GPA Calculator — Weighted & Unweighted (4.0 / 4.33) + Cumulative

How this calculator works

Want a quick, accurate GPA without juggling grade points by hand? This calculator helps you estimate your grade point average using common 4.0 and 4.33 scales, with options for weighted courses like Honors, AP, or IB. It is designed for students, parents, and educators who want a clear picture of academic performance in a few steps.

What GPA means: your GPA is a weighted average of your course grades, where each grade is converted to a numeric point value and multiplied by the course credit. The total grade points are then divided by the total credits. This makes a one-credit elective count less than a four-credit core class, which is why credit hours matter.

Unweighted vs. weighted: an unweighted GPA uses the base scale (4.0 or 4.33) for every class. A weighted GPA adds bonus points for advanced coursework, which can raise your average above 4.0. In this calculator, Honors adds +0.5 and AP/IB adds +1.0, and each course can be capped by the Max Weighted Cap (default 5.0) to match typical school policies.

How to use the calculator:

1. Select your grading scale (4.0 or 4.33).
2. Add each course with its letter grade and credit value.
3. Mark courses as Honors or AP/IB if applicable.
4. Set a weighted cap if your school uses one.
5. Click Calculate to see your weighted and unweighted GPA.

Real-world uses: estimate semester GPA, track cumulative progress, and preview how a new grade might affect your average. It is also helpful when comparing transcripts, setting academic goals, or filling out scholarship and college applications that ask for GPA.
