How to determine your mortgage payment
Calculating your mortgage payment is essential when budgeting for a new home or refinance. In Australia, it depends on three key factors:
Principal: The total amount borrowed.
Interest rate: The lender’s charge: fixed, variable or split.
Loan term: Usually 25–30 years. Shorter terms mean higher repayments but less interest overall.
Even small rate differences can greatly affect repayments, a 0.5% lower rate could save tens of thousands over 30 years. HeyNest connects you with independent brokers who compare lenders to find your most accurate and affordable mortgage payment.

Factors that impact mortgage payment
Beyond principal, rate and term, several elements shape your final payment:
Repayment frequency: Weekly or fortnightly payments reduce overall interest and shorten your loan.
Loan type:
Interest-only loans start cheaper but don’t reduce debt.
Principal and interest loans cost more initially but build equity.
Offset account: Savings in your offset account reduce the loan balance on which interest is charged. This lowers total interest and shortens your loan term, even if the regular payment stays the same.
A local broker can help combine these features for the best balance between payment size and total savings.

Getting accurate payment estimates
Online calculators offer a quick snapshot, but formal quotes are far more precise. To get an accurate figure:
Check your LVR: A lower Loan to Value Ratio (under 80%) usually earns a better rate.
Include fees: Setup costs, ongoing fees and Lenders Mortgage Insurance (LMI) all affect total repayments.
Broker assessment: A broker reviews your full financial profile and uses lender software to calculate a true repayment figure, factoring in real rates and costs.

Frequently asked questions
Does paying fortnightly determine a lower monthly mortgage payment?
No, the payment amount is the same, but paying fortnightly reduces the total interest paid over the life of the loan.
What is the fastest way to determine my maximum affordable payment?
The fastest way is to use a borrowing capacity calculator or, better yet, consult an Australian mortgage broker for a pre-assessment.
Is LMI included when I determine mortgage payment?
LMI is typically added to your total loan amount (capitalised), so yes, it indirectly increases the principal, which then increases your payment.
