Frequently Asked Questions
How much does credit utilization affect my score? ▾
Credit utilization makes up approximately 30% of your FICO score — the second most important factor after payment history. At under 10% utilization, you'll see the highest scores. Above 30%, scores start to drop meaningfully. Above 50%, the impact is significant. Above 90% (maxed out cards), the damage is severe. The good news: utilization changes are reflected immediately in your score — paying down debt can improve your score within one billing cycle.
Is it better to have zero balance or a small balance? ▾
Contrary to popular myth, you don't need to carry a balance to build credit. The optimal strategy is to use your cards regularly (which keeps them active and shows payment history) but pay the full balance before the statement closes — giving you 0% utilization on that card. If you want to show utilization activity, let a small amount (1-5%) report to the bureaus by not paying until after the statement closes, then pay in full by the due date.
Does utilization affect all cards or just overall? ▾
Both matter. FICO looks at individual card utilization (each card) AND overall utilization (all cards combined). Having one card at 80% can hurt your score even if your overall utilization is 25%. Try to keep each individual card below 30%, not just the aggregate. This is why having one card with a high balance is worse than spreading the same balance across multiple cards.
