Can a Credit Limit Increase Help Your Credit Score? Here’s When It Might—and When It Won’t

When it comes to credit, no two situations are the same. But in many cases, qualifying for a higher credit limit has the potential to improve your credit scores—sometimes significantly.

The reason a higher credit limit may boost your credit score comes down to one of the most important factors in your credit score: your credit utilization ratio. This metric measures the relationship between your credit card limits and balances. When your credit limit goes up (and your spending stays the same), your utilization ratio improves. And a lower utilization ratio has the ability to give credit scores a helpful boost.

That said, credit scoring isn’t always straightforward. Sometimes a credit limit increase might help your credit score, have no impact, or—in rare cases—trigger a temporary credit score decline.

Read below for a breakdown of all the ways credit limit increases could affect your credit score and why. Plus, discover tips on how to decide if asking for a credit limit increase is the right smart move for you.

How a Higher Credit Limit Could Improve Your Credit Score

Every credit report is different. But because of the way credit scores work, one of the most actionable ways to earn and keep good credit is to keep your utilization ratio low.

Credit utilization is a key factor in the amounts owed category of your FICO® Score. (The entire amounts owed category is responsible for 30% of your FICO Score.) The lower your utilization, the better especially when it comes to revolving credit cards.

Paying down credit card debt is typically the best way to reduce credit utilization. But if doing so isn’t financially realistic, asking for a credit limit increase might be a useful workaround—as long as you don’t increase your spending.

Example: How a Higher Credit Limit Affects Utilization

Let’s say you have a credit card account with the following balance and limit.

Original Credit Limit: $5,000
Account Balance on Credit Report: $1,000
Utilization Ratio: $1,000 (Balance) ÷ $5,000 (Limit) = 0.20 X 100 = 20%

Now, imagine your credit card issuer doubles your credit limit.

Increased Credit Limit: $10,000
Account Balance on Credit Report (Same as Above): $1,000
New Utilization Ratio: $1,000 (Balance) ÷ $10,000 (Limit) = 0.10 X 100 = 10%

In this example, you cut your utilization in half simply by asking for a higher credit limit on the account. That kind of change is meaningful, and could have a noticeable impact on your credit score.

Understanding Credit: Many financial experts suggest maintaining a credit utilization ratio below 30%, but lower is better. According to FICO, the average credit utilization ratio of a credit score “high achiever” (aka someone with a perfect 850 FICO® Score) was 4.1%.¹

When a Credit Limit Increase Might Not Help Your Credit Score

While a credit limit increase is often beneficial, it’s not a guaranteed credit score booster. If you already have low credit card balances and your utilization ratio is in excellent shape, increasing your limit might not impact your score much, if at all. There are only a certain number of credit score points available to earn in each credit score category, after all.

Credit scoring models like FICO and VantageScore weigh multiple factors, including:

Payment history
Amounts owed (including credit utilization)
Length of credit history
Credit mix
New credit activity

So even though utilization matters, it’s just one part of a bigger picture where your credit score is concerned.

CreditWriter Tip:
Payment history is worth 35% of your FICO® Score. Making your payments on time—every time—is the most important step toward earning good credit.

Can Asking for a Credit Limit Increase Hurt Your Credit Score?

In a few scenarios, requesting a higher credit card limit could trigger a credit score drop. But if any credit score damage happens, the effect tends to be minor.

When you ask your credit card issuer for a higher credit limit, it may want to check your credit report before deciding whether to approve or deny the request. And after this type of credit review, a hard inquiry could appear on your credit report. Hard credit inquiries may lower your credit score, but the impact tends to be minimal as long as you don’t apply for too much new credit in a short period of time.

Understanding Credit: Hard inquiries don’t take a specific number of points away from your credit score because that’s not how credit scoring works. Still, most people see a drop of less than five points off their FICO Score from the addition of one new hard inquiry on their credit report.

After 24 months, the credit bureaus remove hard inquiries from your credit report. And FICO only considers hard inquiries in your scores for a 12-month period. However, if your card issuer denies your request for a credit limit increase, you’ll potentially take a hit from the inquiry without any benefit to your credit utilization ratio.

If you’re unsure about whether your credit card issuer will perform a hard credit pull when you ask for a higher credit limit, you can always ask for more information. Then, you’ll be able to decide whether you’re comfortable moving forward once you have all the facts.

How to Manage a New Credit Limit Increase

A high credit limit can be a helpful credit-building tool. But it’s only beneficial if you manage the increased borrowing power wisely. If you’re likely to overspend once you have more available credit, a higher credit limit could backfire. Then, instead of a lower credit utilization ratio you could be facing more debt, more interest, and the possibility of lower credit scores over time.

That being said, here are some tips on ways to keep your new credit limit increase working for you.

Keep balances low. Resist the temptation to charge more money on your credit card just because you can. Follow a budget, track spending, and avoid spending more than you can afford to pay off in a single billing cycle.
Pay on time, every time. Remember that payment history is the most important credit score factor. On-time payments are essential to protect your credit scores.
Start paying down your credit card debt. Use proven debt elimination methods, like the debt avalanche or debt snowball, to pay down credit card balances faster, save money on interest, and reduce your utilization further.

Remember, your credit cards are tools. If you use them responsibly, they can help you build good credit and gain access to valuable benefits. But they’re only worthwhile if you stay in control of how you use them.

Moving Forward

For many people, a credit limit increase may be a helpful way to reduce credit utilization and (possibly) boost credit scores while you work to pay down credit card debt. But as with any credit strategy, results depend on your individual credit profile and financial habits.

If you’re thinking about asking for a higher credit limit, make sure it aligns with your overall goals. Above all, commit to keeping your spending in check and using your new limit responsibly. The last thing you want to do is trade a short-term credit boost for a long-term debt problem.
