Credit utilisation is one of the biggest factors in your credit score. Learn what it is, how it's calculated, and why keeping it low matters.

Key Takeaways

  • Credit utilisation is the share of your revolving credit limit that you are currently using, expressed as a percentage.
  • It typically accounts for roughly 30% of a FICO score, making it one of the most influential scoring factors.
  • Most credit experts suggest keeping utilisation below 30%, though lower is generally better.
  • Both your total utilisation across all cards and each individual card's utilisation can affect your score.
  • Paying down balances and requesting a credit limit increase are two straightforward ways to lower utilisation.
  • This article provides general financial education and is not personalised financial advice.

How Credit Utilisation Is Calculated

The formula itself is straightforward: divide your current revolving balance by your total revolving credit limit, then multiply by 100 to get a percentage.

Example: Two credit cards — one with a $5,000 limit carrying a $1,500 balance, and another with a $3,000 limit carrying a $600 balance. Your total balance is $2,100, your total limit is $8,000, and your overall utilisation is roughly 26%.

Scoring models also evaluate each card individually. A single maxed-out card can drag down your score even if your overall utilisation looks fine, so it is worth monitoring each account separately. For a broader look at how this fits into the full scoring picture, see how credit scores are calculated.

~30%

Share of FICO score tied to credit utilisation

According to FICO, amounts owed — which includes utilisation — represents approximately 30% of a standard FICO score calculation.

<10%

Utilisation typical of highest-scoring consumers

Data from FICO indicates that consumers with scores above 800 tend to use well under 10% of their available revolving credit on average.

30%

Commonly cited utilisation guideline

Many consumer finance educators and credit counselors recommend keeping utilisation below 30% as a practical rule of thumb for maintaining a healthy score.

Why It Carries So Much Weight

Among the factors that determine a FICO score, payment history is the largest single component, but credit utilisation follows closely behind. High utilisation signals to lenders that a borrower may be stretched financially — relying heavily on credit to cover everyday expenses or carrying balances that could become difficult to manage.

Importantly, utilisation is a snapshot, not a long-term record. Unlike missed payments, which remain on your credit report for seven years, utilisation resets each time your lenders report new balances. This means it is one of the more responsive levers available for improving a score in a relatively short timeframe.

“Amounts owed is about more than the raw dollar figure. It reflects the proportion of available credit being used, and high proportions can indicate greater credit risk even when payments are made on time.”

Be aware of a common misconception: carrying a small balance month to month does not help your score. It only adds interest charges. Paying in full is both financially and credit-score-wise the stronger habit. Explore more of these widely believed credit score myths to separate fact from fiction.

Practical Ways to Lower Your Utilisation

Reducing your utilisation ratio comes down to two variables: lower your balances, raise your available credit, or do both.

  • Pay down existing balances: Even a partial paydown before your statement closing date can reduce the balance your issuer reports to the bureaus.
  • Make mid-cycle payments: You are not limited to one payment per month. A payment made before the statement closes can reduce your reported balance.
  • Request a credit limit increase: If your account is in good standing, many issuers will approve a higher limit. A higher limit with the same balance lowers your ratio automatically.
  • Avoid closing old accounts: Closing a card removes its limit from your total available credit, which can push utilisation upward. Learn more about habits that gradually erode a healthy credit profile.

Time Your Payments Strategically

Check your credit card statement's closing date — this is usually when your issuer reports your balance to the credit bureaus. Making an extra payment a few days before that date can lower the balance that gets reported, potentially reducing your utilisation ratio for that billing cycle.

Frequently Asked Questions

Most credit guidance recommends staying below 30%, but consumers with the highest credit scores often maintain utilisation below 10%. There is no single magic number, but lower is consistently better from a scoring perspective.
Not necessarily. Card issuers typically report your balance to the credit bureaus on your statement closing date, which may be before your payment is due. Even if you pay in full each month, a high balance at the reporting date can still show elevated utilisation.
Opening a new card increases your total available credit, which can lower your overall utilisation ratio if your balances stay the same. However, a new account also generates a hard inquiry and reduces your average account age, so the net effect on your score depends on your full credit profile.
Utilisation is recalculated each scoring cycle based on the balances reported by your lenders. Because it is not a cumulative or historical factor, paying down a balance can improve your score relatively quickly — often within one to two billing cycles after the lower balance is reported.
Some research suggests that having at least a small amount of utilisation — rather than zero — may be marginally better than showing no activity at all. However, this effect is minor, and consistently low utilisation is far more important than worrying about hitting an exact target.
