Understanding Credit Utilization: How It Affects Your Credit Score

Updated Aug 1, 2025

Your credit utilization ratio—the portion of your available credit that you’re actually using—is one of the most influential factors in calculating your credit score. It typically accounts for about 30% of your FICO or VantageScore and can significantly impact your eligibility for loans, cards, and better interest rates.

How Credit Utilization Is Calculated

To calculate your utilization ratio:

  • Add up all your credit card balances (or other revolving credit balances).
  • Add up all your credit limits across those accounts.
  • Divide your total balance by your total credit limit.
  • Multiply by 100 to express it as a percentage.

For example, if you owe $3,000 across all cards and your combined limits equal $15,000, your utilization ratio is 20% ($3,000 ÷ $15,000).

Why It Matters in Your Credit Score

Credit scoring models like FICO factor utilization as the second-largest component after payment history. A lower ratio indicates better credit management and lower risk—leading to higher scores.

Studies show that consumers with excellent credit often maintain around 5% utilization, while even utilization below 30% is often considered healthy.

What Is a Good Credit Utilization Ratio?

General guidelines are:

  • Excellent: under 10%
  • Very good: 10%–30%
  • Fair or risky: above 30%

Keeping balances low and paying before your statement closing date can ensure lenders see your utilization in a positive light.

Strategies to Lower Your Credit Utilization

  • Pay down your balances early and often: making payments before the statement closes can reduce what gets reported.
  • Increase your credit limit: higher limits (without increasing spending) lower your ratio.
  • Avoid closing unused cards: closing an account reduces your available credit and may raise utilization.
  • Use business credit cards that don’t report to consumer bureaus: they can help preserve your personal utilization.

Common Pitfalls to Avoid

  • Loading up low-limit cards can spike utilization quickly—even if balances are modest.
  • Opening many new cards at once can hurt your score temporarily and increase utilization risk if balances remain high.
  • Canceling cards immediately after opening them (especially older ones) can reduce history and available credit.

Why 0% Utilization Isn’t Ideal

Altogether, avoiding credit use may seem safe, but lenders prefer to see responsible usage. A low utilization (e.g., 1%–5%) shows you can borrow and repay rather than leaving accounts dormant.
