Credit utilization calculator (US)

Work out your overall and per-card credit utilization, and how much to repay to reach a target ratio.

Card 2

A common rule of thumb is to keep the ratio under 30%. Lower is generally better.

Overall credit utilization

23.85%

Low — $1,550 owed against $6,500 of limits.

Highest single card
30%

Scoring models look at this as well as the total.

Utilization is one input among several in a credit-scoring model. No lender publishes a ratio that guarantees an outcome.

Estimate only. This result is produced from the figures you entered and the assumptions listed on this page. It is not financial advice, not a quotation and not an offer, and no provider is bound by it. Check current terms with the provider before acting. Nothing you type here is sent anywhere — the calculation runs entirely in your browser.

How this is worked out

Utilization = total balances ÷ total credit limits × 100

What this assumes

A calculator is only as good as what it leaves out. These are the assumptions built into the result above.

  • Balances are the amounts your card issuers report, which is usually the statement balance rather than what you owe today.
  • Utilization is shown both overall and per card. Scoring models look at both, and weight them differently.
  • Bands are descriptive. No lender publishes a utilization figure that guarantees an outcome.
