What are the benefits of investing to IRA/Roth IRA, 401(k) in comparison to investing in long term CDs?
First, you need to understand the difference in discussing types of investments and types of accounts. Certificate of Deposits (CDs), money market accounts, mutual funds, and stocks are all examples of types of investments. 401(k), IRA, Roth IRA, and taxable accounts are all examples of types of accounts. In general, those are separate decisions to make.  You can invest in any type of investment inside any type of account.  So your question really has two different parts:   Tax-advantaged retirement accounts vs. Standard taxable accounts FDIC-insured CDs vs. at-risk investments (such as stock mutual funds) Retirement accounts are special accounts allowed by the federal government that allow you to delay (or, in some cases, completely avoid) paying taxes on your investment.  The trade-off for these accounts is that, in general, you cannot access any of the money that you put into these accounts until you get to retirement age without paying a steep penalty.  These accounts exist to encourage citizens to save for their own retirement.  Examples of retirement accounts include 401(k) and IRAs. Standard taxable accounts have no tax advantages, but no restrictions, either.  You can put money in and take money out whenever you like.  However, anything that your investment earns is taxable each year. Inside any of these accounts, you can invest in FDIC-insured bank accounts, such as savings accounts or CDs, or you can invest in any number of non-insured investments, including money market accounts, bonds, mutual funds, stocks, precious metals, etc. Something you need to understand about investing in general is that your potential returns are directly related to the amount of risk that you take on.  Investing in an insured investment, which is guaranteed by the government to never lose its value, will result in the lowest potential investment returns that you can get. Interest-bearing savings accounts are currently paying less than 1% interest.  A CD will get you a slightly higher interest rate in exchange for you agreeing not to withdraw your money for a period of time. However, it takes a long time for your investments to grow with these investments.  If you are earning 1%, it takes 72 years for your investment to double. If you are willing to take some risk, you can earn much more with your investments.  Bonds are often considered quite safe; with a bond, you loan money to a government or corporation, and they pay you back with interest.  The risk comes from the possibility that the government or corporation won't pay you back, so it is important to choose a bond from an entity that you trust. Stocks are shares in for-profit companies.  Your potential investment gain is unlimited, but it is risky, as stocks can go down in value, and companies can close.  However, it is important to note that if you take the largest 500 stocks together (S&P 500), the average value has consistently gone up over the long term.  In the last 35 years, this average value has gone up about 11%.  At this rate, your investment would double in less than 7 years. To avoid the risk of picking a losing stock, you can invest in a mutual fund, which is a collection of stocks, bonds, or other investments.  The idea is that you can, with one investment, invest in many stocks, essentially earning the average performance of all the stocks.  There is still risk, as the market can be down as a whole, but you are insulated from any one stock being bad because you are diversified. If you are investing for something in the long-term future, such as retirement, stock mutual funds provide a good rate of return at an acceptably-low level of risk, in my opinion. For the period 1950 to 2009, if you adjust the S&P 500 for inflation and account for dividends, the average annual return comes out to exactly 7.0%. Source. Currently inflation is around 2%.  So your 2% APY is a 0% real return where the stock market return is 7%.  I.e. on average, stocks have a return that is higher by 7.   If you mix in bonds, 70% stocks to 30% bonds, your real returns will drop to around 5.5%, but you are safer in individual years (bonds often have good years when stocks have bad years).   We're making a bit of a false dichotomy here.  We're talking about returns on stocks in retirement accounts versus returns on CDs in regular accounts.  You can buy stocks in regular accounts and it is legally possible to have a CD in a retirement account.  So you can get bankruptcy protection and tax advantages with a CD.
