GPA Calculator

Calculate your GPA on the standard 4.0 scale from your grades and course credits. Three courses — an A in a 3-credit class, a B+ in a 4-credit class, and an A- in a 3-credit class — work out to a 3.63 GPA, weighted by credit hours.

Why use GPA Calculator?

GPA is a credit-weighted average, not a simple average of letter grades — a common source of confusion when students try to calculate it by hand. A 3-credit A carries more weight than a 1-credit A, so the correct formula multiplies each course's grade points by its credit hours before dividing by the total credits. This calculator uses the standard unweighted 4.0 scale, the most widely used system across U.S. high schools and colleges. If your school uses a weighted scale for honors or AP courses, or a different point value for plus/minus grades, treat this as a close reference and confirm against your official transcript for anything that needs to be exact — scholarship applications, transfer credit, or grad-school requirements.

Frequently asked questions

How is GPA calculated?

Each letter grade is worth a fixed number of quality points on the 4.0 scale (A=4.0, A-=3.7, B+=3.3, B=3.0, and so on down to F=0.0). Multiply each course's points by its credit hours, add them up, then divide by total credits. A 3-credit A, 4-credit B+, and 3-credit A- gives (4.0×3 + 3.3×4 + 3.7×3) ÷ 10 = 3.63.

Does this match my school's exact GPA scale?

It uses the most common unweighted 4.0 scale. Some schools use a weighted scale (extra points for AP/honors courses) or a slightly different point value for plus/minus grades — check your registrar's official policy if you need an exact match for transcripts or applications.

How do I calculate cumulative GPA across semesters?

Add every course from every semester into the calculator at once — the credit-weighted formula naturally produces your cumulative GPA. There's no need to average semester GPAs together, since that would ignore differing credit loads.

What GPA is a 3.5?

A 3.5 GPA sits between a B+ (3.3) and an A- (3.7) average — generally considered a strong, competitive GPA for most college admissions and many scholarship requirements.
