High School GPA Calculator

Enter each course with its grade, credits (or units), and level. Supports unweighted (4.0) and weighted (Honors +0.5, AP/IB +1.0; capped at 5.0). You can also drag & drop or pick a CSV — nothing is uploaded.

Unweighted GPA (4.0): A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D+=1.3, D=1.0, D-=0.7, F=0.0.
Weighted GPA: Add +0.5 for Honors and +1.0 for AP/IB per course; cap per-course points at 5.0.
Quality points = grade points × credits. GPA = total quality points ÷ total credits.
Percent→Letter (default mapping): 93–100 A, 90–92 A-, 87–89 B+, 83–86 B, 80–82 B-, 77–79 C+, 73–76 C, 70–72 C-, 67–69 D+, 63–66 D, 60–62 D-, <60 F.
Credits: Use your school’s units (e.g., 1.0 full year, 0.5 semester). This tool weights by credits.
Rounding: Choose 0/2/3 decimals. Internally, math is done at higher precision then rounded for display.

Edge cases & notes

Letter grades are case-insensitive; spaces are ignored. Percent grades use the mapping above.
If a line has invalid/missing fields, it’s skipped with a warning in the console (keeps UI clean).
Weighted bumps never push a course above 5.0 (cap). Unweighted is capped at 4.0 by definition.
CSV stays in your browser; nothing is uploaded to any server.
