Reported balance versus current balance
Credit scoring generally uses account information reported to a credit bureau. That balance is often from the latest statement and can differ from the live balance in an issuer’s app.
Credit Utilization Calculator
Add each credit card or other revolving account you want to include. The calculator totals the balances and limits, identifies the highest individual ratio, and estimates how much the combined balance would need to fall to reach your chosen planning target.
Accounts and target
A planning target only; 30% is not a scoring guarantee or hard cutoff.
Enter at least one reported balance and credit limit, then calculate.

“To target” applies the selected target to each account separately. Paying that total is a stricter card-by-card scenario than only reaching the target overall.
Credit Utilization Formula
Overall utilization = (total reported revolving balances ÷ total revolving credit limits) × 100For one account, use that account’s reported balance and limit. For an overall ratio, sum balances first and sum the corresponding limits first; do not average the individual percentages.
Worked example
Suppose Card A reports a $1,200 balance on a $5,000 limit and Card B reports $300 on a $3,000 limit. The overall ratio is ($1,200 + $300) ÷ ($5,000 + $3,000) × 100 = 18.75%. Card A is at 24%, while Card B is at 10%.
At a 10% overall target, the combined target balance is $800, so the estimated balance reduction is $1,500 − $800 = $700. Interest or new purchases are not part of this simple snapshot.
How to Read Your Credit Usage Ratio
Overall and individual ratios both matter
A low combined ratio does not hide a nearly maxed-out card. Review the highest individual ratio as well as the overall percentage.
Thirty percent is a benchmark, not a cliff
Consumer guidance often mentions staying below 30%, but FICO says there is no single optimal threshold. Generally, lower reported utilization is associated with less risk.
Utilization can exceed 100%
A balance can exceed its stated limit because of interest, fees, a reduced limit, or over-limit activity. The calculator displays ratios above 100% instead of capping them.
Paying in full and reporting timing
Paying a statement in full avoids carrying that statement balance forward, but an issuer may have already reported a balance before the due date.
Closing a card can change the denominator
If an unused card’s limit stops counting while other balances remain, the total limit falls and utilization can rise. Account age, fees, security, and spending control may also matter.
Credit Utilization FAQ
How do I calculate credit utilization?
Divide a reported revolving balance by its credit limit and multiply by 100. For an overall ratio, divide total included balances by total included limits.
Is utilization calculated per card or overall?
Both can matter. This tool shows the combined ratio and every account’s individual ratio.
Is 30% a hard cutoff?
No. It is a common planning benchmark, not a guaranteed score boundary. The impact depends on the scoring model and the rest of the credit file.
Which balance should I enter?
Use the balance shown on a credit report when estimating what a scoring model may see. Use a current balance only for a live personal planning snapshot.
Does paying in full mean 0% utilization?
Not always. An issuer may report a statement balance before the payment due date, even when the statement is later paid in full.
Do installment loans count?
Not in this revolving-utilization calculator. Mortgages, auto loans, and other installment debt use different balance-to-loan calculations.
What if an account has no preset limit?
Do not invent a limit. Credit-report and scoring treatment can vary, so omit the account here or use the limit value actually shown on the report.
Can this predict my credit score?
No. It calculates ratios only. It cannot reproduce a proprietary scoring model or predict a lender’s decision.
Method, Privacy, and Sources
Method
Balances and limits are added with full precision. Ratios are calculated before display rounding. Paydown estimates exclude interest, fees, pending purchases, refunds, and reporting delays.
Privacy
The calculator runs entirely in your browser. It does not request names, account numbers, logins, or other identifiers, and entered values are not stored by this page.
Limits
This educational result is not financial, legal, lending, or credit-repair advice. It does not estimate a credit score or guarantee a score change, approval, rate, or reporting date.
