High School GPA Calculator

Each letter grade has a point value. For an unweighted GPA, A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0 regardless of course difficulty. For a weighted GPA, honors courses add 0.5 to each grade point and AP or IB courses add 1.0, so an A in an AP class is worth 5.0 and a B in an honors class is worth 3.5. Add all the grade points and divide by the number of courses.

Unweighted GPA treats every course the same. An A is an A whether the class is regular, honors, or AP. Weighted GPA adds extra points for harder classes, which is why some students report GPAs above 4.0. Many schools and colleges look at both; admissions offices often recalculate to their own scale.

No. The 4.0 unweighted scale is common, but the boost for honors, AP, or IB varies. Some schools add only 0.5 for AP, others add 1.0. A few use a 100-point or 5.0 scale instead of 4.0. The values in this calculator follow the most common pattern: 0.5 for honors and 1.0 for AP or IB. Confirm your school's exact scale with your guidance counselor.

Yes. Course-difficulty boosts apply only to passing grades. An F in an AP class is still 0.0 and pulls down both your weighted and unweighted GPA the same amount.

There is no universal answer because admissions offices read GPA alongside course rigor, grades trend, and class rank. Unweighted, anything above 3.5 is generally considered competitive at selective colleges; above 4.0 weighted often signals advanced course load. Use your own school's grade distribution and your college list as the better benchmark.
