GPA Calculator

How do you calculate GPA manually?

GPA uses grade points and credit hours to find an average. Most 4.0 systems use this formula.

Formula:

$GPA = Total Grade Points \div Total Credit Hours$

Step by step Guide:

1. Convert each letter grade into grade points.
2. Multiply each grade point by its credit hours.
3. Add all grade points earned.
4. Add all credit hours.
5. Divide total grade points by total credit hours.

Practical Example:

A 3-credit A gives $4 \times 3 = 12$ points. A 3-credit B gives $3 \times 3 = 9$ points. Total points equal 21, and credits equal 6. So, $21 \div 6 = 3.50$ GPA.

GPA Scale and Letter Grade Conversion

A common 4.0 GPA scale assigns A to 4.0 and B to 3.0. It assigns C to 2.0 and D to 1.0. Plus and minus grades may use different values. Some schools use 4.3 scales or other rules. Always check your school's grading policy before converting a letter grade to GPA. This keeps your result aligned with the official scale.

Weighted GPA vs Unweighted GPA

Weighted GPA gives extra value to harder classes. Unweighted GPA uses the standard scale for each course, without adding extra course weight to the grade.

Note: Weighted GPA rules differ by school. Check your school's grading policy when your transcript includes AP, IB, honors, or other weighted courses.

Cumulative GPA vs Semester GPA

Semester GPA covers one term, while cumulative GPA combines results across multiple terms. Both use grades and credits, but they answer different academic questions.

Note: Your school may use different rules for transfer credits, repeated courses, or grade replacement. Use your official transcript when you need the final GPA.
