How do I calculate my cumulative GPA?

To calculate cumulative GPA: 1) Multiply each course's grade points by its credits to get quality points, 2) Add all quality points together, 3) Divide by total credits attempted. For weighted GPA, add extra points (typically +1.0) for Honors, AP, or IB courses.

What is the difference between weighted and unweighted GPA?

Unweighted GPA uses a 0-4.0 scale where A=4.0 regardless of course difficulty. Weighted GPA uses a 0-5.0 scale and adds bonus points (commonly +1.0) for advanced courses like Honors, AP, or IB classes, so an A in AP might count as 5.0.

How do percentages convert to GPA on a 4.0 scale?

Common conversion: 90-100%=A (4.0), 80-89%=B (3.0), 70-79%=C (2.0), 60-69%=D (1.0), below 60%=F (0.0). Note that specific conversions can vary by institution, so check your school's grading policy.

What is a good GPA for college admissions?

For most colleges, a 3.0 GPA (B average) is considered acceptable. Competitive colleges typically look for 3.5+, while elite institutions often expect 3.8-4.0. However, GPA is just one factor - test scores, extracurriculars, and essays also matter.

Frequently Asked Questions

What is a good GPA in the US?

A GPA of 3.0 (B average) is generally considered acceptable for most colleges. A 3.5+ is considered strong and competitive, while 3.8-4.0 is excellent for top-tier universities. However, admissions consider many factors beyond GPA including test scores, extracurriculars, essays, and recommendations.

How is weighted GPA different from unweighted?

Unweighted GPA uses a 0-4.0 scale where all courses are valued equally. Weighted GPA uses a 0-5.0 scale and gives extra credit (typically +1.0) for advanced courses like Honors, AP (Advanced Placement), or IB (International Baccalaureate). This rewards students who take more challenging courses.

Does this calculator store my data?

No, absolutely not. All calculations happen entirely in your web browser using JavaScript. We don't collect, store, or transmit any of your grade information. Your data stays completely private on your device.

How do I calculate semester vs cumulative GPA?
