A friend of mine works for a debt consolidation firm whose internal statistics estimate that 78% of the time, after someone consolidates his credit card debt, the debt grows back. Why? He still doesn't have a game plan to either pay cash or not buy at all. He also hasn't saved for "unexpected events" which will also become debt.
Debt consolidation seems appealing because there is a lower interest rate on some of the debt and a lower payment. However, in almost every case we review, we find that the lower payment exists not because the rate is actually lower but because the term is extended. If you stay in debt longer, you get a lower payment, but if you stay in debt longer, you pay the lender more, which is why they are in the debt consolidation business.
