DOUBLE YOUR MONEY WITH THE RULE OF 72 ðŸ“ˆ Independent Investor (Collaboration)  Summary and Q&A
TL;DR
The Rule of 72 is a powerful tool for understanding the doubling time of investments based on anticipated rates of return.
Questions & Answers
Q: What is the Rule of 72 and how does it work?
The Rule of 72 is a simple formula that helps estimate the time it takes for an investment to double. To calculate, divide 72 by the anticipated rate of return. For example, if the anticipated rate of return is 8%, it would take 9 years for the investment to double.
Q: Why is it important to aim for an 8% rate of return?
The minimum 8% rate of return helps to outpace inflation, which typically runs at around 2%. By achieving at least an 8% rate of return, investors can preserve the value of their money and experience more doubling cycles over their lifetime.
Q: Does the Rule of 72 work for all rates of return?
The Rule of 72 is most accurate for rates of return between 8% and 12%. Higher rates of return make the doubling time shorter, while lower rates of return make it longer.
Q: How does the choice of account or investment vehicle impact the outcome?
The choice between a zerofee account and a feebased managed account can have a significant impact on the final investment amount. Fees and management costs can erode the potential returns, resulting in a substantial difference over a longterm investment horizon.
