Hi Toby,
"50% is just a number." The hell it is! This is a weaseling equivocation comparable to something that would come out of Washington. If a guy started with $1000 and compounded it 50% daily, within months he'd have Buffet and Soros working for him. In a year he'd probably buy out Bill Gates. In two years, he'd be working with figures equivalent to the national GDP.
According to my calculation, within 10 weeks (50 days), with $1000 as capital and 50% daily, he could buy the whole Microsoft, not just Bill gate. If he does that in one year? There would not be enough money in the world for his bank account, not just the US's national GDP.
Formula is quite simple: F = P(1+i)^n where F is future value, P is present value, i is interest rate (x100) and n is the period. You can do the same with Excel, using function FV(rate, nper, pmt, pv, type)
But why bother with a 15-years old?
