Where to put $5,000 now

This is the best move, and yes, you've heard this all before, but it's still true.

As a way to build money for retirement, nothing comes close to a 401(k). Saving by payroll deduction is painless and ensures that you make regular contributions.

You get a tax break on what you put in, and the money grows tax-free until you withdraw it when you reach retirement.

Best of all, your employer probably matches your contributions, typically 50 cents on the dollar (on up to 6 percent of your salary) - for an immediate 50 percent return on investment.

$7,500 in a 401(k) today equals $34,957 in 20 years (assuming an 8 percent annual return).
