How Compound Interest Works
Compound interest calculates interest on both the principal and previously accumulated interest—"interest on interest."
"Compound interest is the eighth wonder of the world. He who understands it, earns it; he who doesn't, pays it."
The Formula
P = Principal, r = Annual rate, n = Compounds per year, t = Time in years. More frequent compounding = higher returns.
