How does this calculator work?
Borrowing capacity starts with an illustrative maximum monthly payment after other debt obligations. Your lender will use its own affordability and underwriting criteria.
A practical what-if example
Higher interest rates reduce the principal supported by the same monthly payment. Try different terms and leave a cushion for insurance and unexpected costs.
Important costs and limitations
The estimate excludes down payment, living expenses, lender income adjustments and insurance premiums.
Which inputs make the biggest difference?
Start by adjusting household take-home income / month, then other debt payments / month and target debt-to-income ratio (%). These are editable assumptions rather than mandatory averages. Changing one slider at a time lets you see which inputs matter most. Use values from your own bills, estimates or accounts where available rather than treating the defaults as market benchmarks.
Compare a conservative and an ambitious scenario
First create a conservative estimate with your known numbers. Then increase other debt payments / month and check target debt-to-income ratio (%) along with other relevant items (annual interest rate (%) term (years)). This yields a more useful range than a single unexplained prediction. Save or note both results when planning next steps.
Using your estimate in the real world
This money and property tool provides a transparent planning estimate. Calculations run in your browser without registration. It is designed for comparison and personal planning, not a binding quote or financial, legal or tax advice. Check local regulations and actual provider terms before committing.
Common mistakes to avoid
Do not mix up household take-home income / month and other debt payments / month: the units and periods may differ. Watch out for annual versus monthly amounts, percentage assumptions and costs already included elsewhere. Enter each expense only once and verify the calculations shown in the results panel.
Why can your actual outcome differ?
Two similar situations may produce different outcomes due to target debt-to-income ratio (%) or charges outside the model. Instead of making unsupported promises, the calculator displays editable assumptions. Prices, platform fees and local tax rules can change, so use the result as an initial estimate only.
Frequently asked questions
Do existing debts reduce my borrowing capacity?
Yes. Car loans, credit card obligations and other recurring repayments reduce the amount available for a new mortgage. Lenders may calculate affordability differently.
Does a larger down payment mean I can buy a more expensive home?
It can reduce the amount you need to borrow, but it does not remove income and affordability checks. Keep room in your budget for closing costs, repairs and moving.
