Weighted GPA Calculator
Account for Honors and AP/IB rigor with a weighted GPA on the common +0.5 / +1.0 scale.
How to calculate a weighted GPA
- Enter each course's grade and credit hours.
- Set each course level: Regular, Honors (+0.5), or AP/IB (+1.0).
- Read your weighted GPA on the boosted scale.
Frequently asked questions
How much do Honors and AP add to a weighted GPA?
On the most common scale, Honors courses add +0.5 and AP or IB courses add +1.0 to the grade points before averaging by credit hours. Scales vary by school, so confirm with yours.
What is the difference between weighted and unweighted GPA?
Unweighted GPA caps every course at 4.0. Weighted GPA raises the ceiling for harder courses, so a weighted GPA can exceed 4.0.
Sources and methodology
The weighted average is universal math, but the +0.5 Honors and +1.0 AP/IB boosts are a common example, not a universal policy. Use the weighting rules published by your school or district for an official GPA.
