For example, let's say you have $30,000 in unsecured debt, including a two-year loan for $10,000 at 12%, and a four-year loan for $20,000 at 10%. Your monthly payment on the $10,000 loan is $517 and $583 on the $20,000 loan, for a total payment of $1,100 per month. The debt consolidation company tells you they have been able to lower your payment to $640 per month and your interest rate to 9% by negotiating with your creditors and rolling the loans together into one. Sounds great, doesn't it? Who wouldn't want to pay $460 less per month in payments?
But they don't tell you that it will now take you six years to pay off the loan. This may not sound that bad to you at first unless you realize how much more you will actually pay in additional payments. You will now pay $46,080 to pay off the new loan vs. $40,392 for the original loans, even with the lower interest rate of 9%. This means you paid $5,688 more for the "lower payment." Not such a good deal after all. This example shows you why they are in the business – because they make money off of you.
