GPA Calculator

Calculate cumulative and semester GPA on a 4.0 scale.
Enter letter grades and credit hours to find your average and the grades needed to hit a target GPA.

Your GPA

GPA (Grade Point Average) is a weighted average of your academic grades, where each course is weighted by the number of credit hours it carries.

Unweighted GPA formula: GPA = Σ (Grade Points × Credit Hours) / Σ Credit Hours

Standard 4.0 grade point scale:

Letter Grade Grade Points
A+ / 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 0.0

Worked example (unweighted):

  • English Literature (A, 3 credits): 4.0 × 3 = 12.0
  • Calculus (B+, 4 credits): 3.3 × 4 = 13.2
  • Chemistry (B, 3 credits): 3.0 × 3 = 9.0
  • History (A−, 3 credits): 3.7 × 3 = 11.1
  • Total quality points: 12.0 + 13.2 + 9.0 + 11.1 = 45.3
  • Total credit hours: 3 + 4 + 3 + 3 = 13
  • GPA = 45.3 / 13 = 3.485 → rounds to 3.49

Weighted GPA adds bonus points for honors or AP courses:

  • Honors course: add 0.5 to the grade points
  • AP / IB course: add 1.0 to the grade points

Academic standing benchmarks:

  • 3.7–4.0: Dean’s List / Summa Cum Laude
  • 3.5–3.69: Magna Cum Laude
  • 3.0–3.49: Good standing
  • Below 2.0: Academic probation at most universities

Why credit hours change the answer so much

This is the part people get wrong when they average grades in their head. A GPA is weighted by credit hours, so a B in a four-credit course pulls harder than a B in a one-credit course. Two students with exactly the same set of letter grades can finish with different GPAs purely because of which courses those grades landed in. If you are deciding where to spend revision time late in a term, spend it on the heaviest course, not the one where you are closest to a boundary.

The calculator above is unweighted, deliberately

It caps A and A+ at 4.0 and applies no honors or AP bonus. That is the scale most transcripts report and the one graduate schools recalculate to, because weighted scales are not comparable between schools: one district’s 5.0 AP scale and another’s 4.5 honors scale mean different things. If your school reports a weighted GPA, treat it as a separate number rather than a better version of this one, and know which of the two an application is actually asking for.

A note on rounding. Institutions differ on whether 3.495 becomes 3.50 or 3.49, and on whether a cumulative GPA recomputes from all quality points or averages the term GPAs. Those give slightly different answers. If you are near a threshold that matters, the registrar’s figure is the one that counts, not this one.
