# Why 0.35 is added in rule of 69? By Nick

### Quick Peek:

Looking to invest your money? The rule of 69 is a quick way to calculate how long it will take for your investment to double based on the rate of return. However, for a more precise outcome, add 0.35 to the result to account for the effect of compounding. Keep in mind that this rule should only be used as a rough estimate, and other factors can affect the rate of return and time it takes for an investment to double. So, do your research and consider all your options before making any decisions.

## Why 0.35 is added in rule of 69?

When it comes to investing, it’s important to understand the rate of return and how long it will take for your investment to double. This is where the rule of 69 comes in handy. The rule of 69 is a quick and easy way to calculate the number of years it will take for your investment to double, based on the rate of return.

The rule of 69 is simple: divide 69 by the rate of return, and the result is the number of years it will take for your investment to double. For example, if your rate of return is 5%, it will take approximately 14 years for your investment to double (69 / 5 = 13.8).

However, to get a more precise outcome, we should add 0.35 to the result. For example, if a person wants to invest in a bank FD (fixed deposit), which gives a rate of return of 5%, the amount will double in ((69 / 5) + 0.35) or 14.15 years.

### The Reason for Adding 0.35

The reason for adding 0.35 to the result is to account for the effect of compounding. Compounding is the process of earning interest on interest, which can significantly increase the value of your investment over time. By adding 0.35 to the result, we are accounting for the effect of compounding, which gives us a more accurate estimate of the time it will take for our investment to double.

It’s important to note that the rule of 69 is not a perfect calculation, and it should be used as a rough estimate. There are many factors that can affect the rate of return and the time it takes for an investment to double, such as inflation, taxes, and market fluctuations. However, the rule of 69 is a useful tool for investors to quickly estimate the time it will take for their investment to double.

### Conclusion

In conclusion, the rule of 69 is a quick and easy way to estimate the time it will take for your investment to double. By adding 0.35 to the result, we can get a more precise outcome that accounts for the effect of compounding. While the rule of 69 is not a perfect calculation, it’s a useful tool for investors to quickly estimate the time it will take for their investment to double. Keep in mind that there are many factors that can affect the rate of return and the time it takes for an investment to double, so it’s important to do your research and make informed investment decisions.
