Credit utilization is responsible for 30% of your FICO score — the second biggest factor after payment history. Most people have never heard of it, which is why it’s one of the most common reasons otherwise responsible people have lower scores than they should.
What credit utilization actually is
Credit utilization is the percentage of your available credit you’re currently using. If your credit card limit is $5,000 and your balance is $2,500, your utilization is 50%.
The formula: Current Balance ÷ Credit Limit = Utilization %
This is calculated both per card and across all your cards combined. Both numbers affect your score.
What percentage you should aim for
Under 30% is the standard advice. Under 10% is better. Under 1% (technically having a balance but paying it off completely before the statement closes) is best.
People with scores above 800 typically have utilization under 7%. The impact is significant — going from 50% utilization to 10% can raise your score by 50–100+ points.
The fastest way to lower your utilization
- Pay down your balance. The most direct fix. Even a partial payment before your statement closing date lowers the number reported to the bureaus.
- Ask for a credit limit increase. Same balance, higher limit, lower utilization percentage — immediately. Call your card issuer and ask. Most will increase your limit after 6–12 months of on-time payments with a single phone call.
- Spread spending across multiple cards. Instead of putting $800 on one card with a $1,000 limit (80% utilization), put $400 on each of two cards with $1,000 limits (40% each, but also 40% combined). The per-card numbers matter too.
- Pay more than once a month. If you pay your balance mid-cycle, before the statement closes, a lower balance gets reported to the bureaus even if you use the card regularly.
One thing most people get wrong
Paying your balance in full each month doesn’t mean zero is reported. Your statement balance — whatever you owe when the billing cycle closes — is what gets reported to the bureaus. If you spend $900 on a $1,000 card but pay it in full when the bill arrives, the bureaus still saw 90% utilization for that month. Pay before the statement closing date if you want to keep utilization low.
