Getting the numbers right before you commit to equipment finance means looking beyond the sticker price and working out what the purchase actually costs your business each month.
Most self-employed business owners need to balance two competing priorities: acquiring the equipment that makes the business viable, and preserving enough working capital to deal with the gaps between invoicing and getting paid. The budgeting part is where those two priorities either align or collide.
What Asset Finance Actually Costs Your Business
The true cost of financed equipment includes the loan amount, the interest you'll pay over the term, any balloon payment at the end, and the tax benefit you receive through depreciation. A chattel mortgage on a $60,000 excavator over five years might involve fixed monthly repayments around $1,200, a balloon payment of $15,000 at the end, and a depreciation deduction that reduces your taxable income each year. The monthly cost to your cashflow is the repayment amount, not the purchase price.
Consider a landscaping business that needs a second truck and trailer. The equipment costs $75,000. With a chattel mortgage and a 20% balloon payment, the monthly repayment sits around $1,400. The business invoices $30,000 a month but receives payment 30 to 45 days later. Budgeting for the truck means confirming that $1,400 can be met even during the months when two large invoices are still outstanding. That's not about affordability in the abstract, it's about cashflow timing.
How Balloon Payments Affect Your Monthly Budget
A balloon payment reduces your monthly repayments by deferring a lump sum to the end of the loan term. This structure works when you want lower monthly commitments now and can either refinance or sell the asset to clear the balloon later. The downside is that the balloon still accrues interest over the life of the lease, so you pay more in total.
If your business generates uneven income, a balloon payment can give you breathing room during slower months. A mobile mechanic financing $40,000 worth of diagnostic equipment might choose a 30% balloon to keep monthly repayments at $800 instead of $1,100. That $300 difference each month stays in the business to cover parts, fuel, and the weeks when work slows down. The trade-off is a $12,000 payment due at the end of the term, which needs to be planned for separately.
Structuring Finance Around Your Income Cycle
Self-employed income rarely arrives in neat monthly instalments. Seasonal businesses, project-based contractors, and anyone reliant on a few large clients will have months where income doubles and months where it halves. Your finance structure should reflect that reality, not ignore it.
A builder who takes on commercial fit-outs might wait 60 days for progress payments. If they're financing a $90,000 excavator and tipper through a chattel mortgage, the monthly repayment of around $1,800 needs to come out of reserves during the lead time on new projects. The way to budget for that is to calculate how many months of repayments you need to hold in reserve based on your longest typical gap between completing work and receiving payment. For most self-employed operators, that's two to three months.
Tax Benefits and How They Change the Real Cost
When you finance equipment under a chattel mortgage, you can claim the interest as a deductible expense and depreciate the asset over its effective life. The depreciation deduction reduces your taxable income, which lowers the after-tax cost of the purchase. If you're paying a marginal tax rate of 32.5%, a $1,200 monthly repayment might only cost you $810 after factoring in the tax benefit from depreciation and interest.
This doesn't change your monthly cashflow directly, but it does mean your business keeps more of what it earns at tax time. Some self-employed business owners use this to structure a tax strategy where the equipment purchase brings down taxable profit in a strong year, smoothing out the business's tax position over time. You still need to fund the repayments in real time, but the net cost to the business over the term is lower than the face value of the loan.
Comparing Finance Options for Different Equipment Types
A chattel mortgage works well for equipment you intend to own and use long-term. A finance lease can make sense if you want to upgrade regularly and prefer to return the equipment at the end rather than own it outright. The lease structure typically includes the GST in the repayments, which you claim back if you're registered for GST, and the lease payments are fully deductible.
For a café owner financing $50,000 worth of coffee machines, grinders, and refrigeration, a finance lease might suit an upgrade cycle of three to four years. The monthly cost is slightly higher than a chattel mortgage, but there's no balloon payment and no need to sell the equipment when it's time to upgrade. For a plumber buying a $35,000 van they'll drive into the ground over ten years, a chattel mortgage with a smaller balloon makes more sense because the goal is ownership, not turnover.
Building Contingency into Your Equipment Budget
Financing new equipment only works if the business can still operate when something else breaks, a client delays payment, or a job falls through. The contingency you need depends on how lumpy your income is and how much of your revenue relies on the equipment you're financing.
A concreting business financing a $120,000 truck and trailer might budget for the $2,400 monthly repayment, but also needs to keep $7,000 to $10,000 in reserve to cover the months when wet weather kills a fortnight of work. That reserve isn't part of the loan, it's part of the broader cashflow plan that makes the loan sustainable. If you're using vendor finance or dealer finance, the approval process will look at your income, but it won't always account for variability. That part is on you.
When to Finance and When to Wait
Not every equipment purchase should be financed immediately. If your business is still building consistent revenue, or if the equipment isn't directly tied to delivering a service you're already contracted for, waiting until your cashflow stabilises makes more sense than borrowing early and hoping the work follows.
The decision point is whether the equipment pays for itself through additional work or increased capacity. If financing a $50,000 piece of machinery means you can take on jobs you'd otherwise turn down, and those jobs cover the repayments with margin to spare, the timing is right. If the equipment is speculative or requires a new type of client you haven't yet secured, delay the purchase and build the client base first.

Frequently Asked Questions
How do I calculate the real monthly cost of financed equipment?
The monthly cost includes your fixed repayment amount, minus the tax benefit from depreciation and interest deductions. For example, a $1,200 repayment might only cost $810 after tax if you're on a 32.5% marginal rate. This doesn't change your cashflow timing, but it reduces the net cost over the term.
Should I use a balloon payment to reduce monthly repayments?
A balloon payment lowers your monthly commitment by deferring a lump sum to the end of the term, which helps with cashflow if your income is uneven. The trade-off is that you pay more interest overall and need to plan for the balloon payment separately, either by refinancing or selling the asset.
How much contingency should I keep when financing equipment?
Most self-employed business owners should hold two to three months of repayments in reserve to cover the gap between completing work and receiving payment. If your income is seasonal or project-based, you may need more depending on your longest typical payment delay.
What's the difference between a chattel mortgage and a finance lease for budgeting?
A chattel mortgage has lower monthly repayments and leads to ownership, but may include a balloon payment. A finance lease has slightly higher repayments with no balloon, and you return the equipment at the end. Lease payments are fully deductible, while a chattel mortgage lets you claim depreciation and interest.
When should I wait instead of financing equipment now?
Wait if your cashflow isn't consistent yet, or if the equipment doesn't directly support work you're already contracted for. Finance when the equipment pays for itself through additional capacity or jobs you'd otherwise turn down, and your income can cover the repayments during slower months.
