What Actually Hurts a Credit Score, Ranked by Impact

What hurts your credit score most is anything that tells a lender you didn’t pay as agreed: bankruptcy, foreclosure, collections and charge-offs, and late payments of 30 days or more. Next comes using a big share of your available credit. Things people worry about most, like hard inquiries and opening a new card, sit near the bottom. They’re real, but small and short-lived.

That order isn’t a guess. FICO publishes the general weights behind its scores: payment history is about 35%, amounts owed about 30%, length of credit history 15%, new credit 10% and credit mix 10%. The ranking below follows those weights, plus how severe and how long-lasting each kind of damage is.

One thing before the list. Exact point drops vary a lot from person to person, and anyone who promises you “a late payment costs 100 points” is oversimplifying. FICO’s own research on how credit actions impact FICO scores makes this point directly: the same event hits different profiles very differently. We’ll come back to why.

What hurts your credit score most, ranked

1. Bankruptcy

The single most damaging item a credit file can carry. It tells every future lender that at least some debts weren’t repaid at all. The FCRA lets a bankruptcy be reported for up to 10 years under 15 U.S.C. § 1681c. In practice the bureaus remove a completed Chapter 13 after seven years, while Chapter 7 stays the full ten.

2. Foreclosure, short sale or repossession

Losing a house or a car to the lender is close behind. These usually come bundled with a string of serious late payments leading up to them, so the score takes several hits at once. They can stay for seven years.

3. Charge-offs and collections

When a lender gives up on collecting and writes the debt off, or sells it to a collection agency, that’s a major negative mark. Collections from unpaid utilities, phone bills and old rent hurt just like a credit card that went to collections. Both can remain for seven years from the date of the original delinquency.

4. Payments 90 days or more late

A 90-day late is far worse than a 30-day late. It signals a real inability to pay, not a forgotten due date. In FICO’s own simulations, a 90-day delinquency cost more points than a 30-day one for every sample profile shown.

5. A 30- or 60-day late payment

This is the one that surprises people. A single 30-day late on an otherwise perfect file can cost a lot, precisely because the file was perfect. Payment history is the biggest single category, and that first blemish changes the picture. The good news: it fades. A two-year-old 30-day late matters much less than last month’s.

A tip that’s saved plenty of people: lenders generally don’t report a payment as late until it’s 30 days past due. If you missed a due date by a week, pay it now. You’ll probably owe a late fee, but your credit file likely won’t show anything.

6. Running your cards near their limits

Credit utilization (your card balances divided by your card limits) is the heart of the “amounts owed” category. Max out a card or two and your score can drop quickly. Both your overall utilization and the usage on individual cards count.

The difference from everything above it: utilization has no memory in most scoring models. Pay the balances down and the score recovers as soon as the new, lower balances are reported, often within a month or two. In the same FICO simulations, cutting revolving balances by 25% raised the score for each sample profile. Our guide to credit utilization explains why the “30% rule” is more of a rough guide than a rule.

7. Closing old credit cards

Closing a card doesn’t erase its history right away. A closed account in good standing can stay on your report for up to ten years. What does change instantly is your available credit. Close a $10,000-limit card while carrying $3,000 on another card with a $5,000 limit, and your utilization jumps from 20% to 60%. That’s the real damage.

8. Opening several new accounts in a short window

New accounts lower the average age of your accounts and suggest you might be stretching. One new card a year barely registers. Four in three months is a different story, especially on a short or thin credit file, where each new account is a bigger share of everything the model can see.

9. Hard inquiries

When you apply for credit and a lender pulls your report, it records a hard inquiry. According to myFICO, one additional inquiry takes less than five points off most people’s FICO scores. Inquiries stay on the report for two years but only affect FICO scores for one. Rate shopping for a mortgage, auto or student loan is protected: multiple inquiries for the same kind of loan within a short window count as one. Our soft pull vs. hard pull guide covers which checks count and which don’t.

10. Letting every account go quiet

This one’s sneaky. To produce a FICO score, the file needs at least one account that’s been reported in the last six months. If you stop using all your cards, an issuer may close one for inactivity, which feeds right back into problem number 7. Use each card for something small every few months and pay it off.

Why the same mistake costs some people more

If two people both miss a payment, the one with the higher score usually loses more points. That sounds unfair until you think about what a score is: a prediction. A late payment on a file full of late payments adds little new information. A late payment on a spotless file is news, and the score reacts to news.

The same logic explains why people with short histories feel every move. With only two or three accounts, one change is a big share of the file.

It’s also why “my score dropped 40 points” can be true for your friend and “mine only dropped 15” can be true for you, after the same event. Neither of you is wrong.

How long each kind of damage lasts

The CFPB’s page on how long negative information stays on a credit report covers the same ground from the consumer’s side. Remember that “on the report” and “hurting the score” aren’t the same thing. Older negatives weigh less every year.

Things that don’t hurt your credit score

Plenty of what people fear has no effect at all:

• Checking your own score or report. Always a soft inquiry.
• Soft-pull checks by others, such as pre-qualification, account reviews, and lookups like ours. They’re invisible to lenders.
• Your income, job, age or marital status. FICO doesn’t use any of them to calculate your score, even though a report may list an employer or your date of birth.
• Debit card spending, since it isn’t credit.
• Medical bills in many cases. Since changes made in 2022 and 2023, the three bureaus leave paid medical collections and medical collections under $500 off credit reports, and they wait a year before an unpaid medical debt can appear. A broader CFPB rule to remove medical debt from reports was finalized in January 2025, but a federal court vacated it in July 2025, so those bureau policies are the protections in place today.
• Paying off a car loan. Your score might dip slightly because you have one less active installment account, but it’s minor and temporary. Don’t keep a loan open just to protect your score.

FICO Score 4 plays by older rules

Most free apps show a newer model. The score mortgage lenders pull from TransUnion, FICO® Score 4, is an older one, and it treats a few things differently. A paid collection still counts against you on FICO Score 4, where newer models like FICO Score 9 ignore it. Medical collections are treated like any other collection. And older FICO versions use a 14-day window for rate-shopping inquiries instead of the 45-day window on newer ones.

That matters if you’re about to buy a house. Pay off collections anyway, because lenders read the report and not just the score, but don’t expect FICO 4 to jump the way a free app might. Our explainer on FICO Score 4 and our page on why we use FICO Score 4 go deeper.

Getting back on track

The fixes line up with the ranking. Get every account current first, since nothing else matters much while you’re still missing payments. Then pay down card balances, which is the fastest way to recover points. Leave old cards open. Space out new applications. And check your reports for errors at AnnualCreditReport.com, since a collection that isn’t yours belongs in the dispute pile, not the “what hurts” pile.

If you’re trying to understand where someone stands before you lend, rent or co-sign, the factors behind the score tell you more than the number. Our lookup shows the key factors holding a FICO Score 4 back, alongside on-time payment record, utilization and total debt. And if you want to learn to read those yourself, start with credit report vs. credit score and what a good credit score is, then who checked my credit for the inquiry side.
