Car Finance: Loan vs Novated Lease vs Saving Up. Which Is Cheapest?

Buying a car in Australia usually starts with a very noble sentence: "I'll be sensible about this." Then somehow you are three tabs deep comparing repayments on a mid-spec SUV you definitely did not plan to fall in love with.

The real question is not just "Can I afford the repayment?" It is "Which path leaves me best off overall?" For most people the three main options are:

• Car loan if you need the car now and want a straightforward setup
• Novated lease if your employer offers salary packaging and the tax maths works
• Saving up and paying cash if you can wait and want to avoid interest altogether

Each can be the smartest option in the right situation. Each can also be an expensive own goal if you only look at the weekly repayment and ignore the rest of the bill.

Option 1: Car loan

A car loan is the simplest option. You borrow the purchase amount, repay it over a set term, and own the car at the end. No salary packaging, no tax tricks, no explaining residual values to your confused uncle at lunch.

The upside is simplicity:

• predictable repayments
• easy to compare lenders
• works whether you are PAYG, self-employed, or changing jobs
• more control over the car and finance structure

The downside is cost. You are paying interest, establishment fees in some cases, and often more than you think if the term stretches out to five or seven years.

For example, borrowing $45,000 over 5 years at 7.5% means repayments of roughly $901 a month. Over the full term, you repay about $54,000. That extra nine grand is the price of not waiting.

If you want to sanity-check different rates and terms, the Loan Repayment Calculator is useful for seeing how much the monthly number changes when the rate or term moves. Small differences matter more than dealerships would like you to notice.

Option 2: Novated lease

A novated lease can look magic because the payments come out of your salary package and, in the right setup, the after-tax cost can be lower than a standard loan.

That matters most for eligible EVs, where Fringe Benefits Tax concessions can make the numbers genuinely attractive. For regular petrol cars, the benefit is usually smaller and sometimes disappears once fees, interest and bundled running costs are included.

What makes novated leases appealing:

• payments are taken from salary packaging arrangements
• running costs can be bundled in
• tax savings may reduce the true cost
• EV concessions can materially improve the deal

What catches people out:

• you need an employer that offers salary packaging
• quotes can be harder to compare than a plain loan
• there may be admin fees and lease management fees
• a residual payment is still waiting for you at the end
• changing jobs can make the setup more annoying than expected

That last point is worth underlining. A novated lease is not free money with wheels attached. It is still a finance product. If the only reason it looks cheap is because the quote has hidden half the moving parts, you have not found a bargain. You have found marketing.

Option 3: Saving up and paying cash

Saving up is usually the cheapest option on paper because you avoid interest completely. If you buy a $30,000 car with cash, the cost is... well, $30,000. Refreshing stuff.

But paying cash has a trade-off. The cost is not only financial. It is also about timing.

If your current car is unreliable, expensive to repair, or about one school pickup away from a public breakdown with full dramatic effect, waiting two more years might not be realistic. In that case, financing can still be sensible because it solves a real problem now.

Saving up tends to work best when:

• your current car is still usable
• you can delay the upgrade
• you want a cheaper used car rather than a brand new one
• you value flexibility more than convenience

It also forces a useful reality check. People who save for a car often end up buying less car than they planned, which sounds boring right up until they realise they also kept their weekends and bank balance.

A rough comparison

Let's compare three simplified examples for someone looking at a $45,000 car in 2026:

The point is not that one option always wins. It is that the headline repayment can be the least useful number in the room. Total cost, tax effect, flexibility and timing matter more.

How to decide which option is best for you

Choose a car loan if...

• you need the car soon
• you want a simple comparison between lenders
• your employer does not offer salary packaging
• you do not want the admin complexity of a novated lease

Choose a novated lease if...

• your employer offers salary packaging
• you are considering an EV or a setup with genuine tax advantages
• you are comfortable comparing quotes carefully
• you expect job stability during the lease term

Choose saving up if...

• you can wait
• you want the lowest total cost
• you are happy buying a cheaper or used car
• you would rather keep debt out of the picture entirely

The mistake to avoid

The biggest mistake is shopping by repayment instead of shopping by total cost.

A dealership can always make the monthly repayment look friendlier by stretching the term, adding a balloon, or bundling in extras you did not ask for. That does not make the car cheaper. It just makes the pain arrive in a more polite format.

Before you sign anything, check:

• the total amount repaid over the full term
• all upfront and ongoing fees
• whether there is a residual or balloon payment
• what happens if you sell the car early or change jobs
• whether you are comparing like for like across all options

Bottom line

If you only care about the cheapest path in pure dollars, saving up and paying cash usually wins.

If you need the car now and want the cleanest, easiest structure, a car loan is usually the practical middle ground.

If you have salary packaging and the tax settings suit you, especially with an EV, a novated lease can absolutely come out ahead. But you need to check the full quote, not just the shiny savings headline.

Cars are expensive enough already. No need to accidentally finance the confusion as well.
