GPA Calculator
Add your courses, credits, and letter grades to calculate your GPA on the 4.0 scale — with weighted and unweighted results side by side.
How to read your result
Your unweighted GPA is the classic 4.0-scale average colleges start from; the weighted GPA credits you for taking Honors and AP/IB courses. Because GPA is credit-weighted, a semester-long elective moves it far less than a full-year core course — and one tough semester fades as more credits accumulate. If you are planning AP exams this year, our AP score calculators estimate where you stand on each test.

Frequently Asked Questions
How is GPA calculated?
Each letter grade maps to grade points (A = 4.0, A- = 3.7, B+ = 3.3, and so on down to F = 0). Multiply each course's points by its credits, add everything up, and divide by total credits. A weighted GPA additionally adds a bonus for harder courses — commonly +0.5 for Honors and +1.0 for AP or IB.
What is the difference between weighted and unweighted GPA?
Unweighted GPA treats every course equally on a 4.0 scale. Weighted GPA gives extra points for advanced courses, so it can exceed 4.0. Colleges typically look at both, and many recalculate GPA their own way — so treat the weighted number as a signal of course rigor, not a universal standard.
Do schools all use the same GPA scale?
No. Some schools use A+ = 4.3, some cap at 4.0, some weight Honors differently or use 100-point or 5.0 scales. This calculator uses the most common US convention (A+ capped at 4.0, Honors +0.5, AP/IB +1.0). Check your school profile or handbook for its exact policy when precision matters.
How can I raise my GPA?
GPA moves slowly because it averages everything, so target the biggest levers: courses you're currently borderline in, and high-credit courses. Studying with active recall and spaced repetition — flashcards reviewed on a schedule instead of rereading notes — is the most evidence-backed way to convert study time into exam points.
