GPA calculator
A 3.5 GPA is a B+ average. A 3.0 is a B. A 4.0 is straight As. The GPA scale (A=4.0, B=3.0, C=2.0, D=1.0, F=0) weights your grades by credit hours—a 3-credit A counts more than a 1-credit A. Cumulative GPA is the weighted average of all your classes.
Good to know
Credit hours matter more than you think. A 3-credit class counts three times as much as a 1-credit class. An A in a 4-credit class is worth more than an A in a 1-credit seminar. Strategically, this means: (a) don't slack in high-credit courses, and (b) if you're boosting GPA, focus on classes with more credits for more impact per grade.
Raising a low GPA takes time. If you have a 2.5 GPA after 60 credit hours and start getting 4.0 every semester, it takes 30+ more credit hours to reach 3.0 overall. Early grades have outsized impact because they set the baseline. A bad freshman year haunts you; a strong freshman year gives you cushion. GPA is cumulative and hard to move once you have lots of credits.
Weighted GPAs (honors/AP) are different. Many high schools use weighted scales where honors/AP classes give extra points (A = 4.5 or 5.0). Colleges often recalculate your GPA on a standard 4.0 scale to compare applicants fairly. Your high school transcript might show 4.3, but colleges see 3.9. This calculator uses standard 4.0 unweighted scale.
