Frequently Asked Questions

What is a credit utilization ratio?

Your credit utilization ratio is the percentage of your available revolving credit that you're currently using. It's calculated by dividing your total credit card balances by your total credit limits. For example, if you owe $5,000 across cards with a combined limit of $15,000, your utilization rate is 33.33%.

Why does my credit utilization ratio matter?

Credit utilization accounts for roughly 30% of your FICO credit score, making it the second most important factor after payment history. High utilization signals to lenders that you may be over-reliant on credit, which can lower your score and make it harder to qualify for new credit or favorable interest rates.

What is a good credit utilization ratio?

Most credit experts recommend keeping your utilization below 30%, but the best scores typically belong to people who stay under 10%. A ratio of 0% (carrying no balance) is technically possible and not harmful, though having some small activity can be beneficial for demonstrating responsible credit use.

Is my total utilization ratio or per-card ratio more important?

Both matter to your credit score. FICO and VantageScore consider utilization on each individual card as well as your overall ratio. Even if your total utilization is low, maxing out a single card can hurt your score. It's best to keep both your overall and per-card rates well below 30%.

How do I calculate my credit utilization ratio across all cards?

Add up all your current card balances, then add up all your credit limits. Divide total balances by total limits and multiply by 100 to get your percentage. For example: ($1,400 + $1,100 + $2,500) ÷ ($4,000 + $4,000 + $7,000) = $5,000 ÷ $15,000 = 33.33%.

How can I lower my credit utilization ratio?

The most direct way is to pay down your existing balances. You can also request a credit limit increase on your current cards, open a new credit card (which increases total available credit), or spread purchases across multiple cards to avoid maxing any single one. Avoid closing old cards, as this reduces your total available credit.

Should I open a new credit card to improve my credit utilization?

Opening a new card increases your total available credit, which can lower your overall utilization ratio. However, each new application triggers a hard inquiry that can temporarily dip your score by a few points. If your utilization is causing significant score damage, the long-term benefit may outweigh the short-term inquiry impact.

Is a 0% credit utilization ratio good or bad?

A 0% utilization — meaning you carry no balance at all — is generally not harmful and won't tank your score. However, some scoring models may view having no activity as slightly less favorable than a very low (1–9%) utilization. Paying your balance in full each month before the statement closes is the best strategy.
