How GPA Is Defined at Duke University
At Duke University, a Grade Point Average (GPA) is a weighted average of course grades earned in Duke courses. GPA is calculated by multiplying the grade point value of each letter grade by the course credit value, then dividing total quality points by total graded credits. Duke applies a standard grade point scale across undergraduate programs and many graduate and professional programs. Duke does not calculate GPA by major, minor, or certificate.
Who This GPA Calculator Is For
| Applies To | Does Not Apply To |
|---|---|
| Undergraduate students in Trinity College of Arts & Sciences | GPA within a major, minor, or certificate |
| Undergraduate students in the Pratt School of Engineering | Non-Duke coursework |
| Graduate and professional students in programs that report GPA | Programs or cohorts with no GPA reported |
| Students calculating semester or cumulative Duke GPA | Transfer course grades |
Transfer course grades are not included in any Duke GPA calculation, though approved interinstitutional coursework is included.
Before You Use the GPA Calculator
Before entering courses, confirm the following:

- You have the correct credit value for each course.
- You have excluded courses graded Pass/Fail, Satisfactory/Unsatisfactory, Credit, or No Credit.
- You are using the official Duke grade-to-points scale.
This calculator is intended to match Duke’s official semester and cumulative GPA calculations.

Which Courses Count Toward GPA
| Included in GPA | Not Included in GPA |
|---|---|
| Courses graded A–F with or without plus/minus | Pass/Fail courses |
| Interinstitutional Duke coursework | Satisfactory/Unsatisfactory |
| Standard graded Duke courses | Credit/No Credit |
| Transfer coursework |
Miscounts most often occur when non-graded or transfer courses are mistakenly included.
How Course Units Affect GPA at Duke University
Each course’s grade point value is multiplied by its assigned credit value to determine quality points. Courses with higher credit values have a proportionally greater impact on GPA.
How GPA Is Calculated
Official Formula
GPA = Total Quality Points ÷ Total Graded Credits
Quality points are calculated by multiplying grade points by course credits.
Example
Four courses, each worth 3 credits, with grades A, B+, B, and C:
- Quality Points:
A = 12.0
B+ = 9.9
B = 9.0
C = 6.0
Total = 36.9 - Total Graded Credits = 12
- GPA = 36.9 ÷ 12 = 3.075
Duke GPAs are truncated to three decimal places.
Course Repeats or Special GPA Rules
Duke does not publish a GPA replacement policy for repeated courses. All graded courses that qualify for GPA calculation are included according to registrar rules.
Transcript Grades vs GPA Calculations
Some transcript grades appear on the academic record but do not affect GPA. These include Pass, Satisfactory, Credit, and similar non-graded designations.
Graduate GPA
Some Duke graduate and professional programs calculate and report GPA. Other programs or earlier cohorts may show no GPA reported.
Graduate GPA calculation rules vary by school and program and follow official registrar and graduate school policies.
Common GPA Mistakes Students Make
- Including Pass/Fail or non-graded courses
- Including transfer grades
- Averaging term GPAs instead of calculating quality points
- Using an incorrect grade-to-points scale
