Hospital rosters can make a doctor’s take-home pay much higher than base salary. On-call payments, weekend shifts, overtime and allowances may contribute to a home-loan assessment, but they should never be assumed to count in full at every lender. The key questions are whether the income is verifiable, recurring and likely to continue—and what the proposed lender’s current policy allows.
Separate base and variable income
Start by showing base pay on its own. Then list each additional source and the period it covers. A simple table helps:
| Source | What to show | Question to resolve |
|---|---|---|
| Base salary | Contract and recent payslips | Is the role permanent or fixed-term? |
| Overtime | Payslips and roster pattern | How consistent is it? |
| On-call and penalties | Payslips and employer explanation | Is it expected to continue? |
| Allowances | Payslip description and conditions | Is it income, reimbursement or expense-related? |
Do not annualise a single unusually busy fortnight without explaining the normal roster. Keep recent payslips that show a representative period, plus year-to-date figures and an employer letter if requested. If a rotation is ending, disclose that rather than implying its pattern will continue unchanged.
Why lenders may calculate different amounts
APRA’s residential mortgage lending guidance says lenders should verify income and adjust temporary or uncertain amounts. It notes that bonuses, overtime and other variable income are often discounted in prudent assessments. That is a general prudential framework, not a fixed calculation for every applicant.
Some lenders publish more specific policies for eligible healthcare workers. For example, Westpac states that certain eligible healthcare professionals could have 100% of overtime and allowances assessed as income, subject to its conditions. This does not mean Westpac—or any other lender—will automatically count all additional pay for every doctor. The actual role, income history, product and full credit assessment still matter.
Consider your own budget, not just the lender’s figure
Even if a lender accepts a high proportion of documented variable income, ask whether you would be comfortable with the repayments if your roster changed or you took leave. A registrar moving hospitals, a doctor entering private practice or a specialist reducing sessions may experience a different cash-flow pattern after the loan begins. Leave space for ordinary living costs and an emergency buffer.
What to ask before submitting an application
- Which components of my pay will this lender consider, and over what history?
- Will an allowance be treated as income or reimbursement?
- How does a fixed-term contract or future rotation affect the assessment?
- What evidence would resolve any uncertainty before a formal application?
- Is the resulting loan competitive on total cost, not only borrowing capacity?
A broker can compare current policies against your evidence. Read the home loans for doctors page or arrange a conversation.General information only. No lender is obliged to count all overtime or allowances; assessment and approval depend on current policy and individual circumstances.

Compare lenders on how they assess your real pay pattern, then choose a repayment budget that still feels sustainable.

Frequently asked questions
Will lenders count 100% of a doctor’s overtime?
Not automatically. Treatment varies by lender, history and type of payment.
Can an allowance improve borrowing capacity?
It may if a lender accepts it as ongoing income, but evidence and policy conditions matter.
