How GPA is calculated
Your GPA is a weighted average: each letter grade converts to grade points on a 4.0 scale (A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, D- = 0.7, F = 0). Each course's grade points are multiplied by its credit hours, the results are added up, and that total is divided by your total credit hours. Because of the weighting, a 4-credit class moves your GPA twice as much as a 2-credit class with the same grade — which is why protecting your grade in heavy courses matters most. This calculator uses the standard unweighted 4.0 scale used by most US colleges; it does not add extra points for honors or AP classes the way some high schools do with weighted GPAs.
Frequently asked questions
What is a good GPA?
It depends on your goals. A 3.0 is generally considered solid, 3.5+ is competitive for most graduate programs and scholarships, and 3.7+ opens doors at highly selective schools and employers. Context matters too — a 3.4 in a demanding major can impress more than a 3.9 in an easy one.
How do plus and minus grades affect my GPA?
On the standard scale used here, a B+ (3.3) is worth noticeably more than a B (3.0) or B- (2.7). Over several courses, those pluses and minuses add up — borderline grades are worth fighting for.
What is the difference between weighted and unweighted GPA?
Unweighted GPA caps at 4.0 and treats every class equally. Weighted GPA gives bonus points (often +0.5 or +1.0) for honors, AP, or IB classes, so it can exceed 4.0. This calculator uses the unweighted 4.0 scale.
If I retake a class, does the old grade disappear?
Policies vary by school. Many colleges replace the old grade with the new one in your GPA calculation, while others average the two attempts. Check your school's academic policy — retaking a class you failed is often the fastest way to repair a GPA.
