How the Princeton University GPA formula works

Princeton University converts every graded course into quality points by multiplying the grade's point value by the course's credit hours. Your semester GPA is the total quality points divided by the total credit hours that count toward the GPA, and the result is rounded to the nearest 2 decimal places. Points run from 0.0 up to 4.0, so a higher average is a better result. The scale uses plus and minus grades, so there are 11 distinct point values rather than a handful of whole steps: A+ is worth 4.0 and A is worth 4.0.

What gets left out of the average

AUD, P, INC, and W carry no point value at Princeton University, so a course marked with one of them drops out of the division entirely — it changes neither the top nor the bottom of the fraction. P still earns credit toward your degree while staying out of the GPA, which is why your credit total can climb in a semester where your GPA barely moves. F works the other way: it earns no credit but is still counted in the average at 0.0 points, so a failed course pulls the average down while adding nothing to your progress.

How this semester rolls into your CGPA

Princeton's official conversion guidance multiplies grade point value by semester hours, then divides total points by total semester hours for courses graded A+ through F. In practice that means your existing CGPA is turned back into quality points by multiplying it by your completed credits, this semester's quality points are added on, and the total is divided by your new credit total. Both the semester and the cumulative figures are rounded to the nearest 2 decimal places. Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.

How Princeton University compares with other United States universities

Princeton University is the only United States university covered here using the 4.00 GPA conversion scale; the other 11 universities on this site grade on different scales entirely, so their GPA numbers are not comparable with yours. Rounding is not uniform either: Princeton University has its cumulative average rounded to the nearest 2 decimal places, whereas Duke University, Massachusetts Institute of Technology and 1 other do it differently. Repeated courses are handled differently again at Massachusetts Institute of Technology and New York University College of Arts and Science.

A GPA only means something alongside the scale it was calculated on, which is why comparing raw numbers between institutions — even neighbouring ones — is unreliable. See the United States comparison table for every university covered there side by side.

Worked examples

Each example below is run through the same engine the calculator uses, so the numbers show Princeton University's own rounding.

A typical graded semester

A student sitting at 2.88 after 60 completed credits takes 3 courses worth 3 credits each.

  • Core course3 credits × A+ (4.0 points)
  • Elective3 credits × A- (3.7 points)
  • Lab or seminar3 credits × B (3.0 points)

Semester GPA 3.57 · Updated CGPA 2.97

The semester total is 32.1 quality points over 9 counted credits. Because the cumulative average now spans 69 credits, one semester moves it only a little — this is why a CGPA gets harder to shift the further into a degree you are.

Adding a course graded P

The same student adds a fourth 3-credit course graded P (Pass).

  • Core course3 credits × A+ (4.0 points)
  • Elective3 credits × A- (3.7 points)
  • Lab or seminar3 credits × B (3.0 points)
  • Pass course3 credits × P (no grade points)

Semester GPA 3.57 · Updated CGPA 2.97

The semester GPA is unchanged at 3.57. P carries no grade points at Princeton University, so the course is removed from both sides of the division — even though the credit still counts toward the degree. Students often expect a fourth course to move the average and are surprised when it does not.

What one F costs

The same semester again, but the last course comes back as F (F) instead.

  • Core course3 credits × A+ (4.0 points)
  • Elective3 credits × A- (3.7 points)
  • Failed course3 credits × F (0.0 points)

Semester GPA 2.57 · Updated CGPA 2.84

The semester GPA slips from 3.57 to 2.57, and the cumulative average slips from 2.97 to 2.84. F is worth 0.0 points and earns no credit, so it weighs the average down while adding nothing to your degree progress.

What this semester does to your CGPA

A student with a 2.88 CGPA after 60 credits takes 4 courses worth 3 credits each (12 credits in total). Here is where that CGPA lands if every course comes back at the same grade — calculated with the Princeton University scale and rounding.

Common mistakes when calculating your Princeton University GPA

These are the places where the Princeton University rules differ from what most students assume, and where a hand calculation usually goes wrong.

  1. Counting P courses in the average

    These earn credit at Princeton University but carry no grade points, so they belong in your credit total and nowhere near the GPA division. Including them is one of the most common reasons a hand-calculated GPA comes out wrong.

  2. Dropping a failed course from the calculation

    F earns no credit toward the degree, but it is still counted in the GPA at 0.0 points. Leaving a failure out flatters the result.

  3. Guessing the plus/minus values

    At Princeton University, A+ is worth 4.0 and A is worth 4.0. Those steps differ between universities, so a value copied from another school's chart will quietly skew the whole average.

  4. Averaging the grades instead of weighting them

    A course worth twice the credits moves your GPA twice as much. Adding up your grade points and dividing by the number of courses ignores that weighting and is almost always wrong.

  5. Expecting a 0-credit course to move the number

    Princeton University allows them, but with no credit hours they contribute nothing to either side of the division.

  6. Handling a retake by guesswork

    Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog. Check the current catalog before assuming an old grade has left your record.

Princeton University GPA — frequently asked questions

What is a passing grade at Princeton University?

D (1.0 points) is the weakest grade in the Princeton University table that still earns credit. Anything below it — F — is counted in your GPA but earns no credit toward the degree. Individual programmes can set a higher minimum for courses in your major, so check your programme handbook as well.

What is the best GPA you can get at Princeton University?

4.0 on the 4.00 GPA conversion scale, which you reach by earning A+ (4.0 points) in every course that counts toward the GPA.

Does Princeton University round GPA up?

The cumulative average is rounded to the nearest 2 decimal places, and the semester average is rounded to the nearest 2 decimal places. That is ordinary rounding, so a result sitting exactly half a step along goes up.

Is this a generic United States GPA formula?

No. This page is generated from the grading configuration for Princeton University alone — its 11 point values, its standard rounding, and its own rules for pass/fail and repeated courses. Other universities in United States routinely use different point values or a different scale entirely, so the same grades can produce a different GPA elsewhere.

Do pass/fail courses affect my GPA?

No. P earns credit at Princeton University without carrying grade points, so it is excluded from the GPA division entirely. Your completed-credit total goes up while the average stays where it was.

Which grades are excluded from the Princeton University GPA?

AUD (Audit), P (Pass), INC (Incomplete), and W (Withdrawal) carry no grade points and are left out of the average. Of those, P still earn credit toward the degree.

What happens to my GPA if I repeat a course?

Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.

How much does one semester change my cumulative GPA?

Your CGPA is weighted by every credit you have already completed, so a single semester moves it less the further along you are. Fifteen credits added to sixty already completed is a fifth of your record; the same fifteen added to a hundred and twenty is an eighth of it. Use the calculator at the top of this page with your real completed-credit total rather than estimating the movement.

Is this calculator official?

No. GPAWorld is an independent tool and is not affiliated with or endorsed by Princeton University. The grading data on this page was taken from Princeton University Registrar - Calculate Your GPA and last verified on 2026-07-21; every source is linked on this page so you can check it yourself.

Notes on this university's data

Judgement calls and caveats recorded when this grading configuration was built from the official sources. They are published so you can see exactly what the calculator assumes.

  • Princeton University has its own official GPA conversion guidance and is not treated as a generic United States formula.
  • Princeton states it does not officially compute or certify GPA; this config follows its official self-calculation guidance for users who need to submit a GPA.
  • AUD, P, INC, and W are excluded from GPA according to Princeton's official conversion instructions.
  • Repeated-course handling is manual review because the cited official GPA conversion page does not define a repeat replacement rule.
