What Is a Line of Credit (LOC)?
Let me explain what a line of credit, or LOC, really is. It's a preset borrowing limit that banks and financial institutions offer to their personal and business customers. You can use this line at any time until you hit that limit, which the issuer sets based on your creditworthiness. Once you repay what you've borrowed, you can borrow again if it's an open line of credit. You access the funds whenever you need them, as long as you stay under the maximum amount or credit limit outlined in the agreement.
Understanding Lines of Credit (LOCs)
You should know that a line of credit is a credit product banks provide to both personal customers and business clients. Just like other credit options, you have to qualify for approval. You might apply directly or get pre-approved, and the limit depends on your creditworthiness. Every LOC has a set amount you can borrow as needed, pay back, and borrow again. The lender sets the interest, payment sizes, and other rules. Some let you write checks, others give you a debit card to tap into the credit. They can be secured or unsecured—secured ones have lower rates because they're backed by collateral, while unsecured ones come with higher rates.
The big advantage here is the flexibility. You request what you need, but you don't have to use it all. You only pay interest on what you draw, not the whole line. You can adjust repayments based on your budget or cash flow—pay it all off at once or stick to minimum monthly payments. Common types include personal, business, and home equity lines of credit, which I'll cover more below.
Unsecured vs. Secured Lines of Credit (LOCs)
Most LOCs are unsecured, meaning you don't pledge any collateral to back them. A key exception is the home equity line of credit, or HELOC, secured by your home's equity. From the lender's side, secured LOCs are preferable because they can recover funds if you don't pay. For you as a borrower or business owner, secured ones often mean higher credit limits and lower interest rates than unsecured options. Unsecured LOCs are tougher to get and usually require a strong credit score.
Lenders offset the risk in unsecured LOCs by capping how much you can borrow and charging higher rates—that's why credit card APRs are so high. Credit cards are essentially unsecured LOCs, with the limit being what you can charge. If you miss payments, there's no asset for the issuer to seize.
Revolving vs. Non-Revolving Lines of Credit (LOCs)
Consider an LOC as a revolving account, or open-end credit, where you spend, repay, and spend again in an ongoing cycle. This differs from installment loans like mortgages or car loans, where you borrow a fixed amount and pay it back in equal installments until it's done—you can't reuse the funds without a new application.
Non-revolving LOCs work similarly to revolving ones: you get a credit limit, use funds for various purposes, pay interest, and make payments anytime. But once you pay it off fully, the account closes and can't be reused. For instance, banks might offer personal LOCs as overdraft protection on checking accounts—if you overdraw, it covers you, but you must repay with interest.
Types of Lines of Credit (LOCs)
LOCs vary, falling into secured or unsecured categories, each with unique features. A personal LOC gives you access to unsecured funds you can borrow and repay repeatedly. It typically requires no defaults in your credit history, a score of 670 or higher, and steady income. Savings or collateral like stocks or CDs help, though not always needed. Use it for emergencies, weddings, travel, or irregular income smoothing.
Other Common Types
- Home Equity Line of Credit (HELOC): Secured by your home's value minus what's owed, often up to 75-80% of that equity. It has a draw period, usually 10 years, for borrowing and repaying, followed by full repayment or extension. Expect closing costs like appraisals, and note that interest is deductible only for home improvements under current tax laws.
- Business Line of Credit: Businesses borrow as needed instead of fixed loans. The lender assesses your business's value, profitability, and risk to set the limit, which can be secured or unsecured with variable rates.
- Demand Line of Credit: Can be secured or unsecured, but rarely used. The lender can demand repayment anytime, with payments possibly interest-only or including principal.
- Securities-Backed Line of Credit (SBLOC): Secured by your securities, allowing borrowing 50-95% of their value. It's non-purpose, so no using funds for securities trading, but okay for other expenses. Requires monthly interest payments, and the lender can call it if your portfolio value drops.
Limitations of Lines of Credit (LOC)
While the main benefit is borrowing only what you need without interest on the full amount, watch out for issues. Unsecured LOCs have higher rates and stricter credit requirements. Rates are usually variable and differ by lender. They lack the protections credit cards have, so late payments or exceeding limits can lead to harsh penalties. An open LOC might tempt overspending, causing payment problems, and misuse can damage your credit score—using over 30% of the limit often drops it.
The Bottom Line
In summary, consumers and businesses use credit for big purchases, operations, or growth, and an LOC is one way to do that. You must qualify and get approved by a lender first. You can draw on it multiple times up to the limit, as long as you make minimum payments.
