About this calculator
GPA is credit-weighted average of grade points (4.0 = A, 3.0 = B, etc.). New cumulative = (old cum × old credits + new GPA × new credits) / total. As credit total grows, individual semester impact shrinks — a 4.0 semester at 60 credits in barely moves a 3.4 cum, while at 15 credits in same semester moves it noticeably more (small base).
Frequently asked
GPA scale?+
US 4.0 standard: A=4.0, B=3.0, C=2.0, D=1.0, F=0. Some schools use +/− adjustments (B+ = 3.3).
Quality points?+
Course grade × credits. 3 credits at A (4.0) = 12 quality points. Sum across semester / total credits = GPA.
Why does change shrink?+
Semester is fraction of total credits. 15 of 75 = 20% weight. 15 of 150 = 10% weight.
Can a high semester offset low cum?+
Yes but slowly. To move from 3.0 to 3.5 with 60 credits done: need 4.0 over next 60 credits.
Major-only GPA different?+
Yes — major GPA only counts major-required courses. Calculated separately. Use this for cumulative.
