GPA Calculator
Add each course’s credit hours and grade to get your weighted GPA on a standard 4.0 scale.
How is weighted GPA calculated?
A weighted GPA doesn’t just average your grades — it weights each grade by how many credit hours the course was worth, so a 4-credit course affects your GPA twice as much as a 2-credit course. That’s why it’s called "weighted": total grade points earned, divided by total credit hours attempted.
Frequently asked questions
How is weighted GPA different from a simple average?
A simple average treats every course equally regardless of credit hours. Weighted GPA multiplies each course's grade points by its credit hours, sums those, then divides by total credits — so a 4-credit A counts more toward your GPA than a 1-credit A.
What is the standard 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, F = 0.0. This is the most common U.S. scale, though some schools use slightly different values for plus/minus grades.
What if my school's scale is different?
Some institutions don't use +/- grades at all, or weight them slightly differently (e.g. A- as 3.67 instead of 3.7). Check your school's official grading policy if you need an exact match — this calculator uses the most widely used standard scale.
Does this account for honors or AP course weighting?
No — some high schools add extra weight for honors/AP/IB courses (e.g. an A in an AP class counts as 5.0 instead of 4.0). This calculator uses the standard unweighted 4.0 scale; if your school weights advanced courses, adjust the grade point value for those courses manually before entering them.
Uses a standard 4.0 scale (A = 4.0 … F = 0.0). Some schools weight honors/AP courses differently — check your institution’s scale if it’s not standard.
