Construction calculator


This is an estimate of an amount you may be able to borrow, based on the information and interest rate you input. If you change any of the information, including the interest rate, you will obtain a different result. The result does not include any applicable fees. This is not an offer of credit, and you should not rely on it. Any amount you may be able to borrow can only be determined once you submit a full application to us and we assess your application using our credit criteria applicable at that time. The application process considers more information than you have input here, and so any amount you may be able to borrow may differ from this estimate. This estimates is indicative only and actual costs and the amount you could borrow may vary based on a number of factors including loan purpose. Before acting on the results of this estimation you should seek professional advice and contact your local RAMS Home Loan Specialist. Credit criteria, fees, charges, terms, conditions and eligibility requirements apply. RAMS home loans are not available for foreign borrowers residing outside Australia. *Suitable for residential properties, other than strata titles.

The Cordell Sum Sure calculator takes the answers you input (or confirm, as applicable) and analyses them against construction industry data collated by CoreLogic to generate an estimated rebuild cost of the improvements on your property. Use of the Cordell Sum Sure calculator and any estimated rebuild cost provided by it may not be appropriate for you and you will need to assess the suitability of this estimate given your knowledge of your property. A number of qualifications apply to the estimated rebuild cost, which are set out in the full set of terms and conditions accepted by you prior to your use of the Cordell Sum Sure Calculator.
