What are some limitations of the Rule of 72?

While the Rule of 72 is a useful tool, it’s important to remember that it’s only an estimate. It assumes that your investment will earn a consistent interest rate over time, which may not always be the case. Additionally, it doesn’t take into account any taxes or fees that may be associated with your investment. Finally, it’s important to remember that past performance is not a guarantee of future results, so the Rule of 72 should be used as a guideline rather than a guarantee.

By dividing 72 by the interest rate you hope to earn, you can get an approximate number of years it will take for your investment to grow.
