I'm retired and 66 years old, working part time on as-needed basis. I need to replace my car and plan to buy to buy a used one. Is buying it with a loan against my 401(k), a good idea? — Robert Gill

Paul Solman:

Depends on your alternatives, Robert. If the only other way to buy the car is a standard car loan, then yes, I'd borrow from my 401(k), because I'd undoubtedly be paying it back at a lower — perhaps much lower — interest rate.

But if I had enough money sitting in a bank, I'd be inclined to spend that before borrowing, as I'd be getting no return at all on the bank account, while I would be getting a return on the money in the 401(k).


Admittedly, there can be a practical problem in draining a bank account: I might not have enough cash easily accessible to cover an unexpected expense. Yes, I could always borrow from the 401(k), meaning that it can be used as a rainy day fund. But it can take time to get the money, and if I were to need it right away...

That, at any rate, is how I have thought about the problem when faced with it years ago (though not involving a car purchase).

As with all economic decisions in life — as with all decisions, period — it's a matter of weighing the costs against the benefits. Hard to calculate what the benefit of a cash cushion in the bank represents for you, but since it hinges on peace of mind, you'd know better than I.
