Loan Calculator

Need to borrow money? A personal loan isn’t your only option. A line of credit can get you funds too, but how you borrow, repay, and pay interest works quite differently.

Broadly: a personal loan hands you a set amount to pay off over an agreed term. A line of credit gives you an approved limit to dip into whenever needed. Which suits you depends on what you’re borrowing for, how much you need, and how predictable your spending is.

In this guide, we’ll break down how each option works, when one makes more sense than the other, and what to compare before you apply.

What’s the Difference?

Think fixed borrowing versus flexible access to funds.

A personal loan gives you a specific amount upfront, with regular repayments over a set period, commonly one to seven years. People use them for a car, a holiday, renovations, or debt consolidation, depending on the lender.

A line of credit is more like a pool of money you draw on as needed, within an approved limit. Interest is generally charged only on what you’ve drawn. That’s useful flexibility, but it can also make it easy to keep borrowing without a clear repayment plan.

How Each One Works?

Personal Loan: It gives you a fixed sum upfront, repaid with interest and fees. Borrow $20,000 for a major purchase and you might agree to a five-year term, with repayments depending on the rate, term, and fees.

Fixed rates stay predictable; variable rates shift with the lender. Compare the interest rate, comparison rate, fees, and conditions together, rather than choosing on the advertised rate alone.

Line of Credit: It gives you access to a limit rather than a lump sum. Approved for $10,000, you might use $2,000 to start and draw more later without a separate application, handy when you’re not sure exactly when or how much you’ll need.

The trade-off: debt can be harder to track. Keep drawing without paying it back, and the balance can hang around longer and cost more in interest. It also varies by lender, so check the specific terms.

Which Fits Your Situation?

For a large, one-off expense, say $25,000 for a renovation or car, a personal loan usually makes more sense: the full amount upfront and a fixed schedule give a clearer picture of what you owe and when it’ll be gone.

It’s a common path too. According to the Australian Bureau of Statistics, new personal fixed-term loan commitments hit $9.7 billion in June 2026, up 7.1% on June 2025.

If your needs aren’t predictable, say a few expenses over the year with no clear timing or cost, a line of credit gives you room to move without a new application each time. Flexible doesn’t mean cheaper, though.

If you’ll use most of the limit for a long stretch, weigh the rate, fees, and terms against what a personal loan would cost instead.

Not sure which fits? Run the numbers through our personal loan calculator. Seeing repayments side by side usually makes the decision clearer than reading about it in the abstract.

Interest and Fees

With a personal loan, repayments come from the amount, rate, and term. With a line of credit, you typically pay interest only on what you’ve drawn, but account, annual, or other fees can apply on top.

That doesn’t automatically make it cheaper. Real cost depends on how much you borrow, how long it’s outstanding, and the fees involved. Worth checking application, ongoing, missed-payment, and early-repayment fees, not just the headline rate.


“The mistake we see most often isn’t picking the wrong product, it’s underestimating how long a balance can sit there once it’s flexible to draw on. A line of credit that stays half-used for two years can end up costing more than a personal loan you’d have paid off in one. Before you apply, work out roughly how long you’d realistically take to clear the balance, not just what the repayments look like in month one.”

What to Compare Before Applying?

Don’t stop at the interest rate. Check these before you commit:

  • Comparison rate: bundles interest with standard fees, though it’s based on assumptions that might not match your situation
  • Fees: establishment, ongoing, annual, late-payment, and early-repayment
  • Repayment structure: how it fits against your budget
  • Loan or credit limit: whether it actually matches your needs
  • Flexibility: a defined end date versus ongoing access

Which Should You Choose?

A personal loan probably fits if you: know exactly how much you need, have a specific one-off expense, want predictable repayments, and want a defined end date.

A line of credit might fit if you: have needs that shift over time, don’t need the full amount right away, want ongoing access to funds, and already have a plan for managing and repaying the balance.

What’s actually available depends on the lender, your circumstances, and eligibility.
