Where to go next:
A credit score is a number that estimates your credit risk—how likely you are to repay on time. Lenders use it to decide approval, interest rate (APR), limits, and deposits.
This guide explains what a credit score is, what affects it most, and why scores change even when you feel like you did “nothing.”
Quick answer / Key takeaways
- A credit score is a risk score, not a “wealth score.”
- The biggest drivers are usually payment history and credit utilization.
- Scores can change because of statement balances, new accounts, hard inquiries, or late payments.
- Checking your own score typically does not hurt it: how to check credit score.
- For the fastest short-term wins, start here: credit utilization.
What a credit score is (in one sentence)
A credit score is a model-based estimate of your likelihood to repay, based on what’s in your credit reports.
Where your credit score comes from
Your score is calculated from your credit report data—accounts, balances, payment history, and recent credit activity.
If you haven’t checked your reports lately, start there: how to check credit reports.
Credit score factors explained (what actually moves the needle)
1) Payment history
On-time payments help. Late payments and serious delinquencies can hurt the most.
If you’re dealing with late marks, use realistic options: remove late payments.
2) Credit utilization (balances vs limits)
High utilization can drag scores down even if you pay on time.
Tactics and timing: credit utilization.
3) Length of credit history
Older, well-managed accounts can help because they show stability. Closing an old card can raise utilization and sometimes backfire.
4) New credit activity (hard inquiries + new accounts)
Applications and new accounts can cause short-term drops.
Details: hard inquiries.
5) Credit mix
Mix can help a little, but it’s not worth forcing. Don’t take debt you don’t need just to “build credit.”
What affects a credit score most (and what to do)
| Factor | What it means | Common score impact | Best move |
|---|---|---|---|
| Payment history | On-time vs late payments | Biggest | Set autopay for at least the minimum; prevent new late marks; dispute only real errors. |
| Credit utilization | Card balances vs credit limits | Big | Lower reported balances; pay before statement date; keep balances low on reporting day. |
| New credit | Hard inquiries + new accounts | Medium | Apply only when needed; avoid multiple applications close together. |
| Length of history | Age of your accounts | Medium | Keep older accounts open if affordable; don’t close your oldest card without a reason. |
| Credit mix | Cards + installment loans | Small | Don’t force it; focus on payment history + utilization first. |
Why your credit score changes (even when you “did nothing”)
Statement balance timing
Many cards report around statement closing. If a high balance reports, your score can dip even if you pay later.

Utilization moves month to month

Fast wins: credit utilization.
New inquiry or new account posted

Common mistakes
- Paying interest “to build credit” (you don’t need to).

- Disputing everything instead of targeting real errors.
- Opening too many accounts quickly.
- Falling for “tradeline” shortcuts without understanding risks: authorized user credit.
