College GPA Calculator

Your Grade Point Average (GPA) is determined by multiplying the numerical value of each letter grade by the credit hours assigned to that course, summing those products together, and then dividing by the total number of credit hours attempted. The standard 4.0 grading scale generally assigns an A as 4.0, B as 3.0, C as 2.0, D as 1.0, and F as 0.0. Mathematically, the formula is expressed as GPA = Sum of (Grade Points x Credits) / Total Credits Attempted. Cumulative GPA (CGPA) expands this formula to include all historical semesters combined.

Imagine you are taking three classes this semester: Organic Chemistry (4 credits, grade of B = 3.0), Calculus II (3 credits, grade of A = 4.0), and World History (3 credits, grade of C = 2.0). First, multiply each grade point by its credit weight: Chemistry gives 4 x 3.0 = 12.0 grade points; Calculus gives 3 x 4.0 = 12.0 grade points; History gives 3 x 2.0 = 6.0 grade points. Next, sum these grade points: 12.0 + 12.0 + 6.0 = 30.0 total grade points. Finally, divide by your total credit hours (4 + 3 + 3 = 10 credits). Your semester GPA is 30.0 / 10 = 3.0.

Always double-check whether your institution uses plus (+) and minus (-) grading modifiers, as these can slightly alter your grade points (e.g., a B+ is typically 3.3). When planning for future semesters, input your cumulative credits and current CGPA alongside your prospective classes to forecast how upcoming grades will impact your standing. Avoid waiting until finals week to check your numbers; keeping a running estimate helps you identify when you need extra tutoring or office hours.
