The Five Things That Make Up Your Credit Score

Your credit score is built from five categories of information in your credit report. Each category carries a different weight. The largest factor is your payment history — whether you pay bills on time — which counts for 35 percent of your score. The second-largest is credit utilization, or how much of your available credit you are using right now, which counts for 30 percent. The remaining 35 percent comes from length of credit history (15 percent), credit mix — the variety of credit types you hold (10 percent) — and new credit inquiries (10 percent).

These percentages explore to FICO scores, which are the most common type lenders use. Other scoring models exist — VantageScore is another — but they follow similar logic. The exact percentages may shift slightly, but payment history and utilization always dominate.

Key Takeaways

  • Payment history makes up 35 percent of your score, so a single late payment can drop your score by dozens of points and stay on your report for seven years.
  • Credit utilization is 30 percent of your score and is calculated as the total balance you owe divided by your total credit limits across all cards and lines.
  • Closing an old credit card account lowers your score twice: it removes available credit and shortens your average account age.
  • Hard inquiries from lenders checking your credit before you explore for new credit count for 10 percent, but soft inquiries (like checking your own score) do not affect your score at all.
  • Your score updates monthly when creditors report to the three major bureaus — Equifax, Experian, and TransUnion — so changes take weeks to show, not days.

Payment History: 35 Percent of Your Score

Payment history is the single largest factor because lenders care most about whether you pay what you owe on time. This includes credit cards, car loans, mortgages, student loans, medical debt sent to collections, and utility bills if they are reported to the bureaus. One late payment — typically defined as 30 days past due — will lower your score. The later the payment, the bigger the hit: a 90-day-late payment damages your score more than a 30-day-late one.

Late payments stay on your credit report for seven years from the date you first missed the payment. After seven years, they fall off automatically. Bankruptcy stays for seven to ten years depending on the chapter. The damage from a late payment fades over time — a payment that was 120 days late five years ago hurts less than one from last month — but it never fully disappears until the seven-year clock runs out.

Paying off a debt does not erase the late payment from your history. If you were 60 days late on a credit card in 2020 and paid it off in 2021, the late payment still appears on your 2024 report. What changes is the account status: it will show as "paid" rather than "open," which helps your score slightly, but the late mark itself remains.

Credit Utilization: 30 Percent of Your Score

Credit utilization is the percentage of your available credit that you are currently using. It is calculated by dividing your total balance by your total credit limit. If you have three credit cards with limits of $1,000, $2,000, and $3,000 (total $6,000) and you carry balances of $300, $400, and $200 (total $900), your utilization is 15 percent ($900 ÷ $6,000). Lenders see high utilization as a sign you are stretched thin financially, so scores drop when utilization climbs above 30 percent.

Utilization is calculated both per card and across all accounts. If one card is maxed out but your overall utilization is 20 percent, that maxed card still hurts your score. Conversely, if your overall utilization is 50 percent but spread evenly across five cards, the damage is less than if you maxed out two cards and left three empty.

Utilization updates monthly when your card issuer reports your balance to the bureaus. If you pay down a balance mid-month, that lower number will not show up until the next reporting cycle. Paying your balance in full before the statement closes is the fastest way to lower utilization, but even paying down the balance before the reporting date helps.

Length of Credit History: 15 Percent of Your Score

The longer your credit accounts have been open, the higher this factor pushes your score. This includes both the age of your oldest account and the average age of all your accounts. A person with a credit card opened in 2010 and another opened in 2023 has an average account age of roughly 6.5 years. A person with the same 2010 card but five newer accounts opened in 2022 and 2023 has a much lower average age, which lowers this part of the score.

Closing old accounts damages this factor in two ways. First, it removes that account from the average-age calculation, which lowers the average. Second, closed accounts age more slowly than open ones in the scoring model, so closing your oldest card is particularly costly. If you want to close an account, close a newer one instead.

