Video transcript

Doubling an investment from $100K to $1 million can vary significantly based on the rate of return. For example, at a 10% annual return, it would take approximately 24 years using the rule of 72 (72 divided by the annual rate of return). Higher returns can shorten this period, while lower returns will extend it.

Questions and answers

What is the rule of 72 and how does it work?
The rule of 72 is a simple formula to estimate how many years it will take for an investment to double, by dividing 72 by the annual rate of return.
How long does it take to turn $100K into $1 million at different return rates?
At a 10% annual return, it takes about 24 years; higher returns reduce the time, while lower returns increase it.
Can I get rich quickly by investing with high returns?
Higher returns can speed up investment growth but usually come with higher risks. Consistent, moderate returns are generally safer for long-term growth.
