What Hurts Your Credit Score the Most?

One late payment or a maxed-out card, which one really hurts your credit score more? Both can sting, but a missed payment usually does the deepest damage. Your score is built from a few weighted factors, and the two heaviest, payment history and how much you owe, are also the two that hurt the most when they go wrong. This guide ranks the negative factors by impact, using the common FICO factor weights, so you know what to protect first.

The FICO Factor Weights

Most FICO scores are built from five factors, each carrying a different weight. The bigger the weight, the more that factor can help or hurt your score.

Here is how the common FICO model splits them up.

VantageScore uses similar ideas with different labels and weights, so your two scores can differ. Still, on almost every model, your payment behavior and how much you owe matter most.

These weights are also a to-do list in disguise. If you want the biggest gains, work from the top down: protect your payment history first, then your utilization. The bottom three factors move your score much less, so they deserve less of your worry.

#1 Missed and Late Payments

Payment history is worth about 35% of your FICO score, more than any other factor. That is why missed and late payments are the number one thing that hurts your score.

Most lenders report a payment as late once it is 30 days past due. A single 30-day late payment can drop a strong score sharply, and the higher your score, the further it can fall.

The damage depends on how late and how recent the payment is. A payment 90 days past due hurts more than one that was 30 days late. A miss from last month also weighs more than one from three years ago.

What tends to do the most damage in this category:

• Payments reported 30, 60, or 90+ days late
• Skipped payments that slide into default
• Bills sent to collections after missed payments

A late payment can stay on your credit report for up to 7 years. Its sting fades over time, but the record remains. The best defense is prevention. For a plan to rebuild, see our guide on how to improve your credit score fast.

#2 High Credit Utilization

The amounts you owe make up about 30% of your score, and most of that comes from credit utilization. Utilization is simply how much of your available credit you are using.

Maxing out a card, or carrying high balances across several cards, is the second biggest thing that hurts your score. The good news is that this factor updates quickly.

Pay your balances down and your score can bounce back within a billing cycle or two.

We keep the math in its own guide. To see exactly how the ratio is calculated and what target to aim for, read how credit utilization affects your score. To plan the payoff itself, our Credit Card Payoff Date Calculator shows how fast a steady payment clears a balance.

Serious Damage: Collections, Defaults, and Bankruptcy

Some events go far beyond a single late payment. These major derogatory marks cause deep damage and last for years. They can also make new credit harder to get and more expensive when you do qualify.

Here is roughly how long the most serious marks can stay on your credit report:

• Collections: an unpaid debt handed to a collection agency can stay about 7 years.
• Charge-offs and defaults: when a lender writes off a debt as a loss, it can stay about 7 years.
• Bankruptcy: most bankruptcies stay 7 to 10 years, depending on the type filed.

Paying off a collection is still worth doing, and some newer scoring models ignore paid collections. Even so, the record can remain on your report for years, so prevention beats cleanup every time.

These marks hurt most when they are fresh and ease as they age. But because they last so long, avoiding them matters more than almost anything else you can do for your score.

Smaller Hits: Hard Inquiries and Closing Accounts

Not every negative is a disaster. Some factors cause only small, short-lived dips.

A hard inquiry happens when a lender checks your credit for a new application. Each one is a minor hit that usually affects your score for about a year, while staying on your report for about 2 years. A soft inquiry, like checking your own score, does not hurt at all.

Rate shopping is treated kindly. When you apply for one loan, like a mortgage or an auto loan, many inquiries made in a short window are usually counted as a single inquiry. So comparing lenders will not stack up hit after hit.

To learn which checks count against you, see hard vs soft credit inquiries.

Closing an account can also nudge your score down. It can lower your total available credit, which raises your utilization, and over time it can shorten your average account age. Keeping old, paid-off cards open, with an occasional small purchase, is often the safer move.
