The total cost of truck finance is everything you pay across the life of the loan: the amount you borrow, plus all the interest, plus every fee. It is the single most useful figure for comparing offers, because a low rate loaded with fees can cost more than a slightly higher rate with none. Working it out is straightforward once you know the pieces. At Overdrive we compare 80+ banks and non-bank lenders on total cost, so you judge the real number, not the headline.
Key highlights
- Total cost is principal plus all interest plus all fees
- It is the true figure to compare, not the rate alone
- Term, balloon and deposit all shift the total
- A low rate with high fees can cost more overall

What total cost actually includes
Total cost is the sum of everything you hand over during the loan. That means the principal, the amount you borrowed, plus all the interest charged across the term, plus every fee, establishment, ongoing account and any exit costs. If there is a balloon, the final lump sum forms part of the picture too. The headline interest rate is only one input into this figure. Two loans advertised at the same rate can produce different total costs once fees and structure differ, which is exactly why total cost, not rate, is the number worth comparing.
Why the rate alone misleads
A sharp advertised rate is attractive, but it does not tell you what the loan costs. A lender can quote a keen rate and recover its margin through higher fees, while another with a slightly higher rate charges little and works out cheaper overall. As a general guide, strong, asset-backed deals can start from around 6.55% p.a., indicative and subject to lender assessment, but that percentage only becomes meaningful when you add the fees and see the full repayment total. Judging a loan on rate alone is how operators end up paying more than they expected over the term.
How structure moves the total
The way a loan is structured shifts its total cost significantly. A longer term lowers each repayment but adds interest over more years, raising the total. A balloon or residual reduces regular repayments but leaves a lump sum to settle later and usually increases total interest, since more of the truck is financed for longer. A deposit or trade-in works the other way, cutting the amount financed and the total paid. Terms typically run 1 to 7 years. The same truck can carry very different total costs depending purely on how the finance is arranged.
Comparing offers on a level footing
To compare fairly, put each offer on the same basis: same truck price, same deposit, same term, then look at the total repayments including fees. On that footing, the genuinely cheapest option is obvious, and any offer weighed down by heavy fees stands out even if its rate looked sharp. This is the practical value of comparison. Rather than trusting a headline percentage, you see what each lender's deal actually costs you in full over the term, which is the only number that truly matters when the loan runs for several years and every dollar counts.
Total cost and tax
How interest and fees are treated for tax and GST depends on the finance structure and your circumstances, and it can affect the effective cost to your business. This is general information only, so check with your accountant, particularly around depreciation, GST treatment and any instant asset write-off timing. From a pure comparison standpoint, though, the total repayment figure remains the cleanest way to line up lenders against each other before tax considerations are layered on. Get the total cost clear first, then let your accountant advise on the tax position.

Frequently Asked Questions
How do I calculate the total cost of a truck loan?
Add the amount borrowed to all the interest charged over the term and every fee, including establishment, ongoing account and any exit costs. Include any balloon in the picture. A repayment calculator makes this quick. The result is the true figure to compare between lenders, rather than the headline interest rate alone.
Why is total cost better than the interest rate?
Because a low rate can hide high fees. A lender may quote a sharp rate and recover margin through charges, while a slightly higher rate with few fees costs less overall. Total cost captures everything you pay, so it is the only figure that reliably tells you which loan is genuinely cheaper.
Does a balloon payment raise the total cost?
Usually, yes. A balloon lowers your regular repayments but leaves a lump sum to settle at the end, and because more of the truck stays financed for longer, total interest tends to rise. It can still suit cash flow, but weigh the easier repayments against the higher total, subject to lender criteria.
How can I compare lenders on total cost?
Put every offer on the same footing, same truck price, deposit and term, then compare total repayments including all fees. Any offer weighed down by heavy fees stands out even if its rate looked sharp. A broker can lay lenders out this way, so you judge the real number, not the headline.
