Understanding the Numbers

Estimate repayments and buying costs, compare loans and the effect of additional repayments, learn why borrowing capacity varies and see what your budget could leave for a deposit or extra repayments.

These online tools are a starting point for a conversation, not necessarily the final answer. Book a pre-qualification appointment and we'll work through figures tailored to you.

Loan Repayments

What a loan costs per week, fortnight or month - and the total interest over its life.

Calculator assumptions

  • Interest is compounded at the repayment frequency; lenders generally accrue daily and debit monthly, so a lender schedule may differ slightly.
  • The rate is assumed constant for the whole term.
  • Fees, charges, offset accounts and redraw are not included.
  • Principal and interest: the loan is fully repaid over the term.

Important information

These calculations are estimates only and are based on the information you enter and the assumptions shown. They are not a quote, offer of credit or credit advice. Actual figures and eligibility will depend on lender policy and a formal assessment of your circumstances.

Beyond the online estimate

Borrowing Capacity

A borrowing capacity tab without a calculator? That's not a mistake. Online calculators can produce a number in seconds, but that number can be misleading because lenders don't all assess your circumstances in the same way.

Why the answer can vary so much

Your borrowing capacity can differ by hundreds of thousands of dollars between lenders. Each applies different policies to income, expenses, debts and commitments, so the same information can produce a very different result.

The broker difference

A clearer, lender-aware borrowing range

I match your circumstances - including overtime, bonuses, allowances and self-employed income - with relevant lender policies. I call this being pre-qualified: giving you a clearer borrowing range before you make major decisions.

What can change the answer?

Income treatment How lenders treat overtime, bonuses, allowances,
commissions and casual income.
Self-employed income How long you have traded and which financial
periods a lender will accept.
Living expenses Different benchmarks and how your declared
household spending is assessed.
Existing commitments Credit-card limits, other loans and dependants,
plus ongoing financial commitments.
Lender appetite + pricing Some lenders may offer greater capacity, sometimes at a higher rate or cost.

Pre-qualification provides indicative guidance only. It is not a pre-approval, an offer of credit or a promise to lend. Any application remains subject to verification, lender policy and formal assessment.

Extra Repayments

See how paying more can cut your loan term and reduce your total interest paid.

Calculator assumptions

  • The extra amount is paid every repayment, starting immediately, for the life of the loan.
  • The interest rate is assumed constant.
  • Fixed-rate loans often cap extra repayments - check your loan contract.
  • Fees and charges are not included.

Important information

These calculations are estimates only and are based on the information you enter and the assumptions shown. They are not a quote, offer of credit or credit advice. Actual figures and eligibility will depend on lender policy and a formal assessment of your circumstances.

Calculator assumptions

  • Both loans are modelled as principal-and-interest loans with monthly repayments.

  • Total cost includes principal, interest, upfront fees and the monthly fee entered.
  • Other charges, offset benefits, redraw and package discounts are not included.

Calculator assumptions

All amounts are entered manually. Buying costs are treated as one-off expenses and added to the property purchase price. The requested loan is deducted from that total to estimate the funds required to complete the purchase. If the requested loan exceeds the combined purchase price and costs, the funds required figure is shown as $0. Ongoing loan repayments, grants, rebates and other funding sources are not included. Government and lender charges should be confirmed before purchase.

These calculations are estimates only and are based on the information you enter and the assumptions shown. They are not a quote, offer of credit or credit advice. Actual figures and eligibility will depend on lender policy and a formal assessment of your circumstances. Please ask your lender, broker, conveyancer or solicitor and the relevant government authority to confirm the final costs for your transaction.

Budget Planner

See what may be left after expenses and repayments to build a home deposit or pay down your loans sooner.

Take-home income

Use the amount received after tax, HECS/HELP and other payroll deductions.

Living expenses

Include regular household and personal spending.

Liability repayments

Enter repayments, not the outstanding account balance.

Monthly net income$0
Monthly living expenses$0
Monthly liability repayments$0

Monthly budget summary

Net income received$0
Living expenses$0
Liability repayments$0
Estimated monthly surplus$0

Calculator assumptions

Amounts within each section are assumed to use the frequency selected for that section and are converted to a monthly equivalent. Net income means money actually received after tax, HECS/HELP and other payroll deductions. The result assumes all entered income is available to meet the entered living expenses and liability repayments. Irregular expenses, future changes and unentered commitments are not included.

Important information

This calculator provides a general estimate based only on the figures entered. It is not financial advice or an assessment of borrowing capacity. Lenders may assess income, expenses and liabilities differently and may apply minimum expense benchmarks. The amount actually remaining will depend on your circumstances and spending.
