Computes your GPA on the standard US 4.0 scale from letter grades, per-course credits, and class type, showing both the unweighted and weighted (Honors +0.5, AP/IB +1.0, capped at 5.0) averages.
GPA calculations are a classic high-school anxiety: each plus/minus counts, credits weight the average, and Honors/AP boost depends on the district's rule. This tool encodes the standard convention and shows both versions at once.

Add a course row for each class
Pick the letter grade (A+ through F), enter credits, and choose Regular / Honors / AP-IB
Check the unweighted and weighted GPAs — weighted uses +0.5 honors, +1.0 AP/IB, capped at 5.0
Remove a course to simulate what-if scenarios
A × 3cr + B+ × 3cr → 3.65 unweighted (4.0 + 3.3 average)Straight A's across 12 credits → 4.0 unweightedAP A + regular A → weighted ≈ 4.5 (5.0-capped course gets the +1 bonus)Q: Is an A+ worth more than 4.0? A: On the standard scale used here, no
A+ and A are both 4.0 unweighted.
Q: How is the weighted GPA computed?
A: Each course gets +0.5 for Honors or +1.0 for AP/IB on top of its letter points, capped at 5.0 per course, then averaged by credits.
Q: Can I compute just one semester? A: Yes
only include that semester's courses.
Q: My school uses a different points table. Is this still useful?
A: The unweighted average is universal; adjust the letter points to your school's table manually.
