Semester GPA vs Cumulative GPA
Semester GPA measures your performance in one term. Cumulative GPA reflects your full academic record, weighted by credits completed.
Semester GPA
Semester GPA measures only the courses you completed in a single term. It is calculated by converting each letter grade to grade points, multiplying by the credit hours for that course, summing those values, and dividing by total credits taken that semester.
Semester GPA = total grade points this semester / total credits this semester
Example: Three courses — a 3-credit A (4.0), a 4-credit B+ (3.3), and a 3-credit B (3.0).
- Grade points: 3×4.0 + 4×3.3 + 3×3.0 = 12 + 13.2 + 9 = 34.2
- Total credits: 10
- Semester GPA: 34.2 / 10 = 3.42
Cumulative GPA
Cumulative GPA combines every semester you have completed. It weights each semester by the number of credits taken, so a semester with 15 credits influences the cumulative GPA more than a semester with 9 credits.
New cumulative GPA = (prior GPA × prior credits + semester grade points) / total credits
Example: You have a 3.0 cumulative GPA over 45 credits. This semester you earned 34.2 grade points across 10 credits.
- Prior grade points: 3.0 × 45 = 135
- Combined grade points: 135 + 34.2 = 169.2
- New total credits: 55
- New cumulative GPA: 169.2 / 55 = 3.08
Why cumulative GPA changes more slowly over time
In your first semester, your semester GPA and cumulative GPA are identical. By your fourth year, each new semester represents a small fraction of your total credits, so the cumulative GPA moves less dramatically. This is both good news (a bad semester hurts less) and a caution (a great semester helps less).

FAQ
Can one bad semester ruin my cumulative GPA?
It can lower it, but the damage depends on how many credits you have completed. Early in your college career, each semester has a larger effect. After 60 or 80 credits, a single difficult semester moves the cumulative GPA less because the new credits are a smaller share of the total.
Does semester GPA appear on my transcript?
Usually yes. Most college transcripts show both semester GPA and cumulative GPA. Employers and graduate programs typically look at cumulative GPA, but some may ask about individual semesters.
Which GPA do I report on job applications?
Most applications and resumes use cumulative GPA unless you have a strong reason to highlight a specific semester, major GPA, or upper-division GPA. When in doubt, report the cumulative GPA.
If I have a 2.8 cumulative GPA and get a 4.0 this semester, what happens?
Your cumulative GPA will improve, but by how much depends on the ratio of this semester's credits to your previous total. Use the Cumulative GPA Calculator to see the exact result for your situation.
