Your credit score is built from five specific categories of information in your credit report, weighted differently by importance
Your credit score is a three-digit number that lenders use to decide whether to lend you money and at what interest rate. It comes from five measurable pieces of your financial history, each carrying a different weight. Understanding what goes into that number helps you see where changes will have the most impact on your borrowing costs.
The five categories are: payment history, amounts owed, length of credit history, credit mix, and recent inquiries. They do not carry equal weight. Payment history alone accounts for roughly 35 percent of your score, while the others range from 10 to 30 percent. This means missing a payment hurts far more than opening a new credit card, but both matter.
Key Takeaways
- Payment history — whether you pay on time — makes up about 35 percent of your score and has the largest single impact on your number.
- Amounts owed (your credit utilization) accounts for roughly 30 percent; using less of your available credit raises your score more than having zero balances.
- Length of credit history counts for about 15 percent; older accounts help your score even if you do not use them, so closing old cards can lower it.
- Credit mix — having different types of credit like cards, loans, and mortgages — makes up about 10 percent of your score.
- Recent inquiries and new accounts account for roughly 10 percent; hard inquiries drop your score slightly for a few months, but the impact fades.
Payment History: 35 Percent of Your Score
Payment history is the single largest factor in your credit score. It measures whether you pay your bills on time, every time. A late payment — even one that is 30 days overdue — stays on your credit report for seven years and damages your score when ready. The later the payment, the worse the damage: a 90-day late payment hurts more than a 30-day one.
What counts as payment history is not just credit cards. It includes auto loans, mortgages, student loans, medical bills sent to collections, and utility payments if they are reported to the credit bureaus. One missed payment can lower your score by 100 points or more, depending on how high your score was before the miss. If you have a strong payment history, a single late payment does less damage than it would to someone with a weaker record.
Payments reported as on-time stay on your record indefinitely, so the longer you maintain a clean payment history, the more it protects you. A single late payment from five years ago matters less than one from last month, but both still count.
Amounts Owed: 30 Percent of Your Score
Credit utilization — the percentage of your available credit that you are actually using — makes up about 30 percent of your score. If you have a credit card with a $5,000 limit and a $1,500 balance, your utilization on that card is 30 percent. The lower your utilization across all your cards, the higher your score tends to be.
Most scoring models prefer utilization below 30 percent, and below 10 percent is even better. This does not mean you should carry zero balances. A card with zero balance and zero activity can actually hurt your score slightly because it shows no recent payment history. The ideal is a small balance that you pay off in full or nearly in full each month.
Utilization is calculated both per card and across all your cards combined. If one card is maxed out but your overall utilization is low, that maxed card still drags down your score. Paying down high-balance cards before explore for a loan or mortgage can raise your score noticeably in a matter of weeks, since utilization changes are reported monthly.
Length of Credit History: 15 Percent of Your Score
Length of credit history measures how long your credit accounts have been open. It includes the age of your oldest account, the age of your newest account, and the average age of all your accounts. The longer your history, the higher this component of your score.
This is why closing old credit cards can lower your score even if you pay them off. When you close a card, it stops aging, and your average account age drops. An account you opened 15 years ago and never use still helps your score by existing. If you want to close a card, closing a newer one does less damage than closing an old one.
If you are new to credit, this category works against you temporarily. There is no way to speed up time, but you can avoid making it worse by keeping old accounts open and active. Even a small purchase every few months keeps an account from looking dormant.
Credit Mix: 10 Percent of Your Score
Credit mix refers to the variety of credit types you hold. Credit bureaus track revolving credit (credit cards, lines of credit) separately from installment credit (auto loans, mortgages, personal loans). Having both types shows lenders you can manage different kinds of debt.
Credit mix accounts for only 10 percent of your score, so it should not drive your decisions. You should not take out a loan just to improve your mix. However, if you have only credit cards and no installment loans, your score may be slightly lower than it would be with a mix. Conversely, if you already have a mortgage and an auto loan, adding another credit card will not meaningfully improve your score.
The impact of credit mix is most noticeable for people with very limited credit history. Someone with one credit card and nothing else may see a small boost from adding a different type of credit, but the effect is modest compared to the impact of payment history or utilization.
Recent Inquiries and New Accounts: 10 Percent of Your Score
When you explore for credit, the lender performs a hard inquiry — a check of your credit report. Hard inquiries lower your score by a few points and stay on your report for two years, though their impact fades after a few months. Multiple hard inquiries in a short time (within 14 to 45 days, depending on the scoring model) often count as a single inquiry, so shopping for a mortgage or auto loan in a short window does not multiply the damage.
New accounts also affect this category. Opening a new credit card lowers your score slightly because it lowers your average account age and adds a hard inquiry. The impact is temporary. After six months to a year of on-time payments, the new account becomes less of a drag on your score.
Soft inquiries — checks you run yourself, or checks a company runs to see if they want to offer you credit — do not affect your score at all. Checking your own credit report or getting a pre-qualification offer does not lower your number.
How These Factors Work Together
Your credit score is not a straightforward sum of these five categories. The scoring model weighs them together in ways that can interact. For example, a strong payment history can offset a high utilization rate somewhat, but not entirely. A long credit history helps, but it cannot make up for recent late payments.
The most direct path to a higher score is consistent on-time payments and lower utilization. These two factors alone make up 65 percent of your score. Improvements in these areas show up in your score within one to two months. Changes to length of history, credit mix, and inquiries happen more slowly or are harder to control, so they should not be your focus if you are trying to raise your score quickly.
Frequently Asked Questions
Does paying off a credit card balance hurt my score?
Paying off a balance lowers your utilization, which raises your score. The only downside is if you close the card afterward, which removes an account from your history. If you pay off the balance and keep the card open, your score will improve.
How long does a late payment stay on my credit report?
A late payment stays on your report for seven years from the date it was first reported as late. Its impact on your score decreases over time, so a late payment from six years ago hurts less than one from six months ago, but it still counts.
Will checking my own credit score lower it?
No. Checking your own credit report or score is a soft inquiry and does not affect your number. You can check your score as often as you want without any impact.
Is it better to have a zero balance on my credit cards?
No. A small balance that you pay off each month is better than zero. A zero balance shows no recent activity, while a small balance demonstrates you use the card responsibly and pay on time.
How much does opening a new credit card lower my score?
Opening a new card typically lowers your score by 5 to 10 points due to the hard inquiry and the new account. The impact is temporary and fades within a few months as the account ages and you build a payment history on it.
