Calculate your grade point average from letter grades and credit hours instantly.
A Grade Point Average (GPA) is a numeric representation of a student's academic performance, calculated by averaging the grade points earned across all courses, weighted by credit hours. The most common scale in the United States runs from 0.0 to 4.0, where 4.0 represents a perfect A in every course.
GPA is used by colleges and universities to assess academic standing, determine eligibility for scholarships and honors programs, and guide decisions about graduation with distinction. Employers and graduate schools often use GPA as one factor in evaluating candidates, particularly early in a person's career when other credentials are limited.
Credit hours weight the calculation — a 4-credit lab course has twice the GPA impact of a 2-credit seminar. This means performing well in high-credit-hour courses has a disproportionately large effect on your overall average. Understanding this dynamic helps you prioritize which courses to invest more effort in.
Quality Points per course:
Quality Points = Grade Points × Credit Hours
GPA:
GPA = Total Quality Points / Total Credit Hours
Example:
Math (A, 3 credits) = 4.0 × 3 = 12 quality points
English (B+, 3 credits) = 3.3 × 3 = 9.9 quality points
Physics (A-, 4 credits) = 3.7 × 4 = 14.8 quality points
Total credits: 10
Total quality points: 36.7
GPA: 36.7 / 10 = 3.67
| Letter Grade | Grade Points | Typical % |
|---|---|---|
| A+ | 4.0 | 97–100% |
| A | 4.0 | 93–96% |
| A- | 3.7 | 90–92% |
| B+ | 3.3 | 87–89% |
| B | 3.0 | 83–86% |
| B- | 2.7 | 80–82% |
| C+ | 2.3 | 77–79% |
| C | 2.0 | 73–76% |
| C- | 1.7 | 70–72% |
| D+ | 1.3 | 67–69% |
| D | 1.0 | 63–66% |
| D- | 0.7 | 60–62% |
| F | 0.0 | Below 60% |
3.9 – 4.0 GPA
Summa Cum Laude
Highest distinction. Competitive for top graduate programs and fellowships.
3.7 – 3.89 GPA
Magna Cum Laude
High distinction. Strong for graduate school applications and competitive employers.
3.5 – 3.69 GPA
Cum Laude
With honors. Above average; qualifies for most academic recognition programs.
3.0 – 3.49 GPA
Good Standing (B)
Above average. Meets requirements for most graduate programs and professional schools.
2.0 – 2.99 GPA
Satisfactory
Meets minimum graduation requirements at most institutions.
Below 2.0 GPA
Academic Probation Risk
Many schools require a minimum 2.0 GPA to remain in good standing. Below this triggers academic review.
GPA = Sum of (Grade Points × Credit Hours) / Total Credit Hours. Example: A (4.0) in a 3-credit course and B (3.0) in a 4-credit course: (12 + 12) / 7 = 3.43 GPA.
3.5–4.0 is excellent. 3.0–3.5 is above average. 2.5–3.0 is average. Below 2.0 may trigger academic probation at many schools.
A 3.0 GPA corresponds to a B on the standard 4.0 scale.
Standard GPA uses a 4.0 scale for all courses. Weighted GPA (common in high school) awards extra points for AP or honors courses — often 5.0 for an A. College GPAs are typically unweighted.
Enter all courses from every semester into the calculator. Include each grade and credit hours. The calculator weights by credits and returns your true cumulative GPA.
Typical thresholds: Cum Laude 3.5+, Magna Cum Laude 3.7+, Summa Cum Laude 3.9+. Requirements vary by institution.
At most US schools, A+ and A both equal 4.0 quality points. Some institutions award 4.3 for A+. Check your school's specific policy.
The more credits completed, the harder it is to move your average. Focus on high-credit courses where an A has maximum impact. Grade replacement (retaking courses) helps where policies allow.
Calculation method: GPA = Σ(Grade Points × Credits) / Σ(Credits). Grade point values use the standard US 4.0 scale (A/A+ = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, etc.).
