Credit utilization is the amount of revolving credit being used divided by the total revolving credit available.
supported · checked Sep 21, 2026Closing a credit-card account can increase utilization by reducing total available credit while balances remain unchanged, which can lower a score.
supported · checked Sep 21, 2026Credit scoring models consider how close revolving balances are to available credit limits, and high utilization can negatively affect scores.
supported · checked Sep 21, 2026A credit score can be calculated while a high balance is reported, so a high reported utilization can affect a score even if the cardholder pays the balance in full soon afterward.
supported · checked Sep 21, 2026Paying credit-card balances in full each month can support credit scores and avoids carrying unnecessary interest-bearing debt.
supported · checked Sep 21, 2026CFPB consumer guidance notes that experts often advise keeping revolving credit use at no more than 30 percent of total available limits, while some guidance suggests even lower usage; 30 percent is a guideline rather than a guaranteed scoring threshold.
