Credit utilization is the relationship between a revolving balance and its available limit. Use the sliders to see the ratio and available room without entering personal information.
Divide the balance reported on revolving credit by the available credit limit. A lower ratio is often used as a helpful educational reference, but credit-scoring models vary and this tool cannot predict a score, a lender decision, or when an issuer will report.

How to read it
Start with the balance that may be reported
For a single card, divide the reported balance by the credit limit. For several cards, you can add the balances and limits for a combined illustration. Issuers and scoring models may treat timing and account details differently.
Check the statement or issuer information for the balance and limit.
Remember that utilization is only one part of a credit profile.
Do not close an account or change a payment plan based on this illustration alone.
Keep the context
A 30% reference is not a promise
Educational guidance often uses 30% as a reference point. It is not a guaranteed score threshold, and lowering a ratio does not guarantee approval or a particular outcome.
It is the balance reported on revolving credit divided by the available credit limit, expressed as a percentage. It is one factor in credit-scoring models, not a score prediction.
Is 30% a guaranteed credit-score rule?
No. Thirty percent is a common educational illustration, not a guaranteed threshold or universal scoring rule.
Does paying immediately change the reported ratio?
It can, depending on when the issuer reports and which balance is reported. Check the issuer’s information for timing.
