About GPA Calculator (grade Point Average) Online
This tool calculates your Grade Point Average (GPA) using the standard 4.0 scale. Enter each course's letter grade (A, B+, C, etc.) and credit hours, and the calculator returns your weighted GPA — the standard metric used by U.S. colleges, graduate schools, and employers.
GPA is weighted by credit hours, so a four-credit A counts more than a two-credit A. The tool handles + and − modifiers (A−, B+) according to the standard scale (4.0, 3.7, 3.3, 3.0, 2.7…) and lets you mix completed courses with planned ones to project a final GPA.
Use it to track your cumulative GPA semester by semester, to set realistic targets for the remaining semesters, or to project the impact of retaking a course.

How to compute a Grade Point Average (GPA)
Enter one course per line
The "Pairs grade,credits per line" field takes one course per line as `grade,credits` — for example `3.7,3` on one line, `4.0,4` on the next. Up to 2,000 characters total.
Grades and credits are numbers
"Grade" is on whatever scale your school uses (4.0, 5.0, 10, etc.). "Credits" is the weight — usually credit hours or units. Any line that doesn't parse as `number,number` throws "Bad line: <line>".
Press Run
Result is gpa = Σ(grade × credits) / Σ(credits), rounded to 3 decimals. If all your credits are 0, you get "No credits." — divide-by-zero isn't a GPA.
Scale matters
The tool doesn't know your scale — it just averages numbers. A 4.0 system input alongside a 10-point grade will produce nonsense. Stay on one scale per run.
