Short on Cash? When to Use a Line of Credit vs. an Installment Loan

Life has a way of throwing curveballs. This might mean unexpected bills, car trouble, or late paychecks that can leave anyone scrambling. In fact, 50% of Americans say they’re stressed about meeting their family’s basic needs, and 56% worry about job stability and workload. 

When money is tight, two common borrowing options are a line of credit and an installment loan. Each has its place, but knowing which one to use can make a big difference. In this article, we’ll break down the differences and help you decide which option makes the most sense for your situation.

What’s the Difference Between an Installment Loan and a Line of Credit?

An installment loan is a lump sum of money you borrow and repay over a set period through fixed, regular payments. A line of credit gives you access to a set borrowing limit that you can draw from as needed, repaying and borrowing again over time.

Structurally, installment loans are fixed—you know exactly what you owe and when it’s due. Lines of credit are revolving, meaning you can reuse available funds as you repay them, similar to a credit card.

While we’ve covered the basics in a previous article, this guide takes a more practical approach. Instead of repeating definitions, we’ll walk through two real-life situations to help you better understand when each borrowing option makes the most sense.

Real-Life Scenario #1: The Freelance Worker

• Need: Irregular income


• Best fit: Line of credit

Freelancers and gig workers often experience income that varies from month to month. One month might be packed with work, while the next is quiet. In this case, a line of credit can offer valuable flexibility. You can borrow only what you need to cover bills, equipment, or even quarterly tax payments—and pay interest only on the amount used. As you repay, the available credit resets, allowing you to borrow again without reapplying.

This setup is especially helpful during dry spells or when waiting on client payments. However, this freedom requires financial discipline. Without careful tracking, it’s easy to borrow more than intended and end up with a balance that’s hard to pay off. For freelancers who can stick to a budget, a line of credit is a smart way to stay afloat between paychecks without dipping into savings.

Real-Life Scenario #2: One-Time Medical Procedure

• Need: Known, large one-time cost


• Best fit: Installment loan

Let’s say you’ve scheduled a medical procedure that costs $2,000. It’s a single, necessary expense, and you know the total amount upfront. In this case, an installment loan is likely the better choice. You’ll receive a lump sum and repay it over time in equal monthly payments, helping you manage your budget without surprises.

The predictability of an installment loan is one of its biggest advantages. You know exactly how much you owe and when it will be paid off. There’s no option, or temptation, to keep borrowing, which helps keep your finances in check.

The tradeoff? If another expense comes up while you’re still repaying the first loan, you’ll need to apply for a new one. But for one-time, high-cost needs, installment loans offer structure and peace of mind.

Budgeting and Repayment Considerations

Any time you borrow money from a lender, you will need to pay it back. This means you must prepare for those payments as part of your budget. 

With installment loans, the key is to plan for consistent monthly payments. Because the amount and due dates are fixed, it’s easier to build repayment into your regular budget. Using tools like a payment calendar or auto-pay reminders can help you stay on track.

For a line of credit, tracking how much you borrow is critical. It’s easy to lose sight of small withdrawals that add up over time. Budgeting apps can help you monitor your usage and avoid borrowing more than you can afford to repay.

Missing payments, on either loan type, can hurt your credit score and lead to late fees. Sticking to a repayment plan not only avoids extra costs but also helps build a positive credit history.

Credit Score Impact: What Borrowers Should Know

Let’s talk a bit about the impact on your credit score. You may already know that there are five factors that go into your score, which range from 300 to 850. These things include your payment history, your credit utilization, your credit mix, the length of your credit history, and new credit. And the biggest factor? Yep, you guessed it. It’s that payment history.

A line of credit can affect your credit utilization ratio, which is the amount you’ve borrowed compared to your credit limit. Maxing it out can lower your score. In contrast, installment loans can help build credit by showing consistent payments on a fixed balance.

Installment loans also tend to be easier to qualify for, with many lenders considering scores around 580 or higher. Before applying, check your score—it’s a good guide for which option may be more accessible.

Can You Use Both? Strategic Borrowing Tips

Yes. You can use both an installment loan and a line of credit, and in some cases, it might be the smartest move. Each serves a different purpose, and when used thoughtfully, they can complement one another.

A line of credit is ideal for ongoing or smaller, unpredictable expenses like car maintenance, covering a short paycheck, or replacing a broken appliance. You can borrow as needed and only pay interest on what you use.

An installment loan, on the other hand, is better suited for larger, planned expenses—like paying off medical bills or making necessary home repairs—where you know the exact amount and want a clear repayment schedule.

Having both options available gives you flexibility while helping you avoid financial strain. The key is to plan ahead, borrow only what you need, and make repayment part of your regular budget. Strategic use can help you stay in control.

Choosing the Right Fit for Your Financial Needs

Whether you’re managing unpredictable income or facing a one-time expense, understanding how lines of credit and installment loans work can help you borrow more confidently. Each option has its strengths. The right choice for you simply depends on what fits your situation.
