A weighted GPA gives harder classes extra grade points so that taking them does not pull your GPA down. On the most common convention an A is worth 4.5 in an Honors class and 5.0 in an AP or IB class, which is why weighted GPAs are said to be on a 5.0 scale.
It is a convention, not a standard. Some schools use +1.0 for Honors too, some weight only AP, some weight only junior and senior years, and some do not weight at all. Use your school's values.
Five 1-credit classes: AP Calculus A (4.0 + 1.0 = 5.0), Honors English B+ (3.3 + 0.5 = 3.8), Spanish III A- (3.7), Chemistry B (3.0) and AP World History A- (3.7 + 1.0 = 4.7).
Weighted GPA = (5.0 + 3.8 + 3.7 + 3.0 + 4.7) / 5 = 20.2 / 5 = 4.04. Unweighted GPA = (4.0 + 3.3 + 3.7 + 3.0 + 3.7) / 5 = 17.7 / 5 = 3.54.
The half-point gap is the two AP classes and one Honors class at work: (1.0 + 1.0 + 0.5) / 5 = 0.5.
Add the bonus for each Honors or AP/IB class to that class's grade points (commonly +0.5 and +1.0), multiply by credits, add them up and divide by total credits.
It depends on how many weighted classes your school offers. Above 4.0 means you have taken weighted classes and done well in them; compare yourself with your school's own profile rather than a national number.
Not on the common +1.0 convention, where an A in AP is the maximum 5.0. Schools that give more than +1.0, or count A+ above 4.0, can produce higher numbers.
Many schools weight dual enrollment like AP (+1.0), which is how this calculator treats the AP/IB level, but some do not weight it at all. Check your handbook.
Both appear on applications, but many colleges recalculate an unweighted GPA from academic classes and look at the rigor of your schedule separately.
