What a loan is
A loan is a single extension of credit. The lender advances a lump sum, and you agree to repay that principal plus interest under a set schedule. Personal loans, auto loans, student loans, and mortgages usually work this way. Because the repayment schedule is fixed at the start, a loan can make budgeting simpler. You know the payment and the payoff timeline if you keep the agreed terms. For an overview of common loan structures, see this guide to what a loan is. Under the Truth in Lending Act, the lender must disclose key terms, including the APR, before you sign. You can review the regulation through the Truth in Lending Act rules.
A loan may be secured or unsecured. A secured loan uses collateral such as a car or home, so the lender can take the property if you default. An unsecured loan relies mainly on your credit and income, so it may carry different eligibility rules. The CFPB offers consumer information on personal loans and other borrowing products.
What a line of credit is
A line of credit is a reusable borrowing limit. You can draw funds when needed, repay them, and draw again during the draw period, as long as you stay within the limit and meet the terms. A credit card is a familiar revolving line of credit. A personal line of credit and a home equity line of credit are other examples. See what a personal line of credit is and how to get a HELOC for related details.
Interest usually applies only to the amount you actually draw, not the full limit. That can make a line of credit useful for irregular expenses, but it also means your payment can change as the balance and rate change. The CFPB explains revolving credit and other options in its Ask CFPB answers.
Key differences at a glance
The simplest way to compare a line of credit vs loan is to look at how funds are advanced, how interest is charged, and how repayment works.
| Feature | Line of credit | Loan |
|---|---|---|
| Funds advanced | You draw as needed up to a limit | You receive a lump sum at closing |
| Reuse | Funds can be reused after repayment | Usually cannot be reused after payoff |
| Interest | Charged on outstanding balance | Charged on full principal from disbursement |
| Payment | Can vary with balance or rate | Often fixed if fixed-rate |
| Term | Draw period plus repayment period | Set repayment term |
| Best use | Ongoing or uncertain expenses | One-time planned expense |
This table is a general guide, not a rule for every product. A lender can structure a loan or line of credit in different ways, so read the agreement and disclosures. The FTC credit and loans page has more on comparing credit offers.
How repayment and interest work
With a loan, repayment usually follows an amortization schedule. Part of each payment goes to interest and part to principal. Early payments may go more toward interest, and later payments more toward principal. If the loan has a fixed rate, the payment stays the same. If it has a variable rate, the payment can change when the rate changes. The CFPB provides a consumer loan overview that explains these basics.
With a line of credit, repayment depends on the draw and the terms. Some lines require interest-only payments during the draw period, then a repayment period with principal and interest. Others require a minimum payment based on the balance. Because the balance can rise or fall, the monthly payment can be less predictable. A line of credit may also have a maturity date, when the entire remaining balance becomes due. You can estimate payments with a personal loan calculator, but read the lender's actual terms.
Costs, risks, and credit impact
Both loans and lines of credit can charge interest and fees. A lender may charge an origination fee, annual fee, late fee, or closing costs, depending on the product. For a line of credit, there may be a fee to open the line or a fee for inactivity. The Truth in Lending Act requires disclosures that help you compare the cost of credit, including the APR. You can review those rules at the CFPB regulation page.
Risk also differs. A loan with fixed payments can be easier to budget, but you owe the full amount even if you no longer need the money. A line of credit offers flexibility, but the lender may reduce or freeze the line if your financial situation changes. A home equity line of credit puts your home at risk if you cannot repay, as explained in this guide to home equity line of credit vs loan.
Both can affect your credit reports and scores. Payment history, balances, and account types can matter. You can check your reports from the nationwide credit reporting companies at AnnualCreditReport.com, the site authorized by federal law. The CFPB also explains credit reports and scores.
When a loan may fit better
A loan may be a better fit when you need a specific amount for a one-time expense and want a predictable repayment plan. Examples include consolidating existing debt, paying for a major purchase, or covering a project with a known cost. A fixed-rate installment loan can make it easier to plan your monthly budget because the payment and payoff timeline are set at the start. See what installment loans are for more detail.
A loan can also be simpler to manage. Once you receive the funds, you do not need to decide when to draw or how much to draw. You simply make the scheduled payments. If you are comparing debt consolidation options, a debt consolidation calculator can help you review possible payments, but it cannot predict approval or final terms.
When a line of credit may fit better
A line of credit may fit better when your expenses are irregular, ongoing, or hard to predict. You can draw only what you need and avoid paying interest on the unused portion, subject to the lender's terms. That structure can be useful for home repairs, seasonal business costs, or a cash-flow gap. A personal line of credit may be unsecured, while a HELOC is secured by your home. Compare those paths in HELOC vs personal loan.
Flexibility has tradeoffs. You may pay a variable rate, and your payment can rise if you draw more or if the rate increases. A line of credit may also have a draw period that ends, followed by a repayment period. If you cannot repay at maturity, you could face collection or, for a secured line, risk to the collateral. The CFPB's debt collection resources explain what happens when a debt is not paid.
How to compare offers and choose
Use a consistent process when you compare a line of credit vs loan. The goal is to match the credit structure to the expense and your ability to repay.
- Define the need. Decide whether you need a one-time lump sum or ongoing access to funds.
- Check the total cost. Compare the APR, fees, and any penalties, not just the interest rate.
- Review the repayment terms. Confirm whether payments are fixed or variable and whether a balloon payment or maturity date applies.
- Consider the risk. Identify whether the debt is secured and what happens if you cannot pay.
- Review your credit. Check your credit reports for errors and understand how an application may affect your credit. The FTC explains your rights under the Fair Credit Reporting Act.
- Ask about all fees. Request a written list of closing costs, annual fees, and transaction fees before you sign.
- Compare multiple offers. Shopping can help you see differences in terms, but approval and pricing depend on the lender's review.
Before signing, confirm the amount, rate, fees, repayment schedule, and collateral requirements. The CFPB's loan tools and resources can help you ask better questions. You can also start with our loan basics library for related explainers.
