What is a GPA and Why Does It Matter?

Your Grade Point Average (GPA) is a numerical representation of your academic performance. It's calculated by translating your letter grades (A, B, C, etc.) into a numerical scale, typically out of 4.0, and averaging them based on the credit weight of each course.

Understanding your GPA is crucial because it often dictates academic standing, financial aid eligibility, scholarship opportunities, and future college or graduate school admissions. Our GPA Calculator simplifies this complex math.
