GPA Calculator — Calculate Your Grade Point Average Free
This GPA calculator computes your grade point average instantly from letter grades and credit hours. It’s for students who want to understand where they stand after quizzes, midterms, or the end of a grading period, and for teachers and parents who need a clear way to verify GPA math. You can use it for semester check-ins, scholarship planning, and goal setting when you want to estimate how different grades affect your overall standing.
To use it, enter each course, choose the letter grade you earned, and enter the credit hours. The calculator converts letter grades into grade points, multiplies grade points by credit hours to produce quality points, then divides total quality points by total credit hours. That’s why a higher-credit class has more impact on your GPA than a smaller-credit elective.
Example: if you earn an A (4.0) in a 3-credit class, that gives 12 quality points. If you earn a B+ (3.3) in a 3-credit class, that gives 9.9 quality points. If you earn an A- (3.7) in a 4-credit class, that gives 14.8 quality points. Total quality points = 36.7 and total credits = 10, so GPA = 36.7 ÷ 10 = 3.67.
Quick Answer:
GPA = total quality points (grade points × credit hours per course) ÷ total credit hours. A = 4.0, B = 3.0, etc. Add your courses and the calculator gives your semester or cumulative GPA instantly.

How to Use This Calculator
- Add your courses. Enter each course name and select the letter grade you earned.
- Enter credit hours. Add the credit hours for each course so the GPA is weighted correctly.
- Review your quality points. Confirm that the letter-grade points and credit hours match your grading scale.
- Check your GPA. Your GPA and total credits update automatically as you change inputs.
- Update after new grades. Re-run the calculation when you receive new grades to track improvement over time.
How it works
GPA is a weighted average based on credit hours. For each course, the calculator converts your letter grade into grade points, multiplies grade points by credit hours to get quality points, and then divides total quality points by total credit hours.
GPA = (Sum of Quality Points) ÷ (Total Credit Hours)
If your school uses plus/minus grades or a weighted scale for honors/AP/IB, make sure your grade-to-point mapping matches what your school reports so your GPA estimate is accurate.
Frequently Asked Questions
How is GPA calculated?
GPA is typically calculated by converting each letter grade into a numeric grade point value (for example, A = 4.0 on a 4.0 scale). Then you multiply each course’s grade points by its credit hours to get quality points, sum total quality points, and divide by total credit hours.
What is a 4.0 GPA scale?
A 4.0 scale is a standard unweighted GPA scale where letter grades map to numeric points. For example, an A is typically 4.0, a B is around 3.0, a C around 2.0, a D around 1.0, and an F is 0.0. Many schools also use plus/minus variations.
What GPA do I need for college?
There is no single universal “required GPA” because colleges consider many factors. But most admissions pages publish minimums or typical ranges. A practical approach is to check the GPA expectations for your target schools and then use this calculator to set a realistic goal based on your remaining classes.
How do I raise my GPA?
To raise your GPA, improve grades in higher-credit courses first because they affect your GPA more. Watch for missing assignments, ask about extra credit, and consider course retakes only if your school’s policy replaces or adjusts grades.
What is the difference between weighted and unweighted GPA?
Unweighted GPA treats classes similarly and uses a 4.0 scale. Weighted GPA adds extra points for advanced coursework like honors, AP, or IB, so grades can land higher (often on a 5.0+ scale). Colleges may also review weighted and unweighted GPA differently, so it helps to know what your school reports.
