A credit score is a three-digit summary of the information in one of your credit reports, designed to predict how likely you are to repay borrowed money as agreed. Lenders use it to decide whether to approve you and at what price. Landlords, insurers (where allowed), and others may use scores or reports too.
Most confusion about scores comes from one fact people don't hear enough: you don't have one credit score. You have many, and they're all built from your reports. Fix the report and the scores follow.
Key takeaways
- Scores are calculated from your credit report data at a moment in time. Change the data, and the score changes.
- FICO and VantageScore base scores generally range from 300 to 850; higher is better.
- You have many scores: one per bureau, per model, per version.
- Payment history and amounts owed carry the most weight in FICO Scores (about 35% and 30%).
- Scores don't consider income, race, religion, national origin, sex, marital status, or checking your own credit.
What a credit score is
The CFPB describes a credit score as a prediction of your credit behavior, such as how likely you are to pay a loan back on time, based on information from your credit reports (CFPB). Scoring companies build models from large sets of anonymized credit data, find patterns that predict repayment, and turn those patterns into a formula.
The most widely used model families are FICO and VantageScore. Their base scores generally range from 300 to 850 (FICO). What counts as good is up to each lender, but FICO publishes general ranges; see what is a good credit score.
Why you have dozens of scores
- Three bureaus. Equifax, Experian, and TransUnion each keep their own file, and they don't always match (why).
- Multiple models and versions. FICO and VantageScore each have several versions in use. Lenders upgrade on their own schedules, so older versions stay in use for years.
- Industry-specific scores. Auto and bankcard versions are tuned for those lending decisions and can use different ranges.
- Timing. A score is a snapshot. A balance reported yesterday changes today's score.
That's why the score in an app may not match the one a lender sees. Watch the direction over time and the underlying report, not any single number.
The five factors behind FICO Scores
FICO publishes the general weight of each category for the general population (FICO):
| Factor | Approx. weight | What it looks at |
|---|---|---|
| Payment history | 35% | On-time vs. late payments, collections, bankruptcies |
| Amounts owed | 30% | Balances, especially revolving utilization |
| Length of credit history | 15% | Age of oldest, newest, and average accounts |
| New credit | 10% | Recent accounts and hard inquiries |
| Credit mix | 10% | Variety, such as revolving and installment accounts |
Your own profile may weigh these differently. A deeper walk-through is in the 5 credit score factors. VantageScore uses comparable categories with its own weighting; the same habits help under both.
What scores don't consider
- Your income, salary, or employment (though lenders may consider these separately).
- Your race, color, religion, national origin, sex, or marital status. The Equal Credit Opportunity Act prohibits creditors from considering these in credit decisions.
- Where you live.
- Soft inquiries, like checking your own credit or prescreened offers.
- Whether you're working with a credit service.
What moves fast, what moves slow
| Change | Typical speed | Why |
|---|---|---|
| Lower reported card balances | As soon as the next balance is reported | Utilization is a current-state measure in most models |
| Correcting an inaccurate negative item | After the dispute resolves and the report updates | The score recalculates from the corrected data |
| New hard inquiry | Small dip that fades; FICO counts the last 12 months | Inquiries age out of the scoring window |
| A new late payment | Can drop quickly; recovers slowly | Payment history is the heaviest factor |
| Building history | Months to years | Account age and consistent payments accumulate |
Nobody can honestly promise a specific score or point change. Results vary by file.
How lenders use your scores
A score is usually one input, not the whole decision. Lenders often use score cutoffs to decide whether to approve an application and score tiers to set the interest rate, then layer in other information such as income, existing debts, and the details in your report. If a lender offers you worse terms based on your report, you may receive a risk-based pricing or adverse action notice that explains which bureau's report was used and how to get a free copy (FCRA rights).
That's why two people with the same score can get different offers, and why the same person can get different offers from different lenders. Comparing offers matters as much as the number.

- 2Dispute anything inaccurate, incomplete, or unverifiable. It's free; here's how.
- 3Never miss a payment. Autopay the minimum on every account as a backstop.
- 4Lower revolving balances, especially before statement closing dates. The calculator gives you the exact dollars.
- 5Apply for new credit only when needed, and rate-shop within short windows.
- 6Add positive history if your file is thin, with a secured card or credit-builder loan.
- 7Let time work. Negative items weigh less as they age.
Common score myths
- "Checking my credit lowers my score." No. Checking your own credit is a soft inquiry.
- "I need to carry a balance to build credit." No. Paying in full builds payment history without interest.
- "Closing old cards helps." Often the opposite: it can raise utilization and, over time, shorten average age.
- "Paying a collection removes it." Not automatically; it should update to $0. Some newer models ignore paid collections (details).
- "Income affects my score." No, though lenders may consider it separately.

Frequently asked questions
What is the range for credit scores?
FICO and VantageScore base scores generally range from 300 to 850. Some industry-specific scores use different ranges.
Why is my credit score different everywhere I look?
Different bureaus, different scoring models and versions, and different timing. Each score reflects one bureau's file at one moment, calculated one way.
Which credit score do lenders use?
It depends on the lender and product. Many use a version of FICO; some use VantageScore; mortgage and auto lenders often use specific versions. Ask the lender.
How often do credit scores update?
Whenever the underlying report changes, which can be multiple times a month as different creditors report. A score is calculated when it's requested.
Does my income affect my credit score?
No. Income isn't in your credit report. Lenders may still consider it when deciding on an application.
Can anyone promise to raise my credit score by a set amount?
No. Scores depend on the information in your reports and how models weigh it. Be wary of anyone promising a specific score or point increase.
Do I have a credit score if I've never used credit?
Possibly not. Scoring models need enough reported history to calculate a score, so people with no accounts or very new accounts may not have one yet. See how to build credit from scratch.
Will paying off a loan early raise my score?
Not necessarily. Paying off an installment loan reduces debt, which is good for your finances, but closing it can slightly change your credit mix. Effects vary by file and are usually small either way.
