Important information
This calculator provides estimates only and is not a quote, credit approval, borrowing-capacity assessment or financial advice. It assumes the interest rate remains unchanged and interest is compounded at the selected repayment frequency. It excludes lender-specific daily interest calculations, expense benchmarks, income shading, credit limits, unentered fees, taxes, account charges, rate changes and lender rounding. A balloon or residual is an additional final payment. Actual repayments, borrowing capacity and eligibility depend on the lender, product and your circumstances.
For independent information about calculator assumptions and home-loan estimates, see the Australian Government’s Moneysmart mortgage calculator guidance.
How the Finance Repayment Calculator Works
The finance repayment calculator uses the information you enter to estimate regular repayments and the overall cost of the selected finance structure. It does not assess eligibility or compare lender products.
Select the finance type
Choose Asset Finance, Home Loan P&I, Home Loan Interest Only, or Indicative Borrowing Capacity.
Enter your assumptions
Add the amount, annual interest rate, loan term and repayment frequency. Asset finance also allows a deposit, financed fees and balloon.
Review the estimate
See the regular repayment, estimated total interest and total loan repayments. Change an input to compare another scenario.
What Each Calculation Shows
Asset Finance
The amount financed is the asset price less the deposit or trade-in, plus any fees added to the loan. When a balloon or residual is entered, regular repayments are calculated on the basis that this amount remains payable at the end.
Home Loan Principal & Interest
Each regular repayment includes interest and an amount that progressively reduces the loan principal. The estimate assumes the same rate and repayment frequency for the full loan term.
Home Loan Interest Only
During the interest-only period, repayments cover estimated interest without reducing principal. The calculator then estimates the higher principal-and-interest repayment needed over the remaining term.
Repayment Frequency
Weekly calculations use 52 periods per year, fortnightly calculations use 26, and monthly calculations use 12. Interest is compounded at the selected frequency for this estimate.
Indicative Borrowing Capacity
This section subtracts entered living expenses and existing monthly debt repayments from household net income. It converts the remaining monthly amount into an indicative loan size at the entered interest rate plus the assessment buffer. It is not a lender assessment.
Asset Borrowing Capacity
This section estimates the maximum asset finance amount supportable by the entered monthly surplus, rate, term and balloon. The expected asset-finance rate is used by default. An optional stress-test margin may be entered for scenario testing, but no fixed margin is assumed.
Understanding the Results
Amount financed
The amount borrowed after deducting the deposit and adding any fees being financed.
Regular repayment
The estimated amount payable each week, fortnight or month, depending on the selected frequency.
Balloon or residual
A separate lump sum that remains payable at the end of an asset finance contract.
Total interest
The estimated total loan repayments, including any balloon, less the original amount financed.
Total loan repayments
All estimated regular repayments plus any balloon. An asset deposit is paid separately and is not included.
Interest-only period
A period when estimated repayments cover interest but do not reduce the outstanding principal.
Assessment-rate buffer
An additional percentage added to the entered interest rate when testing an indicative borrowing capacity. A lender may use different rates, floors and policies.
Frequently Asked Questions
How accurate is this finance repayment calculator?
The mathematical estimate is based on the values entered and the stated compounding assumptions. Actual lender repayments may differ because lenders can calculate interest daily, apply different rounding, include fees or use product-specific methods.
Can I calculate car and equipment finance repayments?
Yes. Select Asset Finance and enter the asset price, deposit or trade-in, financed fees, annual interest rate, term, repayment frequency and any balloon or residual.
What is a balloon payment?
A balloon is a lump sum due at the end of the finance term. It can reduce regular repayments, but it increases the amount remaining at the end and may increase total interest. It usually needs to be paid, refinanced or addressed through another arrangement, subject to lender approval.
Does the deposit form part of the loan repayments?
No. For asset finance, the deposit reduces the amount financed and is treated as an upfront contribution. It is not included in the displayed total loan repayments.
What is the difference between P&I and interest-only?
Principal-and-interest repayments progressively reduce the amount borrowed. Interest-only repayments generally cover interest without reducing principal, so repayments can increase when the loan changes to principal and interest.
Why might my lender quote a different repayment?
A lender may use daily interest, a different compounding convention, a first or final irregular repayment, lender fees, account charges or different rounding. Rates may also change for variable-rate products.
Are fees included?
Only the amount entered in “Fees added to the loan” is included, and that field applies to Asset Finance. Establishment fees, ongoing charges, government costs and other expenses are excluded unless specifically entered.
Does using the calculator mean I qualify for finance?
No. The calculator does not assess borrowing capacity or eligibility. Finance is subject to application, lender assessment, lending criteria, fees, charges, terms and conditions.
How is the indicative borrowing capacity calculated?
The calculator subtracts entered monthly living expenses and existing monthly debt repayments from household net monthly income. It then calculates the principal that could be serviced by that remaining amount over the selected term at the entered rate plus the assessment buffer.
Why could a lender’s borrowing capacity be different?
Lenders may verify income differently, apply tax and income shading, use minimum living-expense benchmarks, assess credit-card limits rather than balances, apply interest-rate floors or buffers, and account for dependants and product-specific policies. The result on this page is therefore only an initial scenario estimate.
How is asset borrowing capacity estimated?
The calculator uses the monthly amount remaining after entered expenses and commitments. It estimates the finance principal supportable over the selected term at the expected asset-finance rate, plus any optional stress-test margin you choose to enter, while allowing for the balloon. No fixed asset-finance buffer is assumed.
