Understanding Credit Scores: What They Are and How to Improve Yours
Understand how credit scores work, what factors affect them, and actionable strategies to raise your score. Covers FICO and VantageScore models.
What Is a Credit Score
A credit score is a three-digit number, typically ranging from 300 to 850, that summarizes your creditworthiness. Lenders use it to decide whether to approve you for credit cards, loans, and mortgages, and at what interest rate. The two main scoring models are FICO (used by about 90 percent of lenders) and VantageScore. Both draw data from your credit reports at the three major bureaus — Equifax, Experian, and TransUnion. A higher score signals lower risk to lenders and unlocks better terms, potentially saving you tens of thousands of dollars over a lifetime of borrowing.
Credit Score Ranges and What They Mean
FICO scores break down into five tiers: Exceptional (800 to 850), Very Good (740 to 799), Good (670 to 739), Fair (580 to 669), and Poor (300 to 579). A score above 740 generally qualifies you for the best interest rates on mortgages and auto loans. Borrowers with scores below 620 often face subprime rates or may be denied credit altogether. Even a 40-point improvement — say from 680 to 720 — can save you 0.5 percent or more on a mortgage rate, which translates to thousands of dollars over a 30-year loan.
The Five Factors That Determine Your Score
FICO weighs five categories: payment history (35 percent) — whether you pay on time; credit utilization (30 percent) — how much of your available credit you use; length of credit history (15 percent) — the age of your accounts; credit mix (10 percent) — diversity of account types; and new credit inquiries (10 percent) — how often you apply for credit. Payment history and utilization together account for nearly two-thirds of your score, so focusing on on-time payments and low balances delivers the fastest improvement.

How to Improve Your Credit Score
Pay every bill on time — set up autopay for at least the minimum payment on all accounts. Reduce your credit utilization below 30 percent; ideally below 10 percent. If you have high balances, consider requesting a credit limit increase (without increasing spending) to lower your utilization ratio. Avoid closing old accounts because they contribute to your average account age. Dispute any inaccuracies on your credit reports — studies show one in five consumers have errors that could affect their scores. Become an authorized user on a family member's long-standing, well-managed account to add positive history.
Common Credit Score Myths
Checking your own credit score does not hurt it — that is a soft inquiry, not a hard one. Carrying a balance on your credit card does not help your score; paying in full each month is better. Closing a credit card you no longer use can actually lower your score by reducing available credit and shortening your average account age. Income is not a factor in your credit score, although lenders may consider it separately. Finally, there is no single universal credit score — you have dozens of FICO and VantageScore variants, and each lender may see a slightly different number.

Frequently Asked Questions
How often does my credit score update?
Credit scores update whenever a lender or creditor reports new information to one of the three bureaus, which typically happens once per billing cycle — roughly every 30 to 45 days. If you pay down a large balance, it may take one to two billing cycles for the new balance to appear and your score to reflect the change.
Does checking my credit score lower it?
No. Checking your own score is a soft inquiry and has zero impact. Hard inquiries, which occur when a lender pulls your credit as part of a loan or credit application, can lower your score by a few points temporarily. Multiple hard inquiries for the same type of loan within a 14- to 45-day window are grouped as a single inquiry.
How long do negative items stay on my credit report?
Most negative items — late payments, collections, charge-offs — remain on your credit report for seven years from the date of the first missed payment. Chapter 7 bankruptcy stays for 10 years. The impact diminishes over time, and many scoring models weight recent activity more heavily than older negative marks.
