Assumptions and limitations

This is an indicative estimate, not a credit decision, a pre-approval or any lender’s own calculator. Each lender applies its own policy, and your actual borrowing capacity depends on that policy, a full credit assessment and your circumstances. Subject to lender approval.

  • Take-home income. Before-tax salaries have 2026-27 resident income tax, the 2% Medicare levy and the low income tax offset applied; a HELP/HECS debt adds the compulsory repayment. An after-tax salary is used as entered.
  • Extra income is shaded. Rental income counts at 80% and bonuses, commissions and overtime at 80%, then tax is taken off at your marginal position. Other income counts in full and is treated as taxable.
  • Living expenses. The higher of what you enter and a household benchmark (the Household Expenditure Measure, by adults, dependants and income) is used. The benchmark is a floor lenders apply, not a statement about how you live. Rent that continues after the loan is added on top.
  • Commitments. Home-loan and personal-loan repayments as entered, plus 3.8% a month of your total credit-card limit (the limit, not the balance).
  • Assessment rate and term. The product rate shown in the results plus the 3% serviceability buffer APRA, the banking regulator, requires (never below a 5.25% floor), on a principal-and-interest loan over the term you choose (10 to 30 years). Repayments are shown at the product rate itself.
  • Debt-to-income ceiling. The estimate is capped at 6 times gross household income and rounded down to the nearest $1,000.
  • Purchase side. Stamp duty is the current schedule for the state your postcode sits in (South Australia when none is entered), with first-home relief applied when you tell us it is your first home. Lenders Mortgage Insurance above 80% LVR is an industry approximation by LVR band, not an insurer’s quote. Purchase price is what the deposit stretches to after duty and LMI.
