How it works

Credit utilization is a plain ratio: total balances ÷ total credit limit × 100. It's calculated the same way whether you're looking at a single card or, as this calculator assumes, your combined balances and limits across every revolving account — enter the totals already summed, since exactly which accounts count varies by scoring model.

The 'where this falls' guidance uses the widely repeated bands from consumer credit-scoring guidance: under 10% is often called ideal, under 30% is the most commonly cited 'stay below this' threshold, 30-50% is a moderate concern, and above 50% is generally flagged as high. These are general, widely published guidelines, not any specific scoring model's exact live formula.

This is a distinct metric from this site's debt-to-income-ratio calculator, which compares recurring monthly debt *payments* to income for loan qualification — credit utilization instead compares revolving *balances* to *limits*, and is one of the most heavily weighted factors in most consumer credit scoring models.

FAQ

Does utilization matter per card or only in total?

Most scoring models weigh both — your overall utilization across all cards, and each individual card's own utilization. A single maxed-out card can hurt your score even if your total utilization looks fine, so this calculator's total-balances view is a useful summary but not the whole picture.

Why is a 0% utilization not necessarily 'best' for a credit score?

Some scoring models treat a very small reported balance (rather than exactly zero) as evidence you're actively and responsibly using credit, so a tiny non-zero utilization sometimes scores marginally better than none at all — though the difference is typically small compared to staying well under the widely cited 30% guideline.
