## The Rule of 70: Doubling Your Investment

When it comes to investing, one of the most important things to consider is how long it will take for your investment to double. This is where the rule of 70 comes in. The rule of 70 is a simple calculation that can help you determine how long it will take for your investment to double based on its growth rate.

### What is the Rule of 70?

The rule of 70 is a mathematical formula used to determine the number of years it takes for a variable to double by dividing the number 70 by the variable’s growth rate. This rule is generally used to determine how long it would take for an investment to double given the annual rate of return.

For example, if your investment has a growth rate of 7%, you can use the rule of 70 to determine that it will take approximately 10 years for your investment to double (70 ÷ 7 = 10).

### Why is the Rule of 70 Important?

The rule of 70 is important because it can help you make informed investment decisions. By understanding how long it will take for your investment to double, you can determine whether it is worth investing in or not. If your investment has a low growth rate, it may take a long time for it to double, which may not be worth the investment. On the other hand, if your investment has a high growth rate, it may be worth investing in, as it will double in a shorter amount of time.

### How to Use the Rule of 70

Using the rule of 70 is simple. All you need to do is divide the number 70 by the growth rate of your investment. The result will be the number of years it will take for your investment to double.

For example, if your investment has a growth rate of 5%, you can use the rule of 70 to determine that it will take approximately 14 years for your investment to double (70 ÷ 5 = 14).

It is important to note that the rule of 70 is not a perfect calculation and should be used as a rough estimate. It assumes that the growth rate of your investment will remain constant over time, which may not always be the case. However, it is still a useful tool for making informed investment decisions.

### Final Thoughts

The rule of 70 is a simple yet powerful tool for investors. By understanding how long it will take for your investment to double, you can make informed decisions about whether to invest or not. Remember, the rule of 70 is just an estimate and should not be relied upon as the only factor in your investment decision-making process. Always do your research and consult with a financial advisor before making any investment decisions.

## In Conclusion

The rule of 70 is a useful tool for investors to determine how long it will take for their investment to double based on its growth rate. By dividing the number 70 by the growth rate, investors can get a rough estimate of how long it will take for their investment to double. While the rule of 70 should not be relied upon as the only factor in investment decision-making, it is still a useful tool for making informed decisions.
