GPA Calculator
Calculate your GPA the way US colleges do — letter grades on the 4.0 scale, weighted by credit hours.
| Course | Grade | Credits |

What is this tool?
Your grade point average decides more than bragging rights in the US: scholarships, Dean's List honors, athletic eligibility, internships and even some entry-level jobs ask for it. This GPA calculator uses the standard unweighted 4.0 scale used by most American high schools and colleges, where an A is worth 4.0 points and each course counts in proportion to its credit hours.
The credit weighting is the part students most often get wrong by hand. A B in a 4-credit lab science pulls your GPA down more than an A in a 1-credit seminar lifts it, because the calculator multiplies each grade's points by its credits before averaging. Add a row for every course, choose the letter grade you earned (or expect), and keep an eye on the projected GPA as you plan next semester.
How to use it
- One row per course: type the course name (optional), pick the letter grade, and enter its credit hours.
- Click Add course for more rows, or Remove to delete one.
- Click Calculate GPA to see your weighted average and total credits.
Formula & method
Worked example
English 101 (3 credits, A) earns 12 points; Biology (4 credits, B) earns 12 points; Algebra (3 credits, A−) earns 11.1 points. Total: 35.1 points over 10 credits, a GPA of 3.51 — comfortably Dean's List territory at most colleges.
Frequently asked questions
What GPA do I need for the Dean's List?
Most US colleges set the Dean's List cutoff between 3.5 and 3.7 for a semester, usually with a minimum of 12 credit hours. Check your school's catalog for its exact threshold.
Is a weighted GPA different?
Yes. Weighted GPAs give extra points for honors, AP or IB classes — often 5.0 for an A — which is why weighted GPAs can exceed 4.0. This calculator uses the unweighted 4.0 scale colleges recalculate with.
How can I raise my GPA quickly?
Retaking a failed course (where the school replaces the grade) is the fastest lever. Otherwise, focus on high-credit courses: an A in a 4-credit class moves your average more than any 1-credit elective can.
