The calculator provided is a Genworth calculator typically used for mortgage insured deals. It is quite conservative and the banks have their own calculators that are a little more generous for sub 80% LVR deals. Are you a single borrower or have a family? Other debts? There are quite a few questions I would ask my clients before giving them a figure.
If you are a sub-contractor you are classed as self-employed. How long have you been a subby? Most banks will want to see the last two years tax returns. ANZ only need one and their calculator is one of the more generous ones. If your latest tax return is the higher one I would just get the latest return and head to ANZ.
