Late payments, high credit card balances, and collections accounts are the biggest factors that hurt your credit score. Your FICO score is built from five categories, each weighted differently, and problems in any of them can drag your number down. Understanding exactly how each factor works helps you figure out what’s costing you points and what to fix first.
The Five Factors Behind Your Score
FICO scores, which lenders use in the vast majority of credit decisions, are calculated from five categories of data on your credit report: payment history (35%), amounts owed (30%), length of credit history (15%), new credit (10%), and credit mix (10%). The first two categories alone account for nearly two-thirds of your score, which is why a missed payment or a maxed-out credit card can do so much damage while something like applying for a new account barely moves the needle.
Late and Missed Payments
Payment history is the single largest factor in your score, and even one late payment can cause a significant drop. The damage depends on how late the payment is. Most creditors don’t report a payment as late until it’s 30 days past due, so missing your due date by a few days typically won’t show up on your credit report. But once a payment hits the 30-day mark, it gets reported, and the later it gets (60 days, 90 days, 120 days), the worse the impact.
A single 30-day late payment can cost someone with an otherwise strong credit history 60 to 100 points or more. People with higher scores tend to lose more points from a single negative event because there’s more distance to fall. Late payments stay on your credit report for up to seven years, though their impact fades over time. A late payment from five years ago hurts much less than one from five months ago.
If you stop paying altogether, the account will eventually be charged off, meaning the creditor writes it off as a loss. That charged-off status is one of the most damaging marks you can have. The debt may then be sold to a collections agency, adding a separate collections account to your report.
High Credit Card Balances
The “amounts owed” category is largely driven by your credit utilization rate: the percentage of your available revolving credit you’re currently using. If you have a credit card with a $10,000 limit and a $3,000 balance, your utilization on that card is 30%. Scoring models look at both your overall utilization across all cards and the utilization on each individual card.
There’s no single cutoff where utilization goes from fine to harmful, but 30% is the point where the negative effect becomes more pronounced. Keeping utilization in the single digits is ideal. One important detail: having even one card near its limit can hurt your score even if your overall utilization is low. A card sitting at 95% utilization sends a risk signal regardless of what your other cards look like.
Unlike late payments, utilization damage is temporary. Your score recalculates based on the balances reported each month, so paying down a card can produce a noticeable score improvement within one billing cycle. This makes high balances one of the fastest problems to fix.
Collections Accounts
When an unpaid debt gets sent to a collections agency, that agency typically reports the account to the credit bureaus. A collections account is a serious negative mark and can stay on your report for up to seven years from the date of the original delinquency. Even small amounts in collections, like an old utility bill or gym membership you forgot about, can drag your score down.
Medical debt in collections deserves a special mention. The three major credit bureaus voluntarily stopped reporting medical collections under $500 in recent years, and paid medical collections are no longer included on credit reports. The CFPB attempted to finalize a broader rule banning all medical debt from credit reports, but a federal court vacated that rule in July 2025, finding it exceeded the bureau’s authority. So medical collections above $500 that remain unpaid can still appear on your report and affect your score.
Too Many New Credit Applications
Each time you apply for credit and a lender checks your report, a hard inquiry is recorded. A single hard inquiry typically lowers your score by five to ten points. That’s relatively minor, but multiple hard inquiries in a short period can add up and signal to lenders that you’re desperate for credit.
There’s an important exception for rate shopping. If you’re applying for a mortgage, auto loan, or student loan at multiple lenders to compare rates, recent FICO scoring models count all inquiries of the same type within a 45-day window as a single inquiry. Older scoring versions use a 14-day window. Either way, you’re protected when comparing loan offers, so don’t let the fear of hard inquiries stop you from shopping around on a major loan.
Soft inquiries, like checking your own credit or a lender pre-approving you for an offer, don’t affect your score at all.
Closing Old Accounts
Length of credit history makes up 15% of your score. Scoring models consider the age of your oldest account, the age of your newest account, and the average age across all accounts. When you close an old credit card, it can shorten your average account age and reduce your total available credit, both of which can lower your score.
The closed account doesn’t vanish immediately. Accounts closed in good standing can remain on your report for up to ten years. But once they eventually fall off, the average age of your remaining accounts may drop noticeably, especially if that card was one of your oldest. This is why keeping a long-held credit card open, even if you rarely use it, can be worth the effort.
Bankruptcy and Public Records
Bankruptcy is the most severe credit event. A Chapter 7 bankruptcy stays on your credit report for up to ten years, while a Chapter 13 bankruptcy remains for seven years. The initial score drop can be 150 points or more depending on where you started. Information about lawsuits or judgments can also be reported for seven years or until the statute of limitations expires, whichever is longer.
Having Only One Type of Credit
Credit mix accounts for 10% of your score. Scoring models like to see that you can manage different types of credit, such as credit cards (revolving credit), an auto loan or mortgage (installment credit), and retail accounts. If you only have credit cards and no installment loans, or vice versa, your score may be slightly lower than someone with a healthy mix. That said, 10% is a small slice of your score, and you should never take on debt you don’t need just to diversify your credit profile.
How Long Negative Marks Last
Most negative information stays on your credit report for seven years. That includes late payments, collections, charge-offs, and settled accounts. Bankruptcies are the exception, lasting up to ten years for Chapter 7. Hard inquiries are shorter-lived, typically dropping off after about two years, with most of their scoring impact fading within the first year.
The recency of negative marks matters as much as their presence. A 90-day late payment from six years ago has far less influence on your score than a 30-day late payment from last month. Scoring models weight recent behavior more heavily, which means consistent on-time payments and lower balances today can gradually offset past mistakes even while those marks are still technically visible on your report.
