The Penny That Becomes $5.3 Million: Compound Interest Explained Visually

A plain-language walk through how compound interest actually works, using pictures instead of formulas: a staircase, a rolling snowball, a growing tree, and the classic doubling-penny example. Along the way it covers real numbers for savings accounts, the rule of 72, a small business reinvestment example, and how the same math works against you with credit card debt.
