Saving/ Investing a lump sum
In my mind, when looking at a five year period you have a number of options. You didn't specify where you are based, which admittedly makes it harder, to give you good advice. If you are looking for an investment that can achieve large gains, equities are impossible to ignore. By investing in an index fund or other diverse asset forms (such as mutual funds), your risk is relatively minimal. However there has historically been five year periods where you would lose/flatline your money. If this was to be the case you would likely be better off waiting more than five years to buy a house, which would be frustrating. When markets rebound, they often do it hard. If you are in a major economy, taking something like the top 100 of your stock market is a safe bet, although admittedly you would have made terrible returns if you invested in the Polish markets. While they often achieve lower returns than equity investments, they are generally considered safer - especially government issued bonds. If you were willing to sacrifice returns for safety, you must always consider them.  This is an interesting new addition, and I can't comment on the state of it in the United States, however in Europe we have a number of platforms which do this. In the UK, for example you can achieve ~7.3% returns YoY using sites like Funding Circle. If you invest in a diverse range of businesses, you have minimal risk from and individual company not paying. Elsewhere in Europe (although not appropriate for me as everything I do is denominated in Sterling), you can secure 12% in places like Georgia, Poland, and Estonia. This is a very good rate and the platforms seem reputable, and 'guarantee' their loans. However unlike funding circle, they are for consumer loans. The risk profile in my mind is similar to that of equities, but it is hard to say. Whatever you do, you need to do your homework, and ensure that you can handle the level of risk offered by the investments you make. I haven't included things like Savings accounts in here, as the rates aren't worth bothering with. 5 years is very short term, and since you are sure you'll need the money, investing it into the markets should probably not be done. You can toss it in Ally bank for 1% or consider a 5 yr raise your rate CD A decent write-up on time horizons: http://www.investopedia.com/articles/investing/110813/using-time-horizons-investing.asp If you want to go the stock/bond route you can assess the benefits of using something like a vanguard target date fund, or a roboadvisor such as wealthfront or betterment. You need to assess whether you think you may move up your time horizon, say you want to buy a house in 4 years, or, if it is 5 years, are you ok with it being 6.5-7 if there is a market downturn.
Pension in this instance seems to mean pension income (as opposed to pension pot). This money would be determined by whatever assets are being invested in. It may be fixed, it may be variable. Completely dependant on the underlying investments. An annuity is a product. In simple terms, you hnd over a lump sum of cash and receive an agreed annual income until you die. The underlying investment required to reach that income level is not your concern, it's the provider's worry. So there is a hige mount of security to the retiree in having an annuity. The downside of annuities is that the level of income may be too low for your liking. For instance, £400/£10,000 would mean £400 for every £10,000 given to the provider. That's 4% and would take 25 years to break even (ignoring inflation, opportunity cost of investing yourself). Therefore, the gamble is whether you 'outlive' the deal. You could hand over £50,000 to a provider and drop dead a year later. Your £50k got you, say, £2k and then you popped your clogs. Provider wins. Or you could like 40 years after retiring and then you end up costing the provider £80k. You win. Best way to think of an annuity is a route to guaranteed, agreed income. To secure that guarantee, there's a price to pay - and that is, a lower income rate than you might like. Hope that was the kind of reply you were hoping for. If not, edit your OP and ask again. Chris. PS. The explanation on the link you provided is pretty dire. Very confusing use of the term 'pension' and even if that were better, the explanation is still bad due to vagueness. THis is much better: http://www.bbc.co.uk/news/business-26186361 "The specific ""State Pension"" plan you have linked to is provided by the government of the U.K. to workers resident there. More generally speaking, many countries provide some kind of basic worker's pension (or ""social security"") to residents.  In the United States, it is called (surprise!) ""Social Security"", and in Canada most of us call ours ""Canada Pension Plan"".  Such pensions are typically funded by payroll deductions distinct & separate from income tax deducted at source.  You can learn about the variety of social security programs around the world courtesy of the U.S. Social Security Administration's own survey. What those and many other government or state pensions have in common, and the term or concept that I think you are looking for, is that they are typically defined benefit type of plans.  