Most likely, during high school you've taken a mix of classes: some honors, some standard, and some APs. The weighted GPA reflects that those classes have different difficulty levels. So what's the easiest way to figure out what your weighted GPA is? We have two great methods to calculate it!
What Is a Weighted GPA?
Your GPA, or grade point average, is a way for colleges to quickly see a solid, summary indicator of your intelligence, work ethic, willingness to challenge yourself, and skills.
A weighted GPA showcases the hard work and challenge of your high school career by reflecting whether the classes you took were standard level, honors level, or AP/IB level. It does this by adding .5 to every honors class GPA conversion decimal and adding 1 to every AP class conversion decimal, creating a scale that goes from 0.0 to 5.0.
So, for example, imagine Diane gets an A in AP French and Sven gets an A in standard level Geography. A weighted GPA would recognize that the AP class was most likely harder, so Diane’s A would become 5.0, while Sven's A would be 4.0.
Here is a table that explains how all this usually works in more detail:
Letter Grade | Percentage | Standard GPA | Honors GPA | AP/IB GPA |
A+ | 97-100 | 4.0 | 4.5 | 5.0 |
A | 93-96 | 4.0 | 4.5 | 5.0 |
A- | 90-92 | 3.7 | 4.2 | 4.7 |
B+ | 87-89 | 3.3 | 3.8 | 4.3 |
B | 83-86 | 3.0 | 3.5 | 4.0 |
B- | 80-82 | 2.7 | 3.2 | 3.7 |
C+ | 77-79 | 2.3 | 2.8 | 3.3 |
C | 73-76 | 2.0 | 2.5 | 3.0 |
C- | 70-72 | 1.7 | 2.2 | 2.7 |
D+ | 67-69 | 1.3 | 1.8 | 2.3 |
D | 65-66 | 1.0 | 1.5 | 2.0 |
F | Below 65 | 0.0 | 0.0 | 0.0 |
How Do You Calculate Your Weighted GPA?
There are two different ways to calculate your weighted GPA.
Class-by-class method
This method goes through each of the classes that you've taken, one by one:
#1: First, convert all the final class grades you’ve gotten, keeping careful track of whether the course was honors level, AP level, or standard.
#2: Next, add up all of these converted decimals – this is your sum.
#3: Then, count the total number of classes you have taken.
#4: Finally, divide the sum by the number of classes and round to the nearest tenth—this is your weighted GPA.
Pro tip: you can't simply add each individual year's GPAs together and divide by 4 because you may have taken a different number of classes each year.
Sorted-classes shortcut method
If you've already done an unweighted GPA calculation, then this method is for you:
#1: First, count separately the number of standard classes, honors classes, and AP classes that you've taken.
#2: Next, add your unweighted converted grade sum + (.5 * number of honors classes) + number of AP classes. This is your weighted sum.
#3: Finally, divide the weighted sum by the total number of classes you've taken.
Step-by-Step Example Calculation
Let's go through an example of how this works in practice by calculating the weighted GPA of spymaster alias Jane Doe. We will be calculating the GPA Jane submits on her college applications, so we will leave off her senior year grades.
Note that on her transcript, classes marked with a “+” are honors classes, and those marked with an “a” are AP classes.
First let’s convert her grades. I will convert them into weighted and unweighted format so you can see the difference:
9th grade | 10th grade | 11th grade | ||||
Unweight. | Weight. | Unweight. | Weight. | Unweight. | Weight. | |
3.0 | 4.0 | 3.3 | 3.8 | 3.3 | 4.3 | |
3.7 | 3.7 | 4.0 | 4.0 | 4.0 | 4.0 | |
4.0 | 4.0 | 3.0 | 3.0 | 3.3 | 3.8 | |
3.0 | 3.0 | 3.3 | 3.8 | 4.0 | 5.0 | |
3.3 | 3.8 | 3.7 | 4.7 | 4.0 | 5.0 | |
Total | 17.0 | 18.5 | 17.3 | 19.3 | 18.6 | 22.1 |
Honors classes | 2 | 2 | 1 | |||
AP classes | 0 | 1 | 3 | |||
Total number of classes | 6 | 6 | 6 |
Boy, Jane really stepped up her game junior year! Nicely done.
Class-by-class method:
Sum of weighted scores = 59.4
Number of classes taken = 15
Jane's weighted GPA = 59.4 / 15 = 4.0
Sorted-classes method:
Sum of unweighted scores = 52.9
Number of honors classes = 5
Number of AP classes = 4
Number of classes taken = 15
Weighted sum = 52.9 + (.5 * 5) + 4 = 59.4
Jane's weighted GPA = 59.4 / 15 = 4.0
