Rule Of 72
Once upon a time an Overseas Filipino Worker (OFW) started working abroad. At the age of 29 he had already saved a total of P 100,000.00 (Philippine peso)
Because the only mode of investment he knew about was to put his money in the bank, he placed his P 100,000.00 in the bank. Of course, the bank manager was delighted when he opened the account. He even recommended that the money be placed in a time deposit account in order that it would yield 4 % per annum, a much more higher interest rate than an ordinary savings account.
As suggested by the bank manager, he placed his money in the time deposit account and didn’t touch it until he reached the age of 65. Since he is retiring from his job, he went back to the bank to withdraw the P 100,000.00 in his time deposit account. To his amazement his P100,000.00 had already become P 400,000.00. Because he wanted to enjoy his life, he withdrew all his money and lived happily ever after.
Do you think this is a “live happily ever after”? Has this OFW “wisely” handled his money? Are you sure he is maximizing the full potential of his money or has somebody become more richer because of his ignorance ?
To fully understand this, take note of the Rule of 72. In order to know how many years it takes for your money to double you only need to follow this rule which is simply stated as follows: 72 / interest = No. of years it takes for your money to double
For this certain OFW, his money will double every 18 years. This is simply solved by applying the rule of 72 which is computed as follows: 72 divided 4 % per annum = 18 years. This means that if you add 18 years from the time he deposited his money, the P 100,000.00 will double to P 200,000.00 when he reaches the age of 47. After 18 more years when he reaches the age of 65, his money will already become P 400,000.00.
Now that the P 100,000.00 is in the bank’s hand, what do they do with it ? Well they basically invest it in other vehicles of investments which gives them a higher interest rate such as mutual funds, the stock market, the money market, government bonds, corporate bonds etc. They even use it to loan it back to the depositors at a much more higher interest rate. But let’s just say that all of the bank’s investing activities gave a return of 12 % per annum. Using the rule of 72, it can be determined that the same amount of money will double every 6 years. (computed as follows: 72 divided by 12 % interest = 6 years)
So when the OFW went back to the bank after 36 years and claimed his P 100,000.00 the bank manager gladly gave him back his P 100,000.00 plus the interest of P 300,000 amounting to P 400,000.00. After all they already made P 6 million pesos out of the OFW’s P 100,000.00. Now isn’t that hi-way robbery?
