Semester GPA Formula
GPA = Σ (Grade Points × Credit Hours) ÷ Total GPA Credit Hours
Example: ENGL 106 A (4.00) × 3cr + MA 161 B+ (3.30) × 4cr = (12.00 + 13.20) ÷ 7 = GPA 3.600
CGPA Formula
CGPA = Σ (Semester GPA × Semester GPA Hours) ÷ Total GPA Hours
Pass/Not-Pass and Special Purdue Marks
Purdue uses several academic marks that do not affect semester GPA or cumulative GPA. P means Pass under the Pass/Not-Pass option and generally reflects C- or higher work. N means Not Pass. I is an Incomplete mark. W, WF, WU are withdrawal marks. AU means Audit. These marks should not be entered as GPA-grade rows in this calculator.
"Use only credit-bearing letter grades when calculating Purdue GPA. For P, N, I, W, WF, WU, and AU, keep the course on your transcript record but exclude it from GPA points and GPA hours."
Purdue GPA Requirements & Academic Standing
Purdue academic standing depends on student level and program rules. For undergraduate degree completion, students generally need a minimum cumulative GPA of 2.00. Graduate students usually need a 3.00 GPA to remain in good academic standing.
| GPA Range | Standing | What It Means |
|---|---|---|
| 3.70 - 4.00 | Excellent | Strong academic performance on the Purdue 4.0 scale |
| 3.30 - 3.69 | Very Good | Above average performance with strong grade points |
| 3.00 - 3.29 | Graduate Good Standing | Common minimum benchmark for graduate-level standing |
| 2.00 - 2.99 | Undergraduate Satisfactory | Meets the common undergraduate minimum degree threshold |
| Below 2.00 | Academic Risk | Below undergraduate graduation minimum, improvement needed |
Course repetition note: If a Purdue course is repeated, the most recent grade is used in the official cumulative GPA calculation. For best accuracy, use the latest attempt when estimating your Purdue CGPA.
