Enter the balances and limits shown on your credit reports to estimate your overall and per-card credit utilization. The calculator also shows how much the reported balance would need to fall to reach two illustrative ratios. It does not predict a credit score.

Use reported balances when you have them. Current app balances can differ from what a lender last sent to the bureaus.

How the calculator works
Overall utilization = total reported revolving balances ÷ total reported revolving limits × 100. For a single card with a $4,500 reported balance and a $10,000 limit, the ratio is 45%. If the reported balance falls to $3,000 with the same limit, the arithmetic ratio is 30%. The change will not appear in a score based on the older report data.
With more than one card, add the balances first and add the limits separately. Do not average the cards’ percentages. A card with a $900 balance on a $1,000 limit and another with a $100 balance on a $9,000 limit have a combined $1,000 balance on $10,000 of limits, or 10% overall. The first card still has 90% individual utilization, and some FICO scoring models consider individual revolving accounts as well as the overall ratio.
What the 30% and 10% examples mean
These are planning examples, not score cutoffs. The Consumer Financial Protection Bureau notes that some experts advise no more than 30% of total credit limits while others suggest less than 10%. There is no universal promise that reaching either figure will raise your score by a particular number of points. Paying a statement in full by its due date is different from paying early to change the balance an issuer may report; you do not need to carry interest-bearing debt to build a credit history.
Check these details before you act
- Reported balance: Your live card balance may not match the latest balance on a credit report. Check the report’s update date and your issuer’s statement cycle.
- Credit limit: A limit decrease can raise the ratio even without new purchases.
- Card type: This tool models credit cards with a stated revolving limit. Other accounts, closed cards with balances, or unusual credit lines may be handled differently by a scoring model.
- Payments: The payment estimate assumes no new charges, fees, interest, or limit changes before the next reported balance. It is arithmetic, not a payment recommendation.
- Other score factors: Payment history, negative accounts, account age, and the scoring model also matter. The calculator cannot forecast approval, rates, or score changes.
