Fixed vs Variable Rates on Equipment Loans: A Practical Decision Guide

Most Australian businesses taking out equipment finance must pick between a fixed or variable interest rate. Fixed rates lock in the repayment for the term (or for a set period), while variable rates move with market benchmarks like the cash rate and BBSW, so your repayment can rise or fall. The right choice depends less on “guessing the RBA” and more on your cashflow, upgrade plans, and how long you will realistically keep both the gear and the loan.

In this guide we’ll strip out the noise, show worked examples, and give you a decision framework you can use this week before you sign any equipment finance contract.

1. Fixed vs variable equipment rates in plain English

1.1 What is a fixed-rate equipment loan?

A fixed-rate equipment loan is where the lender locks your interest rate for an agreed period – commonly the full loan term (3–7 years) for standard asset finance. Your repayment stays the same for that period, regardless of what happens to the RBA cash rate.

Key features:

• Rate and scheduled repayments don’t change during the fixed period.
• Early payout may attract break costs if market rates have moved.
• Fixed terms commonly align with the loan term on chattel mortgages, leases and hire purchase.

1.2 What is a variable-rate equipment loan?

A variable-rate equipment loan has an interest rate that can move up or down during the term. The lender’s rate is usually linked to a market benchmark (like BBSW) plus a margin, and internal pricing decisions.

Key features:

• Repayments can change when market rates move or the lender reprices.
• Usually more flexible to pay down early or refinance, often with lower or no break costs.
• Can be combined with interest-only periods or restructuring more easily than some fixed facilities.

1.3 Quick answer: when does each generally fit?

For most small businesses:

• Fixed rate usually fits if you want cashflow certainty, plan to keep the gear and loan for most of the term, and would be stressed by higher repayments.
• Variable rate can fit if you expect to upgrade or repay early, want easier restructuring, and can tolerate repayment swings.

We’ll unpack how to judge this for your situation – without trying to outguess the RBA.

2. Why this decision matters more in a 4%+ cash rate world

2.1 Where rates sit now (and why that matters)

The RBA cash rate target rose from 0.10% during COVID to around 4.35% by mid‑2026, before being held at that level in August 2026 amid persistent inflation (RBA Monetary Policy Decisions, May and August 2026). Variable business lending rates have moved broadly in line with this tightening.

What this means for your equipment loan:

1. Repayment swings are now larger. A 1% rate move on a $400,000 5‑year loan can change repayments by hundreds per month.
2. The risk of further changes is real. The RBA has kept policy “somewhat restrictive” and has signalled it may move again if inflation surprises.
3. Margins matter as much as the headline. A sharp rate with the wrong structure can still cost you more over time.

2.2 Fixed vs variable is not just about the “cheapest” rate

It’s tempting to focus only on today’s headline rate. That’s dangerous. As we’ve covered in other contexts, like how much equipment debt is too much, term and structure often matter more than the raw percentage.

For rate type, the big questions are:

• Will a rate shock derail your tax, wages or maintenance?
• How likely are you to change or repay the finance early?
• Are you trading a tiny saving for big flexibility or risk?

We’ll build these into a simple framework shortly.

3. How fixed and variable equipment loans actually work in practice

3.1 Typical fixed-rate equipment structures

On standard commercial equipment facilities (chattel mortgage, lease, hire purchase):

• Terms typically run 3–7 years, matching the realistic working life of the asset, which is more important than chasing the lowest nominal rate.
• The rate is usually fixed for the full term.
• You can add a balloon (residual) to reduce monthly repayments.
• Early payout is allowed but may trigger economic cost or break fees if market rates have moved.

This fits well with the principle that equipment debt should not outlive the asset, a point we explore deeply in our piece on coordinating home, business and equipment finance.

3.2 Typical variable-rate equipment structures

Variable equipment loans can appear as:

• Standard asset finance with a variable margin over BBSW.
• Business loans or overdrafts used to fund equipment purchases.
• Property‑backed facilities (like a commercial loan or home loan top‑up) where the rate is variable.

Be careful: rolling equipment into long‑term property‑backed loans may lower repayments but can materially increase total interest and risk on the home, as we’ve shown in detail across multiple guides.

3.3 Cashflow impact – worked example

Assume you’re buying a $200,000 excavator on a 5‑year chattel mortgage with no balloon. Compare:

• Fixed rate: 8.50% p.a.
• Variable rate: 8.00% p.a. today, but could move.

Approximate monthly principal and interest repayment:

• Fixed 8.50%: about $4,106 per month.
• Variable 8.00%: about $4,055 per month initially.

Difference: only ~$51 per month at the start.

If variable rates rise to 9.00% next year and stay there:

• New repayment would jump to around $4,179 per month.
• You’d be paying more than the fixed option from that point on.

The lesson: don’t over‑weight a small initial saving if a rate rise would hurt.

4. Pros and cons: fixed vs variable equipment rates

4.1 Side‑by‑side comparison

4.2 Pros and cons list – fixed rate

Pros:

• Predictable repayments support tight cashflow and staffing decisions.
• Easier to price long‑term contracts or tenders.
• Protects you from future rate spikes during the fixed term.
• Often aligns well with short, asset‑matched terms (3–7 years).

Cons:

• Break costs can apply if you sell, upgrade or refinance early.
• You won’t automatically benefit if rates fall.
• May be priced slightly higher than the lender’s variable offer at the start.

4.3 Pros and cons list – variable rate

Pros:

• Can benefit from any future rate cuts.
• Often more flexible for early payout or restructuring.
• May start a touch cheaper than the equivalent fixed rate.

Cons:

• Repayments can jump if the RBA or markets move up.
• Harder to lock in margins on tight projects.
• More psychological load – watching rates and cashflow closely.

5. Cashflow stress: how much rate risk can your business handle?

5.1 A simple repayment stress test

Use this quick method before you decide:

1. Calculate today’s repayment on your proposed loan.
2. Add 2% to the rate and recalculate.
3. Ask: could we still pay this every month if sales dipped 20% for 6–12 months?

Example: $300,000 loan over 5 years, no balloon.

• At 8.0% variable: repayment ≈ $6,084/month.
• At 10.0% (a 2% rise): repayment ≈ $6,373/month.

That’s ~$289/month more. Not huge in absolute terms, but if you have several loans, it adds up.

If a 2% rise would push you into delaying BAS, cutting staff or deferring maintenance, you’re probably a better candidate for fixing at least part of your equipment debt.

5.2 Link to broader leverage risk

This decision also interacts with your overall leverage, as covered in how much equipment debt is too much. If total equipment repayments are already pushing 15–25% of stable revenue:

• Variable rates amplify risk – repayments can spike just as revenue softens.
• Fixed rates won’t reduce the size of the commitment, but they cap one source of uncertainty.

In a world where almost 30% of mortgage holders are already ‘At Risk’ of stress (Roy Morgan, 2026), layering unpredictable business repayments on top deserves serious thought.
