How is GPA calculated?

Multiply each course's grade points by its credit hours, add them up, and divide by total credit hours. For example, an A (4.0) in a 3-credit class and a B (3.0) in a 4-credit class gives (12 + 12) ÷ 7 ≈ 3.43.

What grade points does each letter grade carry?

On the standard 4.0 scale: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0. Schools using plus/minus grading typically adjust by about 0.3 — for example A− = 3.7 and B+ = 3.3 — though exact values vary by institution.

What's the difference between weighted and unweighted GPA?

Unweighted GPA caps at 4.0 regardless of course difficulty. Weighted GPA awards bonus points for harder classes — commonly +0.5 for honors and +1.0 for AP/IB — so scales run to 4.5 or 5.0. Colleges often recalculate applicants' GPAs with their own method.

How do I calculate a cumulative GPA across semesters?

Don't average the semester GPAs directly — that ignores differing credit loads. Instead total all quality points (grade points × credits) from every semester and divide by all credits attempted. This calculator does that when you enter all courses.

How much can one semester change my GPA?

It depends on how many credits you've accumulated: the more credits behind you, the more inertia your GPA has. A freshman can move their GPA dramatically in one term, while a senior with 100+ credits will see only small shifts even with straight As.

How it works

GPA is a credit-weighted average of your grades. Each letter grade maps to grade points (A = 4.0, B = 3.0, …), and each course's points are weighted by its credit hours — so a 4-credit class counts twice as much as a 2-credit one. You divide the total weighted points by the total credits.

Grade Point Average

GPA = Σ(grade points × credits) ÷ Σ credits

grade points: A=4.0, A−=3.7, B+=3.3, B=3.0, … on a 4.0 scale
credits: credit hours for each course

Worked example

Course 1: A (4.0) worth 3 credits
Course 2: B (3.0) worth 4 credits

Weighted points = (4.0×3) + (3.0×4) = 12 + 12 = 24
Total credits = 3 + 4 = 7

GPA = 24 ÷ 7 ≈ 3.43.

Good to know

Weighting by credits is the whole point — a high grade in a small class moves your GPA far less than the same grade in a big one.
Weighted GPAs add bonus points for honors/AP/IB courses (often a 5.0 scale), which is why some GPAs exceed 4.0.
Cumulative GPA averages every term together; a strong single semester nudges a large cumulative total only slightly.