A defined benefit or DB plan is where there is a promised (or ""defined"") benefit, i.e. a set lump sum amount (such as with a ""cash balance"" type of DB plan) or income per year in retirement (more typical). (Note: Defined benefit plans are not restricted to be offered by governments only. Many companies also offer DB plans to their employees, but DB plans in the private sector are becoming more rare due to the funding risk inherent in making such a long-term promise to employees.) Whereas a defined contribution or DC plan is one where employee and/or employer put money into a retirement account, the balance of which is invested in a selection of funds. Then, at retirement the resulting lump sum amount or annual income amounts (if the resulting balance is annuitized) are based on the performance of the investments selected. That is, with a DC plan, there is no promise of you getting either a set lump sum amount or a set amount of annual income at retirement!  The promise was up front, on how much money they would contribute.  So, the contributions are defined (often according to a matching contribution scheme), yet the resulting benefit itself is not defined (i.e. promised.) Summary: DB plans promise you the money (the benefit) you'll get at retirement. DC plans only promise you the money (the contributions) you get now." When you start investing makes a very large difference to the outcome, but that is on the time scale of what generation you were born into, not what week you choose to open your 401(k).  As you note in your last sentence, there is nothing that you can do about this, so there is no point in worrying about it. If you could successfully market time successfully, then that would make a difference even at smaller time scales.  But you probably can't, so there is no point in worrying about that either. As BrenBarn points out, your statement about not regaining their net worth until 2013 applies to someone who invested a lump sum at the 2007 peak, not to someone who invested continuously throughout.   By my calculation, if you started continuously investing in a broad market index at the peak (around Jun 4, 2007), you would have recovered your net worth (relative to investing in a safe instrument that merely kept up with inflation, a hard thing to find these days) around April 12, 2010.  I've done the computation on each business day because that is easier, so it might be slightly worse if do the periodic investment on each payday which is much more realist for a 401(k). (And of course if you need to preserve/recover you net worth in 3 years, you shouldn't be in stocks in the first place) I believe that the Wikipedia article is attempting to draw a difference between dollar cost averaging as a result of investing when money becomes available (i.e. 401k contributions from your paycheck) and spreading out a lump sum investment. For the former you want to continuously invest as the money becomes available following your predetermined plan for allocation. For the later it may be reasonable to consider the market as you decide how and the timing for investing. Investing is really about learning your own comfort level.  You will make money and lose money. You will make mistakes but you will also learn a great deal. First off, invest in your own financial knowledge, this doesn't require capital at all but a commitment. No one will watch or care for your own money better than yourself. Read books, and follow some companies in a Google Finance virtual portfolio. Track how they're doing over time - you can do this as a virtual portfolio without actually spending or losing money.  Have you ever invested before? What is your knowledge level? Investing long term is about trying to balance risk while reducing losses and trying not to get screwed along the way (by people).  My personal advice: Go to an independent financial planner, go to one that charges you per hour only. Financial planners that don't charge you hourly get paid in commissions. They will be biased to sell you what puts the most money in their pockets. Do not go to the banks investment people, they are employed by the banks who have sales and quota requirements to have you invest and push their own investment vehicles like mutual funds. Take $15k to the financial planner and see what they suggest. Keep the other $5K in something slow and boring and $1k under your mattress in actual cash as an emergency. While you're young, compound interest is the magic that will make that $25k increase hand over fist in time. But you need to have it consistently make money. I'm young too and more risk tolerant because I have time. While I get older I can start to scale back my risk because I'm nearing retirement and preserve instead of try to make returns. Here's how I think about money. There are only 3 categories / contexts (buckets) that my earned money falls into. Savings is my emergency fund. I keep 6 months of total expenses (expenses are anything in the consumption bucket). You can be as detailed as you want with this area but I tend to leave a fudge factor. In other words, if I estimate that I spend approximately $3,000 a month in consumption dollars then I'll save $3,500 times 6 in the bank. This money needs to be liquid. Some people use a HELOC, other people use their ROTH contributions. In any case, you need to put this money some place you can get access to it in case you go from accumulation (income exceed expenses) to decumulation mode (expenses exceed income). This money is distinct from consumption which I will cover in paragraph three. Investments are stocks, bonds, income producing real estate, small businesses, etc. These dollars require a strategy. The strategy can include some form of asset allocation but more importantly a timeline. These are the dollars that are working for you. Each dollar placed here will multiply over time. Once you put a dollar here it