|---|---|---|---|
| A+ | 4.00 | C | 2.00 |
| A | 4.00 | C- | 1.70 |
| A- | 3.70 | D+ | 1.30 |
| B+ | 3.30 | D | 1.00 |
| B | 3.00 | D- | 0.70 |
| B- | 2.70 | F | 0.00 |

Frequently Asked Questions
How is GPA calculated?
Your GPA is a weighted average. Multiply each course's grade points by its credit hours to get "quality points," add up all the quality points, then divide by the total number of credit hours. For example, an A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course give (4.0 × 3 + 3.0 × 4) ÷ 7 = 24 ÷ 7 = 3.43.
What is a weighted vs. unweighted GPA?
An unweighted GPA maps every course to the standard 4.0 scale regardless of difficulty. A "weighted" GPA in the credit-hour sense (used here) means each course counts in proportion to its credit hours, so a 4-credit class affects your GPA more than a 1-credit class. Some high schools also add bonus points for Honors or AP courses — that is a separate weighting system.
How do I calculate my cumulative GPA?
A cumulative GPA combines every term you have completed. Enter your prior GPA and the total credits those grades represent in the Cumulative GPA section. The tool converts your prior GPA back into quality points, adds this semester's quality points and credits, and divides to give your overall GPA.
Is this GPA calculator accurate for my school?
It uses the most common U.S. 4.0 letter-grade scale, which matches most colleges and high schools. If your school uses different point values (for example, treating A+ as 4.3 or using plus/minus differently), your official GPA may vary slightly. Always confirm with your registrar for transcript-official numbers.
