TL;DR: The headline rate is the easiest number to advertise and the easiest to game. Establishment and monthly fees, PPSR charges, a long term and a balloon at the end can make a 'cheaper' rate cost thousands more. Compare the total cost of credit — the full dollar figure you repay — not the percentage on the poster.
---
We see plenty of tradies pick the wrong loan for the right reason. They spot a lower rate, they back it, and they end up paying more. Not because they're dumb — because the rate is the one number everyone shows you, and it's the one number that hides the most.
Here's what we tell every client: the rate is marketing. The total cost of credit is the deal.
## Why the headline rate lies
The advertised rate — the big number on the poster — only describes the interest charged on the money you borrow. It says nothing about the fees bolted on around it, the length of the term, or what happens at the end. A lender can run a genuinely low rate and still make the loan cost you more than a "higher rate" deal down the road. That's not a scam. It's just how the maths works when you only look at one variable.
Four things sit outside the headline rate and quietly do the damage.
### 1. The fees nobody puts on the poster
Every loan carries costs that aren't interest. Typically you'll see some mix of:
- **Establishment / documentation fee** — a one-off charge to set the loan up. This can run anywhere from modest to several hundred dollars.
- **Monthly account or admin fee** — small per month, but multiply it over a 5-year term and it adds up to real money.
- **PPSR registration fee** — to register the lender's [security interest on the PPSR](/glossary/security-interest-ppsr) (the public register that records who has a claim over your ute or gear). Small, but it's there.
- **Broker or origination fees** — if any apply, they should be disclosed up front. Ask.
None of these show up in the headline rate. All of them show up in what you actually repay.
### 2. The term length trick
A longer term lowers your monthly repayment, which feels cheaper — and it's the easiest way to make a deal look affordable. But you pay interest for longer, so the total you hand over goes up. Stretch a loan from 3 years to 5 and your monthly drops nicely while your total cost climbs. There's nothing wrong with a longer term if the cashflow needs it — just don't mistake a smaller repayment for a cheaper loan. They're different things.
### 3. The balloon at the end
A [balloon payment](/glossary/balloon-payment) (sometimes called a residual) is a big lump sum left to pay at the end of the term. Lenders love advertising loans with balloons because the structure lets them show a low rate *and* a low monthly repayment — the catch is the chunk waiting for you at the finish line. You either find the cash, refinance it (more interest), or trade the vehicle to clear it. A balloon isn't automatically bad, but a quote with a hidden balloon will always look cheaper than an honest quote without one. Compare like with like.
### 4. How the interest is charged
Two loans at the same rate can still cost different amounts depending on how interest is calculated and how often it compounds. This is the deep-in-the-weeds bit, and it's exactly why you don't compare rates head-to-head — you compare the dollar total.
Ask every lender the same thing: 'What is the total amount I will repay over the full term, including every fee and any balloon?' One number. If they can't give it to you simply, that tells you something.
## The number that actually matters: total cost of credit
The [total cost of credit](/glossary/total-cost-of-credit) is the full dollar figure — everything you repay above what you borrowed: all the interest, plus every fee, over the whole term. It's the honest answer to "what does this loan cost me?"
There's also a tool built to make rates comparable: the [comparison rate](/glossary/comparison-rate). It rolls the interest rate and the standard fees into a single percentage so you can line up two deals fairly. It's a useful sniff test — but it still won't capture a balloon or non-standard fees, so treat the comparison rate as a shortcut and the total cost of credit as the real decider.
## A worked example — when the lower rate costs more
Two lenders, same $50,000 work ute, financed by [chattel mortgage](/glossary/chattel-mortgage). These numbers are illustrative — your actual rates and fees will differ, and they're not offers — but the shape of it is exactly what we see week in, week out.
| | Lender A — the 'cheap rate' | Lender B — the boring one |
|---|---|---|
| Headline rate | 8.5% | 9.5% |
| Term | 5 years | 4 years |
| Establishment fee | $495 | $295 |
| Monthly account fee | $12 | $0 |
| Balloon at end | $10,000 | $0 |
| Roughly what you repay | higher total | lower total |
Lender A wins the poster with 8.5%. But look at what's hiding behind it: an extra year of interest, a fatter establishment fee, a monthly fee running for 60 months instead of nothing, and a $10,000 balloon you still have to clear at the end. Add the interest over the longer term, the 60 months of account fees, and that balloon, and Lender A's "cheaper" loan costs you meaningfully more across the life of it — often a few thousand dollars on a deal this size.
Lender B's higher rate, shorter term and clean fee structure gets you debt-free a year sooner with no lump sum lurking. That's the cheaper deal. The poster said otherwise.
The cheapest rate and the cheapest loan are rarely the same loan.
## How to actually compare quotes
When you've got two or three quotes on the table, do this:
1. **Make them all the same term.** You can't compare a 3-year quote to a 5-year quote. Ask each lender to quote the same term.
2. **Strip out the balloons — or include them in everyone's.** A quote with a balloon and a quote without one are different products. Line them up properly.
3. **Add every fee in.** Establishment, monthly, PPSR, any broker fee. Put them in the total.
4. **Ask for the total repayable, in dollars.** Then compare those numbers, not the percentages.
5. **Sense-check the structure against your cashflow.** A slightly dearer loan that's gone in 3 years can beat a cheap one that drags for 5 — but only if the repayments fit. If your work is seasonal, that matters; see our guide on [managing seasonal cashflow as a tradie](/guides/managing-seasonal-cashflow-as-a-tradie).

## Where the rate genuinely matters — and where it doesn't
None of this means ignore the rate. On a like-for-like deal — same term, same structure, same fees — a lower rate is straight-up better, and you should chase it. The mistake is comparing the rate *across* deals that aren't like-for-like. That's where tradies get caught.
A couple of other things worth knowing:
- **Paying it off early.** Some loans let you clear the balance early and save interest; others charge a break fee that eats the saving. Worth asking before you sign — more on that in [can I pay off tradie finance early](/help/can-i-pay-off-tradie-finance-early).
- **A cheap rate with a long chain of fees** can be a sign a lender is making its margin in the small print. The honest deal is usually the one that's easy to total up.
## What being a broker changes here
We'll be straight about this, because it's literally our job. We're a broker, not a lender — we don't have one rate to push. We place your application across a panel of lenders and lay the deals out on a total-cost basis, not a headline-rate basis. That means we can spot the balloon hiding in Lender A's quote and tell you the boring loan from Lender B is actually the cheaper one. The percentage on the poster is the lender's marketing. The total dollar figure is your decision — and that's the number we work from.
If you've got a couple of quotes and you're not sure which one's genuinely cheaper, send them over. We'll total them up properly, structure it around your cashflow, and tell you straight which deal wins — no pressure, no sales pitch.
