Find your credit utilization — balances as a percent of limits — and how much to pay down to hit a healthier ratio.
Credit utilization is one of the largest factors in a credit score. Both per-card and overall ratios matter; under 30% is a common guideline, under 10% is ideal. This doesn't calculate a score — scoring models are proprietary. General information only.
Credit utilization — how much of your available credit you're using — is one of the biggest levers on a credit score, second only to payment history. Lower is better: under 30% is the common rule, under 10% is ideal. It's calculated both per card and across all your cards.
Utilization = total balances ÷ total credit limit
Not always — issuers report the statement balance, so a balance can show even if you pay in full. Paying before the statement closes lowers the reported figure.
Usually no — closing it removes that limit and can raise your overall utilization, hurting your score. Keeping it open (and unused) helps.
