Did you know?

Payment history and credit utilization together account for 65% of your FICO score. Focusing on just these two factors — paying on time and keeping balances low — has the largest impact on your credit score improvement.

Understanding Your FICO Score

Your FICO credit score is a three-digit number between 300 and 850 that lenders use to evaluate your creditworthiness. It determines the interest rates you qualify for on mortgages, auto loans, and credit cards — and can even affect your ability to rent an apartment or get certain jobs. A higher score means lower borrowing costs: the difference between a 680 and a 780 score on a 30-year mortgage could save you tens of thousands of dollars in interest over the life of the loan.

The Five Factors That Determine Your Score

FICO scores are built on five weighted categories. Payment History (35%) is the most important — even a single 30-day late payment can drop your score by 60-110 points. Credit Utilization (30%) measures how much of your available credit you are using; keeping it under 10% earns the best scores. Length of Credit History (15%) rewards long-standing accounts, so think twice before closing your oldest card. Credit Mix (10%) looks at whether you have a variety of account types. New Credit (10%) tracks recent hard inquiries and newly opened accounts.

Quick Wins for Score Improvement

If you want to boost your score quickly, focus on the two largest factors: payment history and utilization. Set up autopay for at least the minimum payment on every account so you never miss a due date. Pay down credit card balances aggressively — going from 50% utilization to under 10% can add 30-50 points. Request credit limit increases (without a hard pull) to lower your utilization ratio without paying anything down. Finally, check your credit reports for errors at AnnualCreditReport.com and dispute any inaccuracies, as roughly 1 in 5 reports contain mistakes that could be dragging your score down.

Frequently Asked Questions

What is a good credit score?+
FICO scores range from 300 to 850. A score of 670-739 is considered Good, 740-799 is Very Good, and 800-850 is Excellent. Most lenders consider 670+ as acceptable for favorable loan terms, though the best rates typically require 740 or above.
How is my credit score calculated?+
FICO scores are based on five weighted factors: Payment History (35%) — whether you pay on time; Credit Utilization (30%) — how much of your available credit you use; Length of Credit History (15%) — how long your accounts have been open; Credit Mix (10%) — variety of account types; and New Credit (10%) — recent inquiries and new accounts.
How can I improve my credit score fast?+
The fastest ways to improve your score are: 1) Pay down credit card balances to lower utilization below 10%, 2) Get added as an authorized user on a family member's old, well-managed card, 3) Dispute any errors on your credit report, and 4) Set up autopay so you never miss a payment. Reducing utilization can show results in as little as 30 days.
Does checking my credit score lower it?+
No. Checking your own credit score is a 'soft inquiry' and does not affect your score at all. Only 'hard inquiries' — when a lender checks your credit for a lending decision — can temporarily lower your score by a few points. You can check your own score as often as you like.
How long do negative items stay on my credit report?+
Most negative items remain on your credit report for 7 years from the date of the first missed payment. Chapter 7 bankruptcies stay for 10 years. Hard inquiries fall off after 2 years but only affect your score for about 12 months. The impact of negative items diminishes over time.
What is credit utilization and why does it matter?+
Credit utilization is the percentage of your available credit that you are using. It is calculated by dividing your total credit card balances by your total credit limits. It accounts for 30% of your FICO score. Experts recommend keeping utilization below 30%, and below 10% for the best scores. Both overall and per-card utilization matter.
