Financial decision guide and interactive simulator

Home loan affordability calculator

Can I afford this home after tax and normal living costs?

What this calculation is designed to show

Compare the full monthly housing cost with take-home income, essential expenses and existing debt. Increase the interest rate before relying on the result, because an affordable introductory payment can become uncomfortable when rates change.

How to test the decision

Try the asking price and deposit first, then add rates, levies, insurance and maintenance. A useful result is the cash left after every housing cost—not simply whether a bank may approve the loan.

Using the result responsibly

Change one important assumption at a time and compare a cautious case with the expected case. The interactive calculator below updates from the values you enter. Its output is an educational estimate, not financial, tax, legal or investment advice.
