Enter each course as grade,credits,type. Use AP or IB for advanced placement and international baccalaureate courses (+1.0), H for honors (+0.5), and R for regular (no boost). Weighted and unweighted GPA appear side by side.
Leave type blank or use R for any regular course.
Computed in your browser. AP and IB each add +1.0; honors adds +0.5.
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.
The unweighted GPA calculator strips all bonuses so you can see the strict 4.0 figure colleges often use in their own recalculation.
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.
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.
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.
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.
