How do you calculate cumulative GPA's?

Answer 1

Cumulative GPA is your complete GPA after all your courses have been figured out.

The following examples on how to calculate cumulative GPA's are based on the following scales.

Regular Scale:

• A = 4.0
• A- = 3.66
• B+ = 3.33
• B = 3.0
• B - = 2.66
• C+ = 2.33
• C = 2.0
• C- = 1.66
• D+ = 1.33
• D = 1.0
• D- = 0.66
• F = 0.00

Honors/Advanced Placement Scale:

• A = 5.0
• A- = 4.66
• B+ = 4.33
• B = 4.0
• B - = 3.66
• C+ = 3.33
• C = 3.0
• C- = 2.66
• D+ = 2.33
• D = 2.0
• D- = 1.66
• F = 1.00

Now using these two scales lets give an example.

Freshmen Year (9th Grade):

1st Semester

English 9 - B+

Algebra 1 - A-

Physical Science - C+

World History - D-

2nd Semester

English 9 - A

Algebra 1 - A-

Physical Science - B+

World History - B-

Now you'd take the value of your letter grades using the GPA scale.

Semester 1

3.33 + 3.66 + 2.33 + 0.66 = 9.98.

Semester 2

4.0 + 3.66 + 3.33 + 2.66 = 13.65

Total: 13.65 + 9.98 = 23.63 ÷ 8 grades = 2.95375; So roughly a 3.0 average (B).

You'd complete these steps taking your total (23.63 for 9th Grade) and adding it to your totals for the other grades, dividing by the number of classes at the end.

So If you ended High School with a Total of 80 points and you took 28 classes total during your High School time your cumulative GPA would be 80 ÷ 28 or 2.857 or a 2.9 average.
