Credit Utilization Calculator

FICO describes 'amounts owed' as about 30 percent of a typical score, but that category is broader than revolving utilization and the weighting varies by scorecard. FICO does not publish a guaranteed point gain for moving between utilization levels. Lower reported balances can help, but the effect depends on the full credit file and scoring model.

There is no official universal cutoff at 30 percent or a utilization level that guarantees an 800 score. Lower reported revolving balances are generally associated with lower credit risk, but the effect is continuous and model-dependent. Pay balances according to your budget and avoid interest; do not carry debt solely to produce a score.

Scoring models can consider both aggregate revolving utilization and balances on individual accounts. Their formulas and thresholds are proprietary, so this calculator's 90 percent warning is an internal signal, not an official FICO rule. Paying down a high-balance card may help, but no point increase is guaranteed.

Many issuers report a statement balance, but reporting dates and bureau practices vary. A payment before the reported balance is sent can lower utilization shown on the report, while the due date controls whether a payment is on time and whether interest may apply. Check the issuer and credit reports rather than assuming one universal date, and do not expect a guaranteed score increase.

A scoring model may treat a nearly maxed individual account as additional risk even when aggregate utilization is lower. The size of that effect is proprietary and depends on the rest of the file. Moving a balance can add fees or change promotional terms, so compare cost and payoff risk instead of optimizing only for a modeled score.
