than a 1-credit PE class.

What is a "Good" GPA?
The average college GPA in the U.S. is approximately 3.15. However, "good" is entirely subjective to your major and your post-grad goals.
4 Ways to Improve Your GPA
1. Retake Classes
If your college allows grade replacement, retaking a 'D' or 'F' class is the fastest mathematical way to boost your GPA.
2. Balance Your Schedule
Pad your schedule. Balance difficult 4-credit major requirements with easier 3-credit electives.
3. Avoid "W" Grades
While a "W" (Withdraw) doesn't hurt your numerical GPA, a transcript full of them looks bad to grad schools.
4. Office Hours
Building rapport with professors often leads to better understanding of grading criteria and leniency on edge-case grades.
