Standard unweighted 4.0 scale. Add your courses per semester — GPA updates live, weighted by credits.
The 4.0 scale used here
A+ 4.0 · 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 · D− 0.7 · F 0.0
Schools vary — some count A+ as 4.3 or weight honours courses. This calculator uses the plain scale above.
Calculate GPA the simple way: add your courses with credits and grades for a per-semester GPA, then stack semesters for a cumulative GPA on the 4.0 scale.

Calculate GPA the simple way: add your courses with credits and grades for a per-semester GPA, then stack semesters for a cumulative GPA on the 4.0 scale.
Four courses — 4 credits at A, 3 at B, 3 at A− and 2 at B+ — give (16 + 9 + 11.1 + 6.6) ÷ 12 credits = a 3.56 semester GPA. Add a second, stronger semester and the cumulative figure blends the two, with the heavier-credit semester pulling more weight, as it should.
Each grade converts to grade points on the standard 4.0 scale (A = 4.0, A− = 3.7, B+ = 3.3, and so on down to F = 0). A course contributes its points multiplied by its credits; GPA is total points divided by total credits, so a 4-credit A lifts you more than a 1-credit A. Cumulative GPA pools every semester’s points and credits together rather than averaging the semester GPAs — the mathematically correct weighting. The plus and minus grades matter, too: the 0.3 step between a B+ and a B is exactly why two students with "mostly Bs" can hold noticeably different GPAs.
The standard scale: A+ and 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, D− = 0.7 and F = 0. The full scale is printed beside the calculator for reference.
Averaging treats a 9-credit semester and an 18-credit semester as equals. Cumulative GPA pools all points and all credits first, so bigger semesters count more — which is how registrars actually compute it.
Yes: an F contributes 0 points, but its credits still sit in the denominator, which is why a single F drags a GPA down so hard. Whether your school replaces the grade after a retake is a policy question — enter only the attempt your school counts.
Yes. Enter finished semesters exactly as they are, then add the current semester with the grades you hope for, and adjust them until the cumulative figure reaches your target. That tells you precisely what the term requires. If the grades it demands look impossible, the honest lever is more credits at a strong grade next term, not hope.
Convert each percentage to its letter equivalent using your school’s chart first, then enter the letters. A weighted 5.0 scale is a different system; this calculator deliberately sticks to the standard unweighted 4.0 so results stay comparable.
