GPA calculator, weighted and unweighted
Enter your grades once and get both numbers colleges care about, computed the standard way: 4.0 unweighted, plus honors and AP bonuses for the weighted read.

How it is computed
The scale, spelled out
Each letter grade maps to points on the 4.0 scale: A and A+ are 4.0, A- is 3.7, B+ is 3.3, B is 3.0, and so on down to F at 0.0. Your unweighted GPA is the credit-weighted average of those points. The weighted version adds 0.5 for honors courses and 1.0 for AP, IB, and dual-enrollment courses before averaging, which is the most common convention US high schools use.
Schools differ: some weight on a 6.0 scale, some give A+ a 4.3, some exclude non-academic courses. That is exactly why most colleges recalculate every applicant to one standard, and why the unweighted number plus your course list is the read that travels.

Common questions
GPA, answered
What is the difference between weighted and unweighted GPA?
Unweighted GPA grades every class on the same 4.0 scale, so an A is 4.0 whether the course is regular or AP. Weighted GPA adds a bonus for harder courses, typically +0.5 for honors and +1.0 for AP, IB, or dual enrollment, which is why weighted GPAs can pass 4.0.
Which GPA do colleges look at?
Most selective colleges recalculate your GPA their own way, often unweighted and sometimes academic-courses-only, and then read it next to your transcript for rigor. So the honest summary is: they look at your unweighted GPA and your course choices together, not your school's weighted number.
Is a 3.7 GPA good?
A 3.7 unweighted GPA is roughly an A-minus average, strong for the large majority of US colleges and within range at many selective ones, especially with a rigorous course load. At the most selective schools the admitted average sits near 3.9, so a 3.7 usually needs the rest of the application to carry more.
Do colleges see freshman year grades?
Almost all colleges receive your full transcript. A few systems, like the University of California, exclude 9th-grade grades from the GPA they compute, but they still see the courses. An upward trend across years genuinely helps.
What Spike does with this
Your GPA is one number. Spike reads the transcript behind it.
Spike learns the courses, trend, context, and goals behind the number, then turns the read into list strategy and next-semester priorities.
