⭐ Starlight Tools / GPA Calculator

Calculate unweighted & weighted GPA, cumulative GPA, and the grades you need to reach a target GPA.

How this calculator works

Unweighted GPA uses your base scale (4.0 or 4.33). Weighted GPA adds per-course bonuses (Honors +0.5, AP/IB +1.0) and caps each course by the Max Weighted Cap (default 5.0). GPA = Σ(grade points × credits) ÷ Σ(credits).
