7 Common Actions that Can Hurt Your Credit Score

Knowing – and avoiding – financial moves that can make your credit score go down is key to helping you build excellent credit and maintaining it over time.


The higher your credit score, the harder it’ll be hit if certain financial slipups occur.

The two actions that can trigger a major fall in credit score are missing a payment by more than 30 days and using all of your available credit.

Some financial moves can ding your credit score in the short term but boost it over time.

Building a solid credit score can potentially help you improve your personal finances over the years, from helping you qualify for lower interest rates on loans and mortgages to increasing your chances of qualifying for more rewarding credit cards. But once your credit score is rated Excellent or Good, it’s time to play defense to avoid common money missteps that can lower your credit score – especially because the higher your credit score, the more points a mistake can cost you.

Why Credit Mishaps Can Hurt a High Credit Score More than a Low Credit Score 

Credit scores are all about giving lenders and businesses a read on your track record in making smart spending and borrowing choices. For example, a low credit score signifies a high risk, so financial mistakes confirm what is already known. But if you have a high credit score and make a habit out of late payments, it’s considered bigger news because it’s out of character and may signal trouble ahead.1


An example from FICO, the credit scoring system most often used by businesses, estimates that someone with a great credit score could see a drop of 60 to 80 points if they were 30 days late with one payment. Someone with a less-than-great score might see their score drop 25 to 45 points for the same slipup.2  


Another popular scoring system, VantageScore, has its own algorithm for determining the size of a point cut for a given infraction. The free Credit Score Simulator at MyCreditGuide pulls up your personal VantageScore data so you can see how certain money moves – making late payments, opening a new personal loan, canceling a credit card – might impact your credit score.

Alas, there are more than a few actions that can make your credit score go down.

1. Making a Payment More than 30 Days Late

If you are just a few days late, your credit score probably won’t decrease. It’s when you fall more than 30 days behind that your score will take a dip. The faster you get back on schedule, the better. The point drop for being 90 days behind on a payment is more severe than the decline you would see for being 30 days late. It’s best to avoid late payments altogether, as your payment record is the single most important variable in computing your FICO credit score, accounting for 35% of your score.

2. Using More than 30% of Your Available Credit Card Limits

Another variable all scoring models care about is your credit utilization ratio, which makes up 30% of your FICO credit score. To find your credit utilization ratio, add up the maximum credit limits on all your credit cards and compare that to your outstanding balances on those cards. Folks with excellent credit scores typically have a credit utilization rate below 30%. 

3. Canceling a Credit Card

Your average credit account history determines 15% of your FICO score. Cancel a card with a very long history and your average credit history will decrease, which could pull down your credit score. But that’s not all. Canceling a card will also increase your credit utilization ratio because you’ll decrease your total available credit limit. 

4. Changing Your Credit Limit

If your credit card issuer reduces your credit limit – this sometimes can happen during economic downturns when unemployment rises – your credit utilization will rise, which, you guessed it, can impact your credit score. Increasing your credit limit without running up bigger balances, on the other hand, won’t have much impact. However, some card issuers will run a hard credit check before raising your credit limit, which will typically cause a small, temporary dip in your FICO credit score.3

5. Taking Out a New Loan or Adding Another Credit Card

This one is tricky. In the short term, you may see your credit score drop a bit when you open a new credit account. It can happen for a few reasons:

  • Every time you apply for a new credit card or loan, creditors will make a hard inquiry.
  • If you have yet to establish a long credit history, a new card will cause that average to fall a bit, which can shave some points off your score.
  • Adding the new debt of a personal loan can cause your credit score to dip.

However, a hard inquiry affects your score only temporarily. And in the long term, if you continually make on-time payments, you can typically expect to see your credit score start climbing within a year. Finally, if the personal loan is manageable and you can pay it off over a reasonable period of time, increasing your mix of credit types can actually boost your credit score.

6. Experiencing a Major Financial Setback

Defaulted loans, accounts in collections, bankruptcy, home foreclosures, and repossessed cars can all lead to “derogatory” marks on your credit report, none of which will help your score. That said, the events that typically lead to those unfortunate outcomes – such as missed payments or maxed-out credit cards – likely will have already caused a major drop in your credit score. 


Most of these setbacks will stay on your credit report for up to seven years or more, even if you pay off the account. The good news is, that impact on your credit score will decrease with time as long as you take the steps to rebuild your credit score.

7. Paying Off a Loan in Full

It seems counterintuitive, but here’s the deal: 10% of your FICO credit score is based on your mix of credit cards and loan types. When you finally pay off a loan, it decreases your credit mix, which can in turn ding your credit score. But that shouldn’t be a reason to avoid paying off loans. Common financial wisdom says it’s better to eliminate debt than fret over a small, temporary dip in your credit score. For more on eliminating debt, read “What is Debt Free Living?

Credit Score Damage Doesn’t Have to be Permanent

Remember that anytime your credit score falls, it’s not permanent damage. If you’ve already built up good credit, you likely know the financial habits that will help improve your credit score. So if a financial mistake happens, rest easy. There may not be a magic formula for how long it will take to get your score back to where it was, but with each month that passes, the impact of a credit blunder on your credit score will recede – as long as you manage your credit responsibly.

The Takeaway

Maintaining a solid credit score requires avoiding key money mistakes that can make a mess of things. Top financial mishaps to shun: missing payments and running up bills that max out your credit limits.
