How a 4.0 GPA Is Calculated
Each letter grade is worth a set number of grade points on the 4.0 scale. Multiply each course's points by its credit hours, add everything up, then divide by total credits. In one line: GPA = total grade points ÷ total credits.
The standard grade point table
| Grade | Points | Grade | Points |
|---|---|---|---|
| A | 4.0 | C | 2.0 |
| A− | 3.7 | C− | 1.7 |
| B+ | 3.3 | D+ | 1.3 |
| B | 3.0 | D | 1.0 |
| B− | 2.7 | D− | 0.7 |
| C+ | 2.3 | F | 0.0 |
Weighted vs. unweighted
An unweighted GPA tops out at 4.0 no matter how hard the class was. A weighted GPA gives tougher courses a bump, commonly +0.5 for honors and +1.0 for AP or IB, so a B in AP Chemistry counts like an A in a regular section. One standard exception: an F earns zero points in any class, weighted or not. The calculator applies both rules and shows the two numbers side by side whenever an honors or AP course is in the mix.
A quick example
Say you took 4 credits of A (4.0), 3 credits of B+ (3.3), and 3 credits of B (3.0). Grade points: 4 × 4.0 + 3 × 3.3 + 3 × 3.0 = 34.9. Divide by 10 credits and your GPA is 3.49.
One honest caveat
Schools differ on details. Some award 4.3 for an A+, some weight honors courses their own way. The scale here is the common convention, which is what most GPA conversations assume. For anything official, like a transcript or an application, check the result against your school's published policy. Working toward a target grade in one specific class? That's what the grade calculator is for.
