June is the biggest month of the Australian new car year. Dealers have targets that pay manufacturer bonuses on units delivered by 30 June, business buyers want the tax deduction in this financial year, and the runout advertising writes itself. Into that urgency, dealerships sell finance, and the headline offers look unbeatable: 2.9 per cent, 1.9 per cent, sometimes zero, against broker-sourced secured car loans currently running roughly 7.5 to 9.5 per cent.
A 2.9 per cent loan does not beat an 8 per cent loan if it is attached to a more expensive car. That is the entire trick, and it has survived every regulatory intervention because it is not illegal. It is just arithmetic the buyer is never shown in one place.
Where the margin actually hides
- The price. Subsidised finance is almost always conditional on paying at or near full retail. The $3,000 to $5,000 discount a cash or broker-financed buyer negotiates on the same car quietly disappears. The "interest saving" was pre-paid in the drive-away price.
- The balloon. Low-rate offers are commonly structured with a residual of 30 to 50 per cent of the purchase price owed as a lump sum at the end of the term. The monthly repayment looks light because you are not actually paying the car off. At term end you refinance the balloon at whatever rates are then, hand the car back under strict condition rules, or find $20,000 in cash.
- The fees. Application fees of $400 to $900, origination fees, monthly account fees of $8 to $15, and end-of-term fees sit outside the headline rate. This is exactly what comparison rates exist to expose, and dealer finance comparison rates routinely run 2 to 4 percentage points above the advertised rate. The comparison rate is in the fine print, in grey, in font size 8.
- The term and eligibility fine print. The 2.9 per cent applies to specific runout stock, specific terms (often 36 months where the balloon maths flatters), and approved credit only. Walk in for the advertised car and rate, get "approved" for something slightly different.
The worked example: $48,000 ute, two paths
Path one, dealer offer: 2.9 per cent over 48 months on the full $48,000 drive-away with a 35 per cent balloon ($16,800), $695 application fee and $10 a month account fee. Repayments are about $700 a month, total repayments about $33,600 over the term, plus the $16,800 balloon, plus fees: all-in roughly $51,400, and you still needed to deal with the balloon at month 48.
Path two, broker pre-approval at 7.99 per cent and you negotiate like a cash buyer: the same ute at a realistic EOFY runout discount of $3,500 lands at $44,500. Financed over 48 months with no balloon and a $400 establishment fee, repayments are about $1,087 a month and the all-in cost is roughly $52,600. You own the car outright at month 48 with no $16,800 cliff.
The all-in totals are within about $1,200 of each other, except path one ends with a $16,800 debt still owing on a four-year-old ute and path two ends with a clear title. Re-run path one with the balloon refinanced for two more years at prevailing rates and it costs $3,000 to $4,500 more in total. The 2.9 per cent loan is the expensive one. It just doesn't look like it on a monthly payment comparison, which is the only comparison the dealership business manager will put in front of you.
Flex commissions died in 2018. The margin did not.
Until November 2018, dealers could set the customer's interest rate above the lender's base rate and keep the difference, which produced exactly the behaviour you would expect. ASIC banned flex commissions, and the ban worked as far as it went. What remains: dealers earn fixed origination commissions per contract, volume bonuses from their captive financier, and the structural ability to move margin between the metal, the trade-in, the aftermarket products and the finance. The four-square worksheet (price, trade, deposit, monthly payment) survives because it lets the business manager give you a win in whichever square you are watching while recovering it in the ones you are not.
The aftermarket add-ons deserve their own sentence: paint protection, tyre and rim insurance, gap insurance and extended warranties sold in the finance office routinely carry commissions of 40 per cent plus, and ASIC's past reviews of add-on insurance found claims ratios so poor that several products were effectively withdrawn. If you want gap cover, your insurer sells it for less.
The EOFY-specific advice
- Get finance pre-approved before you walk in. A broker pre-approval at 7.5 to 8.5 per cent secured costs nothing, holds for around 90 days, and converts you into a cash buyer at the negotiating table. The rate gap between broker-sourced and average dealer finance has been running 1.8 to 2.6 percentage points all year.
- Negotiate the drive-away price first, in writing, before the word finance is mentioned. If the price moves when you decline their finance, you have just measured the subsidy.
- If you are a business buyer chasing the instant asset write-off, remember the permanent threshold is $20,000 per asset for businesses under $10 million turnover, so a $48,000 ute is depreciated under the general rules instead. The EOFY tax urgency the dealership is selling you may not match your actual tax outcome. Five minutes with your accountant beats a banner.
- Decline every product in the finance office on the day. Gap insurance, tyre and rim, paint protection and extended warranties can all be bought later, calmly, from anyone, if they make sense at all.
Disclosure: Your Finance Guide partners with Australian Lending and Investment Centre (ALG) ACL 505575 for broker matching. ALG receives commissions from lenders on settled vehicle finance, which is the same structural conflict dealer finance has; the difference we would point to is panel breadth and the absence of any margin in the vehicle price. Worked examples are indicative, rounded, and depend on credit profile and lender. Rate ranges are from published lender rate cards as at early June 2026.
