How It Works
How AP Credits Save Money
Each AP exam with a qualifying score (usually 3 or higher) can earn college credit, letting you skip equivalent courses.
Formula
Credits Earned = Exams Passed x Credits per Exam
Net Savings = (Credits x Cost per Credit) - (Exams x Exam Fee)
AP credits can also shorten your time to degree by an entire semester or more, compounding the savings with room, board, and opportunity cost.
Worked Example
A student passes 4 AP exams worth 3 credits each, at a school charging $500/credit. Each exam costs $98.
- 01Credits earned: 4 x 3 = 12
- 02Tuition saved: 12 x $500 = $6,000
- 03Exam costs: 4 x $98 = $392
- 04Net savings: $6,000 - $392 = $5,608
