Debt consolidation consolidates multiple debts like credit cards and loans into a single loan with lower monthly payments. It can provide relief for those struggling with bills, but requires commitment to correct spending habits. A debt consolidation loan should be paid off quickly within 3-5 years to be cost effective, rather than extending the term for lower monthly costs but higher total interest. Online debt consolidation can make debt more manageable if used correctly as a foundation to improve financial planning, rather than just a temporary solution.
