Credit Utilization Ratio Guide

Credit utilization is one of the most powerful and controllable factors in your credit score. At 30% of your FICO score, it's second only to payment history — and unlike a late payment, it can be fixed in a single billing cycle.

The Basic Calculation

Utilization is calculated two ways — and FICO looks at both:

• Per-card utilization: Individual card balance ÷ individual card limit
• Overall utilization: Total balances on all cards ÷ total limits on all cards

A single maxed-out card drags your score even if your overall rate is low. The calculations are separate and independent.

When Utilization Is Measured

This is the piece most people get wrong: your utilization is measured when your card issuer reports to the bureaus — which happens at your statement closing date, not your payment due date. If you pay in full every month but your statement closes with a $1,500 balance on a $2,000 limit card, your bureau reports 75% utilization — even though you've never paid a cent in interest.

The fix: pay your balance down before your statement closing date, not before the due date. Use our Statement Closing Planner to track this.

Target Utilization by Score Goal

• Under 5%: Optimal for 800+ scores — but report at least $1, not $0
• Under 10%: Strong; target for mortgage applications
• Under 20%: Good for most lending purposes
• Under 30%: "The rule" — but actually just the ceiling of acceptable
• 30–50%: Noticeable score impact; worth addressing
• Over 50%: Significant negative impact

Fastest Ways to Lower Utilization

1. Pay balances before the statement closing date (not just the due date)
2. Request a credit limit increase on existing cards — instantly lowers your ratio without any payment
3. Open a new card — adds available credit (but requires a hard inquiry)
4. Pay the highest-utilization card first — per-card utilization matters, not just aggregate

The $0 Balance Myth

Reporting $0 on all your cards is not optimal. FICO's scoring algorithm responds slightly better to seeing a small, managed balance — even just 1–3% of the limit. Keep one card reporting a small balance while keeping the others at $0.

Utilization Resets Monthly

Unlike late payments that stay for 7 years, utilization is recalculated every month with fresh data. Pay down a maxed-out card this cycle and your score improves within 30–45 days of the next statement close.
