How To Get Rich Part 1

Wednesday, August 25th, 2010

Author Tony De Maio

Some folks consider me rich. I guess I am. I have enough money to allow me to lead my life without working. That doesn’t necessarily mean I have a lot of money, it may just mean I can live cheaply. There are two ways to be “rich”.

1) Have so much money you can do anything you wish; and,
2) Want so little that a small amount of money suffices for your needs and desires.

Folks have asked me how I “did it”. I reply it would take at least two hours to explain, and I don’t have that much time. It’s like going to a doctor and saying, “Doctor, I’ve got this growth on my arm, can you cure it?” The doctor looks at it, gives you a shot and says, “Come back in two weeks.” After two weeks, you return and the growth is gone. You query the doctor, “Hey, Doc, thanks. Can you show me how to do that?” The doctor naturally replies, “Do what?” You say, “Fix folks. I have a large family and lots of medical bills. Could you teach me medicine so I can do my own medicine? Maybe I can do it for a few others and make a few bucks.”

There are several replies to that question—the most obvious one is, “Sure, give me just a couple of hours of your time. But first, take 4 years of college–including mathematics, biology, anatomy, chemistry, and physiology; and another 4 years of medical school. Get 20 years of experience, and then come on back for a couple of hours.” Upon reflection, such a question is insulting. What it says is, “Tell me what you’ve learned in your education and experience in your life.” It is generally implied, “Do it in 10 minutes—I’m busy.”

I cannot tell you how to get rich in two hours. I can tell you how to go about learning how to get rich rather quickly—much as the above paragraph told you quite quickly how to go about becoming a doctor. You need some materials to get rich “my way”. You need a scientific calculator (one that can raise a number to a power) or spreadsheet software (excel, lotus, etc.), three books, and three formulas. The three books are on three different topics, and it would not hurt to get more than one book on each topic. You also need a plan. Probably the most difficult part of the process is constructing the plan.

Let us first consider the formulas needed.

First of all, you need to understand compounding. Einstein called compounding the “eighth wonder of the world.” There are three “compounding” formulas. The first is simple compounding. It involves raising a percentage to a power (multiplying it by itself) several times. For example, if you earn 10 percent interest, you would multiply the amount you have invested by 10% and add it to the principal. If you invested $200, you would multiply $200 by .10 (10%) to get $20, then add it to the $200 to get $220 that you would have after a year. This is mathematically equivalent to multiplying $200 by 1.10 (1 + .10). To get the amount you would have after TWO years, you would multiply the $220 by 1.10 AGAIN, to get $242. This would be mathematically equivalent to multiplying the initial $200 by 1.10 by 1.10—the order of multiplication makes no difference. Hence, you could multiply 1.10 by 1.10 to get 1.21, then multiply the 1.21 times $200 to get $2.42. Mathematically, we write this as: (“*” is multiplication; ^ is exponentiation—multiply the number by itself that many times.)

$200 * 1.10 * 1.10 = $200 * 1.10^2 = $200 * 1.21 = $242

(If you do not have the perseverance to go through that description until you understand it, you probably do not have the perseverance to become rich.)

Using that notation, we can compute compounding quite easily if we have a scientific calculator. We can use the calculator to determine how much money we would have for ANY number of time periods (usually years). To determine how much money we would have at the end of FIVE years, simply compute:

$200 * 1.10^5 = $200 * 1.61 = $322 (cents omitted)

Let us use this formula to solve a practical problem. Thirty-seven years ago, a friend borrowed $200 from me. Since I had to borrow the money on my credit card at 18%, the friend promised to pay me 18% interest until he paid it off. I haven’t seen this “friend” since I loaned him the money. How much does he owe me?

$200 * 1.18^37 = $91,340

which is a fairly impressive amount. Of course, had I INVESTED $200 at 18%, I would have had just as much. (Had I been a bit wiser, I might have invested $400—and had twice as much.)

Suppose we have a home and a thirty-year mortgage at 8%. If we were to pay $100 on the principal, how much money would be saved over the life of the loan? It’s the compounding formula:

$100 * (1 + .08)^30 = $100 * (1.08)^30 = $100 * 10.0627 = $1006.27

So if you pay $100 on your mortgage principal at the start (or put an extra $100 down), you will save over $1000 in interest over the life of the loan. Anyone who tells you that you should do this should be ignored. It is YOUR decision whether or not the $100 is better spent today for items you desire or need, or is better invested to save $1,000 over thirty years. Perhaps you should pay an extra $100 each month of the first year and save over $12,000 in interest over the life of the loan. Make that decision (and similar decisions) wisely. The single decision is not very important; the philosophy and the desire to be informed before making such decisions is very important.

