How do lines of credit work?
A line of credit is technically a type of loan. Unlike with a traditional personal loan, you’ll only pay interest on the amount of money you use. When you’re approved for a line of credit, the lender agrees to give you access to a specified amount of money. You can spend as much of the maximum amount as you’d like. Once you pay it back, the amount of credit you have adjusts accordingly. This is known as revolving credit.
With a line of credit, you only pay interest on what you borrow, even if the money you’re approved for exceeds this amount.
For example, say you have a $25,000 line of credit to help you remodel your home. You use $4,000 on an initial expense. You would then owe $4,000 plus interest, and you would have $21,000 remaining on the line of credit. Once you pay back what you’ve borrowed, you’ll again have access to your full line of credit.
Depending on how the lender structures the line of credit, you may have a draw period that lasts from three to 10 years, followed by a repayment period of equal length where you can no longer borrow and must pay off the debt.
To get a line of credit, a borrower must be approved by the lender. Approval usually depends on the applicant's credit score, credit history, employment, income and current debts.
Line of credit uses
Typically, a line of credit isn't intended to fund a significant one-time purchase like a car or a down payment on a home. This type of loan works best when the total cost of a project is somewhat undefined and you might need to withdraw funds a handful of times throughout the course of a few years. Having a line of credit can help you avoid taking out multiple personal loans and give you greater overall flexibility.
Businesses may use lines of credit to help them take advantage of investment opportunities, expand their operations, purchase new equipment and meet capital needs. Or, a line of credit may be a good fit if you need to smooth out irregular income from a seasonal business, want access to funds for emergency use, are remodeling your home or need robust overdraft protection.

Line of credit terms and fees
Here are some of the key line of credit terms and fees to be aware of:
Line of credit terms
Before taking out a line of credit, you should know the following terms.
- Draw period: This refers to the period of time where you can borrow funds, up to your approved credit limit. Draw periods generally last three to 10 years.
- Repayment period: After the draw period ends, the repayment period will start. This is when you’ll pay back the funds you’ve borrowed. Repayment periods are longer than draw periods and typically last anywhere from five to 20 years.
Line of credit fees
Some common fees you might see when looking at different lines of credit include:
- Monthly or annual account maintenance fees
- Origination fees
- Transaction fees
- Over-limit fees
- Late fees
Line of credit vs. loans
With a loan, you typically receive a lump sum and have a fixed amount of time to pay it back, plus interest and fees. A line of credit lets you take out up to a certain amount of money at any given time, but you only pay interest on the portion of the money you withdraw.
A line of credit usually has a variable interest rate, while a personal loan tends to have a fixed interest rate.
Interest rates
A line of credit often has a variable interest rate that adjusts according to market conditions. When interest rates are high, the cost of accessing money in a line of credit increases. In most cases, personal loans have fixed interest rates, so the borrower's monthly payment stays the same throughout the term of the loan.
Qualifications and approval
Whether you’re trying to get a line of credit or a loan, your lender will collect your personal information and look at your credit history to evaluate how much of a risk you pose. Applicants with good to excellent credit pay less interest than applicants with poor credit or no credit history.
The process of getting approved for a line of credit is similar to applying for a loan and may take about the same amount of time, depending on the lender.
Types of lines of credit
The main two types of lines of credit are unsecured and secured lines of credit.
Unsecured lines of credit
With an unsecured line of credit, there is no collateral, so the lender can’t take any of your assets if you default, or fail to repay your loan. For this reason, you may have a tougher time getting approved if you don’t have a good credit score.
A secured line of credit might give you access to more funds and a lower interest rate.
Secured lines of credit
With a secured line of credit, the lender may be more flexible when it comes to approving your loan application because the loan is backed by collateral. You may also pay less interest with a secured line of credit than you would with an unsecured line of credit.
Since secured lines of credit require collateral, the lender can take your secured assets if you fail to repay the loan. For instance, a home equity line of credit (HELOC) uses your home as collateral. If you fail to pay back the loan as agreed, the lender could start the foreclosure process.
One advantage to a HELOC is that you may be able to deduct the interest on your taxes if you use the money to improve your home. Consult a tax expert so you understand how deductions may apply to your situation.
What to consider before taking out a line of credit
Like other loan types, a line of credit can be a useful financial tool. You only borrow and pay interest on the money you need, unlike with a personal loan. And the interest rate on a line of credit is usually lower than on a credit card, another form of revolving credit. Lenders offer both unsecured and secured lines of credit and let you use the funds for many purposes.
However, because the interest rate is usually variable, it can be difficult to predict future borrowing costs. Lenders may also charge a variety of fees, such as annual fees and late fees. Also, the easy access to credit once you open the line of credit may lead to overspending.
Is a line of credit right for you?
If you understand how a line of credit works and use it appropriately, it could be the right type of loan for you. A Nebraska resident who left a review on ConsumerAffairs appreciated how quickly she was able to access funds.
“Once approved, I requested the amount needed for my line of credit,” they said. “I requested some money on a Friday and had my cash by Monday. Keep in mind, this credit is going to cost me, but the rates and fees are clear if you read them.”
FAQ
What is the risk of using a line of credit?
Some of the risks of using lines of credit include variable interest rates and fees. For example, some lines of credit include annual fees or maintenance fees, transaction fees, late fees and over-limit fees.
How do you pay back a line of credit?
After your draw period ends, you’ll need to pay back your line of credit before the end of the repayment period. You’ll generally have to make a minimum monthly payment, but you can pay off the balance at your own pace as long as it’s paid in full within the repayment timeline.
Which is better, a personal loan or a line of credit?
Whether a personal loan or a line of credit is better for you will largely depend on whether or not you know the full cost of your desired expenses upfront. If you do, a personal loan tends to be a better choice, whereas if you don’t know how much you’ll need, a line of credit will likely be a better option.
Bottom line
A line of credit can be a powerful tool to help you reach your goals if you want access to funds in case there's a financial emergency or want to start a project and are unsure of the total costs. However, like any type of credit, a line of credit can be expensive due to associated fees like account management charges and loan origination fees.
If you’re interested in getting a line of credit, talk with a representative from your bank or credit union to see if it offers this type of loan. No matter what type of loan you get, be sure to shop around to get the lowest rates and best terms.
