What counts toward your credit score and what doesn't

Your credit score is built from five categories of information, and they don't all carry the same weight. Payment history — whether you pay on time — accounts for 35% of your score. Credit utilization — how much of your available credit you're using — accounts for 30%. Length of credit history accounts for 15%. Credit mix — the variety of credit types you hold — accounts for 10%. New credit inquiries account for the remaining 10%.

Not all debt shows up on your credit report at all. Utility bills, phone bills, rent, and medical debt typically don't appear unless you fall behind and the company sends the account to a collection agency. Student loans, mortgages, car loans, credit cards, and lines of credit all report to the three major credit bureaus — Equifax, Experian, and TransUnion — whether you're current or late.

This means you can have excellent payment history on rent and utilities but still have a low credit score if you carry high balances on credit cards or have missed payments on a car loan. The types of credit you use matter because lenders want to see you can handle different kinds of borrowing.

Key Takeaways

  • Payment history is the single largest factor in your credit score at 35%, and it applies to every type of credit that reports to bureaus.
  • Revolving credit like credit cards and lines of credit affects your utilization ratio, while installment credit like car loans and mortgages does not.
  • Having a mix of both revolving and installment credit can improve your score more than having only one type, even if your payment history is identical.
  • Rent and utility payments typically don't help your credit score unless you report them yourself or fall behind and enter collections.
  • Opening new accounts in a short period lowers your score temporarily because each inquiry counts against you, but the impact fades over time.

How revolving credit works and affects your score

Revolving credit is credit you can use, pay back, and use again — like a credit card or line of credit. The balance you carry on these accounts directly affects your credit score through the utilization ratio. If you have a $5,000 credit limit and carry a $2,500 balance, your utilization is 50%. Most scoring models penalize utilization above 30%, and the penalty gets steeper as you approach your limit.

Paying down revolving credit is one of the fastest ways to improve your score because utilization is recalculated every month. If you pay your balance from 50% to 10% this month, your score can jump within 30 days — the next time the card issuer reports to the bureaus. This is different from installment credit, where the balance naturally decreases on a fixed schedule.

Having multiple credit cards or lines of credit can help your score even if you don't use them, because the total available credit increases. A card with a $0 balance still counts toward your total limit. However, opening many new cards in a short period will temporarily lower your score because each application generates a hard inquiry, which counts against the "new credit" category.

How installment credit works and affects your score

Installment credit is credit you borrow in one lump sum and pay back in fixed monthly payments — like a car loan, mortgage, or personal loan. These accounts don't have a utilization ratio the way revolving credit does. Borrowing $20,000 for a car and paying it down to $15,000 doesn't hurt your score the way carrying a $15,000 balance on a credit card would.

What matters with installment credit is whether you make payments on time and whether you complete the loan as agreed. A single missed payment on a car loan or mortgage can drop your score 100 points or more, depending on how late the payment is. A payment 30 days late is less damaging than one 90 days late, but both show up on your report for seven years.

Installment accounts also build your credit mix, which is worth 10% of your score. If you have only credit cards, adding a car loan or mortgage signals to lenders that you can handle different types of debt. This mix can improve your score even if the total amount you owe stays the same.

Why credit mix matters and how to build it

Lenders use your credit score to predict whether you'll repay them. Someone who has only credit cards might have a 750 score, but a lender offering a mortgage wants to see that you've successfully managed installment debt before. Credit mix accounts for 10% of your score, which is smaller than payment history or utilization, but it's still meaningful.

You don't need to take on debt you don't need just to build mix. If you have a credit card and a car loan, you already have both revolving and installment credit. Adding a second credit card or a personal loan won't improve your mix further — it will only help if you're missing one type entirely. If you have only installment credit (like a mortgage and car loan but no credit cards), opening one credit card can modestly improve your score over time.

The timing matters. Opening multiple new accounts in a few months will temporarily lower your score because of the hard inquiries and the "new credit" category. But the impact fades. After six months, the inquiry stops counting as heavily. After two years, it barely counts at all. The account itself continues to help your mix indefinitely.

