Truck finance rates are calculated by pricing risk. A lender starts from a base cost of funds, then adjusts for the truck itself, the age and strength of your ABN, your credit history, the documentation you provide and your deposit. Strong, asset-backed deals may see indicative pricing from around 6.55% p.a., subject to lender assessment, while riskier profiles are priced higher. Because each lender weighs these factors differently, Overdrive compares 80+ banks and non-bank lenders on one application to find where your deal is calculated most favourably.

It starts with the cost of funds
Every lender has a base cost of money, influenced by the broader interest rate environment. Your rate is that base plus a margin the lender adds to cover risk and make a return. When market rates move, the base shifts and pricing across the industry tends to follow. This is why truck finance rates are never truly fixed as an advertised number: the base moves over time, and the margin on top is set individually for your deal. Understanding this split helps explain why the same profile can be priced differently by different lenders on the same day.
The truck itself
The asset is central to the calculation because it is the lender's security. A newer, mainstream truck with a strong, predictable resale market is lower risk, so it attracts a thinner margin. An older truck, a highly specialised unit or one that is hard to resell carries more risk, so the margin widens. Age, kilometres, make and type all feed in. This is also why truck finance can be priced more sharply than an unsecured business loan: the lender can recover value from the asset if things go wrong, which reduces the risk it is pricing for.
Your business and credit profile
Lenders look closely at who is borrowing. A seasoned ABN with a trading history, clean personal and business credit, and evidence of steady income presents lower risk and earns a sharper margin. A newer ABN, past defaults or thin financials increase the perceived risk and lift the rate. The documentation you can supply matters here too: full financials generally support better pricing than a low-doc application, because the lender has more certainty about your capacity to repay. Each lender scores these elements on its own scale.
Deposit, term and structure
How the loan is structured also shapes the rate. A larger deposit reduces the amount at risk and can improve pricing, while a no-deposit structure may be available for eligible applicants but can push the rate up. The term, typically one to seven years, and any balloon or residual affect both the monthly repayment and the lender's exposure over time. These levers do not just change the percentage; they change the total cost, which is why the comparison rate and full-term cost are worth checking alongside the headline number.
Why comparing lenders matters
Because the calculation combines a moving base rate with a margin each lender sets in its own way, the same application can be priced very differently across the market. One funder may love your older truck while another prices it cautiously or declines. Lodging applications yourself to test this risks multiple credit enquiries. A broker instead matches your profile to the lenders most likely to calculate it favourably and gathers indicative pricing in one pass, so you see the range without damaging your credit file.
The rate you are offered is the sum of many moving parts, and the only way to see it clearly is to have your profile assessed against the market. Overdrive puts one dedicated broker across 80+ lenders on a single application, so you can understand how your deal is priced and where it lands most competitively.

Frequently Asked Questions
Is my truck finance rate fixed for the whole term?
It can be. Many truck finance facilities offer a fixed rate for the full term, so your repayment stays predictable. Variable options also exist. Which suits you depends on your cash flow and appetite for movement, and the choice affects both the rate and your total cost, subject to lender terms.
Does a bigger deposit lower my rate?
Often, yes. A larger deposit reduces the amount the lender has at risk, which can support sharper pricing. It also lowers the amount you finance and therefore your repayments. The exact effect varies by lender and profile, and no-deposit structures may still be available for eligible applicants, though they can cost more.
Why do two lenders quote different rates for the same truck?
Because each lender sets its own margin and weighs risk factors differently. One may favour older trucks or newer ABNs where another is cautious. The base cost of funds is broadly similar, but the risk margin on top varies, which is exactly why comparing several lenders tends to surface a better outcome.
Do low-doc applications always mean higher rates?
Generally, low-doc files are priced a little higher because the lender has less certainty about your income. That said, the gap varies by lender and the strength of the rest of your profile. A strong asset and clean credit can offset some of the low-doc premium, subject to lender assessment.
