Count how many A, B, C, D and F grades you have across every class, and get your flat unweighted GPA.
Estimate only, unweighted.
Unweighted high school GPA does not have plus or minus grades, and it does not care whether a class was AP Chemistry or study hall. Every A is worth exactly 4 points, no more, no matter how hard the class was:
Notice there is no A- or B+ row here. That is deliberate: this calculator mirrors the simplified letter-only report cards many high schools issue, which is a narrower scale than the plus-and-minus 4.0 scale colleges typically use. Neither one is more correct; they answer different questions.
The formula is straightforward: multiply each grade count by its point value, add the four products together, then divide by the total number of classes. GPA = (4 × A count + 3 × B count + 2 × C count + 1 × D count) ÷ total classes. There is no adjustment for course difficulty anywhere in that formula, which is exactly what "unweighted" means. An A in gym class and an A in AP Chemistry both contribute the same 4 points.
Colleges that recalculate applicants' GPAs on their own scale usually start from something close to this unweighted number, then apply their own rules about which courses to count and how much extra credit, if any, to give advanced classes. If your school's official transcript shows a higher number, it is very likely weighting AP, IB, or honors courses; the weighted GPA calculator on this site adds that layer back in with the standard honors and AP bonus points.
With the default counts loaded above, four A's, two B's, and one C, that is seven total classes. Points: (4 × 4) + (3 × 2) + (2 × 1) = 16 + 6 + 2 = 24. Divide 24 by 7 classes and the unweighted GPA comes out to 3.43. Add a single D to that same mix and the total climbs to eight classes with 25 points, dropping the GPA to 3.13, a reminder that one lower grade pulls harder on a small class count than it would on a large one.
Your school's official transcript likely weights AP, IB, or honors courses, adding extra points beyond the flat 4.0 scale this tool uses. This calculator gives you the unweighted figure only; use the weighted GPA calculator to add those bonuses back in.
Yes, this tool treats every grade you enter equally regardless of what year it was earned. Some schools recalculate GPA using only certain years or only core academic courses for college applications; check your school counselor's process if you need that specific number.
Pull your grade report or transcript and count each letter grade line by line. A rough guess will give you a rough GPA; the arithmetic here is only as accurate as the counts you enter.
No. This tool only accepts whole letter grades (A, B, C, D, F) on purpose, since many high school report cards work that way. If your school does use plus and minus grades, the GPA calculator on this site has those options built in.
