Use this mortgage affordability calculator to estimate a home-price ceiling from income, debts, property costs and your own monthly limit.
Personal home-price ceiling
The lowest credible payment limit controls the illustrative price, not the largest amount available from one ratio.

How the affordability ceiling is calculated
The calculator uses the lowest of a gross-income housing limit, a total-debt limit and the personal complete-payment ceiling. After property costs, it converts the available instalment into financing principal and a home-price estimate.
- This is a household planning ceiling, not an approval estimate.
- Property costs are deducted before solving for financing principal.
- Cash to close and post-purchase reserves need separate checks.
Start with a complete monthly payment
Property assessment, insurance or takaful, maintenance charges and a repair allowance compete with the financing instalment. Enter recurring property costs before solving for a price.
A listing price that fits principal and interest alone may fail once those costs are known. Replace allowances with property-specific statements and quotations during the search.
The lowest credible limit should control the search
Approval capacity, complete payment and personal comfort answer different questions.

Keep lender capacity separate from household comfort
Gross-income ratios are broad diagnostics, not approval rules. The personal ceiling should come from take-home cash after food, transport, care, protection, savings and irregular costs.
The lower limit should control the search. If a lender later offers more, that does not create more household capacity or make the post-purchase reserve optional.
Test the cash side before using the price
The result does not prove that the down payment, transaction costs and reserve are available. Run the price through the closing-cost and down-payment tools before treating it as a working range.
Stress-test a higher rate and higher property costs. A useful search ceiling survives the difficult case instead of requiring perfect conditions every month.

Common questions about this calculator
Is the home-price result a bank approval amount?
No. It is a planning estimate from user-entered limits and generic ratios. Financial institutions apply their own current assessment and documentation rules.
Why include a personal payment ceiling?
A lender-oriented ratio uses gross income, while the personal ceiling can reflect take-home cash, care, transport, saving and other household priorities.