"Early this year I wrote an article Are you 401(k)o’ed?  I described the data from a 401(k) expense survey and the punchline was that the average large retirement plan (over 1000 participants) expense was 1.08%, and for smaller plans it rose to 1.24%.  As I commented below, if one's goal is to make deposits with income that avoid a tax of 25%, and hope to withdraw it at retirement at 15%, it doesn't take long for a 1% fee to completely negate the benefit of pretax savings.  These numbers are averages, in the same article, I mention (ok, I brag) that my company plan has an S&P fund that costs .05%. That's 1% over 20 years.  The sound bite of ""deposit to the match"" needs to be followed by ""depending on the choice of investments and their expenses"" within the 401(k).  Every answer here has added excellent points, fennec's last sentence shouldn't be ignored, there's a phaseout for IRA deductibility, and another for Roth eligibility. For Married filing joint, IRA deduction starts to be lost at $92K, and Roth deposit disallowed at $173K. This adds a bit to the complexity of the decision, but doesn't change the implication of the 1%+ 401(k) fees." You might be confusing two different things. An advantage of investing over a long term is the compounding of returns.  Those returns can be interest, dividends, or capital gains.  The mix between them depends on what you invest it and how you invest in it.  This advantage applies whether your investment is in a taxable brokerage account or in a tax-advantaged 401K or IRA.  So, start investing early so that you have longer for this compounding of returns to happen. The second thing is the tax deferral you get from 401(k) or IRAs.  If you invest in a ordinary taxable account, then you have to pay taxes on your interest and dividends for the year in which they occur.  You also have to pay taxes on any capital gains which you realize during the year.  These yearly tax payments are then money that you don't get the benefit of compounding on.  With 401(k) and IRAs, you don't have to pay taxes during these intermediate years. "To answer the first part of your question: yes, I've done that!  I did even a bit more.  I once had a job that I wasn't sure I'd keep and the economy wasn't great either.  In case my next employer wouldn't let me contribute to a 401(k) from day one, and because I didn't want to underfund my retirement and be stuck with a higher tax bill - I ""front-loaded"" my 401(k) contributions to be maxed out before the end of the year.  (The contribution limits were lower than $16,500/year back then :-)) As for the reduced cash flow - you need of course a ""buffer"" account containing several months worth of living expenses to afford maxing out or ""front-loading"" 401(k) contributions.  You should be paying your bills out of such buffer account and not out of each paycheck.  As for the reduced cash flow - I think large-scale 401(k)/IRA contributions can crowd out other long-term saving  priorities such as saving for a house down payment and the trade-off between them is a real concern.  (If they're crowding out basic and discretionary consumer expenses, that's a totally different kind of problem, which you don't seem to have, which is great :-)) So about the trade-off between large-scale 401(k) contributions and saving for the down payment.  I'd say maxing out 401(k) can foster the savings culture that will eventually pay its dividends.  If, after several years of maxing out your 401(k) you decide that saving for the house is the top priority, you'll see money flow to the money-market account marked for the down payment at a substantial monthly rate, thanks to that savings culture. As for the increasing future earnings - no.  Most people I've known for a long time, if they saved 20% when they made $20K/year, they continued to save 20% or more when they later made $100K/year.  People who spent the entire paycheck while making $50K/year, always say, if only I got a raise to $60K/year, I'd save a few thousand.  But they eventually graduate to $100K/year and still spend the entire paycheck.  It's all about your savings culture. On the second part of your question - yes, Roth is a great tool, especially if you believe that the future tax rates will be higher (to fix the long-term budget deficits).  So, contributing to 401(k) to maximize the match, then max out Roth, as others suggested, is a great advice.  After you've done that, see what else you can do: more 401(k), saving for the house, etc." The details of the 401(k) are critical to the decision. A high cost (the expenses charged within the) 401(k) - I would deposit only to the match, and I'd be sure to get the entire match offered. In which case, that $3000 might be good to have available if you start out with a tight budget.  Low cost 401(k) w/match - a no-brainer, deposit what you can afford. Roth 401(k) w/match - same rules for expenses apply, with the added note to use Roth when getting started and in a lower bracket.  Yes, it makes sense to have both.  You should note, depositing to the Roth now is riskless. The account, not the investment. If you decide next year you didn't want it, you can withdraw the deposit with no penalty or tax. Edit to respond to updated question - there are two pieces to the Roth deposit issue. The deposit itself, which puts the $3000 earned income into tax sheltered account, and the choice to invest. These two are sequential and you can take your time in between. I'm not sure what you mean by the dividend timing. In an IRA or 401(k) the dividend isn't taxed, so it's a non-issue. In a cash account, you might quickly have a small tax issue, but this doesn't come into the picture in the tax deferred accounts. You're ignoring the fact that you still had the taxes from the $5500 (so $1375) left over when making the traditional IRA contribution.  