AP/IB Impact Calculator — Weighted vs Unweighted GPA Impact

Advanced coursework can change how your transcript reads to you—and sometimes to colleges—but only within the rules your school sets. This calculator helps you compare a weighted GPA (where AP/IB or honors may earn extra points) with an unweighted GPA (typically capped at 4.0 for A work).

Use it when choosing next year’s schedule, estimating scholarship eligibility, or explaining rigor on applications. Remember: many colleges recalculate GPA internally, so treat this as a planning aid aligned with your local scale, not a universal “admissions GPA.”

If your school uses half-point honors weights or caps the number of weighted classes, mirror those choices in your entries so the side-by-side comparison stays realistic.

Quick Answer:

AP and IB courses often use a 5.0 scale (A = 5.0) while regular courses use 4.0. Weighted GPA includes that boost; unweighted caps at 4.0. Add your courses and mark which are AP/IB to compare both GPAs side by side.

About AP/IB Weighting

AP Courses

  • • Advanced Placement courses
  • • Typically weighted +1.0 point
  • • A grade becomes 5.0 instead of 4.0
  • • Recognized by most colleges

IB Courses

  • • International Baccalaureate courses
  • • Typically weighted +1.0 point
  • • Higher Level (HL) courses weighted more
  • • Globally recognized program

Note: Weighting policies vary by school. Some schools use +0.5 or +1.5 point scales. Check with your school's policy for exact weighting.

How it works

Weighted GPA assigns higher point values to designated advanced courses before averaging by credits. Unweighted GPA maps letter grades to a standard scale without boosts. The calculator applies the inputs you provide; it does not know your district’s rounding or weight caps unless you reflect them in the data.
