Rule Of 72
December 19th, 2009
There was once an Overseas Filipino Worker (OFW) who worked abroad for several years. At the age of 29 his savings already amounted to 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.
So he placed his money in the time deposit account and waited until he reached the age of 65. At the age of 65 he went back to the bank and asked to withdraw the P 100,000.00 in his time deposit account. Lo and behold his P100,000.00 already became P 400,000.00 because of the interest. So he withdrew his money from the bank 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.
The bank on the other hand takes that P 100,000.00 and invests it at mutual funds, the stock market, the money market, government bonds, corporate bonds etc. averaging a 12 % return on the P 100,000.00 that the OFW placed under time deposit. Under the rule of 72, that same amount of money will double every 6 years. (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?
Think like the bank if you want to be more wealthy and a more better steward of your money ! The Rule of 72 works ! Make it work for you !
