Learn about Compound Interest — Simply Explained
Compound interest is earning interest on your interest — your money grows exponentially rather than linearly. Einstein allegedly called it the eighth wonder of the world. If you invest $1,000 at 10% annual return, you’d have $2,594 in 10 years and $17,449 in 30 years, even without adding another dollar.

What is the difference between simple and compound interest?+
Simple interest is calculated only on the original amount. Compound interest is calculated on the original amount plus accumulated interest. Over time, this difference becomes enormous.
What is the Rule of 72?+
Divide 72 by your interest rate to estimate how many years it takes to double your money. At 8% returns, your money doubles roughly every 9 years (72 / 8 = 9).
Why should I start investing early?+
Time is the most important factor in compound interest. Someone who invests $200/month from age 25–35 (10 years) can end up with more at 65 than someone who invests $200/month from age 35–65 (30 years).
