Understanding Your Overall GPA
Your Overall Grade Point Average (GPA) is a crucial metric that reflects your academic performance over all courses you've taken. It's a single numerical value that summarizes the average of the grades you've earned, weighted by the credit hours of each course. A higher GPA generally indicates stronger academic achievement and can be important for scholarships, graduate school admissions, and certain career opportunities.
How GPA is Calculated
The calculation of your overall GPA involves two main components for each course: the number of credits (or credit hours) and the grade points earned. Grade points are numerical values assigned to letter grades (e.g., A=4.0, B=3.0, C=2.0, D=1.0, F=0.0). Some institutions use a more granular scale (e.g., A-=3.7, B+=3.3).
The formula is as follows:
Overall GPA = (Total Grade Points Earned) / (Total Credit Hours Attempted)
Where:
- Total Grade Points Earned = Sum of (Credits for each course × Grade Points for that course)
- Total Credit Hours Attempted = Sum of (Credits for each course)
Example Calculation
Let's say a student has taken the following courses:
- Course A: 3 Credits, Grade A (4.0 Grade Points)
- Course B: 4 Credits, Grade B (3.0 Grade Points)
- Course C: 3 Credits, Grade A- (3.7 Grade Points)
- Course D: 2 Credits, Grade C (2.0 Grade Points)
Here's how the GPA would be calculated:
- Calculate Grade Points for each course:
- Course A: 3 credits × 4.0 = 12.0 grade points
- Course B: 4 credits × 3.0 = 12.0 grade points
- Course C: 3 credits × 3.7 = 11.1 grade points
- Course D: 2 credits × 2.0 = 4.0 grade points
- Sum Total Grade Points:
12.0 + 12.0 + 11.1 + 4.0 = 39.1 total grade points
- Sum Total Credit Hours:
3 + 4 + 3 + 2 = 12 total credit hours
- Calculate Overall GPA:
39.1 / 12 = 3.2583…
Rounded to two decimal places, the Overall GPA is 3.26.
How to Use This Calculator
Our Overall GPA Calculator simplifies this process for you:
- Enter Course Credits: For each course, input the number of credit hours it's worth (e.g., 3, 4, 0.5).
- Enter Grade Points: Input the numerical grade points you received for that course. Refer to your institution's grading scale (e.g., A=4.0, B=3.0, C=2.0).
- Add More Courses: If you have more than the initial courses shown, click the "Add Another Course" button to add new input rows.
- Remove Courses: If you've added too many or made a mistake, click the "Remove" button next to the respective course.
- Calculate: Once all your courses are entered, click the "Calculate Overall GPA" button.
The calculator will instantly display your cumulative GPA, helping you stay informed about your academic standing.
