Construction Loan Calculator

We are quite disappointed with all the construction loan calculators that are available in Australia. They are either hard to understand or a simple repayments calculator that had nothing to do with the different stages of construction, progress payments or drawdown amount. This means you cannot effectively plan the finances for your construction loan!

So we built our own!

Introducing Reservoir Finance’s Construction Loan Calculator where we can help you understand the interest repayments at each stage of your construction project! It does require knowledge of the construction loan process. If you’re stuck on how to use it, scroll past for more detailed instructions. Alternatively, feel free to contact us via phone or using the form below.

Using the Reservoir Finance construction loan calculator

To use this calculator, you will need to have the details of your fixed construction contract ready. This will help you complete the necessary figures for each stage of construction, the building process and the progress payments related to it.

The Loan Required section is based on the calculated Loan Amount Required section at the top of the calculator. You will need to provide an estimate percentage in order to reflect the correct progress payment for each stage.

You should also have an estimated schedule from your builder indicating how many days each stage will take.

The output of this calculator will inform you the interest expenses for each stage.
