What Is a Credit Limit?
In plain English
A credit limit is the maximum dollar amount your lender allows you to borrow on a revolving credit account. It is determined when you open an account based on factors like your credit score, income, and existing debt. Spending above your limit may result in declined transactions, over-limit fees, or damage to your credit score.
How Is a Credit Limit Determined?
Lenders set credit limits by evaluating your credit score, income, debt-to-income ratio, credit history, and existing obligations. Higher credit scores and incomes typically result in higher limits. Secured credit cards use your deposit as the limit. Lenders may also offer automatic limit increases over time as you demonstrate responsible repayment behavior.
How Does Your Credit Limit Affect Your Credit Score?
Your credit limit directly influences your credit utilization ratio. A higher limit means you can carry the same balance at a lower utilization percentage, which is better for your score. For example, a $1,000 balance on a $2,000 limit card is 50% utilization, but the same balance on a $5,000 limit card is only 20%. Requesting limit increases — without adding debt — can improve your score.
How Can You Request a Credit Limit Increase?
Most issuers allow you to request an increase online, by phone, or through their app. You may need to provide updated income information. A hard inquiry may or may not be conducted — ask the issuer beforehand if you are concerned about your score. Having a track record of on-time payments and low utilization significantly improves your chances of approval.
Frequently asked questions
What happens if you go over your credit limit?
Most issuers will decline the transaction that would push you over the limit, unless you have opted into over-limit coverage. If approved, you may incur an over-limit fee and your credit score can be harmed due to a spike in utilization. It is best to stay well below your limit at all times.
Does requesting a credit limit increase hurt your score?
It depends on the issuer. Some conduct a hard inquiry when you request an increase, which can temporarily lower your score by a few points. Others use a soft inquiry, which has no impact. Ask your issuer which type of inquiry they perform before submitting your request.
