How to Calculate a Semester GPA
A **GPA calculator for semester grades** is an essential tool for students. It works by taking the grade and credit hours for each course and calculating a weighted average. The key is converting your letter or percentage grades into grade points on the **4.0 GPA scale**.
The formula is: Semester GPA = Σ (Grade Point × Credits) ÷ Σ Credits
For example, if you took three classes with the following grades and credits: A (4.0) x 3 credits, B+ (3.3) x 4 credits, and C (2.0) x 3 credits, the calculation would be:
(4.0 × 3) + (3.3 × 4) + (2.0 × 3) = 12 + 13.2 + 6 = 31.2
Then you divide by the total credits: 31.2 ÷ (3+4+3) = 31.2 ÷ 10 = 3.12. Your Semester GPA is 3.12.
What is a 4.0 GPA Scale & Common Grade Mappings
The **4.0 GPA scale** is the standard for most U.S. schools, with an A being the highest grade at 4.0. Grades with a plus or minus (e.g., A-, B+) adjust the grade point slightly.

| 83-86 | B | 3.0 |
| 80-82 | B- | 2.7 |
| 77-79 | C+ | 2.3 |
| 73-76 | C | 2.0 |
| 70-72 | C- | 1.7 |
| 67-69 | D+ | 1.3 |
| 65-66 | D | 1.0 |
| < 65 | F | 0.0 |
How to Calculate Your Cumulative GPA Across Semesters
To compute your **cumulative GPA**, you must include all your academic data from previous semesters. This is a weighted average of your previous GPA and the GPA of your current semester. This is useful for those who want to use a **final GPA calculator** to determine their overall average.
The formula for cumulative GPA is:
Cumulative GPA = (Previous GPA × Previous Credits + Semester Quality Points) ÷ (Previous Credits + Semester Credits)
Final GPA Calculator — What Grade Do You Need?
Our **final GPA calculator** can help you figure out what you need to achieve your target GPA. This "what-if" scenario is crucial for planning your semester to get the grades you want. By entering your current data and your goal, the tool will solve for the grade point average you need in your upcoming classes.
Final Grade Needed Formula: Required Quality Points = (Target GPA × Total Credits) - (Current Quality Points)
To find the needed GPA, you would then divide the Required Quality Points by the credits for your upcoming courses.
Frequently Asked Questions
What is a GPA?
GPA (Grade Point Average) is a numerical summary of your academic performance. It is a weighted average of your course grades, where the weights are the number of credit hours for each course.
What is the difference between weighted vs. unweighted GPA?
An unweighted GPA treats all courses equally on a 4.0 scale. A weighted GPA gives extra points (e.g., 4.5 or 5.0) for advanced courses like honors, AP, or IB, reflecting their increased difficulty.
How is GPA rounding done?
Most universities round to two decimal places (e.g., 3.67), but it's important to check your school's specific policy on rounding rules.
How do I find out my quality points?
Quality points are the sum of all your grade points multiplied by the credit hours for each class.