How payment history affects different credit types differently

A missed payment is a missed payment — it counts the same whether it's on a credit card, car loan, or mortgage. But the consequences can feel different because the stakes are different. Missing a credit card payment might trigger a late fee and a rate increase. Missing a car loan payment can lead to repossession. Missing a mortgage payment can lead to foreclosure.

From a credit score perspective, all late payments are reported to the bureaus and stay on your report for seven years. A payment that's 30 days late is less damaging than one that's 90 days late, but both hurt. A payment that's 120 days late or goes to collections is far more damaging — it can drop your score 130 points or more.

The good news is that the impact of a late payment fades over time. A late payment from two years ago hurts your score less than a late payment from two months ago. If you've been on time since then, the trend matters. Lenders see recent payment history as more predictive than old history, so rebuilding after a missed payment is possible.

Secured credit and how it affects your score

Secured credit is credit backed by collateral — usually a deposit you put down. A secured credit card requires a cash deposit (often $500 to $2,500) that serves as your credit limit. A car loan is secured by the car itself. A mortgage is secured by the house. From a credit score perspective, secured and unsecured credit count the same way — what matters is whether you pay on time.

Secured credit cards are often used to build or rebuild credit because they're easier to get approved for if you have no credit history or a damaged one. The deposit protects the card issuer if you don't pay. Once you've shown a year or more of on-time payments, you can often convert the card to an unsecured card and get your deposit back.

The score impact is identical whether the credit is secured or unsecured. A secured card that you pay on time every month will improve your score just as much as an unsecured card. The only difference is the approval process — secured cards are more accessible to people with limited or poor credit history.

Student loans and how they're treated differently

Student loans report to the credit bureaus like any other installment credit, but they're treated as a special category by some lenders. Federal student loans have protections that other debts don't — you can defer payments, enter income-driven repayment plans, or pursue forgiveness programs without it counting as a default on your credit report (though interest may still accrue).

From a credit score perspective, student loans help your credit mix because they're installment credit. Making on-time payments builds your payment history. Carrying a large student loan balance doesn't hurt your utilization ratio the way credit card debt does, because student loans aren't revolving credit. However, if you default on a federal student loan — typically after 270 days of non-payment — it will severely damage your credit score and can stay on your report for seven years.

Private student loans don't have the same protections as federal loans. Missing a payment on a private student loan is treated like missing any other loan payment and will be reported to the bureaus immediately.

Frequently Asked Questions

Does paying rent build my credit score?

Rent payments typically don't report to the credit bureaus, so they don't help your score. However, some landlords and property management companies now report to bureaus through services like RentBureau or Experian Boost. If you fall behind on rent and it goes to collections, that will hurt your score. You can ask your landlord whether they report to the bureaus.

What happens to my credit score if I pay off a loan early?

Paying off an installment loan early doesn't hurt your score, but it does close the account. Once closed, the account stops actively helping your credit mix, though it stays on your report for up to seven years and continues to show your payment history. Paying off revolving credit (credit cards) early is different — it lowers your utilization ratio and can improve your score.

Does closing a credit card hurt my score?

Closing a credit card can lower your score because it reduces your total available credit, which increases your utilization ratio on remaining cards. It also removes an active account from your credit mix. The impact is usually temporary and smaller if you have other cards open. Closed accounts stay on your report for about 10 years.

Can I improve my score by opening new credit accounts?

Opening new accounts will temporarily lower your score because of the hard inquiry and the new account itself. However, over time, new accounts can help by increasing your available credit (which lowers utilization) and adding to your credit mix. The temporary dip usually fades within a few months, and the long-term benefit can be worth it if you need to build credit.

How much does a missed payment hurt compared to high credit card balances?

A single missed payment is usually more damaging than high balances. A 30-day late payment might drop your score 60 to 100 points, while high utilization might drop it 20 to 50 points. However, high utilization is ongoing — it hurts your score every month until you pay it down. A missed payment hurts most immediately but its impact fades over time.
