GPA Formula = (∑ (Grade Point × Credits)) / (∑ Credits)
Example Usage: GPA Calculation
Let's calculate a GPA for a semester with the following 4 classes:
| Class | Credits | Grade | Grade Point |
|---|---|---|---|
| Calculus | 4 | A (4.0) | 4.0 |
| Chemistry | 3 | B+ (3.3) | 3.3 |
| English | 3 | A- (3.7) | 3.7 |
| Psychology | 3 | B (3.0) | 3.0 |
To calculate the GPA using this calculator, follow these steps:
- Check the "GPA Mode" checkbox.
- Add 4 rows to the table.
- Enter the grade point values (4.0, 3.3, 3.7, 3.0) in the "Value" column.
- Enter the corresponding credit values (4, 3, 3, 3) in the "Weight" column.
- Click the "Calculate" button.
The calculator will compute the GPA as follows:
- (4.0 × 4) + (3.3 × 3) + (3.7 × 3) + (3.0 × 3) = 16.0 + 9.9 + 11.1 + 9.0 = 46
- Total credits: 4 + 3 + 3 + 3 = 13
- GPA = 46 / 13 = 3.54
The calculator will display a GPA of 3.54.
