College GPA Calculator
Semester and cumulative GPA across all your college semesters.
Your semesters
Target planner (optional)
Cumulative GPA is the credit-weighted average of every semester: each semester's GPA multiplied by its credits, added together, then divided by total credits. Results are estimates — your school registrar is the official source. For a single semester's courses, use the GPA calculator.
What is a college GPA calculator?
A college GPA calculator combines your semester GPAs into one cumulative GPA — the number that appears on your transcript and that graduate schools, scholarships, and employers actually read. Because semesters carry different credit loads, it does not simply average the semester GPAs: a 15-credit semester counts more than a 9-credit one, so each semester's GPA is weighted by its credits before averaging.
Enter each semester's GPA and the credits you attempted, and the calculator shows your cumulative GPA, your total credits, and a per-semester breakdown table showing how many grade points each semester contributed. That breakdown makes it easy to see which semester is pulling your average up or down.
The target planner answers the planning question every student asks: what GPA do I need next semester to reach my goal? Enter a target cumulative GPA and the credits you will take next term, and it works out the semester GPA required. If the answer is above 4.0, the target is not reachable in one semester, and the calculator says so honestly — you can then plan over two semesters instead.
Results here are estimates based on the GPAs and credits you enter. Your school's registrar is the official source for your cumulative GPA, and policies on retakes, transfer credits, and grade replacement vary by institution.
How the college GPA calculator works
Semester by semester, then combined. Enter each semester's GPA and credit hours and the calculator combines them into your cumulative GPA, weighted by credits — exactly how a registrar does it. It also works backwards: enter your target cumulative GPA and it tells you the GPA you need next semester.
A semester with more credits moves your cumulative GPA more than a light semester. That is why a single bad semester early on is hard to undo — and why a strong final semester helps less than students hope.

How to use the college GPA calculator
- Enter each semester's name, semester GPA, and credits attempted. Add or remove semester rows with the buttons.
- Optionally enter a target cumulative GPA and the credits you will take next semester to plan ahead.
- Press Calculate cumulative GPA to see your cumulative GPA, total credits, and the per-semester breakdown.
- If you set a target, check the Reaching your target result for the semester GPA you need next term.
Frequently asked questions
How is cumulative GPA calculated from semester GPAs?
Each semester's GPA is multiplied by its credits to get grade points, the grade points are added together, and the total is divided by total credits. A 15-credit semester counts more than a 9-credit one — it is not a simple average of the semester GPAs.
What is the difference between semester GPA and cumulative GPA?
Semester GPA covers one term only. Cumulative GPA covers every semester you have completed, weighted by credits. Graduate schools and most employers look at cumulative GPA.
What GPA do I need next semester to reach my target?
Use the target planner above: enter your target cumulative GPA and next-semester credits, and the calculator works out the semester GPA required. If the required GPA is above 4.0, the target cannot be reached in a single semester.
Do transfer credits count toward my cumulative GPA?
It depends on your school. Many schools accept transfer credits toward your degree but do not include transfer grades in your GPA. Check your registrar's transfer policy — if they do not count, leave those semesters out.
Do failed or withdrawn courses affect cumulative GPA?
An F earns 0 grade points but its credits still count, which drags the average down. A withdrawal (W) usually does not affect GPA, though it has other consequences — talk to an advisor before deciding.
Can I raise a low cumulative GPA?
Yes, but it takes time: the more credits you already have, the slower the average moves. Strong grades in high-credit semesters help most, and retaking a failed course can help where your school replaces the old grade — check your retake policy.
