The user receives precise monthly repayment figures and maximum borrowing capacity based on Australian tax rules, living costs, and lender assessment buffers, avoiding generic AI guesses.
The agent extracts the user's income, expenses, existing debts, and desired loan parameters. It then calls the estimate_repayments tool to calculate monthly costs and total interest, and estimate_borrowing_power to determine loan capacity by applying Australian tax calculations and lender buffer rates. The agent presents the results with clear attribution to the Arthr calculators.

Prompt: I want to buy a house in Australia. My household income is $150,000, living costs are $60,000/year, and I have $20,000 in existing repayments. I'm looking at a $800,000 loan at 6% interest for 30 years. Calculate my monthly repayments and estimate how much I can actually borrow based on these figures.
