How Credit Card Debt Affects Your Credit Score

Credit card debt affects your credit score mainly through two factors — how much of your available credit you use and whether you pay on time. High balances and missed payments can drop your score by 50 to 100+ points, while paying down balances and making on-time payments can lift it within one to two billing cycles.

Some of the most powerful ways to pay off credit card debt require a good credit score. But to a lender, high credit card balances are a sign of someone struggling financially.

Key Takeaways

• How does credit card debt affect your credit score? Mostly through utilization and payment history: High balances and missed payments can cost you 50 to 100+ points.

• Utilization is 30% of your FICO score: Keep it under 30% of your available credit — and under 10% is even better.

• Payment history matters even more, at 35%: A payment 30+ days late gets reported and can stay on your report for up to seven years.

• Paying down balances works fast: Lower utilization can lift your score 10 to 50 points in a single billing cycle once the issuer reports it.

• A hard inquiry is a small, temporary hit: Applying for a card usually drops your score by fewer than five points and only affects it for about 12 months.

• Think twice before closing a paid-off card: It shrinks your available credit and can raise your utilization, so keeping it open is often the safer move.

How Does Credit Card Debt Affect Your Credit Score?

The big reason credit card debt affects your credit score is that it increases your credit utilization rate, a factor that makes up a whopping 30% of your overall FICO score.

Your credit utilization (also called “amounts owed”) measures the percentage of your available credit that you’re currently using. For example, let’s say you’ve got a total balance of $1,000:

• If your total credit limit is $10,000 across all your cards, you’re using 10% of your available credit — so your credit utilization is 10%.

• If your total credit limit is $50,000 across all your cards, you’re using 2% of your available credit — so your credit utilization is 2%.

Here’s how different utilization levels tend to affect your score.

High credit card utilization hurts your credit score: The higher your amounts owed, the more of a red flag you are to would-be lenders. A borrower with maxed-out credit cards looks desperate for money and is therefore seen as a riskier customer. Keeping your credit utilization below 30% is a widely cited guideline, and CFPB guidance indicates that lower utilization supports a stronger score — people with the highest scores tend to stay under 10%.

Say you carry $15,000 in credit card debt spread across four cards with a combined $20,000 limit. That puts your utilization at 75%, which can pull your score down by 50 points or more. If you pay $9,000 of that balance down over six months, your utilization drops to 30%. Based on FICO scoring patterns, that shift alone could raise your score by 40 to 80 points, even if nothing else about your credit changes.

Why Maxed-Out Cards Hurt More Than Many Readers Expect

Again, maxing out a credit card lowers your score because it signals that you can’t pay your bills with cash. Using a credit card regularly and paying off your balance each month is actually good for your credit score — it’s the inability to repay in full that concerns the lenders.

Carrying a balance rarely pays off, given that credit card annual percentage rates (APRs) are typically extremely high. Even if you can afford to make minimum payments on your card to keep it current, credit scoring models don’t take your income into account.

Does Paying Off Credit Card Debt Improve Your Score?

Yes, paying off credit card debt helps your credit score. Paying down your balances can raise your score by 10 to 50 points in a single billing cycle, depending on how much your utilization drops and how your overall credit profile looks. Plus, paying down your balance can improve your score within just a month or two. As soon as your credit card issuer reports your lower balance to the credit bureaus, you should see a credit score improvement.

This is why it’s so important to throw more than your minimum payment toward your bill each month. Every little bit you can lower your credit utilization will have a swift positive effect on your credit profile.

It’s worth noting, however, that if your credit is blemished with other negative activity, such as missed payments, paying off credit card debt probably won’t have as buoyant an effect on your credit score.

Payment History Still Matters More Than Debt Alone

As you can see, a high credit utilization can be devastating to your credit score. But it’s still not as important as your payment history, which makes up 35% of your FICO score, according to myFICO, making it the single biggest factor.

Credit card default is one of the worst things you can do for your credit health. Once your account is 30+ days late, it’s reported to the credit bureaus. Late payments can stay on your credit report for up to seven years from the date of the missed payment, according to the Consumer Financial Protection Bureau. In other words, mucking up your payment history can’t be fixed nearly as quickly as a high credit utilization.

To preserve your payment history, it’s wise to set all of your credit card accounts to autopay at least the minimum payment. That way, you won’t have to forget about paying your bills, and all accounts will stay current.

How To Reduce the Credit Damage From Credit Card Debt

Here are some simple action steps you can take to reduce the credit damage from credit card debt:

• Pay down your credit cards with the highest credit utilization. In addition to clocking your total credit utilization across all cards, credit bureaus also penalize you for having high utilization in relation to each individual credit line. Try to keep each credit card’s utilization below 30%, as well.

• Open a new credit card. On a similar note, it could be worthwhile to open another credit card to increase your total available credit. This will lower your credit utilization without paying down your balances. Weigh that benefit against the downsides, though: A new card triggers a hard inquiry and lowers your average account age, both of which can ding your score in the short term. And this may not be a good idea if you're an overspender.

How Applying for a New Credit Card Affects Your Score (Hard Inquiries)

Applying for a new credit card triggers a hard inquiry on your credit report. A hard inquiry usually lowers your score by fewer than 5 points, according to FICO, and stays on your report for two years — though it only affects your score for the first 12 months. Opening several cards in a short window can compound the impact, so space out applications by at least six months when you can.

Does Closing a Credit Card Hurt Your Credit Score?

Yes, closing a credit card can hurt your score in two ways. It lowers your total available credit, which pushes your utilization higher, and it can shorten your average age of accounts once the closed card falls off your report, which the credit bureaus generally do about 10 years after a closed account in good standing. If the card has no annual fee, keeping it open and using it for a small recurring charge is often the safer move.

Bottom Line

Credit card debt affects your credit score the most when your balances are high compared to your available credit. Worst-case scenario, your debts are so high that you’re unable to meet minimum monthly payments, and your accounts slip into delinquency.

Here’s the good news: If your credit score is suffering from high credit utilization, you can turn it around within a month or two by paying down those debts. Reducing your credit utilization can quickly boost your credit score.
