Key Takeaways
- Separate three different numbers: your headline day rate, a realistic annualised figure once non-billable time is factored in, and the figure a specific lender will actually use, they’re rarely the same.
- Multiplying your rate by 52 weeks overstates your income; lenders typically apply a more conservative working-week assumption to account for public holidays, unpaid leave and gaps between contracts.
- A lower day rate backed by a long remaining contract term and a history of renewals can present more favourably to a lender than a higher rate with little time or continuity behind it.
- Once your income is assessed, it still needs to run through your existing debts, living expenses and a serviceability buffer, so a strong annualised figure is only the starting point for your actual borrowing capacity.
If you’ve moved from a permanent salary into contracting, or you’re weighing up whether to make that move, you’ve probably already done the obvious maths. A $900 day rate multiplied across a working year looks a lot bigger than your old salary, and it’s tempting to assume a lender will see the same impressive number you do. The trouble is, a home loan application asks a genuinely different question than a simple pay comparison does, and the gap between those two questions can meaningfully change what you’re actually able to borrow.
A salary comparison tool asks whether you’re financially better off contracting. A lender asks something narrower and more specific: how much of this income is reliable and sustainable enough to service a mortgage over many years. Those two questions can produce very different numbers from the exact same day rate, which is why plenty of borrowers are caught off guard when their “obviously higher” contract income doesn’t translate into the borrowing capacity they expected.
This article walks through exactly how a lender bridges that gap, from your headline rate through to the figure they’ll actually use, so you can go into your application with realistic expectations rather than your own back-of-envelope calculation.
The three income numbers every contractor needs to separate
Before anything else, it’s worth understanding that there isn’t just one number here, there are genuinely three, and confusing them is where most of the misunderstanding in this topic comes from.
Your headline contract rate
This is the number you quote when someone asks what you earn, your $900 or $1,000 a day, or your hourly rate. It’s real, but it’s not an annual income figure on its own, it’s a price per unit of time worked.
Your realistic annual contract income
This is what your rate actually produces once you account for the fact that you’re not billing every single day of the year. It requires converting your rate into an annualised figure using a genuinely realistic number of working periods, which we’ll walk through properly below.
Your lender-assessed income
This is the figure a specific lender is actually willing to use in their serviceability calculation. It might match your realistic annual income, or it might be lower, depending on how long you’ve been contracting, how you’re engaged, how much time remains on your current contract, and that particular lender’s policy.
Most of the confusion in this whole topic comes from treating these three numbers as though they’re all the same thing. They usually aren’t, and understanding the gaps between them is the real skill here.
Contract rate versus salary: what’s actually different
Before working through the calculations, it helps to see clearly why a contract rate and a salary aren’t a like-for-like comparison in the first place.
| Permanent salary | Contractor rate | |
| Headline figure | $160,000 per year | $900 per day |
| Paid annual leave | Yes, included | Usually not, unless self-funded |
| Paid public holidays | Yes, included | Usually not |
| Paid sick leave | Often included | Usually not |
| Superannuation | Usually paid on top by the employer | Depends on the arrangement |
| Income continuity | Ongoing, subject to notice periods | Tied to the length of the current contract |
| Typical evidence for a home loan | Payslips and employment contract | Contract, plus payslips, invoices or BAS depending on structure |
A permanent salary keeps paying you through leave, public holidays and, in many cases, illness. A contract rate, in most arrangements, only pays you for time actually worked or billed. That single difference is why multiplying a day rate across a full 52-week year overstates what you’re genuinely earning, let alone what a lender will use.
How a lender turns a day rate into annual income
This is the centrepiece of the whole topic, and it’s worth working through slowly because it’s where the real difference between expectation and outcome tends to show up.
Say your rate is $1,000 a day, five days a week. If you assumed a full 52 weeks, you’d land on $260,000. But a full year contains public holidays, and most contractors don’t get paid annual leave or sick leave, so a genuinely realistic figure needs to account for the days you’re realistically not billing.
| Assumption | Working weeks used | Resulting annual figure |
| Full calendar year, no adjustment | 52 weeks | $260,000 |
| A more realistic, conservative estimate | 46 weeks | $230,000 |
That gap, $30,000 in this example, isn’t a rounding error, it’s a genuine reflection of the days a contractor typically doesn’t bill: public holidays, any downtime between engagements, and time off that a salaried employee would have paid for automatically. It’s worth being clear that 46 weeks isn’t a universal figure every lender applies, some may use a different assumption entirely, or rely on your actual verified earnings over a specific period instead of a generic weekly assumption. The point isn’t the exact number, it’s understanding that some downward adjustment from a full 52-week calculation is standard practice, not a penalty.
