<prompt> Human: Hey everyone, Im relatively new to the idea of retirement as Ive just graduated college and found my first professional career. I was going over the benefits with my employer and they offer a 401k retirement plan, which doesnt sound bad at all. While doing some research on the differences between a 401k and a Roth IRA, a, perhaps trivial but, nagging question came to mind:If someone makes a hefty salary, say 200,000 a year, what would the benefit be towards investing in both a 401k and a traditional IRA? This person wouldnt qualify for a Roth IRA and the idea of tax deferment doesnt really apply between a 401k and a traditional IRA like it would between a 401k and a Roth IRA. A traditional IRA has a lower ceiling for investment than a 401k per year so, unless if you really wanted to horde cash for retirement, wouldnt just investing in a 401k be good enough?I guess at the point of making 200,000 a year, retirement may not be very important if this person was at least somewhat frugal with their money. But, for the sake of the question, lets assume that this person wants just enough money to retire for 20 or so years and hasnt really put much into hisher savings account.Thanks in advance, guys!  <response>: The first step in performing a Backdoor Roth IRA is contributing to a traditional IRA.
