How lenders assess self-employed borrowing power
Lenders generally treat self-employed and ABN income more conservatively than a PAYG payslip. The typical approach averages the last two years of tax returns or Notices of Assessment, adds back non-cash items like depreciation, and often applies a shading or discount to income that looks volatile or is heavily reliant on one client.
What this calculator models
- Two-year Notice of Assessment averaging for self-employed income
- Common add-backs such as depreciation and one-off expenses
- An income shading adjustment for variable or contract-based earnings
- A resulting indicative borrowing power figure to compare against a standard PAYG assessment
