Loan affordability rules of thumb (and when they fail)

Banks optimize approval risk. You optimize sleep and optionality.

Educational · verify with official sources · Financial Content Team — Calcly Australia

## Use net income, stress the rate

Loan-to-income and Mortgage payment should use take-home, not offer-letter gross. Re-run payments +1–2% rate. If the budget only works at teaser rates, it does not work.

## Stack risk

A clean mortgage plus a quiet car loan plus BNPL is still a stack. List all fixed payments with Debt comparison. Approval is not the same as wisdom — especially under model au-payg-super-not-employee assumptions used for education on this site.
