Will my credit score drop if I max out my credit card, then pay it off with a personal loan?

The timing issue: Credit scores are calculated at a moment in time using the balances reported on your statement closing date. If your card shows a $9,800 balance on a $10,000 limit on the closing date, utilization is 98% - a severe hit to your score. This can show up in your score even if you pay in full each cycle, because the closing balance (not the payment) is what gets reported.

The rapid recovery: Once the personal loan pays off the credit card and the card reports a near-zero balance, your utilization drops dramatically. Utilization (30% of FICO) recovers quickly because it is not time-weighted - one low-utilization reporting period completely resets the factor. Most borrowers see a 20-60 point improvement in the first billing cycle after paying off high-balance cards.

Net effect of the debt consolidation strategy: Month 0 (cards maxed): Score at recent low due to high utilization. Month 1 (personal loan opens, cards paid): Hard inquiry and new account cost 10-15 points; utilization improvement adds 20-60 points. Net: typically positive. Month 3-12: Personal loan on-time payments continue building history. Score typically surpasses pre-consolidation levels.

Most common mistake: Not keeping the paid-off credit cards at zero or low balance after payoff. If you accumulate new card balances after consolidation, you end up with both the personal loan payment and card debt - the financial situation worsens rather than improves.

For mortgage applicants: If you are applying for a mortgage, lenders review the last 2-3 months of statements. A spike followed by a payoff looks better than a sustained high balance. However, opening a new personal loan (especially within 90 days of mortgage application) can complicate underwriting. Consult a mortgage broker before opening a personal loan if a home purchase is imminent.
