Credit Utilization
Quick Definition
The percentage of available revolving credit currently being used, a major factor in credit score calculations.
Key Takeaways
- Keep credit utilization below 30% — under 10% is ideal for highest scores
- Utilization is calculated both per individual card and across all cards
- Unlike payment history, utilization improvements are reflected immediately
- Closing old credit cards can increase utilization by reducing total available credit
What Is Credit Utilization?
Credit utilization ratio measures how much of your available revolving credit (primarily credit cards) you are currently using. It is calculated by dividing your total credit card balances by your total credit limits. This ratio is the second most influential factor in FICO score calculations, accounting for approximately 30% of the score. Financial experts recommend keeping utilization below 30%, with under 10% being optimal for the highest credit scores. Utilization is measured both per-card and across all cards combined. Unlike most credit factors, utilization has no memory — reducing balances immediately improves your score in the next reporting cycle.
Credit Utilization Example
- 1With a $10,000 total credit limit and $2,500 in balances, your credit utilization is 25%.
- 2Requesting a credit limit increase from $5,000 to $10,000 (without increasing spending) drops utilization from 40% to 20%.
- 3Paying credit card balances before the statement closing date can report 0% utilization even with regular card use.
