Compounding Interest – The Magic and Power

Imagine a job offer for work lasting exactly 31
days. You are given the choice of a flat payment of $474,836.47, or a daily wage
starting with 1 penny on the first day, and then doubling each day. This would
be 2 cents the second day, 4 cents for the third day, and so on through 31 days.
Which would you choose? If you were to take the
$474,000, you have just
thrown away an incredible $21,000,000 - that's 21
million dollars! |

The reason this works is because within a few days you
are no longer doubling pennies, but dollars, then
doubling thousands of dollars. Every day you are
doubling a bigger and bigger number (doubling your money
is called making 100%).
How much you earn because of compounding depends on the
percent you make and the amount of time the money grows.
Of the two (percent and time), time is the more
powerful.
If you bought stock in a company at $20 per share and it
went up in value starting at only 28 cents a week (1.4%
per week), with compounding you would be making 100% on
your investment each year and the stock price each year
would be doubling. Then in 31 years, every penny that
you had invested in this stock would turn into
$10,737,418. Every dollar invested would turn into
$1,073,741,824. Yes, really! Other "Why Invest Money?" Topics:
