How to Calculate GPA Manually
Calculating your GPA involves converting your letter grades to grade points, multiplying them by the number of credits for each course, and then finding the average. Here is a step-by-step guide. For more detail, read our full article on how to calculate your GPA.
Step 1: Convert Letter Grades to Grade Points
First, assign a numerical value (grade point) to each letter grade based on the standard 4.0 scale.
| Letter Grade | Grade Point (4.0 Scale) |
|---|---|
| A | 4.0 |
| A- | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| C | 2.0 |
| D | 1.0 |
| F | 0.0 |
Step 2: Calculate Total Quality Points
For each course, multiply the grade point by the number of credits (or credit hours). The result is the “quality points” for that course.
Formula: Grade Points × Course Credits = Quality Points
Step 3: Calculate Your GPA
Sum the total quality points from all your courses and divide by the total number of credits you took.
GPA Formula: (Total Quality Points) / (Total Credit Hours)
Weighted vs. Unweighted GPA
It’s crucial to understand the difference between weighted and unweighted GPAs, as our calculator can handle both. Unweighted GPA is on a strict 4.0 scale, while weighted GPA gives extra “weight” to more challenging courses like AP, IB, or Honors. This means a student can achieve a GPA above 4.0. Learn more in our guide to weighted vs. unweighted GPA.
Frequently Asked Questions (FAQ)
What is considered a good GPA?
A “good” GPA is subjective and depends on your goals. For competitive colleges, a GPA of 3.5 or higher is often expected. For scholarships or specific programs, requirements may be even higher. Nationally, the average high school GPA is around 3.0. We have a full article discussing what a good GPA is.
How do I calculate my cumulative GPA?
To calculate your cumulative GPA, you need your previous GPA and the total credits you’ve already taken. Our calculator does this automatically if you fill in the optional fields. The manual formula combines your previous total quality points with your new semester’s quality points and divides by the new total of all credits taken.
Does this GPA calculator work for college and high school?
Yes! The GPA calculation process is the same for both high school and college. The main difference is that high schools more commonly use weighted GPAs to reward students for taking advanced placement (AP) or honors classes.
