Weighted GPA Calculator Formula
The Weighted GPA Calculator formula calculates calculate weighted GPA with Honors and AP or IB bonus points, or an Australian WAM weighted by year level.
This formula is used because it connects the main inputs directly to the result people need.
It keeps the work clear, so you can change one value and see how the answer moves.
Weighted GPA recognises that an A in an AP, IB, or Honors course represents harder work than an A in a standard course. US high schools typically add 0.5 for Honors and 1.0 for AP or IB before averaging. Australian universities instead compute a WAM, where marks are weighted by both credit points and year level so later years count for more.
