This year's tax-filing deadline has, thankfully, come and gone, but it's always a fine time to begin (or continue) fully funding a Roth for the 2007 tax year -- and beyond. Plain and simple, if you want to accelerate your road trip to financial freedom, you owe it to yourself to kick in as close to the maximum as you possibly can (assuming you are eligible) -- $5,000 if you were 50 or older last year and $4,000 for the "youngsters." Tax-free growth, after all, doesn't grow on trees.
Do the math
To get a clear sense of how much maxing out a Roth can matter, consider an investment of $4,000 plunked down on Vanguard 500 Index
Since its inception back in the bicentennial year of 1976 through the end of this past March, Vanguard 500 delivered an annualized return of roughly 12.2%. There's no guarantee that the fund will continue delivering at that pace, of course, so for the sake of our example, we'll assume 10.5%, the market's historical rate of return.
Crunching the numbers, we find that a 30-year-old investor who begins making an annual Roth contribution of $4,000 this year will wind up more than $700,000 in her account when she hits 60. Our savvy investor won't have paid any taxes on the fund's distributions along the way, and when she begins drawing down the account after age 59 1/2, she won't owe Uncle Sam a dime either.
Got your attention?
Sweet as the Roth deal is, there is some fine print you'll need to tend to. For starters, not everyone will qualify for a Roth, and those who do may face reduced contribution limits based on how much they earn. What's more, as I point out here, index funds aren't the best way to take advantage of a Roth's tax-fighting superpowers.
Among other things, you might want to consider reserving a Roth account for investments that generate income that would be taxable in a plain-vanilla account. On that front, Washington Mutual
