Calculate unweighted, weighted, and cumulative GPA in real-time.
📚 How to Calculate GPA
Calculating your Grade Point Average (GPA) involves three simple steps. First, multiply the grade value of each course by the number of credits that course is worth to find your "Grade Points" for that class. Second, add all your Grade Points together. Finally, divide your Total Grade Points by your Total Credits attempted.
🧮 GPA Formula Explained
The universal mathematical formula used by high schools and colleges is:
⚖️ Weighted vs. Unweighted GPA
An Unweighted GPA measures your grades on a standard 4.0 scale regardless of the difficulty of the classes you take. An A in regular biology is a 4.0, and an A in AP biology is a 4.0.
A Weighted GPA rewards students for taking harder, advanced classes. Honors courses typically add 0.5 points to the standard scale, and AP/IB courses add a full 1.0 point. This means an A in an AP class is worth a 5.0, allowing students to graduate with GPAs higher than 4.0.
📖 GPA to Percentage Conversion Table
| Letter Grade | Percent Range | Regular (4.0) | Honors (+0.5) | AP/IB (+1.0) |
|---|---|---|---|---|
| A+ / A | 93 - 100% | 4.0 | 4.5 | 5.0 |
| A- | 90 - 92% | 3.7 | 4.2 | 4.7 |
| B+ | 87 - 89% | 3.3 | 3.8 | 4.3 |
| B | 83 - 86% | 3.0 | 3.5 | 4.0 |
| B- | 80 - 82% | 2.7 | 3.2 | 3.7 |
| C+ | 77 - 79% | 2.3 | 2.8 | 3.3 |
| C | 73 - 76% | 2.0 | 2.5 | 3.0 |
| C- | 70 - 72% | 1.7 | 2.2 | 2.7 |
| D+ | 67 - 69% | 1.3 | 1.8 | 2.3 |
| D | 65 - 66% | 1.0 | 1.5 | 2.0 |
| F | Below 65% | 0.0 | 0.0 | 0.0 |
🏆 What is a Good GPA?
A "good" GPA depends heavily on your academic level and future goals. A 3.0 GPA (a B average) is generally considered the baseline for a solid academic record. However, highly competitive colleges and universities often look for an Unweighted GPA of 3.7 or higher, and a Weighted GPA above 4.0.
