Welcome to Investing Basics! If you’ve found your way here, chances are you’ve either got some money socked away or you’re planning to do so. But first things first. Why is investing a smart idea?

Simply put, you want to invest in order to create wealth. It’s relatively painless, and the rewards are plentiful. By investing in the stock market, you’ll have a lot more money for things like retirement, education, recreation — or you could pass on your riches to the next generation so that you become your family’s Most Cherished Ancestor. Whether you’re starting from scratch or have a few thousand dollars saved, Investing Basics will help get you going on the road to financial (and Foolish!) well-being.

Know your goals

What are you saving for? Retirement. College for the kids? A new speaker system complete with woofers and tweeters? An exotic animal menagerie complete with Chihuahuas (woofers) and canaries (tweeters)? A retirement villa in the sun-baked hills of Tuscany?

Say you take $2,000 of your savings and put it into the stock market. If your money returned 10% a year (the S&P 500’s historical average), two grand would be worth $34,898.80 after 30 years. That might not get you the perfect retirement home, but it’ll at least give you a down payment.

Maybe you don’t have $2,000 burning a hole in your bank account, but perhaps you can afford to invest your lunch money. Brown-bag your lunch and sock away just $4 a day, 250 days a year. It’s not a lot, but if you’re in your early 20s, you’ve got the investor’s best ally on your side — time. If you invest $1,000 once a year in an investment that averages a 10% annual return — the average annual stock market return since 1926 — it’ll grow to more than $1 million after 46 years, which is right around the time you’ll be ready to retire.

Of course, as you get older and more financially stable, you should be able to put away more to invest. Upping the ante to just $166 a month — which is probably less than lunch money plus what you pay for cable TV — would put you at the million-dollar mark in just 39 years.

The power of compounding

The table below shows you how a single investment of $100 will grow at various rates of return. Five percent is about what you might get from a certificate of deposit (CD) or with a government bond over time, 10% is about the historical average stock market return, and 15% is what you might get if you decide to learn how to pick your own stocks and take advantage of some of our lessons in advanced investing techniques.
