자주 묻는 질문

What is a good credit utilization ratio?

Under 30% is the general guideline, but people with the highest credit scores keep utilization under 10%. The ideal sweet spot is 1% to 9%. Using 0% across all cards can sometimes score slightly lower than using a small amount.

Does credit utilization affect all three credit scores?

Yes. Utilization is calculated independently by each bureau based on the data they have. Since not all creditors report to all three bureaus, your utilization ratio may differ slightly across Equifax, Experian, and TransUnion.

How quickly does my score change when I lower utilization?

Utilization updates every billing cycle (roughly monthly). If you pay down your balance before the statement closing date, the lower utilization should be reflected on your credit report within one billing cycle. Score improvement can be almost immediate.

Should I pay my credit card before or after the statement date?

Pay most of the balance before the statement closing date so a low balance is reported. Then pay the remaining statement balance by the due date. This ensures low utilization is reported while still showing account activity.
