GPA Calculator

Each letter grade maps to a grade point — A is 4.0, B is 3.0, and each plus or minus moves it by 0.3. Multiply that grade point by the course credit hours to get quality points, add the quality points for every course, then divide by the total credit hours. The divisor is the credit total, never the number of courses, which is why a 4-credit A outweighs a 1-credit A.

An unweighted GPA puts every course on the same 4.0 table, so an A is 4.0 whether it came from an AP class or a regular one. A weighted GPA adds a bonus for harder courses — usually 1.0 for AP and IB and 0.5 for honours — which pushes the top of the scale to 5.0. Colleges often recalculate an unweighted figure of their own, so it is worth knowing both.

Write each course as a name, a colon, the letter grade, and the credit hours, then separate the courses with semicolons: "Organic Chemistry: A-, 4; English Composition: A, 3". The parser anchors on the colon, so multi-word course names stay in one piece even if a paste from a spreadsheet has collapsed the line breaks into spaces. If you leave the credit hours off, the course counts as one credit.

It converts your previous GPA back into quality points by multiplying it by the credits you had already earned, adds this term’s quality points and credits, and divides again. That is exactly what a registrar does, and it is why one strong term moves a large transcript only slightly.

Pass/fail and withdrawn courses normally earn credit without grade points, so they sit outside the GPA entirely — leave them off the list. A repeated course depends on your school: some replace the old grade, in which case list only the new one, while others average both attempts, in which case list both.
