Compound Interest
Earning returns on your returns, so growth accelerates over time.
Compound interest is the engine of long-term wealth. Because each year’s gains earn their own gains, money grows in a curve that starts slow and bends sharply upward. The earlier you start, the more of your final balance comes from growth rather than your own contributions. Try our free calculator to see it.
For example
$300 a month at a 7% return grows to roughly $370,000 over 30 years, and most of that final number is growth, not the money you put in.
