What is a debt consolidation loan?

A debt consolidation loan is a new loan you take out to pay off multiple existing debts — credit cards, medical bills, personal loans — so you have one monthly payment, ideally at a lower interest rate than the debts you're replacing.

A debt consolidation loan is a personal installment loan used specifically to pay off several existing debts at once. Instead of tracking multiple due dates and interest rates, you make one fixed monthly payment to a single lender. The math only works in your favor if the new loan's annual percentage rate (APR) is lower than the weighted average APR of the debts you're consolidating — so comparing offers carefully before signing is essential.

How debt consolidation loans work

You apply for a personal loan equal to (or slightly above) your total outstanding balances. If approved, the lender either pays your creditors directly or deposits the funds so you can pay them off. You then repay the new loan in fixed monthly installments over a set term — commonly 24 to 84 months. Because personal loan rates are often lower than credit card rates, the same monthly payment can retire the debt faster. The CFPB's guide to debt consolidation explains the tradeoffs in plain language.

Secured vs. unsecured consolidation loans

Unsecured personal loans require no collateral. Approval and rate depend heavily on your credit score and debt-to-income ratio.
Secured consolidation loans (home equity loans, HELOCs) may offer lower rates but put your home at risk if you default.
Balance-transfer credit cards with a 0% intro APR are a consolidation alternative for smaller balances — but the promotional rate expires.
Debt management plans (DMPs) through nonprofit credit counseling are another route that doesn't require a new loan.

When consolidation makes sense — and when it doesn't

Consolidation is most effective when you qualify for a meaningfully lower APR, you have a stable income to meet the new fixed payment, and you address the spending habits that created the original debt. It does not erase what you owe — it restructures it. If you consolidate credit card debt and then run the cards back up, you can end up deeper in debt than before. The FTC's guidance on credit counseling and debt relief covers how to evaluate consolidation against other approaches.

Key facts

Debt consolidation combines multiple debts into a single payment, ideally at a lower interest rate, but does not reduce the principal you owe. — CFPB
A balance-transfer card or home equity loan can also be used to consolidate debt, each with different risk profiles and qualification requirements. — CFPB
The FTC advises consumers to compare debt consolidation against nonprofit credit counseling and to watch for upfront fees from for-profit debt-relief firms. — FTC

Key takeaways

A debt consolidation loan pays off multiple existing debts and replaces them with one monthly payment.
The math only works in your favor if the new APR is lower than your current weighted-average APR.
Unsecured personal loans are most common; secured options (home equity) carry lower rates but higher risk.
Consolidation restructures debt — it does not eliminate it. Changing spending behavior is equally important.
Compare at least three lender offers and check for origination fees, which can erode the interest-rate savings.
