GPA Terms Glossary: Weighted, Unweighted, Quality Points & Scale Caps

July 15, 2026

GPA math uses a handful of terms that get used loosely in everyday conversation but have precise meanings. Here’s what each one means for the GPA calculator.

Grade Points

The numeric value assigned to a letter grade on a 4.0 scale — A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0, with plus/minus grades typically at 0.3 or 0.33 increments (A- = 3.7, B+ = 3.3, and so on). Grade points are what actually get averaged; the letter grade itself is just a label for the underlying point value.

Quality Points

A course’s grade points multiplied by its credit hours — the actual number added into the GPA formula’s numerator. A 4-credit A contributes 16 quality points (4.0 × 4); a 2-credit A contributes 8 (4.0 × 2). GPA is the sum of quality points across all courses divided by the sum of credit hours, not a simple average of letter grades.

Unweighted GPA

GPA calculated on a flat 0.0-4.0 scale regardless of course difficulty — an A is worth 4.0 whether it’s earned in a standard class or an AP class. This is the most straightforward, most comparable version of GPA across different schools.

Weighted GPA

GPA where harder courses (Honors, AP, IB, dual-enrollment) earn a bonus grade point before averaging — commonly +0.5 for Honors and +1.0 for AP/IB in US high schools, though the exact bonus varies by school. Weighted GPA can exceed 4.0, sometimes approaching 5.0 for a heavy AP course load. See the GPA calculator’s Weighted GPA toggle to apply this automatically.

Cumulative GPA

The credit-hour-weighted GPA across every term completed so far, as opposed to a single semester or year’s GPA. Combining a new semester into an existing cumulative GPA uses total quality points across all terms, not an average of each term’s separate GPA — see common GPA calculation mistakes for why averaging term GPAs directly produces the wrong number.

GPA Scale Cap

The maximum value a school allows GPA to reach, regardless of how many bonus points a student’s courses would otherwise add up to. Some high schools cap weighted GPA at 4.5 or 5.0; some colleges recalculate an applicant’s GPA using their own scale and their own cap, which can differ significantly from the number on a student’s actual transcript. See GPA calculator for college applications for how specific colleges apply their own caps and formulas.

Recalculated GPA

A GPA a college computes itself from an applicant’s transcript, using the college’s own rules for which courses count and how much weighting bonus applies — rather than accepting the GPA printed on the transcript or self-reported by the student. Recalculated GPA is common practice at large public university systems and can be noticeably different (usually lower) than a student’s official transcript GPA, since colleges often exclude non-academic courses (PE, electives) and use their own honors-point rules.

A-G Courses

A specific list of college-preparatory course categories (English, math, lab science, foreign language, social studies, and others) used by some university systems, most notably the University of California, to determine which courses count toward GPA at all. Courses outside the A-G list — including many electives — are excluded from an A-G GPA calculation even if they appear on the student’s transcript and count toward a standard school GPA.
