3 Money Rules That Can Help You Retire a Millionaire

When you think about retiring a millionaire, it may sound like you could live like the rich and famous -- spending your retirement on a yacht, sipping champagne from gold-plated glasses.

But in reality, $1 million may or may not be enough to last through retirement, even if you live a modest lifestyle. Consider the 4% rule, which states that you can withdraw 4% of your savings during the first year of retirement, then adjust your withdrawals each year afterward for inflation. If you have $1 million saved by retirement age, the 4% rule suggests you can withdraw $40,000 your first year. That's not exactly the life of luxury that comes to mind when you picture becoming a millionaire.

In other words, $1 million isn't necessarily a far-fetched retirement goal -- so it's a good idea to save more than you think you need to. Retiring a millionaire may not be easy, but it's absolutely doable if you follow a few simple money rules.

1. Don't be too conservative with your investments

Playing it safe with your money may sound like the most practical thing you can do to establish a solid retirement fund. However, play it too conservatively and you may end up doing more harm than good.

For anyone who's not already a member of the super-wealthy club, one of the best ways to accumulate enough savings to reach millionaire status is to invest in the stock market. Now, that's not to say you should invest your life savings in that hot new tech start-up; instead, put your money in low-cost index funds and mutual funds. Although the stock market will always experience ups and downs, these types of investments are a relatively safe bet over the long term. Over the course of several decades, you'll typically see average annual returns of around 6% to 10% with these investments.

Compare those returns, then, to the returns you'd see with a savings account or lower-risk investments like CDs and money market accounts. Even the best savings accounts have interest rates of around 2%, and the annual returns for CDs and money market accounts typically hover around 2% to 3%. At that rate, your savings may not even outgrow inflation -- meaning your money could actually lose value the longer you keep it in these types of accounts.

The difference is eye-popping when you look at the big picture, too. Say you're 30 years old with nothing saved for retirement, and you're saving $500 per month. If you're earning an 8% annual return on your investments, you'd have just over $1 million saved by age 65. A 2% annual return, however, will result in total savings of just $300,000, all other factors remaining the same.
