Credit utilization ratio is the percentage of your available revolving credit that you're currently using. It's calculated by dividing your total credit card balances by your total credit limits. Credit utilization accounts for 30% of your FICO score — the second most important factor.

How to Calculate Credit Utilization
Credit Utilization = (Total Balances ÷ Total Credit Limits) × 100
Example:
- Card 1: $800 balance, $2,000 limit
- Card 2: $1,200 balance, $5,000 limit
- Card 3: $0 balance, $3,000 limit
- Total balances: $2,000
- Total limits: $10,000
- Utilization = ($2,000 ÷ $10,000) × 100 = 20%
FICO looks at both overall utilization (all cards combined) AND per-card utilization. A single maxed-out card hurts even if your overall utilization is low.

🎯
Not sure which lender fits your credit range?
See who actually approves your score range — and the APR to expect.
The fastest ways to lower utilization: (1) Pay down balances — utilization updates every billing cycle. (2) Request a credit limit increase — more available credit with the same balance = lower utilization. (3) Pay before the statement closes — utilization is measured at statement date, not due date. (4) Become an authorized user on a high-limit card — adds their available credit to your calculation. (5) Open a new card — adds available credit (but only if you can avoid new spending).

Frequently Asked Questions
What is a good credit utilization ratio?
The ideal credit utilization is 1%–10%. Under 30% is the commonly cited guideline, but scores improve significantly as you get below 10%. Keeping utilization at 1%–3% (using your cards but paying almost all of it off) produces the best score results.
Does 0% utilization hurt your credit score?
Slightly. Having 0% utilization (no balance on any card) is slightly worse than 1%–3% utilization. This is because 0% may indicate the card isn't being used, which provides less positive payment history data. However, the difference is small — 0% utilization is much better than 30%+ utilization.
How quickly does credit utilization affect your score?
Credit utilization updates every billing cycle — typically monthly. If you pay down a large balance, your score can improve within 30–45 days once the new balance is reported to the credit bureaus. This makes utilization the fastest factor to change in your credit score.
Does credit utilization reset every month?
Yes. Credit utilization is calculated based on your current balance at the time your statement closes, not a running average. If you pay down your balance before the statement closes, your utilization for that month will reflect the lower balance. There's no memory of past high utilization — only the current snapshot matters.

Focus on the Annual Percentage Rate (APR), which includes both interest and fees. Compare minimum credit score requirements, funding speed, loan amounts, and repayment terms. Read recent customer reviews on Trustpilot and the BBB. Getting pre-qualified lets you see real personalized offers without affecting your credit score.
A score of 670–739 is "good," 740–799 is "very good," and 800+ is "exceptional." Most lenders offer their best rates to borrowers with 720+. If your score is below 670, focus on paying bills on time and reducing credit card balances — these two factors account for 65% of your score.
Credit scores have a dramatic impact on rates. On a $20,000 personal loan, the difference between a 720 score (8% APR) and a 580 score (25% APR) is over $9,000 in additional interest over 5 years. Improving your score before applying can save thousands of dollars.
