Rule Of 70 | What Does the Rule of 70 Tell You?: An investment or your money might double in 70 years if you follow the rule of 70. Using this you may estimate how long. It will take your money to double in value at a certain rate of return. There are a number of ways this rule can be applied. When comparing investments with various yearly compound interest rates. Often known as doubling time. It can be applied to a wide range of situations.

### ​A Step-By-Step Guide To The Rule Of 70

Calculate the investment’s annual return or growth rate.

Therefore taking the annual rate of growth into account, divide 70 by the annual yield.

### What Can You Learn from The Rule Of 70?

Investors may use this rule to predict how much a certain investment will be worth in the future. Even though it’s a rough estimate.

Hence the formula is very accurate in calculating how many years it will take. For an investment for returning its double its original value.

Mutual fund returns and retirement portfolio growth rates. That can both be evaluated using this statistic by investors. Suppose a portfolio doubles every 15 years.

As well as an investor wants it to double in 10 years. Therefore investor could make allocation changes to the portfolio to enhance the growth rate, for example.

The rule of 70 is widely acknowledged as a simple mathematical approach. For dealing with exponential growth issues. As an investment’s potential growth rate is being examined. Hence this term is most frequently used in connection therewith.

An estimate in years can be generated by dividing the number 70. By the predicted rate of growth. Or it can be return on investment in financial transactions.

### Other Uses Of The 70/20 Rule

The rule of 70 may also used to estimate. How long it would take a country’s actual gross domestic product (GDP) to double. Hence we might use GDP growth as the rule’s divisor.

Same as we do when calculating compound interest rates. For example, if some country’s growth rate is 10%. The forecasts that country’s real GDP will be double in seven years, or 70/10.

### Real Growth VS. The Rule Of 70

Hence always keep in mind that this. It is merely a best guess based on expected growth. Original calculations may be incorrect if growth rates alter.

There were an estimated 161 million people living in the United States back in 1953. That number grew to 321 million by 2015. 1.66 percent was the growth rate in 1953.

The population would have doubled by 1995, according to the rule. As a result, the calculation was incorrect. As of variations in growth rate.

Compounding interest and exponential growth can be tricky to cope with. But the formula might provide some direction.

Using this method, you can apply it to any instrument that is predicted. To develop steadily over time, such as population. However, when the growth rate is expected to fluctuate significantly. The rule does not work well.
