Key takeaways

  • A consolidation loan is a personal loan used to pay off several debts, leaving you with one fixed monthly payment.
  • It saves money only if the new APR (including fees) is lower than what you're paying now.
  • Checking your rate with a soft credit pull doesn't affect your credit score.

A debt consolidation loan is a type of unsecured personal loan. You borrow a lump sum, use it to pay off existing debts — usually credit cards — and then repay the new loan in fixed monthly installments over a set term, often two to seven years.

How it works, step by step

  1. Add up the balances and APRs of the debts you want to consolidate.
  2. Prequalify with one or more lenders to see estimated rates (usually a soft credit check).
  3. Compare the APR, origination fee, term length, and monthly payment.
  4. If approved, the lender either pays your creditors directly or deposits funds for you to do it.
  5. Make one fixed payment each month until the loan is paid off.

The potential benefits

  • A lower interest rate than many credit cards, depending on your credit profile.
  • A fixed payoff date, rather than revolving debt with no end in sight.
  • One payment to track instead of several due dates.
  • Possible credit score improvement over time as card utilization drops.

The trade-offs

  • Origination fees (often 1%–10%) can reduce the savings.
  • Longer terms mean lower payments but potentially more total interest.
  • If you keep using the paid-off cards, you can end up with more debt than before.
  • Borrowers with lower credit scores may not get a rate that beats their current cards.

Is it right for you?

Consolidation tends to make the most sense for people with steady income, fair-to-good credit, and a balance they can realistically pay off within the loan term. If you're struggling to make minimum payments at all, a nonprofit credit counselor may be a better first call.

Quick test

Compare total cost, not just the monthly payment. Multiply the new payment by the number of months and add any fees — then compare to what you'd pay staying the course.
