<prompt> Human: So the only thing I understand about IRAs is that if I had a high tax exposure lets say 20 and I stick money into an IRA, and then when I retire I have a lower tax rate lets say 10 then I effectively get automatic savings of 550 for every 5500 I put in. Also if the IRA investments grow I might be able to get that money at that low tax rate. This seems to fall apart if I assume that I will have the same tax rate after retirement. So it seems to me that an IRA is a safe sort of gamble on the probability that when Im 60 years old I wont have much income and Ill be drawing a small amount from the IRA every year, keeping my tax exposure as low as possible to save a few thousand a year?Am I missing something? Are there any spreadsheets or graphs that clearly illustrate the benefit of tax deferment?Thanks!  <response>: If you are referring to Roth IRAs, they are a taxed advantaged account.Its better than personal investing because you are not taxed on any gains. With personal investing, you are taxed going in using post tax income and taxed when you pull out gains.
