Calculated using standard mathematical and industry formulas.
To calculate your Grade Point Average (GPA), multiply each course grade point value by its credit hours to determine total quality points, then divide by the total number of attempted credits. On the standard 4.0 scale, an A equals 4.0, B equals 3.0, and C equals 2.0. This calculator determines semester and cumulative academic standing.

Formula & calculation method
How Grade Point Average is calculated
GPA = Total Quality Points / Total Credit Hours; Quality Points = Σ (Course Grade Points × Course Credits); Cumulative GPA = (Prior Quality Points + Current Semester Points) / (Prior Credits + Current Credits)
Grade Points for a course = (Grade Point Value) × (Credit Hours). Grade values: A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D+=1.3, D=1.0, F=0.
A weighted GPA factors in credit hours: a 4-credit course has a greater impact on your GPA than a 1-credit lab.
The standard 4.0 scale assigns A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0, with 0.3 additions or subtractions for pluses and minuses.
As you accumulate more total credits, individual course grades have a progressively smaller effect on your cumulative GPA.
Most graduate programs and honor societies require a minimum cumulative GPA of 3.0 or 3.5.
Replacing an old grade (if your school allows grade forgiveness) recalculates your cumulative GPA by removing the previous course points.
How to interpret your results?
What is a Good GPA?
A 3.0 GPA (B average) is the general national benchmark for good academic standing and college graduation. A 3.5+ GPA qualifies students for Dean's List and competitive graduate programs, while 3.8+ contends for Latin honors (Cum Laude, Magna Cum Laude).
Unweighted vs. Weighted GPA
Unweighted GPA caps all courses at 4.0 regardless of difficulty. Weighted GPA grants bonus points for Advanced Placement (AP) or honors courses (scaling up to 5.0), reflecting course rigor.
Expert advice & guidance
💡 Academic tip: If your cumulative GPA falls close to a 2.0 academic probation threshold, retaking courses with D or F grades often replaces the failing grade on institutional GPA recalculations, boosting your average faster.
Frequently asked questions
How to calculate GPA and how to work out a cumulative GPA?
To calculate GPA: convert each letter grade into numeric points (A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, D=1.0, F=0.0). Multiply points by course credit hours to get quality points. Add all quality points together and divide by total credit hours taken.
What is a good GPA and is a 3.0 or 3.5 GPA considered good?
A 3.0 GPA (B average) is considered good and satisfies general college graduation and corporate hiring requirements. A 3.5 GPA (B+ to A- average) is very good, putting you in the top 20% of most colleges. A 3.7 to 4.0 GPA is competitive for top-tier law, medical, and graduate schools.
What is the highest GPA you can get on 4.0 and weighted scales?
On an unweighted scale, 4.0 is the highest possible GPA, representing straight A grades in all courses. On a weighted scale that includes Advanced Placement (AP), International Baccalaureate (IB), or Honors courses, the maximum GPA can reach 5.0 (or higher in rare school districts).
Is a D a passing grade in college and high school?
In high school and general college electives, a D grade (1.0 GPA) is technically passing and earns credit. However, in major core prerequisites and professional degree programs, colleges typically require a minimum C grade (2.0 GPA) for credit to count toward graduation.
What does GPA stand for and what is a cumulative GPA?
GPA stands for Grade Point Average. A semester GPA measures your academic performance for a single academic term, while cumulative GPA represents the weighted average of all grades earned across your entire academic career at an institution.
