Italian Mathematician Luca Pacioli's Rule of 72
In 1494 the Italian Mathematician Luca Pacioli published "Summa de arithmetica, geometria, proportioni et proportoionalita" where he introduced the Rule of 72. Though this is the first known mention of the rule, it is likely that the rule was already in use prior to Luca referencing it. The rule or 72 did not become widely known until nearly a century later. Even Albert Einstein is known for saying "There is no force more powerful than compound interest" and he used this simple estimate to calculate how many years it would take for an investment to double in value, based on the rate of return (RoR) or the interest rate at which it grows. However, on the flip side, this calculation of 72 as an approximation can also be used to halve a value. For instance, 72 divided by the inflation rate, equals how many years it would take to halve your money. So if inflation goes up by 3% every year, then in approximately 24 years, your annual income would be worth half its current value. Meanwhile, if your investments are growing at a rate of 8%, then the money in the accounts is doubling in size every 9 years. To truly understand the effect of an account, you must first understand how the RoR affects the money within it. Knowing this now, which option below would you say is the most important, or the one that you would want to complete first? Things to Consider: How are you currently using an interest rate to work in your favor and grow your money? How are interest rates working against you in your life? Are you saving your money in a location that it is depreciating faster than it is growing due to inflation? What if there are options where you can double your money even faster that what you are currently doing? Would you want more information on those types of accounts?
