	Rule Of 72 - Financial Planner Site
		The Rule of 72 is a quick and easy ‘rule of thumb’ method for investors to work out how long it is likely to take for their invested money to double, given a constant rate of interest.
		The reason this is known as the Rule of 72 is that at an interest rate of 10%, your money is likely to double every 7.2 years.
		In the same way, the Rule of 72 can be used to forecast the timescale within which debts can be expected to double, given a particular interest rate.

	Rule of 72 - Wikipedia, the free encyclopedia
		In finance, the rule of 72, the rule of 70 and the rule of 69.3 all refer to a method for estimating an investment's doubling time, or halving time.
		These rules apply to exponential growth and decay respectively, and are therefore used for compound interest as opposed to simple interest calculations.
		The value 72 is also a convenient choice since it has so many small divisors: 2, 3, 4, 6, 8, 9, and 12.

		The purpose of this section is to provide an explanation of how to apply the Rule of 72 in order to make estimates of the time it will take for a given amount of money to double in value at a given interest rate.
		The Rule of 72 provides you a very easy method of estimating the number of years it takes for an investment's value to double at a specific interest rate or rate of return.
		The general formula is 72 = I x Y, where I is the interest rate and Y is the number of years needed to double your investment.

		The rule in this case is to divide 72 by number of years you would like it to take, and the Rule of 72 will give you an approximation to the rate of return required to double the starting amount.
		Again, the general rule is to divide 72 by the Cost of Living (COL) rate of increase, and the Rule of 72 will give you the approximate number of years required to halve the purchasing power of the starting amount.

	Rule Of 70 and Rule Of 72 Compared
		In finance, the Rule Of 72 is used in a similar fashion, except that you divide the rate into 72 rather than 70.
		In finance, the Rule Of 72 is probably used in preference to the Rule Of 70 as 72 has more whole number divisors (72, 36, 24, 18, 12, 9, and 8) than 70 (70, 35, 14, 10, and 7).
		Also, note that though the Rule Of 70 is always more accurate than the Rule Of 72 for negative growth (or shrinkage), it is always less accurate for negative growth than it is for positive growth.

	Rule 72(t)
		The rule requires that, in order for the IRA owner to take penalty-free early withdrawals, he or she must take at least five "substantially equal periodic payments" (SEPPs).
		Rule 72(t) allows you to take advantage of your retirement savings before the age of 59.5, when there is otherwise a 10% penalty on early withdrawal.
		The drawback to taking advantage of Rule 72(t) is that you may deplete your retirement accounts well before the end of your life expectancy.

		So in short, the rule of 72 doesn't give an exact answer, but for most common interest rates (say, in the 6-9 percent range,) it is accurate enough for most purposes.

	Duncan Williamson: The Rule of 72 rule72.html
		Please note, to save time and space, we are only discussing the rule of 72 in the context of an investment; but the method and mathematics are exactly the same when we deal with a loan.
		In fact, if we concentrate on the rates of interest from 1% to around 30%, the estimation errors are not that wild; and since we know that the rule of 72 only gives estimates, we have nothing to be afraid of, have we.
		Overall, the rule of 72 is a neat little trick that can be useful in situations where we might need to do some pretty quick calculations but when we might not be glued to our spreadsheet or our calculator.
