Start from the GPA and credits already on your transcript, add the courses you are taking now, and see your new cumulative GPA instantly — along with the semester GPA you would need to reach a target like 3.0 for good standing or 3.5 for honors.
📌 Standard US 4.0 scale (A = 4.0, A− = 3.7, B+ = 3.3 … F = 0). Schools differ on A+ (4.3 at some), on weighting bonuses and on which classes count — your transcript is the official number.

The cumulative GPA formula
new cumulative GPA = (current GPA × credits so far + Σ new grade points × credits) ÷ (credits so far + new credits)
needed semester GPA = (target GPA × total credits − current GPA × credits so far) ÷ new credits
Worked example: 3.42 over 45 credits is 153.9 grade points. This semester: Organic Chemistry B (3.0 × 4 = 12.0), Statistics A− (3.7 × 3 = 11.1), Writing Seminar A (4.0 × 3 = 12.0), Psychology B+ (3.3 × 3 = 9.9) — 45.0 points over 13 credits, a 3.46 semester. New cumulative: 198.9 ÷ 58 = 3.43. Reaching 3.50 this term would have required a 3.78 semester.

Frequently asked questions
Cumulative GPA is total grade points divided by total credits across every term. Your current GPA times credits completed gives the grade points earned so far; add this semester’s points (grade value × credits for each course) and divide by the new credit total. With a 3.42 GPA over 45 credits (153.9 points) and a 13-credit semester at 3.46 (45 points), the new cumulative GPA is 198.9 ÷ 58 = 3.43.
Required semester GPA = (target × total credits after this semester − current points) ÷ this semester’s credits. To move from 3.42 with 45 credits to 3.50 after a 13-credit semester: (3.5 × 58 − 153.9) ÷ 13 = 3.78. The calculator shows this as “needed”; if it is above 4.0 the target is not reachable in one term.
Because each new semester is a smaller share of the total. A 4.0 semester of 15 credits lifts a 3.0 GPA to 3.50 after 15 earlier credits, but only to 3.14 after 90 earlier credits. Early terms set the trajectory; late in a degree, even perfect grades shift the cumulative number by a tenth or two.
Usually not in the GPA: most colleges accept transfer credits toward graduation but do not import the grades, and pass/fail courses add credits without grade points. Withdrawals (W) are also excluded. Enter only graded courses taken at your current institution — and check whether your school replaces or averages grades on retakes.
Latin honors commonly start at 3.5 (cum laude), 3.7 (magna) and 3.9 (summa), though thresholds vary by school. Graduate programs typically ask for 3.0 minimum, competitive ones 3.5+, and law and medical schools look at 3.7+; many also recalculate a science or major GPA separately.
