What is the GPA Calculator?
Our GPA Calculator is a free, easy-to-use utility that helps high school and college students track their academic progress. It uses the standard 4.0 grading scale to determine your Grade Point Average based on the letter grades you received and the credit hours for each class.
How to Calculate Your GPA
- Add your courses: Enter the name of your class (optional).
- Select your grade: Choose the letter grade you expect or received in the class (A+, A, A-, B+, etc.).
- Enter the credits: Input the number of credit hours the class is worth (usually 3 or 4 for college courses, or 1 for high school).
- Add more rows: Click "+ Add Another Course" if you took more than 4 classes.
- View your GPA: The calculator instantly updates your semester GPA at the top of the tool as you enter your information.
A Walk-Through With Real Numbers
Imagine a college student who took five classes one semester: Calculus II (4 credits, B+), English Literature (3 credits, A), General Chemistry (4 credits, B), Introduction to Sociology (3 credits, A-), and Public Speaking (1 credit, A). Plug those into the calculator and the math runs like this: 4 × 3.3 + 3 × 4.0 + 4 × 3.0 + 3 × 3.7 + 1 × 4.0 = 13.2 + 12.0 + 12.0 + 11.1 + 4.0 = 52.3 grade points across 15 credits. Divide and you land on a 3.49 semester GPA — comfortably in honors range. Switching the Chemistry grade from a B to a B- (3.0 → 2.7) drops the cumulative by 0.08 points; switching it to a C+ (2.3) drops it by 0.19. That's the kind of "what if I bomb the final?" question this tool answers in seconds.
Semester GPA vs. Cumulative GPA
The number this tool produces is your semester GPA — the average for the courses you entered. Your cumulative GPA is the running average across every course you've ever taken. To estimate your new cumulative GPA after this term, multiply your previous cumulative GPA by total prior credits, add this semester's grade points, then divide by total credits including this term. For example, a 3.20 cumulative across 60 prior credits plus a 3.49 semester across 15 new credits works out to (3.20 × 60 + 3.49 × 15) / 75 = 3.26. That's why a single great semester barely moves a long-running cumulative — the prior credits anchor it.
Who is this for?
- College Students: Make sure you are maintaining the GPA required for your scholarship, major, or academic standing.
- High School Students: Track your unweighted GPA for college applications.
Frequently Asked Questions
How is GPA calculated?
GPA is calculated by multiplying the grade point value (e.g., an A = 4.0) by the number of credits for that class. Then, you sum those values for all your classes and divide by the total number of credits taken.
Is this an unweighted or weighted GPA calculator?
This tool calculates an unweighted GPA on a 4.0 scale. Weighted GPAs (often used in high schools for AP or Honors courses) allow for scores higher than a 4.0.
