Inspiration

This single page app is inspired by the example Mr.Lynch raised in the very begining of chapter three of his bestseller One Up on Wall Street. And the number set Mr.Lynch use in the example is also the default values in this app, feel free to play with it and have a feeling of The Magic of Compounding Interest.

For people haven't read the book, I will quote part of the example below, and I do recommend buying the book if you havn't already.

Consider the Indians of Manhattan, who in 1626 sold all the real estate to a group of immigrants for $24 in trinkets and beads. For 362 years the Indian have been the subjects of cruel jokes because of it-but it turns out they may have made a better deal than the buyers who got the island. At 8 percent interest on $24 compounder over all those years, the Indians would have built up a net worth just short of $30 trillion, while the latest tax records from the Borough of Manhattan show the real estate to be worth only $28.1 billion. Give Manhattan the benefit of the doubt: that $28.1 billion is the assessed value, and for all anybody knows it may be worth twice that on the open market. So Manhattan's worth $56.2 billion. Either way, the Indian could be ahead by $29 trillion and change. (One Up on Wall Street, 2000, p.67)
