About Credit Utilization

Credit utilization is one of the most important factors in your credit score calculation, typically accounting for about 30% of your score. It represents the percentage of your available credit that you're currently using.

Impact on Credit Score
  • Excellent (1-9%): Optimal for your credit score
  • Good (10-29%): Still positive for your score
  • Fair (30-49%): May start to negatively impact your score
  • Poor (50-74%): Likely decreasing your credit score
  • Very Poor (75%+): Significantly hurting your credit score
Tips to Improve Your Credit Utilization
  • Pay down your credit card balances
  • Request credit limit increases
  • Keep older credit cards open, even if unused
  • Consider making multiple payments during the billing cycle
  • Apply for a new credit card (though this may temporarily decrease your score)
Individual vs. Overall Utilization

Both your individual card utilization and your overall utilization across all cards affect your credit score. Having even one maxed-out card can negatively impact your score, even if your overall utilization is low. Aim to keep balances low across all your cards.

What Is the Credit Utilization Calculator?

The Credit Utilization Calculator helps you understand how much of your available credit you're currently using. This is known as your credit utilization ratio—a key factor that affects your credit score. A lower ratio typically means better credit health.

Think of this tool as your credit awareness assistant. Whether you're monitoring spending or planning to apply for a loan or credit increase, knowing your credit utilization can help you make more informed decisions.

Credit Utilization Ratio Formula:
Credit Utilization Ratio = (Total Balance ÷ Total Credit Limit) × 100%

How to Use the Calculator

  • Enter each credit card's name, current balance, and credit limit.
  • Click "Add Card" to include more cards, or remove any with the × button.
  • Select your preferred decimal precision (e.g., 1 or 2 decimal places).
  • Choose whether to display details for each card and an explanation of the results.
  • Click "Calculate" to see your overall and individual utilization rates.
  • Click "Reset" to clear the inputs and start over.

Why Credit Utilization Matters

Credit utilization is one of the most influential parts of your credit score, making up around 30% of your total score. It shows how responsibly you manage borrowed credit. Even if you're never late with payments, a high utilization rate can negatively impact your score.

  • Excellent (1-9%) – Ideal range for strong credit scores
  • Good (10-29%) – Generally positive
  • Fair (30-49%) – May start affecting your score
  • Poor (50-74%) – Likely causing credit score declines
  • Very Poor (75%+) – Significantly damaging to your score

Frequently Asked Questions (FAQ)

What is a good credit utilization rate?

A good rule of thumb is to keep your utilization under 30%. For maximum credit score benefits, aim for under 10%.

Does 0% utilization hurt my credit?

No, it doesn’t hurt your credit, but some scoring models prefer to see small usage (e.g., 1-9%) to show active use of credit.

Do individual card utilizations matter?

Yes. Even if your overall utilization is low, one maxed-out card can negatively impact your score. The calculator shows each card’s utilization for this reason.
