Add your courses and grades to get your GPA on a 4.0 scale.
GPA (Grade Point Average) converts letter grades into numeric grade points, multiplies each by the credit hours of that course, then divides the total grade points by total credits. This credit-weighting matters because a 4-credit course should count more toward your GPA than a 1-credit course.
GPA acts as a single, comparable snapshot of academic performance across an entire transcript, which is why graduate school admissions, scholarship committees, and some early-career job applications still ask for it even though it can't capture everything about a student's abilities. Because it's credit-weighted, GPA also rewards consistency across a full course load rather than just acing a handful of easy electives — a 3.8 built on mostly 3-4 credit core courses generally reflects differently than the same number built on lighter 1-credit seminars.
Which GPA scale should I choose — 4.0, 4.3, or 4.5?
Most US universities use the 4.0 scale (no A+, or A+ counted the same as A). Some US and Canadian schools use 4.3 (A+ = 4.3). The 4.5 scale is the standard used by many Korean universities. Check your school's official transcript key if you're unsure which one applies to you.
Does this calculator match my official transcript GPA exactly?
It should closely match if your school uses one of the three standard scales included here, but some schools use custom scales, weight honors/AP courses differently, or exclude certain course types (like pass/fail) from GPA. Always confirm against your registrar's official calculation for anything that matters academically.
Can I calculate a semester GPA and a cumulative GPA separately?
Yes — just add the courses for whichever period you want to calculate. To get a cumulative GPA across multiple semesters, add every course from all semesters into the same list at once.
Each letter grade converts to grade points (A = 4.0 down to F = 0.0). GPA = total quality points (grade points × credit hours, summed across courses) ÷ total credit hours. This gives more weight to higher-credit courses, which is how most US colleges compute it.
