Line of Credit vs. Personal Loan: Key Differences

You need to borrow money, and two options keep showing up: a personal loan and a line of credit. They sound similar, and both can put cash in your hands. But they work in very different ways, and picking the wrong one can cost you more than it should.

The short version: a personal loan hands you a fixed lump sum that you repay in equal installments. A line of credit gives you a credit limit you can draw from again and again, paying interest only on what you actually use. Below, we break down how each one works, what it costs, and when each tends to make sense.

How a personal loan works

A personal loan is an installment loan. You apply for a set amount, say $10,000, and if approved you get the full sum at once, usually deposited in your bank account. From there, you repay it over a fixed term, often 2 to 7 years, in equal monthly payments.

Most personal loans carry a fixed interest rate. That means your rate, your payment, and your payoff date are all locked in from day one. You know exactly what you will pay each month and when the loan ends. Many lenders also charge an origination fee, often 1% to 8% of the loan amount, which can be deducted from your funds upfront. It helps to understand the difference between your interest rate and APR, since the APR folds those fees into one number you can compare across lenders.

Personal loans are typically unsecured, meaning no collateral is required. Approval and your rate depend heavily on your credit score, income, and debt load. If you want to size up your options before applying, a marketplace like Upstart lets you check your personal loan rate with a soft pull that will not hurt your score, which is a low-risk way to see the lump-sum route in real numbers.

How a line of credit works

A personal line of credit is revolving credit, closer in spirit to a credit card than to a loan. The lender approves you for a maximum limit, for example $15,000, and you can draw from it as needed. You only pay interest on the amount you have drawn, not the full limit.

As you repay what you borrowed, that money becomes available again. This makes a line of credit useful when you are not sure exactly how much you will need or when you will need it.

Most lines of credit carry a variable interest rate, which can rise or fall over time. They also tend to have two phases: a draw period when you can borrow and make smaller payments, followed by a repayment period when you can no longer draw and must pay down the balance.

Personal loan vs. line of credit: side by side

What each one costs

With a personal loan, the cost is predictable. A fixed APR means you can calculate your total interest before you sign. The tradeoff is that if you borrow $10,000 but only needed $6,000, you still pay interest on the full $10,000.

With a line of credit, you may pay less interest if you borrow small amounts and repay quickly, since interest applies only to your outstanding balance. But the variable rate adds uncertainty. If rates climb, your cost climbs too. Some lines also charge annual or maintenance fees whether or not you use them.

As always, APRs vary by creditworthiness, and the lowest advertised rates usually go to borrowers with strong credit. Terms and conditions apply with any lender. Because both structures are easy to compare side by side, MoneyLion can surface loan and line offers from multiple lenders in one place, which helps you see which structure actually wins on cost for your situation.

Secured vs. unsecured versions

Both products come in secured and unsecured forms. An unsecured loan or line relies on your credit profile alone. A secured version is backed by collateral, such as a savings account, certificate of deposit, or home equity. For example, using your car as collateral for a personal loan can lower your rate, but it also puts the vehicle at risk if you fall behind.

A home equity line of credit, or HELOC, is a common secured line that uses your house as collateral. If you are weighing that route, our breakdown of a HELOC vs. a personal loan walks through the tradeoffs. Secured options can carry lower rates because the lender has less risk, but you may lose the collateral if you cannot repay. That is a serious tradeoff to weigh carefully.

How each affects your credit

Applying for either one usually triggers a hard inquiry, which can dip your score by a few points temporarily. After that, the effects differ.

A personal loan adds to your credit mix as an installment account, and a balance that shrinks over time can look favorable. A line of credit is revolving, so your utilization, the share of your limit you are using, matters. Carrying a high balance against your limit can weigh on your score, much like a maxed-out credit card.

Before you apply for either, it helps to know where your credit stands. A monitoring service like Creditship can show your score and what is driving it, so you can pick the product and lender that fit your profile and avoid an application you are unlikely to win.

When each one makes sense

A personal loan tends to fit a one-time expense with a known cost: consolidating debt, paying for a wedding, or covering a medical bill. You want the full amount now and the discipline of a fixed payoff schedule. If you are still on the fence, our honest look at whether personal loans are bad weighs the pros and cons before you commit.

A line of credit tends to fit ongoing or uncertain needs: a home renovation that unfolds in stages, irregular income, or an emergency cushion you may or may not tap. You want flexibility and only want to pay for what you use.

Checking a few quotes before committing helps you see which structure, and which rate, actually wins for your situation.

Frequently Asked Questions

Is a personal loan or line of credit cheaper?

It depends on how you borrow. A personal loan with a fixed rate is cheaper when you need a known lump sum and want a predictable payment. A line of credit can cost less if you borrow small amounts and repay quickly, since you pay interest only on what you use, but a variable rate adds risk.

Can I have both a personal loan and a line of credit?

Yes, many people carry both, as long as they qualify and can manage the payments. Lenders look at your total debt and income when you apply, so existing obligations may affect approval or your rate. Borrow only what you can comfortably repay.

Does a line of credit hurt your credit score more than a loan?

Not inherently, but a line of credit is revolving, so a high balance against your limit can raise your utilization and weigh on your score. A personal loan is an installment account, and a shrinking balance over time can look favorable. Responsible use of either supports your credit.

What credit score do I need for a personal loan or line of credit?

Many lenders look for a score in the mid-600s or higher for the best terms, though some lenders consider applicants with lower scores. Your income, debt-to-income ratio, and overall history also matter. APRs vary by creditworthiness, so checking prequalified rates first gives you a clearer picture.
