A great Kos diary from commenter Upper West on Mitt Romney’s IRA:
What was your return on your IRA, Keogh or Pension Plan last year? For the last 15 years? For 1984-1999?
If you did great you made maybe 5 or 10 percent a year. If the period coincided with the Bull Market, maybe over 10 or 15 years you made 80-100 percent.(EDIT: 10 percent over 15 years is actually 320%.)
But no matter how well you did, you did not do as well as Mitt Romney between 1984 and 1999. Mitt was allowed to contribute a maximum of $32,000 per year to his IRA and other forms of retirement accounts. So in 15 years, he contributed no more than $480,000.
And yet that account is now worth $102,000,000![…]
Using simple calculations, that equals a return of 21,250% (twenty one thousand two hundred fifty percent!). (EDIT: About 27% per year.)