The second formula is a bit more complicated, but easily used with a bit of practice and a scientific calculator. Mathematically, it is called an “annuity”, which means a string of payments made at equally spaced intervals over a time period. An example would be payments made monthly to a retirement plan over several years. Under such a payment schedule and a given fixed interest rate, how much money will accrue? The formula is:The formula is:

or $200 x 230 = $46,000. NOTE: It is very important to be aware of the time frame and interest factors. Note that the YEARLY interest is 12%, so the MONTHLY interest is 1%. Note that payments are made EACH MONTH for TEN YEARS, so 120 payments are made. It is quite easy to make a mistake and intermix months and years when using this formula. Note also that although you only “contributed” $24,000, you have almost twice that amount due to interest. Such is the nature of compounding.

Let us use this formula to solve a practical problem. When I was 15 years old, an insurance salesman sold my parents a $5,000 life insurance policy that will pay me $45/mo when I am 65. The policy cost $85/yr. How much would I have at 65 if I had invested that $85/yr at 10% for 50 years?

At this point, one can begin to address the question: “Is whole life insurance a good idea?” (Interestingly enough, $85 back then would have purchased about 42 cartons of cigarettes or 340 gallons of gasoline. Today, $45/mo is $540/yr, which would purchase about 15 cartons of cigarettes or about 210 gallons of gasoline. Sometimes more money is really less money—in purchasing power.)

The third formula needed is called the mortgage formula, or amortization formula. It involves the notion of making payments on an interest-bearing loan and answers the question of “How much am I REALLY paying.” When you purchase a car on credit and make payments, a certain amount of your payment is going to “service the loan” or to “interest”. The formula is:

Monthly payments would be found by dividing the (yearly) interest rate by 12 (.15/12 = .0125), and multiplying the time by 12 (months in a year) to get (3 * 12 = 36) so that:

Payment = .0125 * $1,200) / (1 – (1 + .0125)^-36) ) = $41.60

You may note that the total amount paid under the monthly payment plan is $41.60 * 36 or $1497, or about $300 more than the purchase price of what you purchased. That is “interest” or the “cost of the money”. It is not my intent to lecture you that you “wasted” $300 by making the immediate purchase. It IS my intent to lecture you that you should KNOW that you paid $300 more for the object. It is a personal decision as to whether the immediate possession of the object is worth the additional $300 as opposed to waiting and saving for it. Certainly if it is a vehicle you need to get to work, it may well be very worthwhile to pay the additional money in interest. If you are purchasing a house, it is unlikely that you will be able to save the purchase price for a very long time so you must borrow to purchase the home. It is my concern that you KNOW what you are paying for what you are buying. To those that say, “Just tell me what the payment is so I’ll know if I can afford it.” My reply is, “Good luck.”

  1. I have played with the top part compounding for years with every sceneriao I could imagine, based on past history. Too bad past history does not guarantee future returns, or being smart enough at a young age to compound with a secure product. The amount of time is so important.

    How much is the payment? the famous last words of a credit bubble.

    I remember using this formula eons ago to figure up how much I would need by age 30 so that I would have enough saved so that I could retire at age 50. lol Problem was I never got the rates of return that I needed consistantly and had failed investments/business plans. I dont think I have ever averaged over 8% return on anything past 1998. I remember I had CD’s in the mid 80′s for 5 years at 15% interest. lol ah well its just money.

  3. Folks,

    I sent corrections to Mike to clean up the formulas so they are readable.

    OMR,

    Too bad you didn’t buy a 30 year treasury at 15%. Such investments are possible–unfortunately apparently only in hindsight.

    MY mistake was not buying dividend stocks and going for capital gains. All I did was make the gubbermint happy.

    I recall buying Bank of America (400 shares) for about 6 bucks a share. I sold at $25 and was quite happy. It subsequently split several times. If I had held it, I would have had about 4,000 shares. My last dividend check (before things went to hell) would have been my TOTAL profit from the sale.

    STILL, for youse youngsters, take it for wot it’s werth. The second part (Part II) give a bit of advice on the topic.

    always,
    tony

    Tony,

    LOL indeed unfortunately I was 8 at the time lol

  5. I love to play with this stuff. I have spreadsheets set up to show the monthly payment schedule, monthly principle/interest and total amount of interest for my home mortgage, my husband’s car loan and revolving credit. According to my mortgage spreadsheet, I figure that if I could pay an extra $500 every month on my brand new (as of next Monday) 30-year mortgage, I could pay it off in less than 9.5 years and save about $91K in interest.

