The Eighth Wonder of the World: Compound Interest

Albert Einstein famously remarked: "Compound interest is the eighth wonder of the world. He who understands it, earns it; he who does not, pays it." Compound interest represents earning interest on top of previous interest, causing investment balances to grow exponentially rather than linearly over time.

Compounding Formula

The universal compound interest formula with periodic additions is:

A = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) - 1) ÷ (r/n)]

  • A: Future value of the investment.
  • P: Initial principal deposit.
  • PMT: Regular monthly/annual contribution.
  • r: Annual nominal interest rate (decimal).
  • n: Compounding frequency per year (12 for monthly, 4 for quarterly, 365 for daily).
  • t: Number of years the money is invested.
