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.

ap_exams_passed = 4credits_per_exam = 3cost_per_credit = 500ap_exam_fee = 98
  1. 01Credits earned: 4 x 3 = 12
  2. 02Tuition saved: 12 x $500 = $6,000
  3. 03Exam costs: 4 x $98 = $392
  4. 04Net savings: $6,000 - $392 = $5,608
