      Compound interest when charged by lenders

      Today “compound interest” usually relates to reinvested dividends and amortized growth/appreciation of investments (e.g., stocks, bonds) simply because non-predatory loans are designed for payoff within some fixed term. So if the term “compound interest” applies, something unexpected is happening (e.g., default) and the loan will be bundled and sold at a discount to collections.

      Not far enough back to make a difference I’d wager

      I’ll take that wager! $5k daily, or $15283 monthly, compounding quarterly, ignoring inflation, at 10% annualized ROI:
      … in 100 years becomes ~86 billion
      … in 200 years becomes ~1,817,426 billion
      … in 300 years becomes ~38,406,599,775 billion
      … in 533 years becomes ~8.11624 x 1023

      If that sounds incredible to you, you’re not alone. It’s the result of a hyperbolic growth curve that starts slow but keeps accelerating indefinitely, and 533 years is a very long time in market term, so you easily reach the silly-numbers range.
