Mortgage calculator
How ready are you to start house hunting?
A practical checklist to help you prepare for a first-home conversation.
Preparing for your first home
Use this checklist to identify what to organise before a lending conversation: deposit information, budget, documents and your next steps.
Example and common question
Illustrative example: If your deposit is documented but you have not reviewed your spending, start with a realistic budget. You can speak with an adviser before finding a property.
Does completing the checklist mean I qualify?
No. It measures preparation only. A lender still needs to assess your application and any eligibility requirements.
Preparation steps completed
—A starting point for your adviser conversation.

Get your numbers together
Use the deposit planner and repayment calculator, then talk with us before committing to a purchase.
How this estimate works
No personal details are collected by this checklist and no lender eligibility is assessed. A completed checklist does not mean pre-approval. Finance conditions, lawyer review and property due diligence still matter.
Estimates only. Not personalised financial advice or lending approval. Your lender's calculation and eligibility criteria may differ. Our disclosure statement.
Mortgage calculator
What changes when you refix?
Compare your current and proposed repayments over the same remaining loan term.
Refixing explained
Refixing chooses a new fixed rate when your current fixed period ends. Compare quoted rates using your current balance and remaining loan term.
Example and common question
Illustrative example: On $600,000 over 25 years, changing from 6.5% to 5.5% reduces the estimated monthly payment from $4,051 to $3,685. These are illustrative rates, not current offers.
Should I restart the loan term?
A longer term may lower the payment but increase lifetime interest. Start with your remaining term and discuss changes with your adviser.
Estimated monthly change
—For principal-and-interest repayments, using the same loan term.
A fresh rate, not a new 30-year term
Compare on your remaining term. Extending the term can lower repayments while increasing lifetime interest.
How this estimate works
Standard monthly principal-and-interest amortisation. Weekly equivalent is monthly change × 12 ÷ 52, not a lender’s exact weekly schedule. Rates are assumed unchanged for 12 months. Fees, offset balances and extra payments are not included.
Estimates only. Not personalised financial advice or lending approval. Your lender's calculation and eligibility criteria may differ. Our disclosure statement.
Mortgage calculator
What loan fits your repayment budget?
Explore a repayment-based estimate. This does not assess what a lender will approve.
A repayment budget, explained
This tool works backwards from a monthly payment to estimate a loan size. Set aside a buffer and allow for living costs, other debts and home ownership expenses.
Example and common question
Illustrative example: If $3,500 is available each month and you reserve $500, the model uses $3,000 for repayments. Increasing the rate or shortening the term reduces the loan that payment supports.
Is this a borrowing approval?
No. A lender also assesses income, expenses, credit history, deposit and the property. Treat this as a conversation starter.
Repayment-based loan estimate
—Based only on the repayment budget, rate and term entered.
This is not borrowing approval
A lender will assess your income, spending, debts, dependants, deposit, property and policy requirements. A budget-based figure can be much higher than an approved loan.
How this estimate works
Reverse calculation of a standard monthly principal-and-interest payment. Available payment = budget minus buffer, floored at zero. No income verification, debt-to-income assessment or lender servicing model is applied. Rates are held constant. Fees and future changes are excluded.
Estimates only. Not personalised financial advice or lending approval. Your lender's calculation and eligibility criteria may differ. Our disclosure statement.
Mortgage calculator
How could a split loan compare?
Compare two loan portions against a single rate, while keeping the same overall loan term.
Splitting your mortgage
A split mortgage puts portions of your loan on different rates or fixed periods. This lets you compare payments and interest without changing the overall loan term.
Example and common question
Illustrative example: A 50/50 split of a $600,000 mortgage creates two $300,000 portions. Enter each quoted rate and compare their combined payment with the single-rate option.
Does this predict rates at the next refix?
No. Rates stay constant during the comparison. Fixed periods show scheduling only; future rates and break fees are not predicted.
Estimated split monthly repayment
—Two portions combined, with the same remaining loan term.
Rate reviews and flexibility
Splitting can spread rate-review dates, but may affect refinancing flexibility and break costs. It does not guarantee lower rates.
How this estimate works
Both portions are modelled as principal-and-interest loans over the same remaining term. Fixed periods describe rate-review timing, not the loan repayment term. Entered rates are held constant for the comparison even after a fixed period ends. Actual refix rates are unknown. This model excludes floating, offset and revolving-credit balances, fees and extra payments.

How could the rental cash flow look?
Estimate rental cash flow before tax, allowing for vacancy, operating costs and loan repayments.
Rental cash flow explained
Rental cash flow is rent received less operating costs and loan payments. Allow for vacant weeks, management, insurance, rates and maintenance.
Example and common question
Illustrative example: Rent of $700 a week for 50 occupied weeks gives $35,000 a year. An 8% management fee is $2,800. Other costs and mortgage payments still need to come out of that income.
Is cash flow the same as profit?
No. Principal repayments affect cash flow but reduce debt. This estimate excludes tax, changes in property value and sale proceeds.
Estimated annual cash flow
—Before tax, excluding capital gains and purchase costs.
Cash flow and profit are different
Principal repayments build equity but still use cash. Tax, depreciation and capital growth are not modelled. Interest-only terms require lender approval and future repayments may rise.
How this estimate works
Annual rent = weekly rent × (52 minus vacant weeks). Management fees are a percentage of rent received. Operating costs are entered by you and should exclude loan repayments and the separately entered management fee. Principal-and-interest costs use monthly amortisation; interest-only assumes a constant loan balance for a full year. No tax calculations are performed. Ask your accountant about your circumstances.
