Here's a revealing data point: older Americans are scared more of outliving wealth than of death itself.

Also, retirees who have constructed a nest egg have valid justifications to be concerned, since the traditional ways to plan for retirement may mean income can no longer cover expenses. Some retirees are now tapping their principal to make a decent living, pressed for time between decreasing investment balances and longer life expectancy.

Your parents' retirement investing plan won't cut it today.

For example, 10-year Treasury bonds in the late 1990's offered a yield of around 6.50%, which translated to an income source you could count on. However, today's yield is much lower - currently under 2% and probably not a viable return option to fund typical retirements.

The impact of this rate decline is sizable: over 20 years, the difference in yield for a $1 million investment in 10-year Treasuries is more than $1 million.

Today's retirees are getting hit hard by reduced bond yields - and the Social Security picture isn't too rosy either. Right now and for the near future, Social Security benefits are still being paid, but it has been estimated that the Social Security funds will be depleted as soon as 2035.

So what's a retiree to do? You could cut your expenses to the bone, and take the risk that your Social Security checks don't shrink. Or you could find an alternative investment that provides a steady, higher-rate income stream to replace dwindling bond yields.

Invest in Dividend Stocks

As a replacement for low yielding Treasury bonds (and other bond options), we believe dividend-paying stocks from high quality companies offer low risk and stable, predictable income investors in retirement seek.

For example, AT&T and Coca-Cola are income stocks with attractive dividend yields of 3% or better. Look for stocks like this that have paid steady, increasing dividends for years (or decades), and have not cut their dividends even during recessions.

Going beyond those familiar names, you can find excellent dividend-paying stocks by following a few guidelines. Look for companies that pay a dividend yield of around 3%, with positive annual dividend growth. The growth rate is key to help combat the effects of inflation.

Here are three dividend-paying stocks retirees should consider for their nest egg portfolio.

Kimberly-Clark (KMB) is currently shelling out a dividend of $1.07 per share, with a dividend yield of 3.01%. This compares to the Consumer Products - Staples industry's yield of 0% and the S&P 500's yield of 1.96%. In terms of dividend growth, the company's current annualized dividend of $4.28 is up 3.88% from last year.

Sempra (SRE) is paying out a dividend of 1.04 per share at the moment, with a dividend yield of 3.59% compared to the Utility - Gas Distribution industry's yield of 3.43% and the S&P 500's yield. Taking a look at the company's dividend growth, its current annualized dividend of $4.18 is up 8.01% from last year.

Currently paying a dividend of 0.38 per share, Tsakos Energy (TNP) has a dividend yield of 6.65%. This is compared to the Transportation - Shipping industry's yield of 0% and the S&P 500's current yield. Looking at dividend growth, the company's current annualized dividend of $0.63 is flat compared to last year.

But aren't stocks generally more risky than bonds?

The fact is that stocks, as an asset class, carry more risk than bonds. To counterbalance this, invest in superior quality dividend stocks that not only can grow over time but more significantly, can also decrease your overall portfolio volatility with respect to the broader stock market.

A silver lining to owning dividend stocks for your retirement portfolio is that many companies, especially blue chip stocks, increase their dividends over time, helping offset the effects of inflation on your potential retirement income.

Thinking about dividend-focused mutual funds or ETFs? Watch out for fees.

If you're interested in investing in dividends, but are thinking about mutual funds or ETFs rather than stocks, beware of fees. Mutual funds and specialized ETFs may carry high fees, which could lower the overall gains you earn from dividends, undercutting your dividend income strategy. Be sure to look for funds with low fees if you decide on this approach.

Bottom Line

Regardless of whether you select high-quality, low-fee funds or stocks, looking for a steady stream of income from dividend-paying equities can potentially lead you to a solid and more peaceful retirement.
