Buying costs and loan repayment calculator

Add up the cash you need to buy a home: your deposit plus the costs on top of the price. If you type an interest rate, it also shows what the loan could cost each month.

The calculators work in your browser. Nothing you type is sent to RealSearch, saved, or added to the web address.

The purchase

The cash you will put in towards the price.

Costs on top of the price

Type the amount from your state revenue office's calculator, or from your conveyancer. This page does not work it out.

Include lenders mortgage insurance here if it applies to you.

A loan (optional)

Leave empty if you only want the cash you need.

How this is worked out
  1. Loan amount = purchase price minus deposit.
  2. Cash you need up front = deposit + stamp duty + legal fees + inspections + loan fees + moving + other costs. You type each cost in. Nothing is looked up or guessed.
  3. Deposit as a share of the price = deposit ÷ purchase price × 100.
  4. Monthly repayment (principal and interest) = loan × r ÷ (1 − (1 + r)^−n), where r is the yearly interest rate ÷ 1200 and n is the number of months. If the rate is 0, it is the loan ÷ n. Interest only = loan × yearly rate ÷ 1200.
  5. Repayment per week = repayment per month × 12 ÷ 52. Repayment per year = repayment per month × 12.
What this leaves out
  • Stamp duty (transfer duty). It depends on your state, the price and who you are, and the rules change. Type in the amount from your state revenue office's own calculator or your conveyancer.
  • Government grants, concessions and schemes, which change often. The First home buyers page lists the official sources.
  • Lenders mortgage insurance, if your deposit is small. Ask your lender, and add it under 'Other costs'.
  • Rates, insurance, strata levies and repairs after you move in.
  • Changes in interest rates. The repayment uses one rate for the whole loan.
  • Tax. This is not financial, legal or tax advice.
