Learn About Compound Interest

What is Compound Interest?

Compound interest is interest calculated on the initial principal plus all previously earned interest. Einstein called it "the eighth wonder of the world".

Mathematical Formula

A = P(1 + r/n)^(nt)

  • A = Final amount
  • P = Initial principal
  • r = Annual interest rate
  • n = Compounding frequency
  • t = Time in years

Power of Time

The earlier you start investing, the more time your money has to grow. A $1,000 investment at 7% annually becomes $7,612 in 30 years.

Regular Contributions

Consistent monthly contributions can significantly multiply your results. This strategy is known as "Dollar Cost Averaging".
