This free online grade point average calculator will help you to track your present GPA as well as set and meet goals for future grading periods (semesters or quarters).
Specifically, this calculator creates individual GPA calculators for any number of grading periods you choose  each of which recalculates as you type the credit hours and select the letter grades for each class.
And unlike most grade point average calculators, this one even allows you to track your major GPA separately from your overall GPA.
Plus, the calculator also includes features for tracking and calculating your cumulative GPA, as well as a builtin feature that tells you how many credits you need at 4.0  and how many you need at your own realistic grade point average  to raise your GPA to a desired level.
And if all that isn't enough, the calculator also includes ...
GPA is an acronym for Grade Point Average, which is used to track your level of success for each grading period (semester or quarter), as well as for tracking your cumulative measure of success over the course of your college education.
Since your GPA is one of the first things potential employers look for in your college transcript, it's extremely important that you work hard to maintain a high GPA. This is especially true in the early days of your college education, because the more credit hours you accumulate at lower grades, the longer it will take to raise your GPA.
In order to calculate your grade point average for one grading period, you first need to understand the key variables that make up the formula.
Credit hours: Each class you take will have a number of credit hours assigned to it, which are usually listed in your school's course catalog. Credit hours per class typically range between 1 and 5.
Quality credit hours: Credit hours earned for classes that are taken for a letter grade versus classes taken on a Pass/NoPass basis.
Quality point multipliers: The number of points awarded for an earned letter grade (A = 4 points, B = 3 points, etc.). The quality point multipliers can vary slightly from school to school, which is why the calculator on this page allows you to edit the default multipliers to match those of your school.
Quality points: The product of the earned quality credit hours multiplied by the letter grade's corresponding quality point multiplier. For example, if you earn an A in a 4credithour class, the quality points earned would be 16 (4 credit hours x multiplier of 4 for an A = 16).
So now that you understand the terms involved, here is the formula for calculating your grade point average:
GPA =  Total quality points earned 
Total quality credit hours earned 
Here is a screen shot from the printer friendly results generated by the calculator on this page:
Notice how the calculated points on each line are the product of the credit hours times the multiplier. The GPA is then figured by adding up the total points and dividing by the total quality credit hours.
Your cumulative grade point average is calculated basically the same way you calculate GPA for a single grading period, except you will be using your total quality points todate and total quality credit hours earned todate.
Cumulative GPA =  Total quality points earned to date 
Total quality credit hours earned to date 
To calculate what you need to do to raise your grade point average from your present average to a desired average, you can use one of two methods: the Straight A Method, or the Realistic Grade Method. I'll present the formulas for each separately.
This method calculates how many future credit hours you need to get straight "A"s (4.0) in to reach your target grade point average. The formula is as follows:
Straight A Credits =  Cum. GPA Credits x (Target GPA  Cum. GPA) 
4.0  Target GPA 
So if your cumulative grade point average is 2.5 after 60 credits, and you want to see how many future straight A credits you need to reach a target of 3.0, here is how you would calculate the needed credits:
Straight A Credits =  60 x (3.0  2.5) 
4.0  3.0  
Straight A Credits =  60 x (.5) 
1.0  
Straight A Credits =  30 
1.0  
Straight A Credits =  30 
So using this method you would need to get straight "A"s in your next 30 quality credit hours in order to raise your grade point average from 2.5 to 3.0.
If getting straight "A"s is beyond your time and/or abilities, this method calculates how many future credit hours you need to get at your personal, highest realistic grade point average in order to reach your target grade point average. The formula is as follows:
Realistic Credits =  Cum. GPA Credits x (Target GPA  Cum. GPA) 
Realistic GPA  Target GPA 
So if your cumulative grade point average is 2.5 after 60 credits, and you believe the highest grade point average you could realistically achieve for future classes would be 3.5, here is how you would calculate how many 3.5 credits you need to reach a target of 3.0:
Realistic Credits =  60 x (3.0  2.5) 
3.5  3.0  
Realistic Credits =  60 x (.5) 
0.5  
Realistic Credits =  30 
0.5  
Realistic Credits =  60 
So in order to raise your grade point average from 2.5 to 3.0 using a realistic future GPA of 3.5, you would need to average 3.5 in your next 60 quality credit hours.
If a portion of your earned credit hours are from a school that used different grading periods than your present school, then in order to calculate your cumulative grade point average you will need to convert the unlike credit hours to match the grading period of your present school.
Even though the calculator on this page has a builtin credit hour conversion tool, I will list the formulas used by the calculator in case you want to convert the hours manually.
Semester Hours = Quarter Hours x 1.5 
Quarter Hours = Semester Hours x .667 
With that, let's use the College GPA Calculator to calculate any combination of your present, cumulative, and target grade point average.
