Investment Property Loan Calculator
Work out the repayment, the gross rental yield, and the LVR on an investment purchase before you talk to anyone. Enter the property value, your deposit, an indicative rate, the term, and the weekly rent. Toggle between principal-and-interest and interest-only to see how the monthly cost shifts. It is a planning number, not an approval.
A scope note first. Windsor Finance is a finance broker, not a lender. We arrange investment property finance through a panel of Australian bank and non-bank lenders, and our focus is investment, development, commercial, and SMSF property lending rather than standard owner-occupier home loans. This tool is built for property investors sizing a purchase or refinance.
What this calculator estimates
The tool runs the standard amortisation maths on the loan (the property value less your deposit) and returns the monthly repayment, the gross rental yield, and the LVR. Switch the repayment type to interest-only and the monthly figure drops to the interest on the balance, with the principal left to clear later or on refinance.
Gross rental yield is the annual rent as a percentage of the property value. It is a useful first screen on income, but it is a gross figure. Rates, insurance, management, and maintenance all sit outside it, so the real net return is lower. Treat every output as indicative. The lender confirms your real position on application.
Indicative only
- Residential investment LVR reaches up to around 80%, with LMI above that line.
- Gross yield excludes rates, insurance, management, and maintenance.
- Windsor Finance is a broker, not a lender.

Investment lending in the Australian context
Investor lending is assessed more tightly than owner-occupier lending. Lenders test your servicing against a buffer, commonly around 3 percentage points above the actual rate, and they read rental income cautiously, often at 70% to 80% of the gross figure to allow for vacancy and costs. So the repayment a calculator says you can carry and the amount a lender will advance are frequently different numbers.
Investment property loans for an individual are consumer credit and are regulated under the National Consumer Credit Protection Act, with responsible lending obligations attached. Lending held in a company or trust for a business or investment purpose is generally assessed differently. A broker will confirm which applies to your structure.
This is where a calculator reaches its limit. It cannot read your income evidence, the property type, or how a lender will treat the rent. A broker takes one packaged enquiry to a panel of bank and non-bank lenders, then places it with the lender most likely to fund it cleanly. Windsor Finance is a finance broker, not a lender. Lenders approve and lend.
