Results
The output below preserves the MoneySmart three-line summary so inclusive and exclusive prices stay explicit.
Starting from $1,100.00 as a GST-inclusive amount, the GST component is $100.00.
What to watch
- Inclusive and exclusive conversion is directly reusable for fee comparisons and settlement-cost presentation.
- Business-expense normalization can support self-employed borrower evidence and cashflow assessment.
- Keeping tax-separated prices explicit helps downstream recommendation and quote explanations stay clearer.
How these estimates work
- This calculator assumes a standard taxable sale with 10% GST.
- To work out the cost including GST, the amount exclusive of GST is multiplied by 1.1.
- To work out the GST component from an inclusive price, the amount is divided by 11.
- GST-free and input-taxed sales are outside the scope of this calculator.
