What Actually Changes Your Credit Score

Your credit score moves based on five specific things: how much debt you owe compared to your credit limits, whether you pay on time, how long you have held credit accounts, the mix of different types of credit you use, and how often you explore for new credit. Credit bureaus—Equifax, Experian, and TransUnion—track these factors and sell scores to lenders. The most widely used score is the FICO score, which ranges from 300 to 850. The higher your score, the lower the interest rate lenders will offer you.

Each factor carries a different weight. Payment history is the heaviest—it makes up 35 percent of your score. The amount you owe relative to your limits comes next at 30 percent. The remaining 35 percent is split among how long your accounts have been open, the types of credit you carry, and how recently you have sought new credit. Understanding what moves the needle on each one helps you make decisions that protect your score rather than harm it.

Key Takeaways

  • Payment history is the single largest factor in your credit score, so a late payment can drop your score by 100 points or more depending on how late it was.
  • Credit utilization—the percentage of your available credit you are using—should stay below 30 percent to avoid signaling financial strain to lenders.
  • Closing old credit accounts can lower your score even if you pay them off, because it reduces the length of your credit history and the total credit available to you.
  • Hard inquiries from lenders checking your credit when you explore for a loan or card will temporarily lower your score, but soft inquiries from employers or yourself do not.
  • A mix of credit types—cards, installment loans, mortgages—helps your score more than having only one type, though payment history matters far more than the mix itself.

Payment History: 35 Percent of Your Score

A single late payment can drop your score by 100 points or more, depending on how late it is and what your score was before. A payment 30 days late does less damage than one 90 days late. A payment that goes to collections or results in a charge-off—when a lender writes off the debt as uncollectible—causes the steepest drop. The damage fades over time: a late payment from seven years ago hurts less than one from last month, and after seven years most negative marks fall off your report entirely.

Payment history includes not just credit cards but also car loans, mortgages, student loans, medical bills sent to collections, and utility payments if they are reported to the bureaus. Missing a payment by even one day can be reported as late. Some lenders offer a grace period of a few days, but the safest approach is to pay by the due date shown on your statement. If you are struggling to make a payment, contact the lender before the due date—many will work with you on a new payment plan rather than report you late.

Paying off a debt does not erase the late payment from your history. The mark stays on your report for seven years from the date you first missed the payment, though its impact weakens each year. Paying the debt does stop additional late marks from accumulating and prevents the account from going to collections or being charged off.

Credit Utilization: How Much of Your Limit You Use

Credit utilization is the total amount of debt you owe divided by your total available credit across all cards and lines of credit. If you have three credit cards with $5,000 limits each and you carry $4,500 in total debt across them, your utilization is 30 percent. Keeping utilization below 30 percent signals to lenders that you are not financially stretched. Utilization above 50 percent typically begins to damage your score noticeably.

Utilization is calculated across all your accounts combined, not per card. If one card is maxed out but your others are empty, your overall utilization may still be low—but that maxed card itself signals risk. The bureaus also look at per-card utilization, so spreading debt across multiple cards helps more than concentrating it on one. Paying down balances is the fastest way to improve this factor; unlike payment history, utilization changes month to month as you pay down or charge up.

Requesting a credit limit increase without a hard inquiry can lower your utilization when ready without changing how much you owe. Many card issuers allow you to request a limit increase online, and some do a soft pull of your credit that does not affect your score. Closing a credit card after paying it off can actually hurt your score by reducing your total available credit and raising your utilization percentage, even though the card itself now carries a zero balance.

Length of Credit History: 15 Percent of Your Score

The longer your oldest account has been open, the better for your score. An account that has been open for 10 years helps more than one that has been open for 2 years. The bureaus track both the age of your oldest account and the average age of all your accounts. Closing old accounts lowers the average age and removes that account from the calculation, which can drop your score even if the account was in good standing.

This is why financial advisors often recommend keeping old credit cards open even after you pay them off. The card continues to age in your favor as long as it remains open. If you want to stop using a card, you can freeze it or put it in a drawer rather than closing it. The issuer may close it for inactivity after a year or two, but that closure is initiated by them, not you, and has less impact than a closure you request.

If you are new to credit, there is no shortcut to building a long history. The only way to improve this factor is to keep accounts open and in good standing over time. Young people with short credit histories often have lower scores not because they have made mistakes, but straightforward because they have not had credit long enough. This factor matters less than payment history or utilization, so focusing on those two first is the better strategy.

