- Click "Calculate GPA" to see your results
The calculator will show your current GPA and the total number of credits you've earned.
How the 4.0 GPA Scale Works
The 4.0 GPA scale is a weighted grading system where each letter grade corresponds to a specific point value. The formula for calculating GPA is:
GPA = (Total Quality Points) / (Total Credits)
Where Quality Points = (Credits × Grade Point)
For example, an A in a 5-credit course would be 5 × 4.0 = 20 quality points.
Grade Conversion Table
| Letter Grade | Grade Point |
|---|---|
| A+ | 4.0 |
| 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 |
| F | 0.0 |
Example Calculation
Let's say you've taken three courses with the following grades and credits:
- English (5 credits) - B
- Math (4 credits) - A-
- Science (3 credits) - B+
Calculating the quality points:
- English: 5 × 3.0 = 15 quality points
- Math: 4 × 3.7 = 14.8 quality points
- Science: 3 × 3.3 = 9.9 quality points
Total quality points = 15 + 14.8 + 9.9 = 39.7
Total credits = 5 + 4 + 3 = 12
GPA = 39.7 / 12 ≈ 3.31
Frequently Asked Questions
- What is the difference between a 4.0 GPA and a 5.0 GPA?
- The 4.0 scale is the most common, with A being 4.0. The 5.0 scale is less common and uses A as 5.0. Most colleges use the 4.0 scale.
- How many credits should I take per semester?
- Most high schools recommend 5-6 credits per semester for a full-time workload. Check with your school's academic advisor for specific requirements.
- Can I calculate my GPA before I receive all my final grades?
- Yes, you can calculate a preliminary GPA using your current grades. Just be aware that your final GPA may change slightly once all final grades are submitted.
- What is the minimum GPA required for college admission?
- Minimum GPA requirements vary by college. Many competitive schools look for a 3.0 GPA or higher. Check with the colleges you're interested in for their specific requirements.
- How do I calculate weighted GPA?
- Weighted GPA gives extra points to advanced courses. The formula is the same, but you multiply the grade points by the weight factor (usually 1.0 for regular courses and 1.0-1.5 for advanced courses).