So yes, the Roth IRA grew without further taxing more than the Traditional IRA did; but you could've just as easily invested that $1375 in the same investments. While you'd owe taxes on them, true, you'd still earn a boatload of money.  That's another $10,607 you've earned, not tax-free, but with gains at the 15% CGR is still $9170.  So you now have $60,627 in the Roth, available tax-free, or you have $60,627 available at a 10% or so average rate (12% if you like, though I think you'll find it's more like 10%).   Say $53351, plus $9170 from the not-sheltered income after taxes, for $62,521 after taxes. So you make about $2000 more by using the traditional IRA for $5500 and then just investing the rest in a long term account.  The math might be slightly worse if you invest in something that has regular dividend taxes due, but if you're careful to use tax-favored investments you should be okay, and even if you don't you'll still end up ahead in the end if you make the same exact investment as your tax-sheltered account. Ultimately the question is: are you paying more in taxes now, or later, comparing now marginal rate to later average rate.  If you are paying more in taxes now, then traditional IRA plus invest the rest unsheltered.  If you're paying more later, then Roth IRA. I was in a similar situation with my now 6 year old.  So I'll share what I chose.  Like you, I was already funding a 529. So I opened a custodial brokerage account with Fidelity and chose to invest in very low expense index fund ETFs which are sponsored by Fidelity, so there are no commissions.  The index funds have a low turnover as well, so they tend to be minimal on capital gains. As mentioned in the other answer, CDs aren't paying anything right now.  And given your long time to grow, investing in the stock market is a decent bet. However, I would steer clear of any insurance products.  They tend to be heavy on fees and low on returns.  Insurance is for insuring something not for investing. "To keep it simple, I will keep the focus between a Trad IRA and a normal Taxable account (Roth's and 401(k) add more complications that make another problem).  I will also assume, based on the question, that you aren't able to deduct the IRA contributions. Also, a Roth is better in every way than a non-deductible Trad IRA so the ""backdoor Roth"" mentioned in other answers is probably the way to go and this is more of an academic exercise.  Ok, so why bother with the IRA if you're taxed anyway?  Because you aren't taxed as you go! With a normal non-tax-advantaged account you have to pay taxes every year on any realized capital gains and dividends (including fund distributions). Because of the compounding nature of savings, delaying paying taxes is in your best interest.  Simple example:  Taxable Account: IRA Account: Now, this is a very simplified example. If you're more tax-conscious (i.e. more buy-and-holding), you can delay paying some of the long-term cap gains in the taxable account, but any short-term cap gains (including distributions from the underlying funds) will be at your marginal income tax rate.  A few other observations: EDIT: I set up a spreadsheet where each year I deposited $1000 for 35 years. Each year, the balance in the IRA account grows by 5%, but the taxable only by 5%*(1-0.15) = 4.25% due to the effect of taxes. At the end of 35 years, my simulation assumes you pay 15% on all the gains in the IRA, which would likely not be the case, but easier than forecasting through retirement and demonstrates what I'm trying to show. Here's plot showing the balance in the various accounts, the blue is the IRA account, orange the taxable account, and grey is the effective balance of the IRA, after paying taxes on the gains:   And here's a plot of the advantage of the IRA (after paying taxes on the gains), vs the taxable account:  Whether that's worth it to you or anyone depends on some the assumptions in the simulation, especially effective tax rates, and growth rates, as well as any personal issues. Some people may be less likely to raid an IRA account, for example, than a normal account. Conversely, if you have a project coming up, you may need something a bit more liquid than an IRA." Frequently people saving money for a down payment, or for their emergency fund, feel that they need to find a way to speedup the process via methods that will generate more interest than a bank account or a CD. Once they have reached their goal they also feel that having the money sitting around not generating income is a missed opportunity. All investments that aren't 100% safe introduce risk. To entice you to invest they offer the opportunity make more money than a bank account or CD. But the downside is that the extra money isn't guaranteed. In fact the introduced risk also opens up the investment to the possibility of losses, including a total loss. You have identified risks with bank accounts and CDs. With the bank account you will generally lose money vs. inflation. With a CD the investment is less liquid if you sell early, or you want/need to sell 1/2 a CD, you will give up some of that extra income. Also if rates on a CD rise next month you are stilled locked into your current rate til the CD ends. Putting some or all of the money you are saving for the house into a risky investment means that you may shorten or extend the time period. Nobody knows.  by investing in real estate we can offset the risk of real estate   going up in the next couple years: if real estate goes up we will   still be able to use our down payment for a comparable house as of   now. Inversely, if real estate goes down we will lose on the down   payment but be able to get a house cheaper. Unless the REIT matches the market of residential real estate in your city/metropolitan region there is no guarantee that home prices in your city will move the same way the REIT does.  A recent listing of the 10 largest holdings of the index is: none of these tell me what home prices in my neighborhood will do next year.
