What Is a Good GPA at Purdue?

A GPA of 3.3 or higher is considered solid at Purdue, where the average undergraduate GPA hovers near 3.3. Dean's List threshold is 3.5 term GPA. Engineering and Computer Science cohorts often run lower averages due to rigorous technical grading.

The average undergraduate GPA at Purdue sits near 3.30, drawn from the Purdue registrar policy and aggregated reporting. Enter your courses in the calculator above to see where your cumulative GPA lands relative to that figure.

How Purdue Calculates GPA

Purdue University (Purdue) uses a 4.0 grade point scale and uses plus/minus modifiers (A-, B+, B-, and so on). The school caps A+ at the same 4.0 value as an A, which matters when converting letter grades from a transcript that records A and A+ separately. Each course's grade points multiply by its credit hours, those quality points sum across all courses, and the total divides by total credits attempted.

Purdue GPA Formula

GPA = Sum(Grade Points x Credit Hours) / Sum(Credit Hours)

Where:

Grade Points = letter-grade value on the 4.0 scale
Credit Hours = credit value of the course on the Purdue transcript
A+ = 4.0 (same as A on the standard scale)

Example: A 4-credit class with an A (4.0 points) and a 3-credit class with a B+ (3.3 points): quality points = 4 × 4.0 + 3 × 3.3 = 25.9, total credits = 7, GPA = 25.9 / 7 = 3.70.

Purdue Grading Policy Notes

Purdue uses the standard 4.0 scale with plus and minus modifiers. Repeat Course Forgiveness limited to two courses (max 8 credit hours) where the original grade was C-minus or worse. Engineering and CS courses are known for rigorous grading.

Purdue Honors and Recognition

Dean's List at Purdue

Purdue lists students with a GPA of 3.50 or higher on the Dean's List. The honor is computed per-term, so a single strong semester earns recognition even if the cumulative GPA sits lower.

Academic Standing and Repeat Policy at Purdue

Academic Probation Threshold

Purdue places students on academic probation when their cumulative GPA drops below 2.0. Probation usually triggers mandatory advising, restricts course registration, and can affect financial aid or scholarships. Use the calculator to model remaining semesters and see how many A or B grades would lift the GPA back above the 2.0 floor.

Repeating a Course at Purdue

Under Purdue's repeat policy, the new grade replaces the old grade in the GPA calculation. This calculator treats every entered row as a distinct graded attempt; if your school replaces the old grade, leave off the original, and if both count, enter both lines. Always confirm the final transcript version with the registrar before relying on a projected GPA.

Grade Forgiveness at Purdue

Yes. Purdue offers a Repeat Course Forgiveness Policy that allows students to retake up to two courses (max 8 credit hours) where they earned a C-, D, or F. The repeat grade replaces the original in the GPA, though both stay on the transcript.

Major GPA Requirements at Purdue

Most majors require 2.0 minimum. Engineering admission to the major (CODO process) typically requires 2.5-3.0 in technical prerequisites depending on the department.

Accuracy Note

This calculator follows the grading policy published by the Purdue registrar as of 2026-04-18. Policies are reviewed periodically; the "Last verified" date in the footer reflects the most recent confirmation. Always cross-check your final GPA against your official transcript. The tool models the same formulas registrars use but cannot account for grade forgiveness petitions, audit decisions, or exceptions approved by the dean of students.

Frequently asked questions

How Does Purdue Calculate GPA?

Purdue calculates GPA by converting each letter grade to grade points on the 4.0 scale, multiplying by the course's credit hours, summing the quality points, and dividing by total credits attempted. Plus/minus modifiers and course repeats follow Purdue's published registrar rules, the calculator above mirrors the same arithmetic. For a quick check on where your current term sits, enter each course with its grade and credit load and compare the result to the Dean's List and probation thresholds. Always verify with your specific school's registrar.

How Does Purdue Calculate GPA High School?

Purdue admissions reviews your reported high school GPA in context with your course rigor, school profile, and official transcript. The calculator above converts letter grades to 4.0 grade points (A = 4.0, B = 3.0, C = 2.0, D = 1.0) and weights each course by credit or Carnegie unit. Honors, AP, and IB courses typically carry a weighted bonus on applicant reports, though Purdue recalculates on an unweighted basis for internal review. Always verify with your specific school's registrar.

How do I calculate my Purdue GPA?

Enter each Purdue course you have taken, select your letter grade, and enter the credit hours from your transcript. The calculator converts each grade into grade points on the standard 4.0 scale, multiplies by credit hours, and divides by total credits. Purdue uses plus/minus modifiers (A-, B+, B-, and so on) and caps A+ at the same 4.0 value as an A, which this calculator reflects by default.

What GPA do I need for the Purdue Dean's List?

Purdue requires a GPA of 3.50 or higher to qualify for the Dean's List. Dean's List at this school is computed term-by-term, so a single strong semester can earn recognition even if cumulative GPA is lower.

What is the GPA cutoff for academic probation at Purdue?

At Purdue, students fall into academic probation when their GPA drops below 2.0. Probation status typically restricts course registration, triggers mandatory advising, and may affect financial aid eligibility. Use this calculator to check where your current term and cumulative averages land relative to the 2.0 floor.

Does Purdue award Latin honors at graduation?

Purdue does not publish fixed Latin honors GPA thresholds that apply across all undergraduate programs. Purdue uses two lists: Semester Honors (3.5+ term GPA with 12+ hours) and Dean's List (top quartile of each college, typically 3.7+).

If I retake a course at Purdue, how does it affect my GPA?

Purdue's repeat policy is that the new grade replaces the old grade in the GPA calculation.
