Debt management is a must if you want to be financial free.
To Albert Einstein is attributed these words: “The most powerful force in the universe is compound interest.” The rule of 72 is just a simple mathematical computation of compounded interest.
Although Einstein is best known for his theory of relativity, some declare that his discovery of the Rule of 72 is more important. Some skeptics however, declare that this rule had been known long before he was born. The majority nevertheless, believe that it was Einstein who popularized the rule.
One of the most basic rules that investors should know is the Rule of 72. This rule is used to determine how many years it would take for money to double.
It is very simple to do the math using the Rule of 72. Just divide 72 by the interest rate and it will equal to the number of years it will take your money to double. But the uses of this rule is not only limited to investments. It can also be used to manage your debts intelligently. The following is how the Rule of 72 can be also written: 72 / interest rate = number of years for your debt to double
If you use the equation above, you can easily determine how many years will it take for your debt (credit card, mortgage, loans etc.) to double.
Let us make a case in point using credit card interest rates. Most credit card companies here in the Philippines have 3.5% interest rate that amounts to 42% interest in a year. Now we divide 72 by 42 and the resulting answer will be the amount of years it takes for your credit card debt to double. (72 / 42 = 1.7 years or 20/4 months).
So how will this help you? Even if the information above is not as precise since you will probably be paying some of your credit card debt, however, our illustration shows just how much credit card debts grow so fast. Now knowing that your credit card debt doubles every 21 months, you will be more convinced to pay up your credit card debt as soon as possible.
