What Is a Credit Score?
A credit score is a three-digit number, typically ranging from 300 to 850 in the US, that represents how reliably you have managed debt in the past. Lenders use it as a quick indicator of risk: how likely are you to repay a new loan on time?
The most widely used scoring model is the FICO Score, though VantageScore is also used by some lenders. Both use similar inputs but weight them slightly differently. When a lender says they check your credit score, they are almost certainly using one of these two models.
Credit Score Ranges
| Score Range | Band | What It Generally Means |
|---|---|---|
| 800 – 850 | Exceptional | Access to the best rates and terms from most lenders |
| 740 – 799 | Very Good | Strong borrowing options, minor limitations |
| 670 – 739 | Good | Qualifies for most mainstream loan products |
| 580 – 669 | Fair | Options exist but rates are higher and choices narrower |
| 300 – 579 | Poor | Limited options; specialist lenders only; higher rates and stricter terms |
These ranges are general indicators based on FICO scoring. Lenders apply their own criteria and thresholds independently, a score in any band does not guarantee or preclude approval.
How Your Credit Score Is Calculated
FICO calculates your score using five weighted factors. Understanding each one can help you identify where you have room to improve:
The single biggest factor. Whether you have paid past credit accounts on time. Late payments, defaults, and collections have a significant negative impact.
How much of your available credit you are using. Keeping utilisation below 30%, ideally below 10%, is generally recommended. High balances relative to your limits signal financial stress to lenders.
How long your accounts have been open. Older accounts, even unused ones, generally help your score. Closing old accounts can shorten your average account age.
Having a variety of credit types (credit cards, installment loans, mortgage) can help your score modestly. However, opening accounts just to diversify is rarely worth it.
Each new credit application triggers a hard inquiry, which can temporarily lower your score by a few points. Multiple applications in a short period can signal financial difficulty to lenders.
Hard vs. Soft Credit Inquiries
Not all credit checks are equal. Understanding the difference matters, especially if you are shopping around for a loan.
| Type | What Triggers It | Affects Score? | Visible To Lenders? |
|---|---|---|---|
| Hard Inquiry | Applying for a loan, credit card, or mortgage | Yes, small, temporary drop | Yes |
| Soft Inquiry | Checking your own score; pre-qualification checks | No | No |
Rate shopping for a mortgage or auto loan within a short window (typically 14–45 days depending on the scoring model) is usually treated as a single hard inquiry.
What Does NOT Affect Your Credit Score
Common misconceptions worth clearing up. The following have no impact on your FICO score:
- Your income or employment status
- Your bank account balance
- Soft inquiries (checking your own score)
- Where you live or how long you have lived there
- Your age or marital status
- Utility, rent, or phone payments (unless reported to credit bureaus via specialist services)
How to Check Your Credit Score
You are entitled to a free credit report from each of the three major bureaus, Experian, Equifax, and TransUnion, once per year via AnnualCreditReport.com (the official US government-mandated site). Many banks and credit card providers also offer free FICO or VantageScore access within your account dashboard.
Checking your own score is a soft inquiry, it has no effect on your score.
How Your Score Affects Borrowing
Your credit score directly influences:
- Whether a lender will consider your application
- The interest rate you are offered, a higher score typically means a lower rate
- The loan amount you may be eligible for
- The terms and conditions, including repayment flexibility
Even a modest improvement in your credit score, say, from 650 to 700, can meaningfully reduce the interest rate offered on a loan, saving hundreds or thousands of dollars over the repayment period.
