Put $100,000 into undervalued, dividend-paying stocks today. Through a combination of capital gains and reinvested yields, the market could turn that single lump sum into a $1 million fortune over the next 15 to 20 years.

While that's solid advice for any new investor, it can be hard to follow. First, $100,000 is not the kind of money most folks just have lying around. I know I don't. Second, which stocks would you invest that money in if you did? There are more than 3,000 dividend payers trading on the U.S. markets alone, and there's no way to tell at a glance which are good buys.

Fortunately, we can work around these limitations.

Invest more
There are fewer barriers to investing today than ever before. Opinions on stocks are a dime a dozen online, and discount brokerages make it possible to buy and sell shares for as little as a few dollars from the comfort of our own homes.

Those are wonderful developments for individuals who seek to build a secure financial future. You don't need $100,000 to start investing. You can start with as little as $350 -- the amount needed to keep commissions at 2% on a $7 trade. What kind of returns can you expect from such a small investment?

Good ones.

Constant consistency
Wharton finance professor Jeremy Siegel has demonstrated that it's reasonable to expect a real return of about 6.5%. That's what's known as Siegel's constant -- and as he told the Fool in a recent visit, he's pretty proud to have a constant named after him. Add inflation to that 6.5%, and you're looking at a nominal return of approximately 9%. Using the nominal rate, the stock market could deliver you a tidy $400,000 nest egg after 25 years of investing $350 each month. Not bad for only $105,000 of principal invested.

High yields and low prices
The key to earning that return -- as Siegel points out in his research -- is reinvesting dividends. And the power of those dividends can be profound.

According to Siegel, the best-performing stock through 2003 in the original S&P 500, which began in 1957, is Altria and its incredible 19.8% annualized return. Why has it done so well? Reinvested dividends.

Investor distaste for tobacco and fear of lawsuits has kept Altria's price depressed, while the company continued to pay out huge amounts of cash -- the yield today is 6.9%. That meant investors could reinvest their dividends at lower prices, thereby supercharging returns.

Today, given the volatility of the stock market, a number of stable dividend payers are on sale with better-than-market average (2%) yields. That includes ...

Company

Current Yield

Novartis (NYSE:NVS)

3.7%

Hershey (NYSE:HSY)

3.4%

Kraft (NYSE:KFT)

4%

3M (NYSE:MMM)

2.7%

SYSCO (NYSE:SYY)

3.6%

All of these companies boast solid yields -- yields that have dramatically increased since this stock market funk began. And if you're short on cash in today's market, buying healthy dividend payers like this and reinvesting their dividends quarterly is a great way to keep adding money during this down market, when valuations are so compelling.

The Foolish bottom line
The answer to the "Which stocks?" question, then, is easy: companies with above-average yields and below-average prices. Those are exactly the types of companies that our Fool dividend guru, James Early, focuses on in his Motley Fool Income Investor advisory service.
