GPA Calculator
Turn your letter grades and credit hours into a grade point average — and a cumulative GPA across terms.
Credit-weighted
Courses with more credits count for more, just like on an official transcript.
Scales differ
This uses the standard US unweighted 4.0 scale; some schools weight honors and AP courses higher.
What is a GPA?
Your grades on a single number line
A grade point average (GPA) condenses all your course grades into one number on a 0–4.0 scale. Each letter grade is worth a set number of grade points — an A is 4.0, a B is 3.0, and so on — and each course is weighted by its credit hours. According to most US institutions, the GPA is the headline figure on a transcript and the number that scholarships, honor rolls, and graduate programs look at first. This calculator computes it for a term and, if you add your prior record, your cumulative GPA across your whole studies.
GPA is the credit-weighted average of your grade points: multiply each course's grade points by its credits, add those up, and divide by total credits.
GPA = Σ(grade points × credits) / Σ creditsThe grade points come from the standard 4.0 scale: A+ and A are 4.0, A- is 3.7, B+ is 3.3, B is 3.0, B- is 2.7, and so on down to F at 0.0. Each course's grade points are multiplied by its credit hours to give "quality points", and the GPA is total quality points divided by total credits. Because of the credit weighting, an A in a four-credit course moves your GPA more than an A in a one-credit course.
Say you took four courses: an A (3 credits), a B+ (4 credits), an A- (3 credits), and a B (3 credits).
Convert grades to points
A = 4.0, B+ = 3.3, A- = 3.7, B = 3.0.Weight by credits
4.0×3 + 3.3×4 + 3.7×3 + 3.0×3 = 12 + 13.2 + 11.1 + 9 = 45.3 quality points.Add up credits
3 + 4 + 3 + 3 = 13 credit hours.Divide
45.3 ÷ 13 = 3.48 GPA.
The calculator gives a term GPA by default, and a cumulative GPA once you add your prior record.
Term GPA
The GPA of just the courses you enter — useful for checking how a single semester went.
Cumulative GPA
Your GPA across every term. Enter your prior GPA and the credits it covers to roll this term in.
Why credits matter
Old credits anchor your cumulative GPA, so a strong new term moves it less once you have many credits behind you.
To combine terms, the calculator weights your prior GPA by your prior credits, adds this term's quality points and credits, and divides. According to academic advising guidance, this is exactly how registrars compute a running cumulative GPA. If you are converting between grading systems, our reverse percentage calculator helps with percentage grades, and our Notenpunkte converter handles the German points scale.
A GPA above 3.0 is generally considered good, above 3.5 strong, and a 4.0 a perfect record on the unweighted scale. The total-credits figure tells you how much coursework went into the number, which matters because a high GPA over many credits is harder to earn than the same GPA over a single course. If you added a prior GPA, the cumulative figure is the one most programs care about, while the term GPA shows how the latest semester compares. Remember that the result depends on the scale: a school that weights honors and AP classes can report a GPA above 4.0, which this unweighted calculator does not model.
The maths is standard; the scale is not universal.
Check your school's scale
This calculator uses the standard US unweighted 4.0 scale and credit-weighted averaging. Many schools differ: some weight honors and AP courses on a 5.0 scale, some use plus/minus differently or not at all, and some count pass/fail or audited courses outside the GPA. International systems use entirely different scales. Treat the result as a close estimate, and check your institution's official grading policy and transcript for the figure that counts toward graduation, honors, and applications.
