GPA Calculator
Add your courses, pick your grades, and get your semester and cumulative GPA — weighted or unweighted, on a 4.0 or 5.0 scale.
How it works
Behind the numbers
GPA is a credit-weighted average. Each letter grade converts to grade points (A = 4.0), multiplied by the course's credit hours, summed across courses, and divided by total credits. A 4-credit A moves your GPA twice as much as a 2-credit A — credits are the weights.
Weighted GPA adds a bonus (often +1.0) for honors, AP, or IB courses on a 5.0 scale; unweighted caps everything at 4.0. Toggle the scale to match how your school reports it. Colleges often recalculate anyway, but you should know both numbers.
Enter your prior cumulative GPA and completed credits to fold in your history, or open the target planner: tell it the GPA you want and the credits you have left, and it computes the average grade you need from here on out.
FAQ
Questions, answered
How is GPA calculated?
Each grade converts to grade points, multiplied by the course's credit hours. Sum those quality points and divide by total credit hours. That is your GPA.
What is the difference between weighted and unweighted GPA?
Unweighted caps every course at 4.0. Weighted adds a bonus — typically +1.0 — for honors, AP, or IB courses, on a 5.0 scale, rewarding harder courseloads.
What GPA do I need for college admissions?
It varies widely by school. The target planner above works backwards: enter your desired GPA and remaining credits to see the average grade you need.
Do colleges look at weighted or unweighted GPA?
Many recalculate GPA using their own formula from your transcript. Report what your school provides, but know both versions of your number.
Can I still raise my GPA as a junior or senior?
It depends on the math: remaining credits divided by total credits sets the ceiling. The planner quantifies exactly what is possible — sometimes the answer is encouraging, sometimes it is a reality check.
