First, congrats on being debt-free soon! I sent my last check to Sallie Mae on November 1, 2010, and from that day forward, I would never owe another person anything ever again (except for a credit card balance that I pay in full each month). That day was a personal milestone for me, just as your “day” will be for you (if you stay debt-free).
I am 40 and retired early. Both my 401(k) and my Roth IRA played big roles in my personal finance plan because they are such powerful money-saving tools -- the 401(k) played the bigger role because the limits were much higher ($19,500 for a 401(k) and $6,000 for a Roth IRA this year, for example). Some years, my income was too high to contribute to a Roth IRA, but when it was available to me, I always maxed it out.
I have not started withdrawing from my 401(k) or Roth IRA yet, as I am currently living on cash reserves. When I need to, I’ll start withdrawing from the accounts, with special consideration for the fact that I am well below normal retirement age. There are strategies I can employ to avoid the associated penalties and taxes, though.
To answer your questions…
Do you have experience using either as your retirement? Yes. I have used both since my first real job in 2006. Both are still major components of my portfolio in retirement, second only to my taxable account.
How was it? Well, the answer to that question depends entirely on the market, but seeing as I have been investing seriously in both accounts since 2008 -- and we were in a gigantic, sustained bull market this whole time -- it has been phenomenal… until just recently, of course, but that will turn around, too, in time.
You get a huge tax break by using these tax-advantaged vehicles. There is zero disadvantage to using them, so why not use them? Every year I worked after grad school, I
maxed out both 401(k) and Roth IRA contributions, as long as I had access to those accounts. Both played a huge role in my Investment Policy Statement (IPS), along with a taxable account.
If you could go back and re-plan your retirement, what would you do? Make more money, save more money, and start earlier! If I had started saving and investing with purpose, starting with my first job as a busboy at the age of 15? I’d be twice as wealthy, probably. If I could go back and re-plan starting at age 34? I’d try to make more money (take higher-paying assignments) and sock more money away into the taxable account after maxing out my Roth IRA and/or 401(k).
If you are interested in a deeper understanding of Roth and other IRA’s, 401(k)’s, or any aspect of retirement planning, personal finance, managing debt, etc., I recommend downloading a free pamphlet called “If You Can” by Bill Bernstein and reading it through completely. Then, if you can (ba-da-bump), purchase the seven or so books (they can be purchased cheap and used or even borrowed from a library) in the reading list and go through the reading exercises. And if you read all that, you will understand every important aspect of personal finance better than 99% of professional financial advisors.
P.S. -- As I suspected, others were also not clear on whether you were asking about a Roth IRA vs. a 401(k) or a Roth 401(k) vs. a traditional 401(k). Those are very different questions, but in either case, there are excellent, professionally-produced information products online that can answer either of those questions with more accuracy and clarity than I can.
