What is GPA?
GPA stands for Grade Point Average and it's one of the measures of students' achievements and academic performance. The calculation is done by converting the grades to a numerical scale and averaging them, according to given credits (weights). GPA may be calculated on the basis of grades from one semester, a year, or even your whole academic career.
Although GPA is a basic estimator and may vary a bit between schools, it's a measure often used by academic institutions and potential employees. It finds application in assessing and comparing students and creating the rankings for:
 scholarship awards, meritbased financial aid, funding programs;
 graduation honors and awards;
 job interviews and admission decisions.
College GPA scale (4.0 GPA scale)
Most schools in the US use a socalled 4.0 GPA scale  a 4 point grading scale. The table below shows a typical letter grade/GPA conversion system:
Letter Grade  Percentile  4.0 scale  +4.0 scale 

A+  97100  4  4.3 
A  9396  4  4 
A  9092  3.7  3.7 
B+  8789  3.3  3.3 
B  8386  3  3 
B  8082  2.7  2.7 
C+  7779  2.3  2.3 
C  7376  2  2 
C  7072  1.7  1.7 
D+  6769  1.3  1.3 
D  6566  1  1 
F  Below 65  0  0 
Some schools give 4.3 score for A+ grade, so in that case, it's possible to obtain the final score exceeding the standard maximum 4.0 GPA. Although the values in the table are the ones most often used by academic institutions, the percentage intervals and the college GPA scale may differ between schools, so check out your school rules and statute.
How to calculate college GPA? College GPA formula
You've already found out what is GPA, so the time has come for some maths. A general formula for calculation of college GPA is:
GPA = Σ (grade value × credit points) / Σ credit points
So, simply speaking, it's a ratio of sum of weighted grades divided by all credit points. It's not a difficult task to find a GPA value yourself! The most demanding part is the calculation of weighted average of your courses. Let's have a look at the exemplary calculation:
Assume we want to find GPA of our four courses, with different credit points.
Course  Credits  Grade 

Maths  3  A 
Physics  4  B+ 
Biology  2  C 
Chemistry  2  B 
How to calculate college GPA manually?
 First, convert letter scores into numbers. Use the table from the previous paragraph.
Course  Credits  Grade  Scale 

Maths  3  A  4.0 
Physics  4  B+  3.3 
Biology  2  C  2.0 
Chemistry  2  B  2.7 
 Then, sum up all multiplications of the course grade and respective credits
3 * 4.0 + 4 * 3.3 + 2 * 2.0 + 2 * 2.7 = 34.6
 Divide the result by the sum of all credits and round to 3 significant figures:
34.6 / (4 + 3 + 2 + 2) = 3.145145145... ≈ 3.15
How to calculate it faster? Use our college GPA calculator!

Select your grade for the first course. So it's 'A' for our first exemplary classes  Maths.

Enter the class credits. Change the default value from 1 to 3.

Repeat until all courses from the list are included. It's ok if you want to enter less than five courses  the calculator will ignore the blank boxes.
For our case, we'll select:
 Course #2 (Physics) grade as B+, with respective credits: 4
 Course #3 (Biology) grade as C and type the credits: 2
 Course #4 (Chemistry) grade: B and respective credits: 2

Here you go! The college GPA calculator did all the maths, and the GPA value is displayed.
If you don't have the credits for courses, leave the default value 1  every course will be equally important, and not the weighted average, but standard arithmetic average will be used.
Use our tool as a college cumulative GPA calculator
With this calculator, you can also calculate your cumulative GPA. Just hit the Advanced mode
button below the tool, and two boxes will appear  for your current GPA score and sum of credits you got.
Coming back to the example from a previous paragraph: assume that we've just calculated the scores from the second semester, and we'd like to know what's the cumulative GPA after whole freshmen year.
 Assume that we finished first semester with GPA = 3.3. Type that value into
Cumulative GPA
box.  During the first semester, we did courses for 16 credits. Enter 16 into
Credits
.  Under the calculator you'll find the GPA (3.15) and also cumulative GPA, which is equal to 3.24 in our example.
Average college GPA
It's hard to pick one single number to estimate average college GPA. The grades are rising through the years (check out the great charts on grade inflation website), there are differences among schools, fields of study, gender, ethnicity, place of studying, to name only a few factors. If  after that introduction  you still want to see one number, here it is  average college GPA is around 3.15: 3.0 for public schools and 3.3 for private colleges and universities according to 2010 studies. A is now the most common grade in all types of colleges, and it's obtained more and more often. Grade point averages have increased around 0.1 points every ten years  in the 1950s, an average GPA was 2.52.
You need to remember that the average college GPA depends a lot on the major: science majors tend to have lower GPAs than humanities majors (e.g., 2.78 and 2.90 are the average GPAs in Chemistry and Maths, respectively; whereas Education has a GPA equal to 3.36). Another critical factor is the school you're attending  highly selective colleges like Harvard or Stanford have higher average undergraduate GPAs than schools with high acceptance rate. You can read more about average college GPA topic on the Prep scholar website.
What is a good GPA in college?
Well, the answer for such question is quite obvious  it really depends. On your ambition, the college you're attending, your major and many other factors.
Generally speaking, 3.0 GPA is a "B" mark  which stands for average. Many times it's the lowest score you can get to continue specific majors or courses. 3.5 GPA is often seemed as the above average, good or even very good result, but  as we said before  it may vary for your major and school.
If your GPA is not as high as you would like it to be  don't worry so much, as a GPA score is relatively low on the employers' list. More important factors are internships and work experience, your major, volunteering, or even extracurricular activity.
