I have good credit, would you co-sign a car loan for me for free? No? How much would I have to pay you to make it worth co-signing? That's the value of the loan guarantee to you. The value to me is how much I save on interest due to your guarantee. Or, if I can't buy a car without your signature, the value to me is the difference between the value of owning a car vs. not owning one.
