Why did my credit score drop after I paid off a personal loan?

What causes the drop: Your credit score reflects the live status of your credit accounts. An active installment loan contributes positively to credit mix (10% of FICO) and shows you are managing active debt obligations. When the account closes, that contribution stops. Average age of accounts can also decline if the paid-off loan was one of your older accounts.

Why it is not a problem: The positive payment history you built during repayment stays on your credit report for 10 years after the account closes. The score dip is a mechanical effect of account closure, not an indicator of creditworthiness decline. Future lenders reviewing your full history will still see years of on-time payments.

Why it usually reverses: Within 3-6 months of payoff, most borrowers see their score recover to pre-payoff levels or slightly higher. The improved DTI (lower monthly debt obligations) signals creditworthiness to scoring models even if it does not show directly in the FICO score.

If you need high credit score for near-term borrowing: If you are planning to apply for a mortgage or another major loan within 1-2 months, timing the payoff immediately before application can cost you a few points at the worst possible time. If the loan can wait 3-6 months after payoff for score recovery, this is preferable.

For someone with many open accounts: If you have 8-10 active credit accounts and pay one off, the mix impact is minimal. If the paid-off loan was your only installment account, the mix impact is larger. In that case, the dip may be 15-25 points rather than 5-10 points.