Credit Mix: Types of Credit You Carry

Credit comes in two main types: revolving credit (credit cards and lines of credit that you can borrow from repeatedly) and installment credit (loans with a fixed payment and term, like car loans, mortgages, and personal loans). Having both types on your report is better for your score than having only one. A person with three credit cards and no loans will have a lower score than someone with three cards and a car loan, all else equal.

Credit mix makes up only 10 percent of your score, so it should not drive your decisions. Opening a new loan just to improve your mix is not worth the temporary score drop from the hard inquiry and the risk of taking on debt you do not need. If you already have multiple types of credit, your mix is probably fine. If you have only credit cards, a car loan or mortgage will naturally add mix over time without any extra effort on your part.

Retail cards (store-branded credit cards) count as revolving credit just like regular cards, so opening a store card does not add a new type of credit to your mix. Student loans, medical debt in collections, and utility bills also factor into the mix calculation, so your credit profile is more diverse than you might think even if you only have cards and one car loan.

Hard Inquiries and New Credit: 10 Percent of Your Score

A hard inquiry happens when a lender checks your credit because you have applied for a loan, credit card, or other credit product. Each hard inquiry can drop your score by a few points, and multiple inquiries in a short time can add up. Hard inquiries stay on your report for two years but stop affecting your score after about three to six months. Soft inquiries—when you check your own credit, an employer checks it, or a lender checks it to pre-may have access to you—do not affect your score at all.

New credit accounts also affect your score. Opening a new card or loan lowers your average account age and creates a hard inquiry, both of which dip your score temporarily. The impact is usually small if your overall credit history is long and your payment history is clean. The score recovers as the new account ages and you make on-time payments on it.

If you are shopping for a mortgage or car loan, multiple inquiries within a 14-to-45-day window (depending on the scoring model) typically count as a single inquiry rather than multiple ones. This is because the credit bureaus understand that you are rate shopping, not opening multiple new accounts. Credit card inquiries do not receive the same courtesy, so spacing out credit card applications is wise if you want to minimize the score impact.

How Negative Marks Fade Over Time

Late payments, charge-offs, and collections accounts do not disappear from your report when ready, but their impact weakens as they age. A late payment from two years ago hurts your score less than one from two months ago. After seven years, most negative marks fall off your report entirely and stop affecting your score. Bankruptcy stays on your report for seven to ten years depending on the chapter.

The older a negative mark is, the less weight it carries in the score calculation. This means that even if you cannot remove a mark before seven years, your score will gradually improve as time passes and you build new positive history. Paying off a collection account does not remove it from your report, but it does stop additional damage and shows lenders that you eventually paid what you owed.

You can dispute inaccurate information on your credit report directly with the bureaus at no cost. If a late payment, collection, or other mark is reported in error, you have the right to request that it be investigated and corrected or removed. Disputing accurate information will not remove it, but disputing false information is one of the few ways to speed up the recovery process.

Frequently Asked Questions

Does paying off debt when ready improve my credit score?

Paying off debt improves your credit utilization, which can raise your score within a month or two. However, paying off a late payment does not erase the late mark from your history—it stays for seven years but stops getting worse. Paying off collections or charge-offs also does not remove the mark, but it does prevent further damage and shows future lenders that you eventually settled the debt.

How much does a hard inquiry hurt my credit score?

A single hard inquiry typically drops your score by a few points, and the impact fades after three to six months. Multiple inquiries in a short time add up, but inquiries for the same type of credit (mortgage, auto loan) within 14 to 45 days usually count as one. Soft inquiries from employers, landlords, or yourself do not affect your score at all.

Will closing a credit card help or hurt my score?

Closing a credit card usually hurts your score because it reduces your total available credit and lowers the average age of your accounts. Even if the card has a zero balance, closing it raises your credit utilization percentage on your remaining cards. Keeping old cards open and unused is better for your score than closing them.

Can I remove a late payment from my credit report?

You cannot remove an accurate late payment before seven years have passed. However, you can dispute it if it is reported incorrectly, and you can ask the creditor to remove it as a goodwill gesture if it was an isolated incident and you have since made on-time payments. Some creditors will agree, but they are not required to. After seven years, the mark falls off automatically.

What credit score do I need to get approved for a loan?

Different lenders have different minimums. Most mortgages require a score of at least 620, though better rates start around 740. Auto loans often go lower, around 600. Credit cards vary widely; some accept scores in the 600s while others require 700 or higher. The higher your score, the lower the interest rate you will be offered, so improving your score saves you money even if you already may have access to.
