About GPA Calculator
GPA Calculator computes your grade point average on the standard US 4.0 scale from your course grades and credit hours. It is the back-of-envelope tool for checking the impact of a difficult class on your overall GPA, predicting the grade you need on a final to hit a target average, or simply seeing where you stand mid-semester before official transcripts post.
Worked example: add three courses — A in a 3-credit class (4.0 × 3 = 12 grade points), B+ in a 4-credit class (3.3 × 4 = 13.2), and C in a 3-credit class (2.0 × 3 = 6.0). Total grade points = 31.2, total credits = 10, weighted GPA = 3.12. The calculator lets you add a row per course and updates the GPA live as you change grades, credits, or course count.
Two notes on scales. The mapping used is the standard US 4.0 scale (A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, …, F = 0.0). Some institutions use slight variations — A+ counting above 4.0, plus/minus weighted by 0.3 instead of 0.33, weighted high-school scales that go to 5.0 for AP/IB classes — so the exact figure your school reports may differ slightly. The calculator gives you the unweighted standard-scale figure, which is what most US colleges use for admission and graduation calculations.
