How this estimate works
Enter all income and outgoings as monthly amounts. Exclude any rent that ends when you buy and include ongoing ownership costs in your expenses. The starting 3 percentage point buffer illustrates a higher-rate scenario. Lenders may use different buffers, expense benchmarks and income rules, so an actual offer can differ.
Example amounts illustrate the calculation. Replace them with your own figures or quotes.
How is borrowing power estimated?
Subtract monthly expenses, existing debt repayments and any cash you want to keep spare from take-home pay. The calculator converts the amount left for repayments into a loan balance using your interest rate, buffer and loan term.
