High School GPA Calculator
Weight each entered grade-point value by its matching course credits. Optional honors or AP bonus points are added course by course for the weighted estimate.
How to use this calculator
Enter matching course grade-point values, course credits, and honors or AP bonus points.
Review school grade conversion, plus/minus values, repeated courses, pass/fail treatment, semester weighting, and official transcript policy.
Read unweighted GPA, weighted GPA, and credits included.
Formula
Unweighted GPA = Σ(grade points × credits) ÷ Σcredits. Weighted GPA = Σ((grade points + matching bonus points) × credits) ÷ Σcredits.
Worked example
Four equally weighted courses with grade points 4, 3, 3, and 2 give an unweighted GPA of 12 ÷ 4 = 3.0.
Assumptions and limits
- The user must convert grades and bonuses with the school’s own scale; the calculator does not infer letter-grade, course-level, repeat, or transcript rules.
- High School GPA Calculator treats the entered values as estimates and does not infer missing project, account, or personal details.
- Calculations retain working precision except where the cited method requires an intermediate rounding step; displayed values are then formatted separately. Source rules and dated rates must be rechecked when they change.
