NEW YORK (TheStreet) -- The roof starts to leak, a child needs braces, a spouse loses a job ... At one time or another, nearly everyone has a sudden, unexpected need for cash. And the 401(k) may look like a lifesaver.
Though experts typically caution against taking loans from the 401(k), the strategy has its good points. For one thing, the interest rate is relatively low, often the prime rate (currently 3.25%) plus 1%, and you pay the interest back into the account, not to an outside lender such as a credit card company. So you're really paying yourself.
You won't have to jump through approval hoops such as a credit or income check, and there are no tax consequences or penalties if the loan is paid back according to the rules. Loans are typically limited to half of the account or $50,000, whichever is less, and the repayment period is no longer than five years.
But on the down side, the loan, until it is repaid, reduces the size of your 401(k) account, cutting your investment returns. That undermines the account's primary goal of investing for retirement.
So when does a 401(k) loan make sense, and when does it not?
"On the scale of most to least attractive sources of emergency cash -- with the most attractive being an emergency fund and least attractive a payday loan -- 401(k) loans rank somewhere in the middle," says Christine Benz, director of personal finance at Morningstar, the market-data firm.
