A line of credit is an approved amount of money you can borrow from as needed instead of receiving a lump sum all at once. The lender sets a credit limit, and you draw against it when you need funds. Interest generally applies to the amount you have borrowed, not to the unused portion of the limit.
Repayment terms, interest rates, fees, and access methods depend on the product and lender. Some lines of credit are backed by collateral, such as a home. Others are unsecured. Many allow you to reuse credit as you repay the balance, while some limit when new funds can be drawn.
What is a Line of Credit?
A line of credit is an agreement with a lender that lets an approved borrower access funds up to a set limit when needed.
Three numbers are useful to understand:
- Credit limit: The maximum amount the lender has approved you to borrow.
- Outstanding balance: The amount you currently owe based on what you have drawn and not yet repaid.
- Available credit: The amount that remains available to borrow.
If your credit limit is $10,000 and you owe $2,000, your available credit is about $8,000, subject to your account terms.
Many lines of credit are revolving. As you repay the principal, that amount can become available to borrow again. Some accounts have a defined draw period or expiration date, so new borrowing may not remain available indefinitely.
How Does a Line of Credit Work?
The process varies by lender and product, but the basic structure is similar.
You apply, and the lender reviews information such as your credit history, income, or business finances. If approved, you receive a credit limit. You do not have to borrow the full amount at once. Instead, you can draw money as needed through the methods supported by the account.
Interest is usually charged on the amount you have drawn rather than the full credit limit. Once you carry a balance, the lender may require a minimum payment. On a revolving account, repaid principal can usually become available again while the account remains open and in good standing.
Hypothetical example: A borrower has a $10,000 revolving line of credit and draws $3,000 for a home repair. The outstanding balance becomes $3,000, leaving about $7,000 available, subject to the account terms. Interest applies to the borrowed amount under the agreement. If the borrower repays $1,000 of principal, that amount can generally become available to borrow again.
Actual limits, rates, fees, and repayment rules depend on the lender and product.
Revolving vs. Non-Revolving Credit
Revolving credit allows a borrower to draw funds, repay them, and borrow again while the account remains open and within its terms. Credit cards are a familiar example, and many personal and business lines of credit also work this way.
With non-revolving credit, repaid amounts generally do not become available again under the same agreement.
Some revolving accounts also have time limits. A draw period is the period during which new funds can be borrowed. After it ends, an account may enter a repayment period, when new draws stop and the remaining balance must be repaid.
Other accounts may have renewal or maturity dates. What happens at that point depends on the credit agreement.
Secured vs. Unsecured Lines of Credit
The main difference between secured and unsecured lines of credit is collateral.
A secured line of credit is backed by an asset pledged as collateral. Depending on the product, that asset could be a home or another qualifying asset. If the borrower defaults, the lender may have rights against the pledged collateral under the credit agreement and applicable law.
An unsecured line of credit does not require the borrower to pledge a specific asset. Because the lender does not have that collateral protection, approval and pricing may depend more heavily on credit history, income, cash flow, existing debt, repayment history, and overall creditworthiness.
An unsecured line may have a higher interest rate, a lower credit limit, or stricter approval requirements than a comparable secured product. The actual terms depend on the lender and the borrower’s financial profile.
Unsecured debt does not mean a lender has no options if the borrower stops paying. The lender may still use collection procedures or legal remedies where permitted by law.
A home equity line of credit, or HELOC, is a common example of a secured line because the borrower’s home serves as collateral.
Common Types of Lines of Credit
Personal Line of Credit
A personal line of credit is intended for individual borrowers rather than businesses. It is often unsecured, although secured products also exist.
Once approved, the borrower receives a credit limit and can draw funds as needed. Interest generally applies to the amount borrowed.
Personal lines may require minimum payments when a balance is outstanding. Some lenders also charge setup, maintenance, or transaction fees. Eligibility and account terms vary, and not every bank or credit union offers this type of credit.
Home Equity Line of Credit
A home equity line of credit is generally secured by equity in the borrower’s home.
Many HELOCs have a draw period during which funds can be borrowed. After the draw period ends, the account may enter a repayment period when new draws are no longer allowed and the remaining balance must be repaid.
Variable interest rates are common with HELOCs, so borrowing costs and payments can change over time. Because the home serves as collateral, failure to repay can put the property at risk, subject to the agreement and applicable law.
Credit limits, draw periods, repayment terms, and rate structures vary by lender.
Business Line of Credit
A business line of credit gives a company access to funds for short-term or changing financing needs.
Businesses may use one for:
- Working capital
- Inventory
- Seasonal expenses
- Temporary cash-flow gaps
- Recurring operating costs
Business lines of credit can be secured or unsecured. Some are backed by assets such as receivables or inventory. Others rely more heavily on the company’s credit history, revenue, and cash flow.
The U.S. Small Business Administration also backs certain line-of-credit programs for eligible small businesses, although requirements depend on the program and participating lender.
Line of Credit vs. Personal Loan
The main difference is how the money is provided.
