How GPA is calculated
Each letter grade is worth a number of grade points. Multiply each class's points by its credits, add them up, and divide by the total credits:
GPA = Σ (grade points × credits) ÷ Σ credits
Example: an A in a 4-credit class, a B in a 3-credit class and a C+ in a 3-credit class gives (4.0 × 4 + 3.0 × 3 + 2.3 × 3) ÷ 10 = 3.19.

Percentage ranges differ between schools; your grade points come from the letter on your report card.
Weighted GPA
Weighted GPA rewards harder classes by adding a bonus to the grade points. The most common system, used here, adds 0.5 for Honors and 1 for AP, IB and dual-enrollment classes, so an A in AP counts as 5.0. Failing grades get no bonus. Your school may use a different bonus or cap, so check your handbook if the exact figure matters.
What is the difference between weighted and unweighted GPA?+
Unweighted GPA uses the same 4.0 scale for every class. Weighted GPA adds a bonus for harder classes — commonly +0.5 for Honors and +1 for AP, IB or dual-enrollment — so it can go above 4.0.
Do colleges use weighted or unweighted GPA?+
Both, and many recalculate it their own way. Report what your school reports, and expect admissions offices to look at the rigor of your classes alongside the number.
How do credits affect GPA?+
Each grade counts in proportion to its credits. A 4-credit A lifts your GPA more than a 1-credit A. If your school gives every class the same weight, leave credits at 1.
Is an A+ worth more than 4.0?+
On the standard scale used here, no — A+ and A are both 4.0. Some schools give A+ 4.3; if yours does, add the difference yourself or check your transcript.
How do I calculate my cumulative GPA?+
Multiply each term's GPA by its credits, add them up, and divide by the total credits. Enter your GPA and credits so far under "cumulative GPA" and the calculator does it for you.
