The 'Rule of 72' is a simple formula used to estimate the time it takes for an investment to double in value based on a fixed annual rate of return. By dividing 72 by the annual interest rate (expressed as a percentage), investors can quickly gauge the approximate number of years required for their investment to grow twofold. For example, if the rate of return is 6%, it would take about 12 years for the investment to double (72 ÷ 6 = 12). This rule provides a quick mental calculation for evaluating investment growth.
How long it will take for your money to double/divide the annual interest rate into 72.
the number of years it takes for your money to double can be estomated by dividing 72 by the annual percentage interest rate.
Benjamin Franklin came up with this equation.
The Rule of 72 is a simple formula used to estimate the number of years required to double an investment at a fixed annual rate of return. The formula states that you divide 72 by the annual interest rate (expressed as a whole number). For example, if the interest rate is 6%, you would calculate 72 ÷ 6 = 12 years to double your investment. This rule provides a quick approximation and is most accurate for interest rates between 6% and 10%.
The Rule of 72 is a simple formula used to estimate the number of years required to double an investment based on a fixed annual rate of return. To use it, divide 72 by the expected annual interest rate (expressed as a whole number). For example, if your investment earns 6% annually, it would take approximately 72 ÷ 6 = 12 years to double your money. This rule provides a quick and easy way to gauge the impact of compound interest on investments.

How long it will take for your money to double/divide the annual interest rate into 72.
About 18 years.
As a general rule.....72 hours.
The best definition for 72 is the number before 73 and after 71.
Rule of seventy two is used to ascertain the period by which an investment would grow by 100%. 72 divided by rate of interest would provide the approximate period by which the investment would become double. As an example, if the rate of interest is 6% per month, the investment would be doubled in ( 72/6) 12 months. Rule of 72 thus is an important tool to know the investment horizon.
The rule of 72 is a quick and very accurate method of determining how long it takes for money to double at a specified rate of interest, compounded annually. For example, using the rule of 72 with a compounded interest rate of 6% it would take 12 years to double your money (72 divided by 6). The precise amount of time it takes to double your money at 6% based on the actual computation of compounded interest is 11.9 years. The rule of 72 works very well unless the rate of interest exceeds 20% at which point the error rate starts to deviate substantially from the actual answer. The rule of 72 can also be used to figure out what rate of interest you need to double your money in a specified number of years. For example, if you want to double your money in 5 years, divide 72 by 5 and the interest rate needed is 14.4%.
The "Rule of 72" gives a good approximation of 72/4=18%.
the number of years it takes for your money to double can be estomated by dividing 72 by the annual percentage interest rate.