Why you can’t simply multiply your rate by 52 weeks
It’s worth spelling out exactly why this adjustment exists, because it explains a lot of the gap between what contractors expect their income to look like and what actually gets used.
- Public holidays generally aren’t billable for a contractor, even though a salaried employee is paid for them
- Annual leave and sick leave typically aren’t paid unless a contractor has specifically arranged and funded that themselves
- There’s a genuine possibility of gaps between contracts, whether a short break while sourcing the next engagement, or a slower period between projects
None of this is a judgement on how stable or valuable your work actually is. It’s simply a reflection of how contract income is structured compared to a salary, and a realistic annual figure needs to account for that structural difference rather than assuming every single weekday of the year is billable.
How hourly contract rates are annualised
The same logic applies if you’re paid by the hour rather than by the day, just with an extra step in the calculation.
Take an hourly rate of $120, worked eight hours a day, five days a week. At 46 working weeks, that comes to roughly $220,800. As with the day-rate example, this figure still needs to be weighed against your actual contracted hours, any unpaid leave, and how long your current engagement runs for, rather than being treated as a fixed, guaranteed annual figure on its own.
Does GST count as part of your income
This is a genuinely important distinction if you’re contracting through your own Australian Business Number (ABN), and it’s easy to get wrong if you’re not thinking about it carefully. If you invoice a client $1,100 a day including Goods and Services Tax (GST), that full $1,100 isn’t your actual income. The GST component is money you’re collecting on behalf of the Australian Taxation Office (ATO), which you generally need to remit, it was never genuinely yours to keep or spend. A lender assessing your income is going to be interested in your revenue excluding GST, so it’s worth making sure your own figures reflect that distinction clearly, rather than accidentally overstating what you actually earn.
How does superannuation affect the comparison
This is another area where headline figures can genuinely mislead you if you’re not careful, and it’s worth separating out clearly.
- A salary of $160,000 with superannuation paid on top by your employer is a different figure to a $180,000 “package” that already includes superannuation within it
- A contractor’s quoted day rate, depending on the arrangement, may need to fund their own superannuation contributions, rather than having them paid separately
Comparing a $900 day-rate contract against a $160,000 salary without accounting for who’s actually funding superannuation in each case is comparing two different things dressed up to look similar. It’s worth being clear on where your own figures sit before drawing any conclusions about which arrangement is actually paying you more.
PAYG contractor versus ABN contractor
How you’re actually engaged changes almost everything about how your income gets assessed, and it’s worth being clear on which category applies to you.
| PAYG contractor | ABN or Pty Ltd contractor | |
| Who pays you | An employer or recruitment agency | Your client, directly |
| Tax withheld | Usually by the payer | Usually self-managed |
| Typical lender treatment | Often closer to a standard employee | Often assessed more like a self-employed borrower |
| Common evidence | Contract, payslips, bank credits | Invoices, BAS, tax returns, business bank statements |
Two people charging an identical $1,000 day rate can end up with quite different lender-assessed incomes purely because of this distinction. A PAYG contractor with payslips and tax withheld by an agency is a genuinely different proposition, from a documentation and assessment standpoint, to someone invoicing directly through their own ABN and managing their own tax and business expenses.
Can the lender use your new contract rate instead of your old salary
This is one of the most financially significant questions in this entire topic, and the answer genuinely depends on which lender you’re speaking with. Imagine your previous permanent salary was $155,000, and your new contract, once annualised at 46 weeks, comes to roughly $218,500. Some lenders will be comfortable using that current, higher contract figure as your primary income, provided it’s well documented and your contract has a reasonable amount of time left to run. Others may lean more heavily on your historical salary or tax return, particularly if your contracting arrangement is very recent, which can mean your assessed income sits closer to your old figure than your new one. This single policy difference can shift your borrowing capacity considerably, which is exactly why getting matched to a lender that recognises current contract income matters so much here.
Why remaining contract term matters
Beyond the rate itself, a lender is also thinking about how much certainty exists around that income continuing, and this genuinely affects the outcome even at an identical day rate.
A strong remaining term
A contract with, say, ten months remaining gives a lender good visibility and reasonable confidence your income will continue in the near term.
