A friend in Australia recently sought my advice about the usefulness or otherwise of a Mortgage Calculator. My friend was looking at refinancing her mortgage in Australia but was unsure as to the long-term benefits of such a move. She had heard about a mortgage calculator that could compare products and wanted to run her own scenario. We tracked down one mortgage calculator but this was a simple “how much can I borrow?” mortgage calculator which required you to input your salary and other liabilities or debts to work out your borrowing capacity. The fact is that while such a mortgage calculator will give you an idea of how much you might borrow in Australia, other factors will be taken into account by the lender when assessing your loan.