A personal loan generally gives the borrower a fixed lump sum that is repaid over a set period. A revolving line of credit lets the borrower make repeated draws up to the approved limit while the account remains open and within its terms.
| Line of Credit | Personal Loan | |
|---|---|---|
| How funds are received | Drawn as needed up to the limit | Received as one lump sum |
| Can you borrow more than once? | Often yes, if revolving | A new loan is generally required |
| Interest | Generally based on the outstanding amount drawn | Generally based on the outstanding loan balance after funding |
| Repayment | Varies and may include minimum payments | Usually follows a set repayment schedule |
| Available credit | Can replenish as principal is repaid on revolving accounts | Does not replenish |
| Typical use | Ongoing or uncertain expenses | A specific expense with a known borrowing amount |
Neither option is automatically better. A personal loan may suit a known expense when a fixed borrowing amount and repayment schedule are useful. A line of credit may be more suitable when borrowing needs are uncertain or spread over time.
Line of Credit vs. Credit Card
A line of credit and a credit card can both be forms of revolving credit. Each may have a set credit limit, and interest may apply to unpaid balances.
The main differences are practical. Credit cards are designed for purchases and may include features such as rewards, purchase protections, and a grace period on qualifying purchases. A line of credit is often accessed through a transfer, check, or online request and may not offer the same purchase features.
Rates and fees vary by product and lender. It is not accurate to assume that a line of credit always has a lower rate than a credit card, or the reverse. Some lines charge fees for drawing funds, while some credit cards have different fees for purchases, cash advances, or other transactions.
Interest, Fees, and Other Costs
Costs vary by lender and product. Depending on the account, a line of credit may involve:
- Interest on borrowed funds
- Origination or setup fees
- Annual fees
- Maintenance fees
- Transaction or draw fees
- Inactivity fees
- Late-payment fees
- Other account-specific charges
Not every account charges every fee.
Rates may be fixed or variable. A variable rate can move up or down according to the terms of the credit agreement. Because rates and fees differ between lenders and may change over time, borrowers should check the current terms of a specific offer rather than assume a standard cost.
When Can a Line of Credit Be Useful?
A line of credit may be useful when borrowing needs are uncertain, recurring, or spread over time.
Examples include:
- Bridging a temporary gap between income and expenses
- Covering an unexpected but manageable expense
- Paying for a project when the final cost is uncertain
- Managing seasonal business costs
- Supporting short-term working-capital needs
A line of credit is still debt. Using it for discretionary spending carries the same obligation to repay the balance, interest, and any applicable fees.
Advantages and Disadvantages
Possible advantages:
- You can borrow only the amount you need
- Funds remain available without taking the full credit limit upfront
- Interest generally applies to the amount borrowed
- Repaid principal may become available again on revolving accounts
- It can suit expenses that are uneven or difficult to predict
Possible disadvantages:
- Variable rates can increase borrowing costs
- Fees may apply
- Easy access to funds can encourage unnecessary borrowing
- Missed payments can lead to fees and credit consequences
- Secured lines put pledged collateral at risk
- A lender may reduce, freeze, suspend, or close a line where permitted by the agreement and applicable law
What Do Lenders Consider When You Apply?
Approval standards vary, but lenders commonly review factors such as:
- Credit history and credit score
- Income
- Business revenue or cash flow
- Existing debt and financial obligations
- Ability to repay
- Collateral for secured lines
- Previous repayment history
- Business financial records where applicable
There is no universal credit score or income level that guarantees approval. Requirements depend on the lender and the specific product.
Questions to Ask Before Opening a Line of Credit
Before accepting an offer, check the terms that affect how much the account could cost and how it can be used:
- What is the interest rate?
- Is the rate fixed or variable?
- How is interest calculated?
- What fees apply?
- What is the credit limit?
- What is the minimum required payment?
- Is collateral required?
- Can the lender freeze, reduce, or close the line?
- Are there restrictions on how the funds can be used?
- Is there a draw period?
- What happens when the draw period ends?
- Does the account expire or require renewal?
- What happens if a payment is missed?
Frequently Asked Questions
Is a line of credit a loan?
Yes, broadly speaking. It is a form of borrowing in which a lender makes credit available up to a set limit instead of providing one lump sum upfront.
Do you pay interest on the full credit limit?
Generally, no. Interest is usually charged on the amount you have borrowed, not on unused available credit. The exact calculation depends on the account terms.
Can you reuse a line of credit after repayment?
Usually, if the line is revolving. Repaid principal can generally become available again while the account remains open and in good standing.
Is a line of credit secured or unsecured?
It can be either. HELOCs are generally secured by a home. Personal lines are often unsecured, while business lines may be secured or unsecured depending on the lender and product.
Does a line of credit affect your credit?
It can. Lenders may report account balances, payment history, and other activity to credit bureaus, which can affect a borrower’s credit history and score.
What is the difference between a line of credit and a credit card?
Both can provide revolving credit up to a set limit. Credit cards are mainly designed for purchases, while a line of credit is commonly accessed through transfers, checks, or other account methods.
What is the difference between a line of credit and a personal loan?
A personal loan generally provides one lump sum that is repaid over a set period. A revolving line of credit allows repeated borrowing up to the approved limit while the account remains available.
What happens if you do not use your line of credit?
It depends on the account. Some lenders may charge inactivity fees, reduce an unused limit, or close an inactive line. Other accounts may have no penalty for going unused.
Can a lender reduce or freeze a line of credit?
Yes, if permitted by the credit agreement and applicable law. The circumstances in which this can happen vary by product and lender.
Before opening a line of credit, compare the interest rate, fees, repayment terms, collateral requirements, credit limit, and any restrictions on accessing the funds. These details can vary between products, so the account terms are the most reliable guide to what you are agreeing to.
