Quick Picks
Lowest advertised starting rate: Westpac Car Loan, at 6.49% p.a. for eligible green vehicles.
Best for transparent major-bank terms: NAB Secured Car Loan, with published rates from 6.74% to 13.54% and no exit fees.
Best for dealership convenience: Toyota Finance Personal Car Loan.
Best for a fast digital quote: Plenti Secured Car Loan.
Car finance is a route map, not a single price tag. The interest rate matters, but so do the comparison rate, establishment fee, vehicle rules, repayment term and any balloon payment. The figures below are drawn from the supplied lender information and linked provider pages; confirm the live offer before applying.
Rates and terms shown are representative. Your actual rate depends on your credit profile and circumstances. This is not financial advice — always read the lender's terms before applying.
Start with the rate, then check the route
The headline gap is narrow: Westpac begins at 6.49% p.a. for eligible green vehicles, NAB at 6.74%, CommBank at 6.79%, and Plenti at 7.49% in the supplied comparison data. That spread looks small until you borrow A$40,000 over five years. A rate difference of roughly one percentage point can add hundreds of dollars in interest, before fees.
The less obvious issue is that the cheapest-looking number may not be the number you receive. Westpac publishes a 7.90% comparison rate in the supplied page content, while Plenti lists a 9.78% comparison rate against its quoted 7.99% page figure. Comparison rates fold in certain fees and show why the advertised rate alone is incomplete. Toyota Finance is different again: its page promotes personalised fixed-rate finance, but the supplied information does not provide a public starting rate, so it is harder to price before speaking with a dealer.
EV incentives also change the ranking. Westpac, NAB and CommBank each advertise a green-vehicle benefit in the supplied data, but eligibility depends on the vehicle and lender rules. A petrol-car buyer should not assume the lowest EV rate applies to them.
Major-bank loans with published numbers
NAB, Westpac and CommBank all use the secured-loan model: the vehicle supports the loan, and the lender can impose age or eligibility rules. That structure generally produces lower pricing than an unsecured loan, but it also means the car is collateral. Read the security terms before treating a low rate as a free saving.
Westpac Car Loan
Westpac has the sharpest advertised entry point in this group at 6.49% p.a. for eligible green vehicles, with a 7.90% comparison rate shown in the supplied page content. The loan can run for up to seven years, has no early repayment fees, and can be applied for online. The downside is structural: it is secured, an establishment fee applies, and used vehicles must be under seven years old. Best for an Australian borrower buying an eligible low-emission vehicle who wants a big-four bank and plans to repay early without an exit charge.
Westpac wins on the visible starting rate, but the comparison rate is the detail that keeps the result honest. NAB gives up a small amount on the entry rate in exchange for a more clearly published rate band and no exit fee. That difference matters if you value predictable terms more than the lowest possible headline.
NAB Secured Car Loan
NAB publishes a fixed-rate range from 6.74% to 13.54%, which gives borrowers more context than a single promotional number. It also allows borrowing up to A$100,000, includes no exit fees, and advertises a 0.75% discount for eligible EVs. The secured product is sole-borrower only, requires monthly direct debit, and is powered by Plenti according to the supplied page content, so the NAB brand does not mean every part of the application is handled like a traditional branch loan. Best for a single borrower who wants a major-bank route, a large borrowing limit and no exit fee.
NAB Secured Car Loan
AutoFor the live rate bands and eligibility details, check Westpac's car-loan page and NAB's secured car-loan page. The lender pages should take priority over comparison summaries because vehicle eligibility and promotional pricing can change.
Both bank options are more restrictive than a generic personal loan because the car secures the debt. That can reduce the rate, but it narrows your choice of vehicle and leaves less room for an older used car. CommBank follows the same secured structure while putting more emphasis on fast online decisions and green-car pricing.
Green-car discounts and everyday bank access
EV and plug-in-hybrid discounts are now a meaningful pricing lever in this comparison. The advertised difference may look modest, but a discount applied across a multi-year loan can be worth more than a small account perk. Check the exact vehicle definition, because “green” pricing is not automatically available for every hybrid or efficient petrol model.
CommBank Secured Car Loan
CommBank quotes rates from 6.79% p.a. in the supplied data and 6.49% p.a. for eligible electric and plug-in-hybrid vehicles. The fixed rate supports stable repayments, terms extend up to seven years, and online applications can produce fast decisions. The pricing is not fee-free: an establishment fee and monthly account fee apply, while the vehicle remains collateral. Compared with NAB, CommBank has a slightly higher standard starting rate but a similarly attractive green rate; it suits a buyer who already uses the bank and wants online processing rather than dealer-arranged finance.
