Albert Einstein reportedly called compound interest the eighth wonder of the world. Whether he actually said it is debatable — but the mathematics are irrefutable. Compound interest is the single most powerful force in personal wealth creation.
Simple interest pays returns only on your original principal. Compound interest pays returns on your principal AND on the returns you have already earned. Consider two investors starting with $10,000: Investor A earns 8% simple interest and has $34,000 after 30 years. Investor B earns 8% compound interest and has $100,627 after 30 years. The same rate, the same starting amount, nearly three times the result.
The Rule of 72 is one of the most useful mental shortcuts in investing. Divide 72 by your expected annual return and you get the approximate number of years it takes to double your money. At 8% annual return, your money doubles every 9 years.
Starting early consistently outperforms investing more later. An investor who puts $5,000 per year from age 25 to 35 then stops will outperform an investor who puts $5,000 per year from age 35 to 65 — even though the first investor invested one-third as much money. Time in the market is the most powerful variable.
