"Compound interest is the eighth wonder of the world. He who understands it, earns it... he who doesn't... pays it." - Albert Einstein

How Compound Interest Works

Compound interest is interest calculated on the initial principal, which also includes all of the accumulated interest from previous periods. It can be thought of as "interest on interest," and will make a sum grow at a faster rate than simple interest.

The Formula

A = P(1 + r/n)nt

Where:
A = Future Value
P = Principal Investment
r = Annual Interest Rate (decimal)
n = Number of times interest is compounded per year
t = Number of years

Tips for Maximizing Growth

  • 1

    Start Early

    Time is the most powerful factor in compounding. The earlier you start, the more time your money has to grow.

  • 2

    Increase Frequency

    More frequent compounding (e.g., monthly vs annually) results in higher returns over time.
