What is weighted GPA?
Weighted GPA adds extra grade-point value for selected advanced courses. A common approach gives a smaller bonus to honors classes and a larger bonus to AP, IB or similarly advanced classes, but schools are free to define their own systems.
Weighted GPA vs. unweighted GPA
The calculator reports both. Unweighted GPA uses only base grade points from the letter grades. Weighted GPA adds the selected course-level bonus before multiplying by credits. Comparing both can show how advanced-course weighting changes the numerical average.
Why use custom weighting?
There is no single national weighted-GPA formula. Some schools cap the result, some use different bonuses, and others weight only specific courses. The custom option lets you match the basic bonus arithmetic more closely, but official transcript rules can still include additional details.
Weighted GPA formula
For each course, the calculator adds the level bonus to base grade points, multiplies by course credits, totals the weighted grade points, and divides by total credits. Regular courses receive no bonus.
