This GPA Calculator — also a full grade point average calculator, grade calculator, and quality points calculator in one — turns a list of courses, credit hours, and letter grades into your semester GPA on the standard 4.0 scale calculator basis, and can combine that with a previous GPA and credit total to produce your updated cumulative GPA. Whether you need a high school GPA calculator for weighted honors and AP classes, a college GPA calculator or university GPA calculator for a single term, or a simple class GPA calculator to check one course's impact, it's built for students planning a course load, checking academic standing, or figuring out what grades they need to hit a target GPA.
Each course you add gets a Quality Points value equal to its Credit Hours multiplied by its Grade Point — this is the letter grade to GPA conversion (A = 4.0, A- = 3.7, B+ = 3.3, and so on down to F = 0.0). Acting as a semester GPA calculator, it sums the quality points and credit hours across every course, then divides: Semester GPA = Total Quality Points ÷ Total Credit Hours, correctly weighting courses by their credit hours so GPA reflects how much each class actually counts. If you fill in a previous GPA and previous credit total, this cumulative GPA calculator recombines everything into Cumulative GPA = (Previous GPA × Previous Credits + This Semester's Quality Points) ÷ (Previous Credits + This Semester's Credits), correctly weighting older and newer coursework by how many credit hours GPA math assigns to each.
Worked example — using the three default courses this GPA calculator loads: a 3-credit course graded A (4.0), a 3-credit course graded B+ (3.3), and a 4-credit course graded A- (3.7). Step 1: find each course's quality points (Credit Hours × Grade Point) — 3 × 4.0 = 12.0, 3 × 3.3 = 9.9, and 4 × 3.7 = 14.8. Step 2: add the quality points and the credit hours separately — total quality points = 12.0 + 9.9 + 14.8 = 36.7, and total credit hours = 3 + 3 + 4 = 10. Step 3: divide — Semester GPA = 36.7 ÷ 10 = 3.67, which is exactly what this grade calculator shows when you click Calculate GPA on the default rows. Now say you also enter a previous GPA of 3.4 across 60 previous credit hours in the Cumulative GPA section: this cumulative GPA calculator combines it as Cumulative GPA = (3.4 × 60 + 36.7) ÷ (60 + 10) = (204 + 36.7) ÷ 70 = 240.7 ÷ 70 = 3.44 — a clear illustration of how a strong or weak semester pulls a long-running college GPA calculator or university GPA calculator total up or down.
GPA affects academic standing, scholarship eligibility, honor roll and Dean's List qualification, graduate school admissions, and sometimes job applications, so understanding exactly how a grade in a specific class moves the number helps with course-load planning — for example, deciding whether to retake a class, drop a course, or take on an extra credit-heavy class to offset a weaker grade. Knowing how to calculate GPA by hand also makes it easier to spot-check your official transcript.
The scale used by this calculator — the most common standard across US colleges and high schools
| Letter Grade | Grade Point | Letter Grade | Grade Point |
|---|---|---|---|
| A / A+ | 4.0 | C+ | 2.3 |
| A- | 3.7 | C | 2.0 |
| B+ | 3.3 | C- | 1.7 |
| B | 3.0 | D+ | 1.3 |
| B- | 2.7 | D | 1.0 |
| D- | 0.7 | ||
| F | 0.0 |
Quality Points = Credit Hours × Grade Point.
Example: an A (4.0) in a 4-credit course = 16 quality points.
GPA = Total Quality Points ÷ Total Credit Hours, summed across every course this semester.
Cumulative GPA = (Previous GPA × Previous Credits + This Semester's Quality Points) ÷ (Previous Credits + This Semester's Credits).
