What is Rule 69 in investment?
What is the Rule of 69? The Rule of 69 is used to estimate the amount of time it will take for an investment to double, assuming continuously compounded interest. The calculation is to divide 69 by the rate of return for an investment and then add 0.35 to the result.
The Rule of 69 states that when a quantity grows at a constant annual rate, it will roughly double in size after approximately 69 divided by the growth rate.
The Rule of 69 is a simple calculation to estimate the time needed for an investment to double if you know the interest rate and if the interest is compound. For example, if a real estate investor can earn twenty percent on an investment, they divide 69 by the 20 percent return and add 0.35 to the result.
The Rule of 72 states that by dividing 72 by the annual interest rate, you can estimate the number of years required for an investment to double. The Rule of 69.3 is a more accurate formula for higher interest rates and is calculated by dividing 69.3 by the interest rate.
Prove the Rule of 69.3
This means that the time it takes for an investment to double in value when the interest is compounded continuously can be approximated by dividing 69.3 by the annual interest rate (expressed as a percentage). This proves the Rule of 69.3 for continuously compounded interest.
The Rule of 72 is a calculation that estimates the number of years it takes to double your money at a specified rate of return. If, for example, your account earns 4 percent, divide 72 by 4 to get the number of years it will take for your money to double. In this case, 18 years.
The website KnowYourMeme.com dives into the history of the infamous position. During the 1790s, this term began to be more popular and it appeared in the “whor*'s Catechisms” in France. The term was soixante-neuf (French for sixty-nine) and the term became more well known.
The main difference is that Rule of 72 considers simple compounding interest, whereas Rule of 69 considers continuous compounding interest. Additionally, the accuracy of Rule of 72 decreases with higher interest rates. However, you can use Rule of 69 for any interest rate.
Lower or higher rates outside of this range can be better predicted using an adjusted Rule of 71, 73 or 74, depending on how far they fall below or above the range. You generally add one to 72 for every three percentage point increase. So, a 15% rate of return would mean you use the Rule of 73.
An effective annual interest rate is the real return on a savings account or any interest-paying investment when the effects of compounding over time are taken into account. It also reflects the real percentage rate owed in interest on a loan, a credit card, or any other debt.
What is the rule of 69 vs 70 vs 72?
According to the rule of 72, you'll double your money in 24 years (72 / 3 = 24). According to the rule of 70, you'll double your money in about 23.3 years (70 / 3 = 23.3). But, the rule of 69 says that you'll double your money in 23 years (69 / 3 = 23).
In finance, the rule of 72, the rule of 70 and the rule of 69.3 are methods for estimating an investment's doubling time. The rule number (e.g., 72) is divided by the interest percentage per period (usually years) to obtain the approximate number of periods required for doubling.
The Rule of 72 is a quick, useful formula that is popularly used to estimate the number of years required to double the invested money at a given annual rate of return. Alternatively, it can compute the annual rate of compounded return from an investment, given how many years it will take to double the investment.