A short remaining term with a renewal history
If you’re down to a few weeks remaining, but you’ve had this contract, or similar contracts, renewed before, that history genuinely helps. A letter from your agency or client confirming an intention to renew can meaningfully strengthen this kind of application.
A short remaining term with no history
This is the hardest scenario to work with, particularly for a first-time contractor with no longer track record to point to. It’s worth comparing two contractors directly here: one earning $1,100 a day with four weeks remaining and no renewal evidence, against another earning $900 a day with ten months remaining and a three-year history of renewals. The second contractor, despite the lower headline rate, is often in the stronger position from a lender’s point of view.
What if you’ve had rolling contracts for years
This is a genuinely strong position, and it’s worth making explicit in your application rather than assuming a lender will simply notice it. Many contractors, particularly in fields like IT, project management, engineering and government work, move through a series of three, six or twelve-month contracts that renew repeatedly, sometimes with the same client for years. A lender who only looks at the fact that your current agreement technically expires in a few weeks, without seeing the broader pattern, is missing the real picture. If you can demonstrate several years of continuous, rolling engagements, that’s a considerably stronger continuity story than the current contract’s end date alone would suggest.
Does previous permanent employment help
Yes, particularly if you’ve stayed in the same field. A software developer who spent six years on a $150,000 permanent salary before moving into contracting at $900 a day, doing essentially the same type of work, has a genuinely different risk profile to someone moving into an entirely new occupation. Some lenders will treat that prior PAYG history in the same field as supporting evidence of your earning capacity and continuity, which can help offset the fact that your contracting arrangement itself is still relatively new. It’s worth understanding, though, that this generally supports your current application rather than replacing the need for your current contract income to genuinely stand on its own.
What documents you’ll need
The right document pack depends heavily on how you’re engaged, so it’s worth preparing accordingly.
If you’re a PAYG contractor
- Your current signed contract, whether directly with an employer or through an agency
- Recent payslips
- Bank statements showing consistent income credits
- A letter confirming ongoing work or an intention to renew, where available
If you’re an ABN or Pty Ltd contractor
- Your current client contract or service agreement
- Recent invoices issued to clients
- BAS, particularly valuable if a full tax return isn’t yet available
- Business bank statements
- Your tax returns, where completed
Contract income isn’t the same as borrowing capacity
Once a lender has settled on an assessed income figure, that’s genuinely just the starting point, not the answer to how much you can borrow. From there, they’ll factor in your existing commitments and living costs before arriving at an actual borrowing capacity.
- Existing home loans or other mortgage commitments
- Personal loans and car loans
- HELP or other government debt
- Credit card limits, often assessed at the full limit rather than your current balance
- Dependants and general living expenses
- A serviceability buffer, an assessment margin most lenders add on top of current interest rates to make sure you could still afford repayments if rates rose
A high annualised contract income is a genuinely good starting point, but it’s only one half of the equation. Two contractors with identical assessed incomes can end up with quite different borrowing capacities once their existing debts and living expenses are factored in.
A first-home-buyer scenario
Consider a PAYG IT contractor who spent six years as a permanent employee earning $145,000, before moving into contracting eight months ago at $850 a day, with roughly eight months remaining on the current agreement. They have a 20 per cent deposit and consistent payslips through their contracting agency. Annualised at 46 working weeks, that day rate comes to approximately $195,500, a genuine increase on their previous salary. Combined with their same-industry history and a reasonable remaining contract term, this is a solid starting position. Whether that translates into a strong final outcome still depends on the rest of the picture, their existing debts, living expenses, and which lender’s policy they’re matched to, since the annualised income figure is only the first step in the calculation, not the final answer.
If you’re using contract income to buy your first property, it can help to understand the deposit, LVR and lender-policy considerations that apply to first home buyers before you apply. If you already have a mortgage and have since moved from salary to contracting, reviewing your refinance options can also help you see which lenders may be more comfortable using your current contract income and employment structure.
Refinancing after moving from salary to contract work
If you took out your current home loan while you were a permanent employee and have since moved into contracting, it’s worth understanding that refinancing triggers a genuinely fresh assessment with the new lender. Your excellent repayment history with your existing lender doesn’t automatically carry across, since a new lender will assess your current contracting arrangement, rate, structure and remaining term, from scratch. It’s worth checking your realistic position before assuming refinancing will be a formality simply because your current loan has been well managed.
