High School GPA Calculator — Weighted & Unweighted GPA

This high school GPA calculator estimates both your weighted and unweighted GPA based on the letter grades you earn and the type of course you take. It’s designed for students who want to understand where they stand for college planning, and for teachers or parents who want a simple way to verify the math behind GPA estimates.

Weighted GPA gives extra credit for advanced coursework like AP, IB, and Honors classes, while unweighted GPA treats most courses the same on a 4.0-style scale. By entering your courses as regular, honors, AP, or IB, you can see how advanced classes change your GPA estimate. Use it when midterm/final grades are posted, when planning which classes to take next, or when you want to compare “what-if” scenarios.

Example: if you earn an A in an AP class and a B+ in a regular class, your weighted GPA will rise more than your unweighted GPA because the AP course is treated as higher-impact. Update your inputs as you receive grades and the GPA totals will refresh automatically.

Quick Answer:

High school GPA can be weighted (AP/IB/honors get extra points, often 5.0 scale) or unweighted (all courses on 4.0). Add your courses and mark which are advanced; the calculator shows both GPAs for college applications.

How to use this calculator

  1. Add your courses. Choose whether each is regular, honors, or AP/IB.
  2. Enter grades and credits. Enter your letter grade and credits for each course.
  3. See both GPAs. Your weighted and unweighted GPA update automatically.

How it works

High school GPA uses a point mapping for letter grades. Unweighted GPA applies that mapping on a standard 4.0-style scale. Weighted GPA increases the point value for advanced course types like Honors, AP, and IB. This calculator totals your grade points for each course type and uses the appropriate weights so you get both estimates together.

If you don’t know your exact school’s scale, this still provides a close estimate—just make sure your AP/Honors/IB selections match how your school categorizes each class.
