GPA Calculator
Calculate your grade point average across multiple courses.
What Is the GPA Calculator?
A GPA calculator converts your grades and credit hours into an exact grade point average on the standard four point scale. GPA compresses transcript complexity into one number that scholarship committees, graduate programs, employers, and athletic eligibility offices all read. The math is weighted averaging: each course contributes its grade points multiplied by credit hours, divided by total credits attempted. That weighting explains why a strong grade in a four credit lab science moves your average more than the same grade in a one credit seminar. Use this tool to project semester outcomes, check standing against targets, or model what retaking a course would do.
Key Statistics
-
4.0 scale
The most common US grading scale where A equals 4.0 quality points
Source: Standard US academic convention
-
+0.3
Typical bump for plus grades like B plus at many institutions
Source: Common institutional policy
The Formula
GPA = Sum of (Grade Points x Credits) / Total Credits. A=4.0, B=3.0, C=2.0, D=1.0, F=0.0.
Worked Examples
A 3 credit A course earns 12 quality points, and a 4 credit B course earns 12 points, totaling 24 points across 7 credits for a 3.43 GPA. Adding a 3 credit C course worth 6 points drops the average to 30 points over 10 credits for a 3.00 GPA.
Semester GPA with credits
- Grades: A in a 3 credit course, B plus in 4 credits, B in 3 credits
- Quality points: 4.0 times 3 plus 3.3 times 4 plus 3.0 times 3
- Sum equals 34.2 across 10 total credits
Semester GPA is 3.42.

Expert Tips
- ✓ Confirm your institution's plus and minus policy since scales vary between schools.
- ✓ Weighted versus unweighted GPA matters for high schoolers; know which one a reader expects.
- ✓ Pass fail courses usually bypass GPA entirely but still count toward enrollment status.
- ✓ Cumulative GPA recovers slowly, so early semester vigilance beats late heroics.
Frequently Asked Questions
How is GPA calculated? ▼
Multiply each course grade value by its credit hours to get quality points, add them all up, then divide by the total credits. An A in a 3 credit course earns 12 quality points on the 4.0 scale.
What is the difference between weighted and unweighted GPA? ▼
Unweighted GPA puts every course on the same 4.0 scale. Weighted GPA adds bonus points for harder courses like Honors, AP, or IB, so it can go above 4.0 to reward rigor.
What is a good GPA? ▼
A GPA above 3.0 is generally solid, 3.5 and up is strong, and 3.7 and above often qualifies for honors. What counts as good also depends on your major and your goals.
How do I calculate my cumulative GPA? ▼
Combine your previous quality points and credits with this term. Multiply your past GPA by your past credits, add this term quality points, and divide by the total credits.
What is the difference between semester and cumulative GPA? ▼
Semester GPA covers only the courses in one term. Cumulative GPA covers every course you have taken across all semesters and is what appears on your transcript for scholarships and graduate programs.
Do pass or fail courses count toward GPA? ▼
Usually no. Pass or fail grades, withdrawals, and incompletes are typically left out of the GPA calculation. They appear on your transcript but do not raise or lower your average.
How is GPA calculated? ▼
Multiply each course's quality points by its credit hours, sum those products, then divide by total credit hours attempted.
Do pass fail classes affect GPA? ▼
Generally no. They count toward credits earned but contribute no quality points either direction.
Common Mistakes to Avoid
- ⚠ Forgetting that credit hours weight the GPA (a B in a 4-credit course affects your GPA more than an A in a 1-credit course).
- ⚠ Mixing weighted GPA (AP/IB courses worth up to 5.0) with unweighted GPA (capped at 4.0) in the same calculation.
- ⚠ Including pass/fail or withdrawal courses in the GPA total when most schools exclude them from the calculation entirely.
- ⚠ Averaging grades without weighting by credits. A four credit course must count twice as much as a two credit course.
