Key Takeaways

  • Credit scores range from 300 to 850, with higher numbers signaling lower lending risk.
  • Payment history is the single largest factor in most scoring models.
  • A score above 670 is generally considered good; above 740 opens more favorable terms.
  • Scores are calculated from data in your credit report, not income or savings.
  • Multiple scoring models exist — lenders may use different versions for different decisions.
  • You can check your credit report for free at AnnualCreditReport.com without affecting your score.

The Score Range and What Each Band Means

The standard credit score scale runs from 300 to 850. Here's how lenders generally interpret each band:

Score RangeCategoryWhat It Signals
800–850ExceptionalVery low risk; often qualifies for best available terms
740–799Very GoodLow risk; typically qualifies for competitive rates
670–739GoodNear or above average; most standard loans accessible
580–669FairSome risk flags; approval possible but at higher rates
300–579PoorHigh risk; limited options, often requiring secured products

These bands aren't hard cutoffs set by any single authority — individual lenders set their own thresholds. A score of 680 might sail through one lender's approval process and fall short at another's. That said, these ranges reflect widely used FICO Score benchmarks and give you a reliable working framework.

716

Average U.S. FICO Score

According to FICO's published data, the average American credit score has held in the 'good' range in recent years.

~49M

Credit-invisible Americans

The Consumer Financial Protection Bureau (CFPB) has estimated that roughly 45–49 million adults have no scoreable credit file.

Weight of payment history in FICO scoring

Payment history is the single largest component of a FICO Score, making on-time payments the most impactful habit you can build.

How Your Score Is Actually Calculated

Your score doesn't come from thin air — it's calculated from data inside your credit report. The five core factors, as defined by the FICO model, are:

  • Payment history (35%): Whether you've paid on time. One missed payment can meaningfully drop your score.
  • Credit utilization (30%): How much of your available revolving credit you're using. Lower is generally better.
  • Length of credit history (15%): How long your accounts have been open. Older accounts help.
  • Credit mix (10%): A variety of account types — cards, loans, mortgage — can help modestly.
  • New credit (10%): Recent applications for credit. Too many in a short window can signal risk.

For a deeper look at each factor and how much it actually moves the needle, see The Five Factors Behind Every Credit Score.

Keep Utilization Below 30% — Lower Is Better

Credit utilization — how much of your available credit limit you're using — accounts for 30% of your FICO Score. If your card limit is $5,000 and your balance is $2,000, your utilization is 40%. Paying down balances or requesting a limit increase (without spending more) can lower that ratio and give your score a meaningful lift. For a full breakdown, see Credit Utilization: The Ratio That Quietly Shapes Your Score.

Why Lenders Care — and What They Do With the Number

From a lender's perspective, your credit score does one thing: estimate the probability that you'll repay what you borrow. A higher score signals lower default risk, which is why it directly influences whether you're approved and at what interest rate.

The stakes are real. On a 30-year mortgage, the difference between a 680 and a 760 score can translate to a meaningfully higher interest rate — and thousands of dollars more in total interest paid over the life of the loan. Lenders also use scores for credit cards, auto loans, and sometimes even rental applications or utility deposits.

It's worth knowing that your score is only one piece of the picture. Lenders also weigh your income, employment status, and debt-to-income ratio before making a final decision.

Reading Your Report: Where the Score Comes From

Your credit score is only as accurate as the data feeding it. That data lives in your credit report — a detailed record of your accounts, payment history, balances, and public records maintained by the three major bureaus: Equifax, Experian, and TransUnion.

Errors in your report can drag your score down unfairly. Federal law gives you the right to dispute inaccuracies, and corrections can sometimes improve your score significantly. You're entitled to a free report from each bureau annually at AnnualCreditReport.com — the only federally authorized source.

You Have More Than One Credit Score

There are dozens of FICO Score versions, plus VantageScore and industry-specific models for auto loans or mortgages. The score a mortgage lender pulls may differ from the one your bank shows you in its app. Don't be alarmed by small differences — what matters more is the trend direction and which band your scores consistently fall into.

Frequently Asked Questions

Generally, a score of 670–739 is considered good, 740–799 is very good, and 800 or above is exceptional. Scores below 580 are typically seen as poor and may limit borrowing options. These ranges are based on common FICO Score benchmarks used by many lenders.
No. Checking your own score is a 'soft inquiry' and has no effect on your score. Only 'hard inquiries' — when a lender pulls your credit as part of an application — can cause a small, temporary dip.
Your score can change whenever your creditors report updated information to the credit bureaus, which typically happens monthly. A single late payment or a sharp rise in card balances can shift your score noticeably within one reporting cycle.
Credit bureaus — Equifax, Experian, and TransUnion — may hold slightly different information depending on what lenders report to each. Scoring models also vary, so a FICO Score and a VantageScore based on the same data can produce different numbers.
Yes. A score is built from any credit account reported to the bureaus — including installment loans like student or auto loans. However, if you have no credit accounts at all, you may be 'credit invisible' with no scoreable file.
Most negative marks — like late payments or collections — remain on your report for seven years. Chapter 7 bankruptcy can stay for up to ten years. The impact on your score typically fades over time, especially as you add positive history.
