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

Borrowing money should be simple. But walk into any comparison site and you're suddenly looking at interest rates, draw periods, revolving credit facilities, and it all starts to feel a bit much.

Two of the most common borrowing options Australians turn to are personal loans and lines of credit. They might seem interchangeable at first glance, but they work quite differently. Choosing the wrong one could cost you more than you expect, or leave you without the flexibility you actually need.

So let's break it down in plain English.

What Is a Personal Loan?

A personal loan gives you a lump sum of money upfront, which you then repay in fixed instalments over a set term, usually between one and seven years.

The big appeal? Predictability. You know exactly how much you borrowed, exactly what your repayments are, and exactly when the loan ends. No surprises.

Personal loans can be secured (backed by an asset like a car) or unsecured (no collateral required). Unsecured personal loans are more common for everyday expenses, though they tend to come with slightly higher interest rates to offset the lender's risk.

They're a solid fit for one-off, defined expenses, including things like:

• A car purchase or repairs
• Medical or dental bills
• A wedding or holiday
• Debt consolidation

The downside is that once the funds are in your account, that's it. If you need more money down the track, you'd need to apply for a new loan.

What Is a Line of Credit?

A line of credit works more like a credit card than a traditional loan. Instead of receiving a lump sum, you're approved for a set credit limit and can draw down what you need, when you need it.

Here's what makes it different: you only pay interest on the amount you've actually used, not on your full credit limit. And as you repay what you've borrowed, that credit becomes available to use again.

It's a revolving facility, which means it stays open as long as you're in good standing with the lender. Rates are typically variable, and there's often no fixed end date.

Lines of credit are generally used for:

• Home renovations with unpredictable costs
• Ongoing business expenses
• Managing irregular income or cash flow gaps
• Emergencies where the total cost is hard to predict upfront

One thing worth knowing: the interest rate on a line of credit is often slightly higher than on an unsecured personal loan. You're paying for the flexibility.

Personal Loan vs Line of Credit: Key Differences

Feature	Personal Loan	Line of Credit
Structure	Fixed lump sum upfront	Revolving credit limit
Interest	Fixed rate on full loan amount	Variable rate on drawn amount only
Repayments	Fixed schedule (weekly/fortnightly/monthly)	Flexible minimums
Loan term	Set term (1–7 years)	No fixed end date
Best for	One-off, defined expenses	Ongoing or variable needs
Discipline required	Low: repayments are automatic	High: easy to overborrow

Pros and Cons of Each

Personal Loan

Pros:

• Predictable repayments make budgeting straightforward
• Fixed interest rate means you're protected from rate rises
• Clear end date: you know when you'll be debt-free
• Often lower interest rates than lines of credit

Cons:

• Less flexible: you can't access extra funds without reapplying
• Interest accrues on the full loan amount from day one, even if you don't use all the funds immediately
• May not suit expenses where the total cost is uncertain

Line of Credit

Pros:

• Flexible: draw down only what you need, when you need it
• You only pay interest on what you actually use
• Can be reused as you repay, making it handy for ongoing costs

Cons:

• Variable rates mean repayments can change over time
• No fixed end date can mean the debt lingers longer than expected
• The flexibility can make it tempting to overborrow
• Typically higher interest rates than personal loans

Which One Is Right for You?

Here's a simple way to think about it.

Choose a personal loan if:

• You know exactly how much you need
• You want predictable, fixed repayments
• You're covering a one-off expense like a car, wedding, or medical bill
• You want the discipline of a clear repayment timeline

Choose a line of credit if:

• Your costs are variable or hard to predict upfront
• You need flexibility to draw funds over time
• You have the financial discipline to manage a revolving facility without overspending
• You're covering something ongoing, like a renovation with unexpected costs

To be honest, most everyday Australians are better served by a personal loan. The structure keeps things simple, and knowing your exact repayment schedule makes budgeting a lot easier. If you're unsure where to start, our step-by-step guide to getting a personal loan walks you through the process.
