GPA Calculator

The GPA Calculator spreadsheet should be pretty intuitive, and some instructions are included at the top of the worksheet.

Adding Semesters: You can include additional semesters by simply copying the set of rows for one of the semesters and pasting it at the bottom. The formulas in the spreadsheet are designed specifically for making this process simple.

Inserting Rows: If you need to insert rows to add more classes for a particular semester, then make sure to insert news rows above the last row or below the first row in the semester block. This will help ensure that the references in the summation formulas stretch to include the new row(s). You will also need to copy the formula for the Points when you add the new rows.

GPA stands for Grade Point Average, but most of the time, to calculate GPA requires using a weighted average. For example, if you earned an A in a 3-credit course and a B in a 2-credit course, your GPA is not simply the average of an A and B. Instead, the grades are weighted based on the number of credit hours in the course. That can seem complicated, but it's not really that bad.

Below are the steps you can use to calculate your GPA if you happen to be caught without a computer.

Step 1 - Convert Letter Grades to Points

To the right is a typical 4.0 GPA Scale, showing the grade points and the letter grade equivalent. The first step in calculating your GPA is to convert the letter grades to points.

Step 2 - Multiply the Points by the Number of Credit Hours

If I got an A- in a 3-credit class, the points for that class would be 3.7 times 3 credits equals 11.1 points. (This is where the weighting comes into play)

Step 3 - Add the Total Points then Divide by the Total Credit Hours

To calculate your GPA, add up the total grade points and the total credit hours and then divide the total grade points by the total credit hours. If you include only the points and hours for a single semester, this will calculate your GPA for the semester. If you include all the points and hours for every semester, this will calculate your overall cumulative GPA.