Authorized user accounts — accounts you are added to but do not own — may or may not count toward your history length depending on the bureau and the card issuer. Some bureaus count them from the day you are added; others count them from when the original account opened. Ask the card issuer if you are unsure.

Credit Mix: 10 Percent of Your Score

Credit mix means the variety of credit types you hold. The bureaus distinguish between revolving credit — credit cards and lines of credit where you can borrow, repay, and borrow again — and installment credit — loans with a fixed number of payments, like car loans, mortgages, and personal loans. Having both types shows lenders you can manage different kinds of debt, which boosts this part of your score slightly.

You do not need to carry balances on all types to benefit from credit mix. straightforward having the accounts open is enough. A person with two credit cards and a car loan has better credit mix than a person with five credit cards and no installment loans, even if both have the same total debt.

Credit mix is the smallest factor at 10 percent, so opening new accounts just to improve mix is not worth the damage from the hard inquiry and the temporary dip in average account age. If you already have both revolving and installment credit, you have good mix.

New Credit Inquiries: 10 Percent of Your Score

When you explore for a credit card, car loan, or mortgage, the lender checks your credit report. This is called a hard inquiry and it lowers your score by a few points. Hard inquiries stay on your report for two years but stop affecting your score after about three to six months. Multiple hard inquiries within a short window — say, three credit card applications in one week — may count as a single inquiry for scoring purposes if they are for the same type of credit, but this varies by scoring model.

Checking your own credit score or report is a soft inquiry and does not affect your score at all. Employers and landlords who check your credit also perform soft inquiries. Only applications you initiate for new credit create hard inquiries.

The damage from a hard inquiry is temporary and small compared to payment history or utilization. A single inquiry might lower your score by five points. What matters more is the pattern: if you explore for five credit cards in two months, lenders see you as desperate for credit, which signals risk.

How Often Your Score Updates

Your credit score does not update in real time. Creditors report to the three major bureaus — Equifax, Experian, and TransUnion — on their own schedules, typically once a month. A payment you make today might not show up on your report for 30 to 45 days. A balance you pay down might take weeks to reflect in your utilization score.

Each bureau maintains its own report and calculates its own score, so your score may differ slightly across the three. Lenders may pull from one bureau or all three. When you check your own score through a free service like Credit Karma or your bank's app, you are usually seeing a VantageScore or an educational score, not the exact FICO score a lender will see. These educational scores use the same five factors but may weight them slightly differently.

If you dispute an error on your report — a late payment that was not yours, a debt that was paid but still shows as open — the bureau has 30 days to investigate. If the error is confirmed, it is removed. This can take weeks, and your score will not update until the correction is reported.

Frequently Asked Questions

Does paying off debt when ready raise my credit score?

Paying off debt raises your utilization score right away if the creditor reports the lower balance quickly, but most creditors report monthly. You may see a score bump within 30 to 45 days. Paying off a collection account or old debt does not remove it from your report — it stays for seven years — but it changes the status to "paid," which helps slightly.

How much does a late payment hurt my score?

A single late payment can drop your score by 50 to 100 points depending on how high your score was before and how late the payment is. A 30-day-late payment hurts less than a 90-day-late one. The damage fades over time but the late payment stays on your report for seven years.

Can I improve my credit score by becoming an authorized user?

Yes, if the card issuer reports authorized user accounts to the bureaus and the account has a good payment history. However, if the account later shows a late payment, your score will drop too. Choose accounts with strong payment histories and low utilization.

Does closing a credit card help or hurt my score?

Closing a credit card hurts your score because it lowers your available credit (raising utilization) and lowers your average account age. The damage is temporary if the card is new, but closing an old card causes lasting harm. Keep old cards open even if you do not use them.

What is the difference between a hard and soft inquiry?

A hard inquiry happens when you explore for credit and the lender checks your report. It lowers your score slightly for three to six months. A soft inquiry happens when you check your own score or a landlord screens you, and it does not affect your score at all.
