How to use the GPA calculator

  1. Choose letter grades for the US 4.0 scale, or numbers for systems such as 1.0–5.0 or percentages.
  2. For each course, pick the grade and enter the credit hours (or ECTS credits).
  3. Add or remove courses – your GPA updates instantly.

How GPA is calculated

Each letter grade is worth a number of grade points. Multiply the points by the course credits, add everything up and divide by the total credits:

GPA = Σ (grade points × credits) ÷ Σ credits

GradePointsGradePoints
A / A+4.0C+2.3
A−3.7C2.0
B+3.3C−1.7
B3.0D+ / D / D−1.3 / 1.0 / 0.7
B−2.7F0.0

Worked example

A (3 credits), B+ (4 credits), A− (3 credits) and C (2 credits):

(4.0 × 3 + 3.3 × 4 + 3.7 × 3 + 2.0 × 2) ÷ 12 = 40.3 ÷ 12 = 3.36.

Weighted and unweighted GPA

Most colleges use the unweighted 4.0 scale above. Many high schools also report a weighted GPA, where honors, AP or IB classes earn an extra point (an A becomes 5.0). Some schools give A+ a value of 4.3. Always check how your school calculates its official GPA.

Cumulative GPA

To combine semesters, enter every course from every term – or enter each semester as one line, using the semester GPA as the grade and its total credits as the weight.

Frequently asked questions

What is a good GPA?
A GPA of 3.0 (a B average) is often considered good, and 3.5 or higher is strong. Competitive universities and scholarships may expect 3.7 or more.
Do pass/fail courses count towards my GPA?
Usually not. Pass/fail courses earn credits but no grade points, so leave them out of the calculation unless your school says otherwise.
How do I raise my GPA?
Courses with more credits have a bigger effect. Good grades in high-credit courses raise your GPA faster than in one-credit classes.
