A credit score is a three-digit number, typically ranging from 300 to 850 under the widely used FICO model, that summarizes how risky you appear as a borrower based on your credit history. Lenders, landlords, and sometimes insurers use it to decide whether to extend credit and on what terms.
The score is calculated from information in your credit reports — payment history, amounts owed, length of credit history, new credit, and credit mix — and it can shift up or down over time as that information changes.
What factors make up a credit score?
Under the common FICO breakdown, payment history accounts for about 35% of the score, amounts owed (including credit utilization) about 30%, length of credit history about 15%, new credit about 10%, and credit mix about 10%.
This weighting means a single missed payment can hurt more than opening one new account, and it explains why paying on time consistently is usually the single biggest lever for improving a score.
What is a good credit score?
Under the FICO scale, scores are commonly categorized roughly as: below 580 poor, 580-669 fair, 670-739 good, 740-799 very good, and 800-850 exceptional. Borrowers in the 'good' range and above generally qualify for more favorable interest rates.
The practical difference can be significant: a borrower with a 760 score might qualify for a mortgage rate a full percentage point lower than a borrower with a 640 score, which on a $300,000 30-year loan can mean tens of thousands of dollars in extra interest over the loan's life.
How to build or improve a credit score
Common, generally accepted steps include paying every bill on time, keeping credit card balances low relative to limits, avoiding opening many new accounts in a short period, and keeping older accounts open to preserve credit history length.
Improvement isn't instant — meaningful score changes typically play out over months as new payment history and utilization data get reported, rather than overnight.
How each FICO factor is weighted and why
Payment history (about 35%) carries the most weight because it's the strongest statistical predictor of future default risk: someone who has paid on time for years is far less likely to miss a payment than someone with recent delinquencies. Even one payment 30+ days late can lower a score by anywhere from roughly 60 to over 100 points depending on the starting score, with higher starting scores typically seeing larger drops.
Amounts owed (about 30%) is driven largely by credit utilization, which is why paying down revolving balances tends to move a score faster than most other actions. Length of credit history (about 15%) rewards older accounts and average account age, new credit (about 10%) reflects recent inquiries and newly opened accounts, and credit mix (about 10%) modestly rewards experience managing different account types, such as a mix of credit cards and installment loans.
How fast can a credit score recover after damage?
Recovery time depends on the type of negative event. A single late payment's impact typically fades over several months to about two years, even though the record itself can stay on a credit report for up to seven years. A collections account or charge-off can weigh on a score for a longer stretch, though its effect also lessens over time even before it's removed from the report.
More severe events take longer: recovering from a bankruptcy, which can remain on a report for up to 7-10 years depending on the chapter filed, often takes several years of consistent on-time payments and low balances before a score returns to a 'good' range, though some borrowers see meaningful rebuilding progress within 1-2 years of disciplined credit use.
Common mistakes
- Believing checking your own credit score lowers it — this is a 'soft inquiry' and does not affect your score.
- Thinking closing old, unused credit cards always helps — it can shorten credit history and raise utilization, potentially hurting the score.
- Assuming income is a factor in the credit score — it is not directly included in FICO or VantageScore calculations.
- Expecting one on-time payment to immediately erase the effect of a previous late payment.
- Assuming a single derogatory mark like a collection account will disappear from a score's impact as fast as it disappears from view.

How often does my credit score update?
Scores can update whenever a lender reports new information to the credit bureaus, which commonly happens monthly, so your score can change from month to month.
Do I have one credit score or several?
You typically have multiple scores, since there are different scoring models (like FICO and VantageScore) and three major credit bureaus, each of which may report slightly different information.
Does a hard inquiry hurt my credit score a lot?
A single hard inquiry, such as applying for a new credit card, typically lowers a score by only a few points and the effect fades within a year or so.
Can I have a good credit score with no debt at all?
It's difficult, because scoring models need some credit history to evaluate, so having no credit accounts at all often results in no score or a limited one, sometimes called 'credit invisible.'
How long do late payments stay on a credit report?
A late payment can generally remain on a credit report for up to seven years, though its negative impact on the score tends to lessen over time.
