Cumulative GPA on the 4.0 scale is what colleges, scholarships, and most state ESA programs use. This calculator handles both letter grades and raw percentages, and applies the standard +1.0 weighted bump to Honors, AP, IB, and dual-enrollment courses.
How the math works
GPA = (sum of grade points × credits) ÷ (sum of credits). Each letter grade converts to a 4.0-scale point value: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, and so on. Percentages convert through the same scale (93+ = A, 90-92 = A-, etc.).
Weighted GPA adds +1.0 to each grade point for courses you mark as Honors / AP / dual enrollment, capped at 5.0 for A grades. Most selective colleges look at both unweighted and weighted — show both on your transcript.