  6. Val,

    I suggest that if you save that $500/mo, you will soon (within 2 years) be able to GET more interest on it than you will save by paying it off.

    always,
    tony

  7. Tony,

    I ain’t so much a youngster, but am looking forward t part II, I can use all the good advise I can get. Or maybe I finally got old enough that I decided I need to listen.

  8. Tony,

    There’s probably no way I’ll be able to set aside an extra $500 anyway, but if I can, that’s an interesting thought. You’re probably right. Interest rates have no where to go but up, do they?

  9. Val,

    I sent you a private post. Please let me know if you got it. I’ll probably try and post it in about 2-3 weeks.

    In terms of interest rates going “up”, I agree. Matter of fact, I’ve agreed for several years. :) :) Wot’s the old joke?? The markets can stay irrational much longer than you can stay solvent.

    Steve,

    It’s a funny thing, but the older the “kids” get, the smarter the parents become in their eyes. I’m glad you think it’s “good advice”, since it’s the best I have.

    I was teaching a class once, and I sed,

    “A smart man learns from his mistakes; a wise man learns from the mistakes of others.”

    One of the “brighter” students asked, “What does THAT mean?”

    I sed, “Well let’s take an example. A smart man may take up smoking, and then decide that it isn’t good, so he will stop smoking. A WISE man wil look around, see all the folks smoking that can’t stop, do some reading, and not take it up in the first place.”

    The student sed, “Oh, I see what you mean. I talk to my parents about smoking all the time, but they won’t quit. Smoking is bad.”

    Hopefully, the other students got something out of my story.

    always,
    tony

    I’ve written in the past about investing outside the US. Today’s news seems to indicate writing off Brazil, which has been quite a success story. Good old government: They’ve decided that too many assets are foreign-owned, particularly agricultural lands, so they’re reviewing ALL property titles with the idea of annulling transactions. That will pretty much stop foreign investment in other sectors as well.

  11. Laughter, Desert Rat. I’m finishing up an article for W&G entitled, “Eet eez ze costom of ze contry, senyor.” Brazil just outlawed foreign ownership of property and is considering confiscating everything purchased back to 1988! Well…that’s what banana republics DO.

  12. Lovely article, Tony, and I like equations. Still, it’s amazing what oldtimers with math skills can do with a pencil, a legal pad, and no equations at all…

  13. Linda,

    Yep.

    I used the old mechanical rotary calculators back in the sixties. Before that, I used a slide rule. Bought my first electronic calculator (no exponent, no memory) for $139 in 1970. In today’s dollars, that’s about a thousand dollars. Today, I can buy much more power at discount stores for five bucks. Gots more power sitting on my desk than the 7090 IBM computer I learned on.

    Speaking of formulas, here’s the cleaned up version.

    compounding:

    amount * (1 + interest)^time were “time” in the number of
    time periods

    annunity:

    SHOULD READ

    PAYMENT * (1 + interest)^number -1
    ————————————————————————
    interest

    where “number” is the number of payments

    For example, suppose you make a $200 payment monthly into a savings account that pays 12% interest per year, and you make such payments for 10 years. How much will you have? (note: 12% PER YEAR is 1% PER MONTH; 10 years is 120 MONTHS)

    SHOULD READ

    200*(1 +. 01)^120-1 200*91.01^120-1 200 * (3.30 -1) $200 * 2.30
    ——————————————— = —————————— = ———————— = ———————————
    .01 .01 .01 .01

    or $200 x 230 = $46,000.

    Amortization:

    How much am I REALLY paying.” When you purchase a car on credit and make payments, a certain amount of your payment is going to “service the loan” or to “interest”. The formula is:

    SHOULD READ:

    interest * amount
    Payment = ————————————————————————
    1 – (1 + interest)^-time

    (note the negative exponent)

    For example, suppose you wish to purchase something that costs $1,200 at 15% interest over three years. The payment is computed as:

    SHOULD READ

    .15 * $1,200
    Payment = —————————————————
    1 – (1 + .15)^-3 (Again, note that the “3” is negative.)

    180 180
    Payment = —————————— = ———- = $525 a year
    1 – .657 .343

    You may note that the total amount paid under the monthly payment plan is $41.60 * 36 or $1497, or about $300 more than the purchase price of what you purchased. That is “interest” or the “cost of the money”.
