A credit card is not the same as a line of credit, even though both let you borrow money
A credit card is a specific type of payment tool issued by a bank or card company. You use it to make purchases, and you receive a bill each month for what you spent. A line of credit is a broader category of borrowing arrangement where a lender gives you access to a pool of money you can draw from as needed. A credit card is one example of a line of credit, but not all lines of credit are credit cards. The key difference is how you access the money and what you use it for.
Credit cards come with a physical or digital card you present to merchants. Lines of credit often work differently — you might write checks against the account, transfer money to your bank account, or access funds through an app. A home equity line of credit (HELOC), for example, lets you borrow against your home's value but doesn't come with a card. A personal line of credit from a bank works similarly. Credit cards are designed for everyday purchases; other lines of credit are often meant for larger expenses or ongoing access to cash.
Key Takeaways
- A credit card is a type of line of credit, but the term "line of credit" covers many borrowing arrangements that are not cards.
- Credit cards come with a card you use at merchants; other lines of credit typically use checks, transfers, or direct draws to your bank account.
- Both charge interest on the balance you carry, but credit cards often have higher interest rates than other lines of credit.
- Credit cards report to the three major credit bureaus and affect your credit score; some lines of credit do not report to bureaus at all.
How a credit card works as a line of credit
When you open a credit card, the card company sets a credit limit — the maximum amount you can borrow. That limit is your line of credit. You can spend up to that limit, and the amount you owe at any moment is called your balance. Each month, you receive a statement showing what you spent and how much you owe. You can pay the full balance, make a minimum payment, or pay anything in between.
The interest you pay depends on your annual percentage rate (APR), which is set by the card company based on your credit history and the card's terms. If you carry a balance from one month to the next, interest accrues daily on the unpaid amount. If you pay the full balance by the due date, most credit cards charge no interest. This is where credit cards differ from many other lines of credit — you have the option to borrow interest-free if you pay on time.
Your credit card issuer reports your account activity to Equifax, Experian, and TransUnion — the three major credit reporting agencies. This means your credit card balance, payment history, and credit limit all affect your credit score. Other lines of credit may or may not report to these bureaus, depending on the lender.
Other types of lines of credit and how they differ from cards
A home equity line of credit (HELOC) lets you borrow against the equity you have built in your home. Instead of a card, you typically access the money by writing checks or requesting transfers. HELOCs usually have lower interest rates than credit cards because your home secures the loan. If you stop paying, the lender can foreclose.
A personal line of credit from a bank or credit union works like a credit card in that you can borrow up to a set limit and pay interest on what you use. However, you usually access the money through bank transfers or checks rather than a card. Personal lines of credit often have lower APRs than credit cards, especially if you have good credit.
A business line of credit works the same way but is issued to a business rather than an individual. A student line of credit is specifically for education expenses. The mechanics are similar across all of these: you have a limit, you draw funds as needed, you pay interest on the balance, and you make monthly payments. The main differences are the purpose, the interest rate, and how you access the money.
Interest rates and fees: credit cards versus other lines of credit
Credit card APRs typically range higher than other lines of credit because credit cards are unsecured — the lender has no collateral if you don't pay. A HELOC is secured by your home, so the lender's risk is lower and the interest rate is usually lower. Personal lines of credit fall somewhere in the middle. The exact rate you receive depends on your credit score, income, and the lender's policies.
Credit cards also charge fees that other lines of credit may not. An annual fee is a yearly charge some cards impose just for holding the account. A late fee is charged if you miss a payment deadline. A foreign transaction fee applies if you use the card outside the United States. A cash advance fee is charged if you withdraw cash using the card. Other lines of credit typically do not charge these types of fees, though they may charge an origination fee when you first open the account.
If you carry a balance on a credit card and make only the minimum payment, interest accrues and compounds, meaning you pay interest on interest. The longer you carry the balance, the more you pay in total. Other lines of credit work the same way — interest compounds on any unpaid balance — but the lower starting rate means the total cost is often less.
How credit limits work on cards versus lines of credit
Your credit card limit is set by the issuer based on your credit score, income, and payment history. You can request a higher limit, and the issuer may grant it if your credit has improved or your income has increased. Some issuers raise your limit automatically if you make on-time payments. Your limit does not change unless you or the issuer take action.
A line of credit limit works the same way — it is set when you open the account and can be raised or lowered based on your creditworthiness and the lender's policies. However, some lines of credit have a draw period and a repayment period. During the draw period (often 5 to 10 years for a HELOC), you can borrow and repay as you wish. During the repayment period, you can no longer draw new funds and must pay down the balance. Credit cards do not have a set repayment period — you can keep using the card as long as the account is open and you make payments.
How credit card and line of credit payments affect your credit score
Credit card issuers report your account to the credit bureaus every month. This means your payment history, credit utilization (the percentage of your limit you are using), and account age all factor into your credit score. Paying on time every month helps your score. Carrying a high balance relative to your limit hurts your score, even if you make the minimum payment.
Not all lines of credit report to the bureaus. Some personal lines of credit, business lines of credit, and HELOCs do not appear on your credit report at all. This means they do not help or hurt your credit score. However, if you miss a payment on any line of credit, the lender may report the delinquency to the bureaus, which will damage your score regardless of whether the account normally reports.
If you close a credit card, the account remains on your credit report for up to seven years, and closing it can lower your score because it reduces your total available credit. Closing a line of credit has a similar effect. The impact is usually temporary, but it is worth considering before you close an account you have held for a long time.
When to use a credit card versus another line of credit
A credit card makes sense for everyday purchases, recurring bills, and situations where you want the option to pay interest-free if you pay the full balance quickly. Credit cards are also useful if you want to build credit history, since they report to the bureaus. The downside is the higher interest rate if you carry a balance and the temptation to overspend because the limit is separate from your bank account.
A personal line of credit or HELOC makes sense if you need access to a larger amount of money for a specific purpose — home repairs, medical bills, or a business expense — and you want a lower interest rate than a credit card offers. You access the money as you need it, so you only pay interest on what you actually use. The downside is that the application process is usually longer and more rigorous than opening a credit card.
If you have both a credit card and another line of credit, use the card for smaller, frequent purchases and the line of credit for larger, less frequent needs. This approach lets you take advantage of the credit card's reporting to the bureaus while keeping your credit utilization low, which helps your score.
Frequently Asked Questions
Is every line of credit a credit card?
No. A credit card is one type of line of credit, but lines of credit include HELOCs, personal lines of credit, business lines of credit, and others. All credit cards are lines of credit, but not all lines of credit are credit cards.
Do I pay interest on a credit card if I pay the full balance?
No. If you pay the entire balance by the due date, no interest is charged. Interest only accrues on the unpaid portion of your balance. This is different from many other lines of credit, where interest begins accruing as soon as you draw funds.
Can I lose access to my line of credit if I don't use it?
Credit card issuers may close inactive accounts after a period of non-use, typically six months to a year. Other lines of credit have similar policies. Closing an account can lower your credit score because it reduces your available credit. To keep an account open, use it occasionally and pay on time.
What happens if I exceed my credit limit?
Most modern credit cards decline transactions that would exceed your limit. If a transaction is approved and pushes you over the limit, you may be charged an over-limit fee (though these are less common now). Exceeding your limit can also lower your credit score because it increases your credit utilization above 100 percent.
Do all lines of credit report to credit bureaus?
No. Credit cards almost always report to the three major bureaus. Many personal lines of credit, HELOCs, and business lines of credit do not report unless you miss a payment. Ask your lender whether they report to the bureaus before you open the account if credit-building is important to you.
