Grade Point Average (GPA) Calculator

Calculate your GPA from course grades and credit hours. Supports up to 4 courses.

Grade Point Average is a credit-weighted mean, not a plain average of your letter grades -- a 3-credit A counts more toward your GPA than a 1-credit A, because GPA is meant to reflect how much of your overall coursework each grade represents. This calculator computes it the standard way: it multiplies each course's Grade -- on the standard 4.0 scale, where 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=0.0 -- by that course's Credits to get quality points, adds the quality points across all courses you enter, and divides by Total Credits. Total Grade Points is that intermediate sum shown on its own, and Total Credits is the sum of every course's credit hours -- both are provided so you can check the arithmetic or carry them forward into a cumulative GPA calculation across semesters. Because it's a weighted average, raising a course's Grade raises your overall GPA in proportion to that course's share of your Total Credits -- so it always helps as long as the course carries credit hours, and a course entered with 0 credits has no effect on your GPA at all no matter what grade you give it. What changing a course's Credits does is different and depends on context: adding credit hours to a course pulls the overall GPA toward that course's own grade, so it only raises your GPA if that course's grade is already above your current average, and lowers it if the grade is below average -- a 3.0 course carrying more credits pulls a 3.55 GPA down, not up. If every course you enter has 0 credits, Grade Point Average shows a dash rather than 0.000 -- a weighted average with no weight to divide by is undefined, not a straight-F 0.0. This calculator supports up to four courses at a time; for a full semester or a running cumulative total across terms, combine it with the College GPA Calculator.
