How Compound Interest Works

Interest earns interest. Time does the heavy lifting.

  • 1

    Simple interest pays only on what you deposited. Compound interest pays on your deposits plus the interest already earned.

  • 2

    $1,000 at 5% compounding annually becomes about $1,629 in 10 years — with no extra deposits.

  • 3

    Starting five years earlier usually beats saving a larger amount later.
