How AP and IB weighting works

The standard weighting convention adds 1.0 grade point to every AP and IB course before doing the credit-hour math. An A (base 4.0) in AP Chemistry scores 5.0 weighted. A B+ (base 3.3) in IB History scores 4.3 weighted. Honors courses typically get +0.5 instead of the full +1.0.

The formula: add the appropriate bonus to the base grade points, multiply by credit hours, sum all courses, then divide by total credits. That gives the weighted GPA. The unweighted version runs the same math without any bonus.

IB weighting varies by school. Some IB programs weight only Higher Level (HL) courses at +1.0 and Standard Level (SL) courses at +0.5, the same as honors. Check your school's policy if you need a precise figure for official reporting.

The unweighted GPA calculator strips all bonuses so you can see the strict 4.0 figure colleges often use in their own recalculation.

FAQs

How is AP GPA calculated?

AP courses add 1.0 extra grade points to the base letter grade value. An A in an AP class earns 5.0 weighted grade points instead of the standard 4.0. That bonus is then multiplied by the credit hours for the course when computing the GPA average.

Does AP GPA go above 4.0?

Yes. A weighted GPA that includes AP or IB courses can exceed 4.0. A student with all AP classes and straight As could reach a weighted GPA of 5.0. This is why weighted and unweighted GPAs are always compared together.

Do IB and AP courses count the same for GPA?

In most US high school weighting systems, both AP and IB courses receive a +1.0 boost, making them equivalent for GPA purposes. The two programs differ in curriculum design and exam style, but the GPA bump is typically identical at schools that weight both.

Should I compare my AP GPA to others using weighted or unweighted?

Use unweighted GPA when comparing yourself to students at different schools with different weighting policies. Use weighted GPA when you want to highlight the rigor of your course load, especially in college applications where course selection gets its own evaluation.
