College GPA Calculator
Add each course with its letter grade and credit hours. Credits are weighted properly, so a 4-credit course counts more than a 1-credit one — which is where most quick mental math goes wrong.

Your GPA
3.54
46.0 quality points across 13 credit hours.
The formula
Every course earns quality points: its grade on the 4.0 scale multiplied by its credit hours. Your GPA is the total quality points divided by the total credit hours.
GPA = Σ(grade points × credits) ÷ Σ(credits)
An A in a 1-credit lab and an A in a 4-credit seminar are not the same event. The seminar is worth four times as much, which is why averaging your letter grades gives an answer that can be a tenth of a point off in either direction.
Projecting your cumulative GPA
To see where this semester leaves your overall record, add one extra row for everything you have already taken: put your total credits earned in the credits field, and pick the letter closest to your current cumulative GPA. Then add this semester's courses underneath.
The result is the honest version of a question most students guess at — and it is usually more stubborn than expected. Once you are 60 credits deep, a single strong semester moves the cumulative number far less than it feels like it should.
The 4.0 scale used here
A 4.0, A− 3.7, B+ 3.3, B 3.0, B− 2.7, C+ 2.3, C 2.0, C− 1.7, D+ 1.3, D 1.0, D− 0.7, F 0.0. This is the standard US scale. Schools that award 4.3 for an A+ are the exception; check your registrar if yours is one of them.
Common questions
How is GPA calculated?
Convert each course grade to points on the 4.0 scale, multiply by that course's credit hours to get quality points, add all the quality points together, then divide by the total credit hours. Credits are the whole reason a 4-credit course moves your GPA twice as much as a 2-credit one.
What is the difference between semester and cumulative GPA?
Semester GPA covers one term's courses only. Cumulative GPA covers everything you have taken. To project a cumulative GPA, add a row for your record so far — total credits earned as the credit hours, and your current cumulative GPA as the grade — then add this semester's courses alongside it.
Does an A+ count as a 4.3?
At most universities, no — A+ and A both count as 4.0, and this calculator follows that. A minority of schools award 4.3 for an A+. Check your registrar's grading policy, because it is the one place where two schools' GPAs are genuinely not comparable.
Do pass/fail courses count toward GPA?
Usually not. A passing grade in a pass/fail course earns credit but no quality points, so it is left out of the GPA calculation entirely. A failing grade sometimes does count. Leave pass/fail courses out here unless your registrar says otherwise.
