How to Calculate High School GPA?

To calculate high school GPA, we need to multiply credit hours by grade points and then sum up all the values. After that, divide the resultant value by the sum of credit hours. For a better understanding, read the following formula.

GPA =  
c1×g1 + c2×g2 + c3×g3 + ...
c1 + c2 + c3 + ...

c = Credit Hours
g = Grade points

Note: Make sure to convert the letter grade into its numerical grade point based on your school grading scale. Our high school GPA calculator uses the most common grading scale that all schools used in the United States.

Now let's take an example.


Suppose, an individual received the following grades in a school exam. Calculate the GPA based on the values.

  • A in math course worth 3 credits (Course type: Regular)
  • A- in history course worth 1 credit (Course type: Honors)
  • B+ in science course worth 4 credits (Course type: AP)
  • B in English course worth 2.5 credits (Course type: Regular)

Firstly, we will convert the letter grade into its numerical grade form based on the weight or course type. Remember that, the numerical values are different for each course type.

  • A = 4 (for Regular)
  • A- = 4.17 (for Honors)
  • B+ = 4.33 (for AP)
  • B = 3 (for Regular)

Now we have grade points and credit values. So, the next step is to place all the values into the GPA formula.

GPA = (3×4) + (1×4.17) + (4×4.33) + (2.5×3) / (3 + 1 + 4 + 2.5)

= 12 + 4.17 + 17.32 + 7.5 / 10.5

= 40.99 / 10.5

= 3.90

As we can see, the manual calculation is complex and we need to find the grade points for each grade using the GPA scale table. So, it's better to use our high school GPA calculator to get rid of all of these things.
