About

Grade Point Average (GPA) is a standard measure of academic achievement used by schools and universities worldwide. It represents the average of your grades weighted by course credits. A higher GPA reflects stronger academic performance and can affect scholarship eligibility, graduate school admissions, and job applications.

How to Use

Enter each course name, the number of credits (weight), and select the letter grade you received.

How GPA Is Calculated

GPA is the weighted average of your grades. Each letter grade converts to a numerical grade point (A = 4.0, B = 3.0, etc.). Multiply each course's grade points by its credits, sum them up, then divide by the total credits.

Formula: GPA = Σ(Credits × Grade Points) ÷ Σ(Credits)

Grade Scale

Each letter grade corresponds to a numerical grade point value used in the calculation:

GradeGrade Points
A+4.0
A4.0
A-3.7
B+3.3
B3.0
B-2.7
C+2.3
C2.0
C-1.7
D+1.3
D1.0
D-0.7
F0.0

Examples

Balanced Semester

A student takes Math (4 credits, A), Physics (3 credits, B+), and English (3 credits, A-). Math contributes 4 × 4.0 = 16.0 points, Physics contributes 3 × 3.3 = 9.9 points, and English contributes 3 × 3.7 = 11.1 points. Total points = 37.0, total credits = 10. The GPA is 3.70.

Heavy Credit Load

A science major takes Biology (4 credits, A-), Chemistry (4 credits, B), Lab (1 credit, A+), and Calculus (3 credits, B+). The higher-credit courses have more influence on the final GPA. Weighted properly, the result is 3.39.

Graduation Requirement

An engineering student needs a minimum 3.0 GPA to graduate. After six courses worth 18 credits, they earned 58.5 grade points. Dividing 58.5 by 18 gives a GPA of 3.25, comfortably above the threshold.

FAQ

What is a good GPA?
A GPA of 3.0 or higher is generally considered good. A 3.5 or above is excellent and may qualify for honors programs or scholarships. Many graduate programs require a minimum 3.0 for admission.
How are weighted and unweighted GPAs different?
An unweighted GPA treats all courses equally on a 4.0 scale. A weighted GPA gives additional points for honors, AP, or IB courses, potentially exceeding 4.0. This calculator uses the standard unweighted 4.0 scale.
Can I calculate my cumulative GPA?
Yes. Enter all courses from previous and current semesters. The calculator sums all grade points and divides by total credits to give your cumulative GPA across all terms.
What does each letter grade mean?
A = Excellent (4.0), B = Good (3.0), C = Average (2.0), D = Below Average (1.0), F = Failing (0.0). Pluses and minuses adjust the value by 0.3 up or down.
How do I raise my GPA?
Focus on courses with higher credit weights; they impact your GPA more. Retaking low-grade courses can replace the grade in many schools. Consistent study habits and attending office hours also help improve performance.
What is a pass/fail course?
Pass/fail courses earn credit without a letter grade and typically do not affect GPA. They appear on transcripts as a pass (P) or fail (F), but most schools exclude them from GPA calculations.
What if my school uses a different point scale?
This calculator uses the standard unweighted 4.0 scale where A+ = 4.0. Some schools assign A+ a value of 4.3, which can produce a maximum GPA above 4.0. If your institution uses a different scale (4.3, 5.0, 10.0, or percentage-based), the letter-grade point values on this page will not match your transcript. Check with your registrar for your school's official grade-point equivalents.
