Short answer
Weighted GPA adds +0.5 for Honors and +1.0 for AP/IB courses to the base 4.0 letter grade, then averages by credits.
What is the High School GPA Calculator?
High school GPA on a 4.0 scale, with an optional weighted version that boosts Honors and AP/IB courses to reward rigor.
How does the High School GPA Calculator work?
Convert each letter grade to points, add the boost for Honors or AP/IB, multiply by credits, sum, and divide by total credits.
Formula
Variables
letterPtsA=4.0, A−=3.7, B+=3.3 … F=0typeBoostRegular +0, Honors +0.5, AP/IB +1.0
Explanation
Weighted GPA rewards taking harder classes. A B in an AP class (3.0 + 1.0 = 4.0) equals an A in a regular class.
Examples
Example 1: 5 courses mixed regular / honors / AP
Weighted ≈ 4.10, unweighted ≈ 3.60.
Applications

Limitations
- Not every school uses the +0.5 / +1.0 scheme — some use 5.0 scale, some cap at 4.5
Common mistakes
- Boosting an F grade — most schools do not boost failing grades
Tips
- Ask your counselor which weighting scheme your transcript uses before comparing to peers
