Debt Consolidation vs Credit Scores: My Experience

Moving high credit card balances into a personal loan can trigger a FICO 8 jump of 40 to 90 points in about 90 days. The math is simple: you're shifting debt from "revolving utilization" (which is 30% of your score) to "installment debt," which doesn't hit your utilization ratio. If you're sitting at 60-90% utilization, this is a massive lever. If you're already under 30%, the impact is basically negligible.

I've been looking into the specific drivers behind this to optimize my own financial workflow, and it boils down to three things:

• Utilization Crash: This is the big one. If you have $8k in debt on a $10k limit, you're at 80%. A consolidation loan wipes that to 0% instantly.
• Credit Mix: FICO 8 gives 10% weight to your mix. Adding an installment loan when you only have cards usually adds a small bump (5-15 points).
• Payment Logistics: It's way easier to track one monthly payment than four different credit card dates. Since payment history is 35% of the score, reducing the "human error" risk of a missed payment is a huge win.

The actual impact depends entirely on where you start:

• Heavy users (75-95% utilization): Often see a gain of 60 to 110 points.
• Moderate users (35-60% utilization): Usually see 20 to 50 points.
• Light users (10-30% utilization): Maybe 5 to 15 points.
• Low balance users (<10%): Minimal to no change.

The trick to actually keeping those gains is leaving the paid-off cards open. Closing them kills your total available credit and spikes your utilization again the second you spend a dime. Just keep them at zero and don't apply for new credit while the reporting cycle resets.
