Fixed truck finance rates lock in the same repayment for your whole loan term, while variable rates can move up or down with the market. The right choice depends on how much certainty your business needs versus how much flexibility you want around extra repayments or early payout.
Fixed Rates: Predictable Repayments for the Life of the Loan
A fixed rate locks in your interest rate for the full term, so your repayment stays the same from settlement to payout regardless of what happens in the broader rate environment. This makes budgeting straightforward for operators who want to know exactly what their truck or trailer finance is costing them each month, and it protects you if rates rise during your loan term.
Variable Rates: Flexibility That Moves With The Market
A variable rate can rise or fall over the loan term as the lender's cost of funds changes, meaning your repayment amount may shift periodically. Some operators prefer this structure because it can offer more flexibility around extra repayments or early payout without the break costs that sometimes apply to fixed arrangements, though it does introduce an element of uncertainty into cash flow forecasting.
What Actually Drives Your Rate
Whether you're offered a fixed or variable rate, and where it sits on the scale, depends on factors like your credit history, time in business, the age and type of asset, deposit or no-deposit structure, and whether you're going low-doc or full-doc. As a guide, rates through our lender panel start from 6.55% p.a. for strong applications and can extend up to around 15% p.a. for higher-risk profiles; these figures are indicative only and subject to lender criteria, credit assessment, fees, terms and final approval.
Matching The Rate Type To Your Business
Businesses running tight margins on long-haul contracts often lean toward fixed rates for certainty over a 1 to 7 year term, while those expecting to refinance, upgrade, or pay out early sometimes prefer the flexibility a variable structure can offer. There's no universal right answer, it comes down to your cash flow pattern, growth plans, and appetite for rate movement over the life of the asset.
Doc Type And Deposit Also Shape Your Options
Fixed and variable options are generally available across both ends of the market, from low-doc and lite-doc finance up to $500,000 for ABN holders who prefer simpler paperwork, through to full-doc finance up to $10M+ for larger fleet or asset purchases, subject to approval. No-deposit and up to 100% finance structures may also be available for eligible applicants, which can influence whether a fixed or variable rate makes more sense for your deposit strategy.
Comparing Rather Than Guessing
Because every lender prices fixed and variable truck finance differently based on the same application, the only reliable way to know which structure suits your business is to compare real offers side by side rather than assume. As a broker we compare 80+ banks and non-bank lenders across amounts from $20k to $10M+, matching the rate type, term and structure to your specific circumstances rather than a one-size-fits-all product.
