Believe it or not, seniors fear running out of cash more than they fear dying.

And unfortunately, even retirees who have built a nest egg have good reason to be concerned - with the traditional approaches to retirement planning, income may no longer cover expenses. That means retirees are dipping into principal to make ends meet, setting up a race against time between dwindling investment balances and longer lifespans.

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

For example, 10-year Treasury bonds in the late 1990s 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.

While this yield reduction may not seem drastic, it adds up: for a $1 million investment in 10-year Treasuries, the rate drop means a difference in yield of 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 can retirees do? You could dramatically reduce your expenses, and go out on a limb hoping your Social Security benefits don't diminish. On the other hand, you could opt for an alternative investment that gives a steady, higher-rate income stream to supplant lessening bond yields.

Invest in Dividend Stocks

We feel that these dividend-paying equities - as long as they are from high-quality, low-risk issuers - can give retirement investors a smart option to replace low-yielding Treasury bonds (or other bonds).

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.

Donegal Group (DGICA - Free Report) is currently shelling out a dividend of $0.15 per share, with a dividend yield of 4.38%. This compares to the Insurance - Property and Casualty industry's yield of 1.42% and the S&P 500's yield of 1.95%. In terms of dividend growth, the company's current annualized dividend of $0.6 is up 1.75% from last year.

General Mills (GIS - Free Report) is paying out a dividend of 0.49 per share at the moment, with a dividend yield of 3.22% compared to the Food - Miscellaneous industry's yield of 0.29% and the S&P 500's yield. Taking a look at the company's dividend growth, its current annualized dividend of $1.96 is flat compared to last year.

Currently paying a dividend of 1.07 per share, Kimberly-Clark (KMB - Free Report) has a dividend yield of 3.08%. This is compared to the Consumer Products - Staples industry's yield of 0% and the S&P 500's current yield. Looking at dividend growth, the company's current annualized dividend of $4.28 is up 3.88% from last year.

But aren't stocks generally more risky than bonds?

Overall, that is true. But stocks are a broad class, and you can reduce the risks significantly by selecting high-quality dividend stocks that can generate regular, predictable income and can also decrease the volatility of your portfolio compared to the overall 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

Whether you select high-quality, low-fee funds or stocks, seeking the steady income of dividend-paying equities can potentially offer you a path to a better and more stress-free retirement.

Generating income is just one aspect of planning for a comfortable retirement.
