Why Is The Rule Of 70 Different From Compound Interest
For beginners, working of the rule of 70 can look familiar to working of compound interest. However, both the concepts are different from each other. To understand the difference between the rule of 70 and compound interest, it is important to look at both the terms individually.
Compound interest is a concept used for longer investment returns. It is calculated on a certain fixed value, also called principal amount. This principle amount is added on with an amount on the basis of interest rate. Compounding is referred to a technique of adding interest to the constantly growing amount in addition to the principal amount.
Investments with frequent compounding give a better rate of interest on the principal amount than less compounding. To study and use different rules of doubling your investment amount, compound interest is important. For the investors looking for earning interests without reinvesting, the time period taken to double the initial value will be more than double that of those who wish to reinvest.
On the other hand, for the rule of 70 to work, you need to keep the principal amount and rate of interest common. Only then will it give accurate and satisfactory results. Therefore, before applying any of the concepts, you need to look for your investment options and choices.
Limitations Of Rule Of 70

Also, another limitation of the rule is that you need a constant and correct annual interest rate to calculate the rule of 70. The formula is entirely dependent and applicable on a constant rate of interest.
With investments having varied interest rates over a time span, the rule proves to be inaccurate. Even the investments with different principal amounts, the rule of 70 will not work. It can be used for the investments to be made in a limited amount of time. In a limited amount of principle value with a constant rate of interest, the rule works well. Another limitation of the rule is you can not calculate the number of years it will need to gain a certain amount. It will only provide you the probably years in which your investment will double up.
Rule of 70 is a simple, effective, and efficient rule to calculate growth years of investments. For the investors looking for an easy way to calculate growth in years in which the principal amount will double itself with the current rate of interest, the rule of 70 is the one. It can be done without professional help or extraordinary knowledge of accounts. Investors can calculate doubling years using the rule of 70 on their own.
