If you've ever checked your credit score, you may have seen the term credit utilization. But what does it actually mean, and why does it matter so much? Understanding and managing your credit utilization can be one of the fastest ways to improve your credit score—and keep it healthy for years to come.
What Is Credit Utilization?
Credit utilization is the percentage of your total available credit that you're currently using. In simple terms, it shows lenders how much of your credit you are relying on at a given time.
Example Calculation:
Single Card Example:
Formula: ($300 ÷ $1,000) × 100 = 30%
Multiple Cards Example:
20% utilization
40% utilization
Formula: ($500 ÷ $1,500) × 100 = 33%
Industry Standard:
Credit scoring models, including FICO and VantageScore, generally consider utilization below 30% healthy, while under 10% is ideal for excellent scores.
Why Credit Utilization Matters
Credit utilization accounts for about 30% of your credit score, making it one of the most important factors after payment history. High utilization signals risk to lenders—they may think you rely too heavily on credit or could struggle to pay off debts.
Credit Score Factors Breakdown
Real-World Comparison:
Person A
Credit Limit: $1,000
Balance: $900
90% Utilization
Pays on time but high utilization hurts score
Person B
Credit Limit: $1,000
Balance: $200
20% Utilization
Pays on time with low utilization = higher score
Both pay on time, but Person B will have a significantly higher score due to lower utilization.
Even if you pay your bills on time, maxing out your cards or carrying high balances can lower your score. Learn more about payment history's 35% impact on your credit score.

Tips to Keep Credit Utilization Low
Pay Down Balances Early and Often
Don't wait until the due date. Paying before your statement closes keeps your reported balance lower.
Pro Tip: Make multiple payments throughout the month to keep your balance consistently low.
Spread Spending Across Multiple Cards
If one card is getting close to its limit, use another card to balance your utilization.
Example: Instead of putting $800 on one $1,000 limit card (80% utilization):
- • Put $400 on Card 1 ($1,000 limit) = 40%
- • Put $400 on Card 2 ($1,000 limit) = 40%
- • Overall: $800 / $2,000 = 40% (better than 80%)
Request Higher Credit Limits
If approved, a higher limit increases your total available credit and reduces utilization—just don't increase spending.
Before: $500 balance / $1,000 limit = 50% utilization
After limit increase: $500 balance / $2,000 limit = 25% utilization ✓
Monitor Your Balances Regularly
Tools like credit card apps and credit monitoring services help you stay aware of utilization trends.
Set up balance alerts at 20% and 30% of your credit limit to stay proactive.
Avoid Closing Old Accounts
Old cards increase total credit limit and average account age, both of which help your score.
Why it matters: Closing a $2,000 limit card reduces your total available credit, instantly increasing your utilization percentage.
Special Considerations
Small Balances Count
Even small balances on multiple cards can add up. A $50 balance on five cards equals $250 total utilization.
Timing Matters
Credit scores are updated when creditors report your balances, usually at the statement closing date.
Not Permanent
Utilization isn't permanent. Keeping it low consistently improves scores over time—changes can show in weeks.
