How to calculate your GPA manually

It is essential you know how to calculate your GPA manually and I’d show you right away.

Step 1: You should know the grade points assigned to every grade you achieved.
Step 2: You should know the credits hours for every specific course you took.
Consider the table below for a Mechanical Engineering student:

Subject or  Course nameCredit HoursLetter GradeGrade Points
Subject / Course 14A4
Subject / Course 25A-3.70
Subject  / Course 33B+3.30
Subject / Course 43B3.00
Subject / Course 52B-2.70
Subject / Course 61C+2.3


The calculation

To calculate the GPA of the student with the result above. You should follow the steps below:

Grade Point Average (GPA) formula=  Total Credit Hours * Total Grade Points
Total Credit Hours

Total Credit Hours * Total grade points = 4 * A (4) +5 * A- (3.70) + 3 * B+ (3.30) + 3 * B (3.00) + 2 * B- (2.70) + 1 * C+(2.3)
= 16 + 18.5 + 9.9 +9 +5.4 +2.3
=61.1 grade points

Can the students GPA be 61.1? Absolutely not.

We need to calculate the total credit hours according to the GPA formula above.

Total credit hours = 4 +5 +3+ 3 +2 +1 = 18 hours.

Therefore, the students GPA (Grade point Average) = 61.1 / 18

= 3.39 ( to 2 decimal places)


As you can see from the table and results, an A in a 4-unit course is stronger than an A in a 1-unit course.
