A credit score is a three-digit number, most commonly from 300 to 850, that summarizes information in your credit report to estimate how likely you are to repay borrowed money as agreed. Lenders — and sometimes landlords and insurers — use it as one input when deciding whether to approve you and what terms to offer. It is not a grade of your worth or total financial health: it says nothing directly about your income, savings, or net worth.
Key Takeaways
– Most widely used scores — base FICO Scores and VantageScore — run from 300 to 850. Higher is better.
– You do not have one credit score. You have many, because there are three bureaus, multiple score versions, and industry-specific models.
– For a general FICO Score, the five factor categories are: payment history (35%), amounts owed (30%), length of credit history (15%), new credit (10%), and credit mix (10%).
– These percentages are general-population guidelines published by FICO. The exact impact varies by person.
– A score is only as accurate as the credit report behind it — which is why checking your free annual credit report comes first.
Where Your Credit Score Comes From
Three nationwide credit bureaus — Equifax, Experian, and TransUnion — each maintain a credit report on you, built from information lenders report to them. Scoring companies such as FICO and VantageScore apply models to a bureau’s data and produce a number. Because the bureaus may hold slightly different data and many model versions exist, the same person can legitimately see several different scores on the same day. A bank app might show a VantageScore based on TransUnion data, while a mortgage lender pulls FICO versions from all three bureaus. Neither is “wrong” — they are different lenses on similar information.
Credit Score Ranges
FICO labels the base range as follows:
| FICO Score range | Rating | What it generally signals |
|---|---|---|
| 300–579 | Poor | Significant difficulty repaying in the past; approvals are hard to get and expensive when offered |
| 580–669 | Fair | Below-average history; many lenders will consider you, often with higher rates or deposits |
| 670–739 | Good | Near or slightly above the average of U.S. consumers; most lenders consider this acceptable |
| 740–799 | Very Good | A dependable track record; better-than-average rates are commonly available |
| 800–850 | Exceptional | The top tier; the strongest rates and terms are generally available |
VantageScore uses the same 300–850 span but groups scores differently; for VantageScore 3.0, 781–850 is often labelled excellent, 661–780 good, 601–660 fair, 500–600 poor, and 300–499 very poor. Labels vary by version and provider, so treat them as rough translations. There is also no single minimum score that guarantees or blocks approval — each lender sets its own standards and weighs income, debts, and collateral too.
The Five FICO Score Factors
FICO publishes the general importance of five categories for its general-purpose scores. The percentages below are population-level guidelines, not a formula you can run in reverse.
1. Payment history — 35%
Whether you pay as agreed is the largest category. It considers on-time and late payments; how late a payment was (30, 60, 90+ days); and how recently and how often it happened. Severe public records such as bankruptcies also appear here. A recent 30-day late payment usually matters more than an isolated one from six years ago.
2. Amounts owed — 30%
This category looks at how much you owe overall and, for revolving credit, how much of your available limit you are using — your utilization. If you carry a $1,700 total balance against $10,000 of total card limits, your overall utilization is:
$1,700 ÷ $10,000 × 100 = 17%
Models can consider both overall utilization and the utilization on each individual card, so one nearly maxed-out card can matter even when the total looks fine. Our dedicated guide covers the math and the practical levers: Credit Utilization Ratio: Formula & Ways to Lower It.
3. Length of credit history — 15%
This includes the age of your oldest account and the average age of all accounts. A longer history gives models more data. You cannot manufacture age — one reason opening many new accounts at once can drag this category down, by lowering your average age.
4. New credit — 10%
Recent activity matters: accounts opened lately and hard inquiries from the last 12 months. FICO generally treats rate-shopping for a mortgage, auto, or student loan within a focused window as a single inquiry; opening several credit cards in a short span is treated differently and can signal higher risk.
5. Credit mix — 10%
Models consider the variety of credit you manage — for example credit cards (revolving) alongside a mortgage, auto loan, or student loan (installment). Mix is a small category: it is not worth taking a loan you do not need just to add a type.
How VantageScore Differs
VantageScore, created jointly by the three bureaus, weighs information differently — in recent versions, payment history is most influential, followed by factors such as age and mix of credit, utilization, balances, and recent behaviour, with available credit carrying the least weight. The practical takeaway is the same for both systems: pay on time, keep revolving balances low relative to limits, and apply for new credit sparingly.
Worked Example: What One Late Payment and One Balance Change Can Do to the Inputs
Scores come from proprietary models, so no article can honestly tell you a change is “worth X points.” What can be shown is how the inputs change. Consider a hypothetical borrower, Maya, with two cards: Card A, $450 balance on a $1,500 limit (30% utilization), and Card B, $0 on a $3,500 limit — overall, $450 ÷ $5,000 = 9%.
In one month, her reported Card A balance falls after a payment, improving the amounts-owed input — but a store card payment is also reported 30 days late, adding a fresh negative to payment history, the largest category at 35%, where recent lates weigh most. That is why experienced borrowers protect payment history first and treat utilization as a secondary lever.

Common Misconceptions
“I have one credit score.” You have many — three bureaus, multiple FICO and VantageScore versions, and industry-specific scores such as auto and bankcard versions (which can use a 250–900 range). Expect variation, and watch the trend of the underlying report data rather than one number.
“Checking my own score hurts it.” It does not. Checking your own report or score is a soft inquiry and has no score impact. See Soft Inquiry vs. Hard Inquiry.
“I must carry a balance to build credit.” You do not. Carrying a balance usually means paying interest, and interest paid is not a scoring factor. Using a card lightly and paying in full builds history without the cost.
“Keeping utilization under 30% is a magic rule.” The 30% figure is a widely cited guideline, not a cliff in the models. Lower reported utilization is generally better; treat 30% as a ceiling, not a target.
“My income is part of my score.” Income is not in your credit report and is not a scoring factor. Lenders may ask about it separately on an application — but a raise does not, by itself, change a score.
“Closing old cards always helps.” Closing a card removes its limit from your total available credit, which can raise your overall utilization. Sometimes closing still makes sense — an annual fee you cannot justify, for example — but it is a trade-off, not a free win.
“A higher score means I am wealthy.” A person with modest income and well-managed accounts can have an exceptional score; a high earner with large balances and missed payments can have a poor one. Scores measure credit behaviour only. Building savings is a separate job — see our guide to a high-yield savings account.
Frequently Asked Questions
What is a good credit score?
Under FICO’s labels, 670–739 is “good” and 740 and above is “very good” or “exceptional.” Many lenders reserve their best rates for the mid-700s and above, but standards differ by lender and product, and a high-600s score can still qualify for many mainstream products.
How often does a credit score change?
A score is calculated when requested, using the report data available at that moment. Because lenders typically report activity about once a month — often around the statement closing date — scores commonly move month to month as balances and payments post.
Why is my score different on different websites?
Different sites may use different bureaus, models (FICO vs. VantageScore), model versions, and update dates. Small differences are normal; large ones are a reason to compare the underlying reports for errors.
Can I have no credit score at all?
Yes. With little or no recent credit history, a model may not be able to generate a score. FICO generally needs at least one account open for six months or more and at least one account reported in the past six months.
Do employers check my credit score?
No — employers who run background checks generally review a modified credit report, with your written permission, not your score. Some states restrict the practice.
Bottom Line
A credit score is a compressed summary of your credit report, produced by a model, at a moment in time. The ranges run 300–850 for common scores, and the biggest levers are timeless: pay on time (35%), keep revolving balances low relative to limits (30%), and let a clean history age.
