GPA Calculator lets you determine how your current term will affect your overall GPA. You can use it before you know your grades to predict your CGPA (Cumulative Grade Point Average). Due to the way this calculator is made, it won't calculate grade replacement if you are repeating a course in college or high school. GPA Calculator will include both failing and new grades. First, you need to enter your total grade points. For example, if you have taken only one term and passed 6 courses with grade B, your total grade points would be 18 (6 courses x 3.0 points). Next, enter number of courses you have taken so far. Using above example, this would equal to 6. Finally, enter how many units each course is worth and type in your expected grades. Click on "Calculate" and you will get your overall CGPA.
