Credit Utilization Calculator — Hit the Sweet Spot for Your Score

You want to know exactly how much to pay down before your statement cuts to maximize your score.

The utilization thresholds FICO actually uses

Under 10% = max score. 10-29% = good. 30-49% = noticeable penalty. 50-74% = significant penalty. 75-100% = severe penalty. Plus: any single card maxed (>90%) is penalized even if your overall utilization is low.

The math: how to calculate yours

Per-card: (statement balance / credit limit) × 100. Overall: (sum of all balances / sum of all limits) × 100. FICO checks BOTH — so a $9,500 balance on a $10,000 card plus $0 across five other cards still hurts you, even if overall utilization is 19%.

Timing the payment for max impact

Lenders report your balance on the statement closing date — not the due date. Pay your card down to <10% BEFORE the statement closes, and the lower number is what FICO sees. This single trick adds 20-40 points in one cycle with no other changes.

Frequently asked questions

Should I pay my card to $0?

No — leave $5-25 on one card. A zero across all cards can trigger 'no activity' scoring and cost 5-10 points.

What if I have a $0 statement on every card?

FICO may show 'no recent revolving activity' which slightly lowers your score. Always have ONE card show a small statement balance.

Does utilization on a charge card (Amex) count?

Most Amex charge cards no longer report utilization to bureaus. Check before relying on this.
