If your credit card balances are rising, the most useful score-related step is to understand how those balances compare with your available credit. That ratio—called credit utilization—can affect a FICO Score, but there is no single percentage that guarantees a particular result. Keep payments on time, reduce debt when your budget allows, and do not carry a balance or pay interest just to build credit.
What credit utilization measures
Credit utilization is the portion of your available revolving credit that is in use. FICO identifies it as an important factor within the “amounts owed” category of a FICO Score. Higher utilization can weigh negatively, though its effect depends on the scoring model and the rest of your credit file.
Calculate utilization for one card
Divide the card’s balance by its credit limit, then multiply by 100. For example, a $2,000 balance on a $5,000 limit is 40% utilization for that card.
Calculate overall utilization
Add the balances on revolving accounts and divide by the sum of their applicable credit limits. FICO gives the example of a $10,000 balance on a $20,000 limit: that is 50% utilization. Your own calculation from current account figures is an estimate; the credit report used by a score may show different balances.

Is 30% a credit-score cutoff?
No. The Consumer Financial Protection Bureau says experts advise using no more than 30% of total credit limits. Treat that as a general guideline, not a cliff where every score suddenly drops or recovers. FICO says lower utilization is generally better, but the effect varies with the rest of the report.
There are two different “30%” figures worth keeping separate: the CFPB’s 30% utilization guideline and FICO’s statement that the amounts-owed category accounts for about 30% of a typical FICO Score. The latter is a category weighting, not a recommended balance-to-limit ratio.

Why your reported balance may differ from your current balance
The balance in your card issuer’s app can change before the balance on your credit report does. FICO says the latest statement balance is generally what appears on a credit report, although issuer reporting schedules may vary. As a result, paying your statement in full by its due date may still leave a balance reported for that period.
You can ask your issuer when it typically reports account information. Paying earlier may affect the balance that gets reported, but timing is not a substitute for paying on time or reducing debt, and no payment timing guarantees a particular score change.

Protect your payment history first
Pay every bill on time, and get current as soon as possible if you have missed a payment. The CFPB identifies on-time payments as the leading score-building behavior. A utilization adjustment should not take priority over avoiding late payments.
Reduce balances as your budget allows
Lower balances relative to available limits can help utilization, while paying down principal also addresses the debt itself. Choose a repayment pace you can sustain alongside essential expenses and minimum payments. Do not take on costly new borrowing solely to try to improve a score; compare any repayment option by its interest and fees, effect on principal, payment reliability, and impact on available credit.
Rank #4
Do not carry a balance to build credit
The CFPB says, “You don’t need to carry a balance on credit cards to get a good score.” You can use a card and pay its statement balance in full without paying interest just to create utilization. Debt and utilization are related, but they are not the same thing.
How closing a card or losing a limit can change the ratio
If you close a card or an issuer lowers its limit while you still owe money elsewhere, your total available credit may shrink. The same balances divided by a smaller total limit produce higher overall utilization. FICO notes that closures and limit decreases can have different score outcomes depending on the credit report and what happens afterward; neither action guarantees a specific change.

Before closing an account, consider why you want to close it and whether the remaining limits would leave your balances at a much higher share of available credit. Do not keep a card or accept a limit increase solely for a score calculation if doing so would create costs or encourage more spending.

If you are struggling to make payments, a reputable nonprofit credit counselor may be a useful place to seek help. Verify a provider’s fees, services, eligibility requirements, and program status before enrolling; counseling does not guarantee a particular outcome. The CFPB’s guidance on credit and debt can help you understand the issues to discuss.
