You just started working, but it's never too early to dream about when you can quit -- for good. Here's your guide to making it happen. By Erin Burt, Contributing Editor July 3, 2008 I often dream about quitting my job.Don't get me wrong. I love what I do, and I haven't been doing it that long -- I'm still in my twenties, after all. I know I have many years of work ahead of me. But I don't want to work forever, so I've already set a plan in motion to make my escape.

Retirement may be decades away, but all of us, no matter our job or how many rich relatives we have, can secure a comfortable future. The trick is to start now, in our twenties, while time is on our side. No pain, much gain Even if you're not sure yet how you want to spend your retirement, start raising the money now. Doing so gives yourself the freedom to dream as big as you want, so your lack of funds can't hold you back. Advertisement Plus, the earlier you get going, the fewer sacrifices you'll have to make to save the money. I've said it before, and I'll say it again (and again, and again): Small contributions saved over a long time add up to big bucks! It's not hard if you begin young. Say, for example, a 22-year-old gets his first job out of college and starts saving $200 per month. If he earns an average 10% annual return on his money, by age 65 he'd have $1.5 million, and it took minimal -- if any -- financial sacrifice. If he added a mere $67 per month on top of that, he'd be sitting on a cool $2 million in retirement. Consider now that he didn't start staving until age 35. He'd have to scrape up $721 per month for the next 30 years to get $1.5 million, and $962 per month for $2 million. That may be doable, but it will probably require big cutbacks elsewhere in his life, especially if he's starting to save cold turkey. Make saving a habit while you're young and you won't miss the money when it's gone. (Think you don't have enough money to start saving?

Advertisement 401(k) vs. IRA Your first stop for retirement savings is your workplace 401(k) if your employer offers a match on your contributions, such as 50-cents for every dollar. That's free money, baby, and you shouldn't pass it up. The 401(k) is named for a section of the tax code, but underneath its nerdy exterior, it's one smooth operator that'll help make your retirement dreams come true. (The 401(k) is also known as a 403(b) or 457 plan, depending on where you work.) Basically, with a 401(k), your employer presents you with a list of pre-selected mutual funds. You choose which ones you want to invest in and tell your employer how much money you'd like to contribute each pay period. Then, those contributions are automatically taken out of your paycheck before taxes. (You get a tax break now, but you'll pay taxes on the money when you withdraw in retirement.) And if your employer offers a match on your money, it also is kicked in. More employers are offering a choice between a traditional 401(k) and a Roth 401(k). In this case, go for the Roth. Your contributions with a Roth are taken out after taxes, so you won't get the tax break now. But withdrawals from a Roth 401(k) are tax-free in retirement -- when you will almost certainly be in a higher bracket. Translation: The Roth 401(k) is the better deal for most young adults. Advertisement If your employer doesn't match 401(k) contributions or offer a Roth 401(k), you would be better off maxing out a Roth IRA outside the workplace first, and then saving in your 401(k). As with a Roth 401(k), withdrawals from a Roth IRA are tax-free in retirement. (See Why You Need a Roth IRA to learn more.) How much, and where? How much, exactly, should you save? The IRS won't allow you to set aside more than $15,500 in your 401(k) and $5,000 in your Roth IRA for 2008. Within those limits, the amount you save is up to you. Check your budget to figure out how much you can realistically save each month. Make sure you have room to set aside some money in a savings account for an emergency fund. Once your needs -- and a few wants -- are taken care of, it makes good sense to save as much as you can in your tax-sheltered retirement accounts. With a 401(k) and Roth IRA, you are in charge of choosing your investments, so pick wisely. Most employer plans offer a variety of mutual funds, which are also great investments for your Roth IRA (see A Beginning Investor's Best Friend). Advertisement At this point, the majority of your portfolio should be in stock funds, which offer the most potential for growth. Start out with a diversified stock fund -- one that invests in a broad range of stock types -- so you're not putting all your eggs in one basket. So, for example, a mutual fund that mirrors the performance of the overall stock market is a good place to start (such as Fidelity Spartan Total Market Index). A fund of funds can provide good diversification (such as T. Rowe Price Spectrum Growth). And so-called target funds are also fine choices (T. Rowe Price, Fidelity and Vanguard each offer good selections). Note of caution: Don't overload on your company's stock in your 401(k). If your employer goes under, you'd not only lose your job but also a good chunk of your retirement savings. As your account balance grows, you can branch out your investments if you desire.
