Your credit line is the maximum amount of money your card issuer will let you borrow at any one time

A credit line is a spending limit. When you open a credit card, the issuer sets a dollar amount you can charge to that card. You can spend anywhere from zero up to that limit, and whatever you spend becomes a balance you owe. Once you pay down that balance, the credit becomes available again — so a $5,000 credit line does not mean you can only spend $5,000 total, it means you can only have $5,000 charged to the card at any given moment.

The credit line is not the same as the amount of money in your bank account, and it is not information programs. Every dollar you charge is a debt you will owe to the card issuer, usually with interest if you do not pay the full balance by the due date.

Key Takeaways

  • Your credit line is the maximum balance you can carry on your card at one time, set by the issuer based on your credit history and income.
  • Spending up to your full credit line and then paying it back does not increase your line — only the issuer can raise it, either automatically or in response to a request.
  • Using a small portion of your credit line (typically under 30 percent) and paying on time helps your credit score; using most or all of it can lower your score.
  • Your credit line can be lowered or closed by the issuer if you miss payments, even if you have never used the full amount.

How the issuer decides your starting credit line

When you open a new credit card, the issuer pulls your credit report and score, checks your income, and looks at how you have handled debt in the past. People with higher credit scores and stable income typically receive higher starting credit lines. People with no credit history or a history of missed payments usually receive lower lines.

The issuer is not required to tell you how they calculated your line, and the same card can come with different lines for different people. A $500 line for one person and a $5,000 line for another person on the same card product is normal.

The difference between credit line and available credit

Your credit line is your maximum. Your available credit is what you have left to spend right now. If your credit line is $5,000 and you have charged $2,000, your available credit is $3,000.

When you make a payment, your available credit goes up by the amount you paid. If you pay $500 of that $2,000 balance, your available credit becomes $3,500. The credit line itself stays at $5,000 unless the issuer changes it.

How credit line affects your credit score

Credit bureaus track something called credit utilization — the percentage of your credit line you are actually using. If your line is $5,000 and you are carrying a $1,500 balance, your utilization is 30 percent. Utilization is one factor that affects your credit score.

Using less than 30 percent of your available credit is generally better for your score than using more. Using 80 or 90 percent of your line, or maxing it out entirely, signals to lenders that you are financially stretched and can hurt your score. This is true even if you pay your full balance on time every month — the score is based on the balance reported to the bureaus, which is usually your statement balance, not whether you paid it off.

Having a higher credit line can actually help your score, because the same balance becomes a smaller percentage. A $1,500 balance on a $5,000 line is 30 percent utilization, but the same $1,500 on a $10,000 line is only 15 percent.

How to request a credit line increase

Most card issuers let you request a higher credit line through their website or mobile app, usually in the account settings or customer service section. You can also call the number on the back of your card. The issuer will ask for your current annual income and may do a hard inquiry on your credit report, which can temporarily lower your score by a few points.

There is no may provide the issuer will approve your request. They may deny it, approve a smaller increase than you asked for, or approve the full amount. If you have missed payments or your income has dropped, the issuer is more likely to deny the request.

Some issuers automatically increase your credit line over time if you use the card responsibly and pay on time. You may receive a notice that your line has been raised without you asking. Other issuers never raise lines automatically and only increase them when you request it.

What happens if the issuer lowers your credit line

An issuer can lower your credit line at any time, even if you have never missed a payment. They might do this if your credit score drops, if you miss a payment on any credit account (not just this card), or if they decide to reduce risk across their customer base during economic downturns.

If your balance is higher than your new, lower credit line, you are not required to pay the difference when ready — you can continue to pay down the balance over time. However, you cannot charge anything new until your balance falls below the new limit.

An issuer can also close your account entirely, which means you can no longer use the card but you still owe any balance you have charged. A closed account can hurt your credit score because it reduces your total available credit and changes the age of your credit mix.

Credit line versus cash advance limit

Some credit cards have a separate cash advance limit, which is different from your regular credit line. The cash advance limit is the maximum amount you can withdraw as cash from an ATM or get from a bank teller using your credit card. This limit is often lower than your regular credit line — you might have a $5,000 credit line but only a $1,000 cash advance limit.

Cash advances come with higher fees and higher interest rates than regular purchases, and interest starts accruing when ready (there is no grace period like there usually is for purchases). For this reason, cash advances are generally more expensive than charging a purchase to your card.

Frequently Asked Questions

Can I spend more than my credit line?

No. Once you reach your credit line, the card will be declined if you try to charge more. Some issuers offer an over-limit option that lets you exceed your line for a fee, but this is rare and usually only available to customers with good payment history.

Does my credit line reset every month?

Your credit line itself does not reset. However, your available credit resets based on your payments. If you pay your full balance, your available credit returns to your full credit line. If you carry a balance, your available credit is reduced by that amount until you pay it down.

Will requesting a credit line increase hurt my credit score?

The request itself does not hurt your score, but the hard inquiry the issuer does may lower your score by a few points temporarily. If the issuer approves and increases your line, the higher line can actually help your score over time by lowering your utilization percentage.

What if I have a $0 balance but my available credit is less than my credit line?

This usually means the issuer has temporarily frozen part of your line, often due to suspicious activity or a missed payment on another account. Contact the issuer to find out why and what you need to do to restore access to the full line.

Can I use my credit line to pay bills or transfer money to my bank account?

You cannot directly transfer your credit line to a bank account. You can use your card to make purchases or get a cash advance, but cash advances cost more and come with higher interest rates. Some cards offer balance transfer options to move debt from another card, but this is different from accessing your credit line as cash.