Buying an investment property on contract income
If you’re considering an investment property rather than a home to live in, the same annualisation and continuity principles apply, but they sit alongside a few additional layers. A lender will typically assess your contract income alongside your existing mortgage commitments and the rental income the new property is expected to generate, and investment lending is generally assessed a touch more conservatively than owner-occupier lending overall. A strong day rate alone won’t carry an investment application, it’s genuinely worth mapping out your full financial picture before assuming your contract income comfortably supports an additional purchase.
Will you pay a higher interest rate as a contractor
Not necessarily, and this is worth clarifying because it’s a common assumption. Being paid a contract rate rather than a salary doesn’t, on its own, set your interest rate. If your documentation and history are strong enough to access a mainstream lending pathway, you can often access the same rates as a salaried borrower. Pricing tends to shift where your specific circumstances mean an alternative-documentation or specialist lending pathway is the more realistic route, since narrower lender choice in that situation can affect the rates and fees genuinely available to you, rather than the fact that you’re paid via a contract rate at all.
How a mortgage broker can help calculate your usable contract income
This is exactly the kind of situation where matching your circumstances to the right lender policy makes a real difference, because the variation between lenders on annualisation, continuity requirements, and current-versus-historical income treatment is genuinely significant. We can help you work out whether you’re better positioned as a PAYG or ABN contractor, how a specific lender is likely to annualise your rate, whether your current contract income or an older salary figure is likely to be used, and how much weight a lender will give to your remaining contract term. We can also help you understand how your assessed income interacts with your existing debts and living expenses to arrive at a genuine borrowing capacity, rather than stopping at the annualised income figure alone. Getting these details right before you apply is what turns a strong day rate into an accurate, dependable picture of what you can actually borrow.
Frequently Asked Questions (FAQs)
1. Can I just multiply my day rate by 52 weeks to estimate my mortgage income?
It’s not advisable to rely on this figure. A full 52-week calculation doesn’t account for public holidays, unpaid leave, or gaps between contracts, all of which reduce how much a contractor genuinely bills across a year. Lenders typically apply a more conservative number of working weeks or rely on your actual verified earnings instead.
2. How many working weeks do lenders use for contractor income?
There’s no single universal figure. Some lenders may use something in the mid-forties as a general assumption, while others rely on your actual, verified earnings over a specific period rather than a fixed weekly formula. It’s worth confirming directly with your broker how a particular lender approaches this calculation.
3. Does GST count as income for an ABN contractor?
No. If your invoiced rate includes GST, that portion is generally collected on behalf of the Australian Taxation Office rather than being your actual income. Lenders will typically look at your revenue excluding GST when assessing what you earn.
4. Can a lender use my current, higher contract rate instead of my old salary?
Some lenders will, particularly where your current contract is well documented and has reasonable time remaining. Others may rely more heavily on your historical salary or tax return figures, especially if your contracting history is quite recent. This is a genuine point of difference between lenders, so it’s worth clarifying which approach applies to your situation.
5. Is a $1,000 day rate the same as an equivalent salary of around $260,000?
Not really. A day rate often compensates for things a salary already includes, paid leave, superannuation and job security, so the headline figure isn’t a clean, like-for-like comparison. Once it’s annualised more conservatively and weighed against continuity questions a lender will ask, the practical assessed income is usually meaningfully lower than a simple multiplication would suggest.
6. Does the remaining length of my contract affect my borrowing capacity?
Yes, though it’s considered alongside your rate rather than in isolation. A longer remaining term generally gives a lender more confidence, while a shorter term can still be supported with a renewal letter or a track record of previous contracts being renewed. A lower rate with a long, well-documented history can sometimes present more favourably than a higher rate with little time or continuity behind it.
7. Will contract income mean I pay a higher interest rate?
Not automatically. If your documentation and history are strong enough for a mainstream lending pathway, your rate can be the same as a salaried borrower’s. A rate premium tends to apply where your specific circumstances mean an alternative-documentation or specialist product is the more realistic route, rather than simply because your income arrives as a contract rate.
The Bottom Line
A contract rate and a salary aren’t the same kind of number, and treating them as directly comparable is where most of the confusion in this topic starts. Your headline rate, your realistic annualised income once non-billable time is accounted for, and the figure a specific lender will actually use, are three genuinely different things, and understanding the gap between them is what lets you approach a home loan application with accurate expectations. Whether you’re comparing a contracting opportunity against your current salary, or you’ve already made the switch and want a realistic sense of your borrowing capacity, working through these numbers properly, rather than relying on a simple multiplication, is what separates a rough guess from a genuinely informed decision.
