Loan Repayment Calculator
Frequently Asked Questions
What does the loan repayment calculator do?
The loan repayment calculator estimates your regular loan repayments and total interest payable based on the loan amount, interest rate, loan term, repayment frequency, offset balance, and any additional repayments you enter. It is designed to help you understand how different repayment strategies may affect your loan over time.
Note: The information provided by the calculator is intended to provide illustrative examples based on stated assumptions and your inputs. Results are estimates only and must not be relied upon.
Does the calculator include fees and charges?
Generally no. The calculator focuses on principal and interest repayments (as well as interest only loan repayments) only and does not typically include fees such as establishment fees, package fees, monthly account fees, or ongoing costs.
These costs can affect the true cost of a loan and should be considered separately.
How does the calculator treat offset account balances?
The calculator assumes that the offset balance you enter is held consistently over time and reduces the interest calculated on your loan balance accordingly. In reality, offset balances often fluctuate due to spending, income timing, and lifestyle factors.
Actual interest savings may differ from the calculator result.
Can the calculator show the impact of making extra repayments?
Yes. The calculator allows you to include additional monthly repayments and estimates how these may reduce your loan term and total interest payable.
However, the calculator assumes additional repayments are made consistently for the duration entered and does not account for changes in behaviour or cash flow.
Does the calculator assume the interest rate stays the same?
Yes. The calculator assumes the interest rate you enter remains unchanged for the life of the loan or the period modelled. Variable rates can change at any time, and fixed rates only apply for the fixed period selected, if you have (or intending to apply for) a fixed rate loan.
Future rate movements are not reflected in the results.
Will making extra repayments always save interest?
Extra repayments and offset balances can reduce interest payable over time, but the benefit depends on consistency, loan structure, and lender rules. Some loans limit additional repayments, particularly during fixed rate periods.
The calculator does not assess product suitability or lender restrictions.
Can I rely on this calculator to decide how much extra to repay?
The calculator is a helpful planning tool but should not be relied upon as the sole basis for financial decisions. It does not consider emergency funds, future expenses, or broader financial goals.
A personalised review can help ensure additional repayments align with your overall strategy.
Does the calculator model redraw or withdrawals from offset?
No. The calculator does not model future redraws or withdrawals from an offset account. It assumes balances and repayment behaviour remain consistent.
Any changes to these assumptions will affect actual outcomes.
Is this calculator providing financial or credit advice?
No. The calculator provides general information only and does not constitute financial advice, credit advice, or a recommendation.
You should seek tailored advice before acting on the results.
What should I do after using the loan repayment calculator?
The calculator is best used to explore scenarios and understand the potential impact of offset balances and extra repayments. If you would like help structuring your loan or confirming what is realistic for your circumstances, a discussion with a mortgage broker is recommended.
Note: The information provided by the calculator is intended to provide illustrative examples based on stated assumptions and your inputs. Calculations are estimates only and it is advised that you consult with a mortgage broker about your specific circumstances.
