text:  Dollar Loan Center's interest charges are so straightforward. Could you break that down for me? Well, first of all, you only pay the interest for the time you have the loan out. Other lenders charge upfront fees or even hold your car title or a check. Okay, I'm with you so far, but how much exactly? Well, let's use a $500 loan as an example. That interest is $2.75 a day. If you need a loan for 10 days, the interest is $27.50. That's it. Real easy math. You can pay it off in a couple days or take up to a year if you need. Your choice.
