Credit utilization is the second most important factor in your credit score, accounting for approximately 30% of your FICO score. It measures how much of your available revolving credit you are currently using.
The Formula
Credit Utilization = (Total Balances ÷ Total Credit Limits) × 100
For example, if you have $2,000 in balances across all credit cards and a combined credit limit of $10,000, your utilization is 20%.
Why Utilization Matters to Credit Scores
Lenders view high utilization as a sign of financial stress. A person using 80% of available credit is spending more than they can easily repay and may be a higher default risk. Low utilization signals that you manage credit responsibly and are not dependent on it.
Target Utilization Rates
| Utilization | Impact on Credit Score |
|---|---|
| 0–9% | Excellent — maximum score benefit |
| 10–19% | Very good |
| 20–29% | Good |
| 30–49% | Average — may start to lower your score |
| 50–74% | Poor — significant negative impact |
| 75–100% | Very poor — serious score damage |
Per-Card vs. Overall Utilization
FICO calculates utilization both overall (all cards combined) and per-card (each card individually). Even if your overall utilization is low, a single card at 90% can damage your score. Ideally, keep each individual card below 30%.
Reporting Date Timing
Credit card balances are reported to credit bureaus on your statement closing date — not your payment due date. Even if you pay in full each month, a high balance on your statement date hurts your score. Paying down balances before the statement closes can immediately improve your utilization.
How to Lower Utilization
- Pay down balances (most direct method)
- Request a credit limit increase (spreads the same balance across more credit)
- Open a new credit card (adds more available credit — but triggers a hard inquiry)
- Pay your balance multiple times per month
