How do I calculate my GPA?

Convert each letter grade to grade points (A=4.0 through F=0), multiply each by its course credits, add those products, then divide by your total credits. The tool above does this automatically — paste your grades, enter credits per course, and it returns your GPA rounded to 2 decimals.

How is GPA calculated on a 4.0 scale?

On the standard US 4.0 scale each letter grade maps to points: A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D+=1.3, D=1.0, F=0. The GPA is the credit-weighted average of those points. This calculator uses exactly that scale — check your school if it uses different cutoffs.

What is the difference between semester GPA and cumulative GPA?

Semester GPA covers one term's courses; cumulative GPA covers every course you have ever completed. To get a cumulative GPA with this tool, list all courses from all terms so far (one grade per line) using each course's credit value.

Can I calculate my GPA if my courses have different credit hours?

Yes — GPA is credit-weighted, so a 4-credit A counts more than a 1-credit A. This tool takes a single "credits per course" value for a uniform load; for a mixed load, list courses per credit value separately or add courses in batches and weight them yourself.

What is a good college GPA?

A 3.0 or higher is generally considered good, 3.5+ is strong for competitive programs, and many scholarships require 3.0-3.5. Context matters: grading difficulty varies by school and major, so treat the number as one signal among many.

What is Gpa calculator?

GPA Calculator — Calculate your GPA free — enter letter grades and course credits to get an accurate semester GPA on the US 4.0 scale, with total credits counted.

Credit-weighted GPA: each letter grade maps to grade points on the US 4.0 scale (A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D+=1.3, D=1.0, F=0), then GPA = sum(grade points x credits) / sum(credits), rounded to 2 decimals. The computation is the pure credit-weighted engine extracted from the MIT-licensed vishwakaran12/gpa-calculator (vendored), which is itself a DOM app. Limitations: the tool cannot know your school's own +/- cutoffs or retake/pass-fail policies; an unrecognized grade letter is rejected rather than guessed.

How it works

Credit-weighted GPA: each letter grade maps to grade points on the US 4.0 scale (A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D+=1.3, D=1.0, F=0), then GPA = sum(grade points x credits) / sum(credits), rounded to 2 decimals. The computation is the pure credit-weighted engine extracted from the MIT-licensed vishwakaran12/gpa-calculator (vendored), which is itself a DOM app. Limitations: the tool cannot know your school's own +/- cutoffs or retake/pass-fail policies; an unrecognized grade letter is rejected rather than guessed.

Examples

Three 3-credit courses: A, B+, A-

Status: ok — GPA 3.67, total credits 9, courses counted 3.

One course: F

Status: ok — GPA 0, total credits 4, courses counted 1.

Invalid grade letter

Status: error — line 2 names "E", which is not on the US 4.0 scale.
