GPA Calculator

Grade point average (GPA) is total grade points earned divided by total credit hours attempted. Each letter grade maps to a point value on a 4.0 scale — A = 4.0, A− = 3.7, B+ = 3.3, and so on.

Weighted honors or AP courses may use a 5.0 scale at some schools; this calculator uses the standard unweighted 4.0 mapping. Check your transcript policy before comparing results to official records.

Example: an A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course yield (4.0×3 + 3.0×4) ÷ 7 = 3.43 GPA.

GPA is a credit-weighted average, not a simple average of grades. A 4-credit course pulls harder than a 1-credit seminar, so an A in a lab and a C in a one-credit elective land far above the midpoint. This is why students often misjudge a term: dropping a low grade in a heavy course helps much more than fixing a light one.

Semester and cumulative GPA use the same arithmetic on different inputs. For a cumulative figure, enter every graded course on the transcript, not just the current term — and note that a large completed credit base makes each new term move the number less. After 90 credits at 3.20, even a perfect 15-credit term only lifts the cumulative to about 3.31.

Not every enrolled course counts. Pass/fail and credit/no-credit courses normally earn credit without grade points and are excluded from the calculation entirely, while withdrawals usually leave a W that affects neither. Transfer credits often count toward the degree but not toward the GPA at the receiving institution — check your registrar's policy before including them.

Repeated courses are the most common source of mismatch with the portal. Some schools replace the original grade, others average both attempts, and a few count both attempts in credits attempted while using only the higher grade. Enter whichever your institution actually applies, since the three policies can differ by a tenth of a point or more.

Rounding is where a calculated GPA and an official transcript diverge. Institutions vary between truncating at two decimals and rounding half-up, which is enough to decide a 3.499 sitting on a 3.5 honours cutoff. Treat a result within about 0.01 of a threshold as unresolved until the registrar's figure is published.

Institutional rounding on transcripts may differ by ±0.01 from this calculator — check whether your school truncates or rounds half-up.
