The cost of financing a truck comes down to four things: how much you borrow, your interest rate, the loan term, and the fees involved. A larger loan, a higher rate or a longer term all raise the total you repay, while a deposit and a shorter term reduce it. The real figure only appears once you add fees to the rate. At Overdrive we compare 80+ banks and non-bank lenders on one application, so you can see the true cost across the market.
Key highlights
- Cost depends on amount, rate, term and fees combined
- A longer term lowers repayments but raises total interest
- A deposit reduces both the amount financed and total cost
- Compare total repayments, not just the headline rate

The four things that set your cost
Financing a truck has four main cost drivers. The amount borrowed sets the base. The interest rate determines how much you pay on top of that. The term decides how long you pay for and how interest accumulates. And the fees, establishment, ongoing and any exit costs, add to the total. As a general guide, strong, asset-backed deals can start from around 6.55% p.a., with weaker credit, lower-doc or older trucks priced higher. These figures are indicative and subject to lender assessment. Change any one of these four and your total cost moves, sometimes substantially.
How the term changes the maths
The loan term has a bigger effect than many operators expect. A longer term spreads the loan over more payments, so each repayment is smaller and easier on monthly cash flow. But because you are borrowing for longer, you pay interest for longer, so the total cost rises. A shorter term does the opposite: higher repayments but less total interest. Terms typically run 1 to 7 years, and choosing between them is a genuine trade-off between monthly affordability and total cost. The right choice depends on your cash flow and how long the truck will earn.
The role of a deposit and balloon
A deposit or trade-in reduces the amount financed, which lowers both your repayments and the total interest paid, and it can support a sharper rate by cutting the lender's risk. A balloon or residual payment works differently: it parks a lump sum at the end of the term, reducing your regular repayments but leaving a large final amount to pay, refinance or clear from the truck's sale. A balloon eases monthly cash flow but usually increases total interest, since you are financing more of the truck for longer, subject to lender criteria.
Fees add to the picture
The rate is not the full cost. An establishment or documentation fee applies at the start, ongoing account fees may apply through the term, and early-termination costs can apply if you exit ahead of schedule. Two loans with the same rate can cost different amounts once fees are counted, which is why comparing on total cost matters. When you look at the whole package, a slightly higher rate with low fees can beat a lower rate loaded with charges. Always ask for the total cost over the term, not just the advertised percentage.
A worked way to think about it
The clearest approach is to model the total repayments for your actual scenario rather than relying on a single rate. Take the truck price, subtract any deposit or trade-in, apply an indicative rate and your chosen term, and add the fees to see the full cost. Then repeat with a different term or a balloon to compare. A repayment calculator makes this quick, and comparing several lenders' offers on the same basis shows which is genuinely cheapest for you. This is far more useful than assuming the lowest advertised rate wins.

Frequently Asked Questions
What determines how much truck finance costs?
Four factors: the amount borrowed, your interest rate, the loan term and the fees. A larger loan, higher rate or longer term all raise the total, while a deposit and shorter term reduce it. The true cost only appears once fees are added to the rate, so compare total repayments across lenders.
Does a longer term make a truck cheaper?
It lowers your monthly repayment but raises the total cost, because you pay interest over more years. A shorter term costs more each month but less overall. The right term balances monthly affordability against total cost and how long the truck will keep earning, subject to lender criteria and assessment.
How does a balloon payment affect the cost?
A balloon parks a lump sum at the end of the term, lowering your regular repayments but leaving a large final amount to pay, refinance or clear from the truck's sale. It eases monthly cash flow but usually increases total interest, since more of the truck is financed for longer, subject to lender criteria.
Should I compare the rate or the total cost?
Total cost. Two loans with the same rate can cost different amounts once establishment, account and exit fees are included. A slightly higher rate with low fees can beat a cheaper-looking rate loaded with charges. Always ask for the total cost over the full term rather than the headline percentage alone.