shouldn't be taken out unless there is some sort of catastrophe that your savings can't handle or your timeline has been achieved. Notice that rental real estate is included so liquidating stocks to purchase rental real estate is NOT considered removing investment dollars. Just reallocating based on your asset allocation. This bucket includes 401k's, IRAs, all tax-sheltered accounts, non-sheltered brokerage accounts, and rental real estate. In general your primary residence is not included in this bucket. Some people include the equity of their primary residence in the investment column but it can complicate the equation and I prefer to leave it out. The consumption bucket is the most important bucket and the one you spend the most time with. It requires a budget. This includes your $5 magazine and your $200 bottle of wine. Anything in this bucket is gone. You can recover a portion of it by selling it on ebay for $3 (these are earned dollars) but the original $5 is still considered spent. The reason your thought process in this area is distinct from the other two, the decisions made in this area will have the biggest impact on your personal finances. Warren Buffett was famous for skimping on haircuts because they are worth thousands of dollars down the road if they are invested instead. Remember this is a zero-sum game so every $1 not consumed is placed in one of the other buckets. Once your savings bucket is full every dollar not consumed is sent to investments. Remember to include everything that does not fit in the other two buckets. Most people forget their car insurance, life insurance, tax bill at the end of the year, accountant bill, etc. In conclusion, there are three buckets. Savings, which serve as your emergency bucket. This money should not be touched unless you switch from accumulation to decumulation. Investments, which are your dollars that are working for you over time. They require a strategy and a timeline. Consumption, which are your monthly expenses. These dollars keep you alive and contribute to your enjoyment. This is a short explanation of my use of money. It can get as complicated and detailed as you want it to be but as long as you tag your dollars correctly you'll be okay IMHO. HTH. In addition to what others have said, I think it is important to consider that government retirement assistance (whatever it is called in each instance) is basically a promise that can be revoked. I talked to a retired friend of mine just yesterday and we got onto that subject; she mentioned that when she was young, the promise was for 90% of one's pay, paid by the government after retiring. It is very different today. Yes, you can gamble that you won't need the saved money, and thus decide not to save anything. What then if you do end up needing the money you did not set aside, but rather spent? You are just now graduating college, and assuming of course that you get a decently-paying job, are likely going to have loads more money than you are used to. If you make an agreement with yourself to set aside even just 10-15% of the difference in income right from the start, that is going to grow into a pretty sizable nest egg by the time you approach retirement age. Then, you will have the option of continuing to work (maybe part-time) or quitting in a way you would not have had otherwise. Now I'm going to pull numbers out of thin air, but suppose that you currently have $1000/month net, before expenses, and can get a job that pays $1800/month net starting out. 10-15% of the difference means you'll be saving around $100/month for retirement. In 35 years, assuming no return on investment (pessimistic, but works if returns match inflation) and no pay rises, that will still be over $40K. That's somewhere on the order of $150/month added to your retirement income for 25 years. Multiply with whatever inflation rate you think is likely if you prefer nominal values. It becomes even more noticable if you save a significant fraction of the additional pay; if you save 1/3 of the additional money (note that you still effectively get a 50% raise compared to what you have been living on before), that gives you a net income of $1500/month instead of $1800 ($500/month more rather than $800/month more) which grows into about $110K in 35 years assuming no return on investment. Nearly $400 per month for 25 years. $100 per week is hardly chump change in retirement, and it is still quite realistic for most people to save 30% of the money they did not have before. You've never saved money?  Have you ever bought anything?  There probably was a small window of time that you had to pool some cash to buy something.    In my experience, if you make it more interesting by 'allocating money for specific purposes' you'll have better results than just arbitrarily saving for a rainy day.    Allocate your money for different things (ie- new car, emergency, travel, or starting a new business) by isolating your money into different places.  Ex- your new car allocation could be in a savings account at your bank.   Your emergency allocation can be in cash under your bed.   Your new business allocation could be in an investment vehicle like a stocks where it could potentially see significant gains by the time you are ready to use it.    The traditional concept of savings is gone.  There is very little money to be earned in a savings account and any gains will be most certainly wiped out by inflation anyway.  Allocate your money, allocate more with new income, and then use it to buy real things and fund new adventures when the time is right.
