Does debt consolidation hurt your credit score?

Debt consolidation can cause a small, temporary dip in your credit score — mainly from the hard inquiry when you apply — but it often improves your score over time if you make on-time payments and lower your credit utilization.

The short-term dip: hard inquiry

When you apply for any new credit — including a consolidation loan — the lender runs a hard inquiry on your credit report. According to myFICO, a single hard inquiry typically lowers your FICO score by fewer than 5 points for most people, and the impact fades within 12 months. If you're rate-shopping multiple lenders, newer FICO models treat multiple inquiries for the same loan type within a 45-day window as a single inquiry.

Effects on credit utilization and credit mix

If you use a personal loan to pay off credit card balances, your revolving credit utilization ratio — which counts for about 30% of your FICO score — can drop significantly. Lower utilization generally lifts your score. Adding an installment loan also diversifies your credit mix (10% of your FICO score), which can be a modest positive if your file is heavy on revolving accounts. The CFPB notes that installment loans report monthly payment history, so consistent on-time payments build positive history over the loan term.

When consolidation can hurt your score long-term

Missing payments — payment history is 35% of your FICO score; a single late payment can drop your score significantly and stay on your report for up to 7 years.
Closing old credit card accounts — reducing your available credit limit raises your utilization ratio and shortens average account age, both of which can lower your score.
Continuing to run up balances after consolidating — eliminates the utilization benefit and leaves you deeper in debt.
Debt settlement (different from consolidation) — settling debts for less than owed is reported as a negative on your credit file and can significantly harm your score, per the CFPB.

Key takeaways

Applying for a consolidation loan triggers a hard inquiry — typically a drop of fewer than 5 points that fades within a year.
Paying off revolving balances lowers credit utilization, which can meaningfully improve your score in the near term.
The long-term outcome depends entirely on whether you make on-time payments and don't accumulate new balances.
Debt settlement is different from consolidation and carries far more severe credit damage — don't confuse the two.
