What does GPA mean?
GPA stands for grade point average. It is a single number that sums up your grades across all your classes, on a scale that usually runs from 0.0 to 4.0 in the United States. Each letter grade is worth a set number of points (A is 4.0, B is 3.0, and so on), and your GPA is the average of those points across every course you take.

In more detail
GPA is the standard way US schools and universities report academic performance. Instead of listing every grade, they convert each one to points and average them, so a 3.5 GPA tells an admissions officer or employer roughly how you have done overall. A higher number is better, and 4.0 is the top of the standard scale, meaning straight A grades.
There are two common versions. An unweighted GPA treats every class the same, so an A is 4.0 whether it was an easy elective or a hard honors course. A weighted GPA adds extra points for harder classes, often +0.5 for honors and +1.0 for Advanced Placement or IB. That is why some students report a GPA above 4.0. Your cumulative GPA is the average across all terms, not just one.
Most US colleges use a weighted average based on credits. A 4-credit course counts more toward your GPA than a 1-credit course. To get the number, each course's grade points are multiplied by its credits, those are added up, and the total is divided by the total credits. The result is your cumulative GPA.
If you have studied under a different system, GPA can feel unfamiliar. The German 1 to 6 Notensystem runs the other way, where 1.0 is the best grade. The Spanish 0 to 10 scale puts 10 at the top. GPA flips that intuition: bigger is better, and 4.0 is the ceiling on the standard scale.
US letter grade to GPA to percentage (standard 4.0 scale)
| Letter grade | GPA points | Typical percentage |
|---|---|---|
| A | 4.0 | 93 to 100% |
| A- | 3.7 | 90 to 92% |
| B+ | 3.3 | 87 to 89% |
| B | 3.0 | 83 to 86% |
| B- | 2.7 | 80 to 82% |
| C+ | 2.3 | 77 to 79% |
| C | 2.0 | 73 to 76% |
| C- | 1.7 | 70 to 72% |
| D | 1.0 | 60 to 69% |
| F | 0.0 | Below 60% |
Step by step
- 1
List every course and the letter grade you earned in each one.
- 2
Convert each letter grade to GPA points using the 4.0 scale (A is 4.0, B is 3.0, C is 2.0, D is 1.0, F is 0.0).
- 3
If your courses have different credit values, multiply each grade's points by that course's credits. If they are equal, you can skip this step.
- 4
Add up all the points (or all the credit-weighted points).
- 5
Divide by the number of courses (or by the total number of credits) to get your GPA.
- 6
For a weighted GPA, add the bonus for harder classes before averaging, often +0.5 for honors and +1.0 for AP or IB.

More questions
Is a 3.0 GPA good?
A 3.0 GPA on the standard 4.0 scale means a B average, which is solid and meets the entry bar for many colleges and programs. Whether it counts as good depends on your goal. Competitive universities and scholarships often look for 3.5 and above, while plenty of programs accept 3.0 or lower. It is a respectable, middle-of-the-road result that leaves room to improve.
What is the difference between weighted and unweighted GPA?
An unweighted GPA caps at 4.0 and treats every class the same, so an A is 4.0 in any course. A weighted GPA gives extra points for harder classes, usually +0.5 for honors and +1.0 for AP or IB, so it can rise above 4.0. Weighted GPA rewards taking a tougher course load. Schools state which version they use, so check before comparing.
How is GPA different from a percentage or the German grade system?
A percentage is your raw score on a single piece of work. GPA is an average across many courses on a fixed point scale, usually 0.0 to 4.0. It is not the same as the German 1 to 6 system, where 1 is best and a higher number is worse, so a US 4.0 is roughly a German 1.0. When applying abroad, schools often convert your grades, so always ask which scale they expect.
