The
Exponential Growth Behind Money Investments
WHO WILL BECOME
A MILLIONAIRE
ACTIVITY
If you have
the self discipline to put your money in a savings account, or in
a CD, (certificate of deposit), or in a municipal bond, or
even in stocks, and then to keep it there for several years, you
can let the power of exponential growth make you wealthy.
You almost have
to run the numbers before you believe it though. Remember, the
longer you leave it in, the richer you get.
It's a lot like
the "doing
dishes" scenario where you trick someone into paying you
2 cents on the first day of dish washing and then 4 cents on the
second day and 8 cents on the third day etc.. It's a power of two
problem. Each day you make two times more. So the formula for money
made on any given day is just 2^(days worked).
It seems at
first that you aren't making much money, but if you stick it out,
on the tenth day you will make 2^10=1024
cents, and that is the same as $10.24.
Now on the next
day you make 2^11=2048 cents, or $20.48.
And on the twelfth
day you will make 2^12=4096 cents,
or $40.96.
By the fifteenth
day you make 2^15=32768 cents, or $327.68.
COOL HUH! It's
almost unbelievable.
Let's say you
kept this up for a month. On the last day of the month, you will
make 2^30=1073741824 cents. That's
equal to $10,737,418.24!!!! Almost
eleven MILLION dollars made in one day!
Now this same
idea is behind money investments. The key to remember here is that,
the longer you leave it in, the richer you get.
Let's take a
look at some examples:
You invest
$324 in a regular savings account at 3% and let the
interest sit there, (this is known as compounding your
interest), for 5 years.
The way
you figure out the value of your account at the end of five
years is like this:
value
= (initial amount invested)(1+your percentage rate written
as a decimal)^(number of years invested)
Click HERE to see how we
get this formula.
=$375.60.
The value
after 10 years of investment is,
=$435.42.
The value
after 30 years of investment is,
=$786.43.
You can
see here it takes quite a few years to double your money if
you have it invested in a regular savings account. Plus remember,
taxes will have to be paid on all the interest that accumulates
each year.
|
Now
if you take the same amount $324, and buy a CD at say
6% your money will grow faster.
The
formula is the same, only the percentage rate is different.
In
five years it looks like this,
=$433.58
In
10 years it looks like this,
=$580.23
And
in 30 years you will have this,
=$1,860.89.
Notice
that the 6% rate yields more than twice as much value as the
3%. This is why people are always shopping for the highest
interest rates they can find when investing their money.
Remember
of course with CD's you still have to pay tax on the interest
you make.
*Some municipal
bonds will give you the same kind of rates as a CD, but the
interest is NOT taxable.
|
Now
when investing money in the stock market, you can earn
very high percentage yields, but the reason is that there
is a certain amount of RISK too. You can also LOSE a
high percentage of your money or even all of it if the companies
you invest in go out of business.
In
general, people who invest in stocks buy them in several different
companies to help guard themselves from this risk. If one
company is doing poorly, the others will usually make up for
it.
Let's
take that same $324 and invest it in stocks which yield an
average increase in value of 15%.
In
5 years it looks like this,
=$651.67.
In
10 years it looks like this,
=$1,310.76.
In
30 years you have this,
=$21,452.61.
It's
amazing how big your $324 gets when invested for a long time
at a high percentage rate.
Remember,
here again, when you sell your stocks and realize all that
gained money, the gain is TAXABLE.
