Strange but true: seniors fear death less than running out of money in retirement.

And retirees have good reason to be worried about making their assets last. People are living longer, so that money has to cover a longer period. Making matters worse, income generated using tried - and - true retirement planning approaches may not cover expenses these days. That means seniors must dip into principal to meet living expenses.

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

For many years, bonds or other fixed-income assets could produce the yield needed to provide solid income for retirement needs. However, these yields have dwindled over time: 10-year Treasury bond rates in the late 1990s were around 6.50%, but today, that rate is a thing of the past, with a slim likelihood of rates making a comeback in the foreseeable future.

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.

How can you avoid dipping into your principal when the investments you counted on in retirement aren't producing income? You can only cut your expenses so far, and the only other option is to find a different investment vehicle to generate income.

Invest in Dividend Stocks

As we see it, dividend-paying stocks from generally low-risk, top notch companies are a brilliant way to create steady and solid income streams to supplant low risk, low yielding Treasury and fixed-income alternatives.

Look for stocks that have paid steady, increasing dividends for years (or decades), and have not cut their dividends even during recessions.

A rule of thumb for finding solid income-producing stocks is to seek those that average 3% dividend yield, and positive yearly dividend growth. These stocks can help combat inflation by boosting dividends over time.

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

Consolidated Edison (ED Quick QuoteED - Free Report) is currently shelling out a dividend of $0.89 per share, with a dividend yield of 3.24%. This compares to the Utility - Electric Power industry's yield of 2.7% and the S&P 500's yield of 1.39%. The company's annualized dividend growth in the past year was 2.41%.

Currently paying a dividend of $0.61 per share, NatWest Group (NWG) has a dividend yield of 7.34%. This is compared to the Banks - Foreign industry's yield of 2.72% and the S&P 500's current yield. Annualized dividend growth for the company in the past year was 35.61%. Check NatWest Group dividend history here>>>

But aren't stocks generally more risky than bonds?

It is true that stocks, as an asset class, carry more risk than bonds, but high-quality dividend stocks not only have the ability to produce income growth over time but more importantly, can also reduce your overall portfolio volatility relative to the broader stock market.

An advantage of owning dividend stocks for your retirement nest egg is that numerous companies, particularly blue chip stocks, raise their dividends over time, helping alleviate the impact of inflation on your potential retirement income.

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

You may be thinking, "I like this dividend strategy, but instead of investing in individual stocks, I'm going to find a dividend-focused mutual fund or ETF." This approach can make sense, but be aware that some mutual funds and specialized ETFs carry high fees, which may reduce your dividend gains or income, and defeat the goal of this dividend investment approach. If you do wish to invest in a fund, do your research to find the best-quality dividend funds with the lowest fees.

Bottom Line

Pursuing a dividend investing strategy can help protect your retirement portfolio. Whether you choose to invest in stocks or through low-fee mutual funds or ETFs, this approach can potentially help you achieve a more secure and enjoyable retirement.