CommBank is easier to place than its rate alone suggests. For a standard petrol vehicle, NAB's 6.74% starting point is marginally lower; for an eligible EV or plug-in hybrid, CommBank's 6.49% figure narrows or reverses that gap. The monthly account fee means you should compare total repayments, not just the rate printed near the application button. See CommBank's car-loan page for the current fee schedule and vehicle criteria.
That leaves the digital lender. Plenti does not have the branch network or household-bank relationship of the three major banks, but its quote process and higher borrowing ceiling appeal to a different borrower.
Plenti Secured Car Loan
Plenti's online flow promises a personalised rate in as little as 60 seconds, and the supplied data lists borrowing up to A$100,000 with three- to seven-year terms. Its quoted starting rate is 7.49% in the comparison record, while the page content shows 7.99% interest and a 9.78% comparison rate, so applicants should verify the live figure before relying on the ranking. A soft quote without credit-score impact is useful for early shopping, but stronger applicants receive the best pricing and vehicle-age rules vary. Best for a borrower who needs a larger secured loan and wants to compare a digital quote before visiting a dealer or bank.
Plenti's real advantage is the early-stage quote, not the headline rate. Its comparison rate sits materially above the advertised figure in the supplied page content, so a borrower focused on total cost may prefer NAB or Westpac if the approved rates are close. The A$100,000 cap and fast quote still make Plenti useful for a higher-priced vehicle or a buyer who wants an independent benchmark before negotiating with a dealer.
For the current quote process and published figures, review Plenti's car-loan page. A quote is not an approval, and the final rate depends on the applicant and vehicle.
The major-bank and fintech routes all require attention to secured-loan conditions. Toyota's dealer-integrated model changes the decision: convenience becomes part of the product, but the price is harder to compare upfront.
Dealer-arranged finance and the balloon-payment question
Toyota Finance is the outlier because the process is built around the Toyota dealer network rather than a publicly displayed rate table. The lender offers a customised fixed-rate personal car loan, dealership finance and a balloon-payment option. Those features can make the purchase feel simpler, but simplicity is not the same as low total cost.
Toyota Finance Personal Car Loan
Toyota Finance is built for the buyer who wants finance arranged beside the car purchase. The fixed rate supports payment certainty, the loan can be customised, and a balloon payment may reduce scheduled instalments. The missing piece is a public rate in the supplied information, so you cannot rank its cost against Westpac's 6.49% green rate or NAB's published band without a personalised quote. The balloon also increases the amount due later and can raise total cost. Best for a Toyota buyer who values dealer convenience, understands the final balloon amount and is prepared to compare the written offer against an outside lender.
The balloon option deserves a calculation, not a sales conversation. Lower monthly repayments can hide a large final obligation, and the vehicle's future value may not cover it. Ask for the total amount payable, the balloon amount, every fee and the rate without the balloon structure. Toyota's official personal fixed-rate loan page explains the product route, but the dealer's written quote is what determines the actual cost.
I'd choose Toyota Finance only after comparing that quote with at least one bank or fintech offer. The convenience premium may be acceptable, but it should be visible in dollars rather than hidden inside a lower monthly repayment.
Comparison table: which route fits the borrower?
| Lender | Advertised rate in supplied data | Term or limit | Main cost issue | Best for |
|---|---|---|---|---|
| Westpac | From 6.49% p.a. for eligible green vehicles; 7.90% comparison rate shown | Up to 7 years | Establishment fee; used cars under 7 years | Green-car buyers wanting no early repayment fee |
| NAB | 6.74%–13.54% p.a. | Up to A$100,000 | Secured, sole-borrower product; direct debit required | Borrowers wanting public rate bands and no exit fee |
| CommBank | From 6.79% p.a.; 6.49% for eligible EVs and plug-in hybrids | Up to 7 years | Establishment fee and monthly account fee | Existing bank customers buying eligible green vehicles |
| Plenti | From 7.49% in comparison record; page shows 7.99% and 9.78% comparison rate | A$100,000; 3–7 years | Higher comparison rate; vehicle rules vary | Borrowers wanting a fast digital quote or larger loan |
| Toyota Finance | Personalised fixed rate; no public rate supplied | Customised; balloon available | Balloon can increase total cost; Toyota network focus | Toyota buyers who prioritise dealer-arranged finance |
Final route map
Westpac is the first quote to test if you are buying an eligible green vehicle and want no early repayment fee. NAB is the cleaner comparison point for a single borrower who wants a published rate band, up to A$100,000 and no exit fee. CommBank makes sense for an existing customer buying an eligible EV or plug-in hybrid, but include its monthly account fee in the total.
Plenti earns a place on the shortlist for fast digital rate discovery and larger secured borrowing, not because its comparison rate is the lowest. Toyota Finance suits a Toyota buyer who values dealer convenience and fixed repayments, provided the balloon and total repayment are fully understood.
Before signing, compare the same loan amount and term across written offers, then check the comparison rate, establishment fee, account fee, early repayment rules and final balloon.
