There's a good chance that looking forward to retirement, when you won't have to punch a clock, give a PowerPoint presentation, teach a class, answer customer service calls, insert catheters, or plaster over drywall. But if you're just looking forward to it while not preparing for it, you may be setting yourself up for a lot of trouble.

These important retirement tables can serve as a good wake-up call for you -- or for anyone you care about, if you share them.

Some important retirement tables

Before we get to the most important retirement table, here are some other also-important tables. Let's start with an alarming one. It shows how much workers in the U.S. have socked away for retirement, per the 2023 Retirement Confidence Survey.

Less than $1,000

$1,000 to $9,999

See? Very alarming. Clearly, you'll need some kind of nest egg when you retire, as Social Security is far from sufficient for most people. Here -- see what you might receive from Social Security now, if you were retired.

Average retirement benefit for spouses of retired workers

I included spousal Social Security benefits because they're available to spouses with little or no benefits of their own -- and they can even be available to ex-spouses.

By this time, you may be worried about whether you'll be short of funds in retirement, and wondering whether you're saving enough. You might be wondering how to invest so that you'll likely grow your money at a respectable clip, while not taking on too much risk. To address that question, check out the table below. It shows the returns of various asset classes between 1802 and 2021, per Wharton Business School professor Jeremy Siegel.

The lesson is that over long periods, stocks have outperformed just about any other kind of investment. (Money that you'll need within shorter periods, such as less than five or even 10 years, shouldn't be in stocks, lest the market swoon just before you plan to sell.)

Fortunately, you don't have to become a stock market genius in order to build wealth powerfully with it. You can simply plow a lot of money into low-fee index funds over many years. Index funds can be all you need -- along with a lot of patience and perseverance, of course.

Here are some index funds to consider:

  • iShares Core S&P 500 ETF (NYSEMKT: IVV)
  • SPDR S&P 500 ETF (NYSEMKT: SPY)
  • Vanguard Total Stock Market ETF (NYSEMKT: VTI)
  • Vanguard Total World Stock ETF (NYSEMKT: VT)
  • Vanguard Growth ETF (NYSEMKT: VUG)

The most important retirement table

You may well be thinking that you need to build a bigger nest egg, and that you should do so by investing your long-term dollars in one or more index funds. Great! It's time to unveil what I think is the most important retirement table, below. It shows how much you might amass over time if you average 8% annually.

The table is powerful, because it shows what people like you and me can amass, if we're diligent about saving and investing over a long time. (I chose an 8% growth rate because the stock market has averaged annual returns of close to 10% over many decades, but it could be more or less than that over your particular period.)

The table should give you hope that you can amass more than you might have thought -- as long as you have a bunch of years before you retire. (If you don't have that many years and you haven't saved enough for retirement, there are still actions you can take to better your financial condition.)

So start thinking about your retirement right now -- even if you're only, say, 35. Think about what kind of retirement income you'll want to have and how you'll get it. Don't put off dealing with retirement, as it can be 30 or even 40 years of your life!
