MORTGAGE YEARS
Calculate your monthly $500k mortgage payment
A $500,000 home loan over 30 years requires knowing your likely monthly repayment before you commit. Your payment depends mainly on the interest rate, along with fees and the loan structure your lender applies. Understanding these inputs helps you budget accurately and assess real affordability. What determines your repayment:
The rate your lender offers
P&I vs interest-only repayment structure
Fees that may be added to your loan (e.g., service fees, LMI)
Since lenders each apply different rates, fees and features, the most reliable estimate comes from comparing actual offers. HeyNest connects you with a broker who calculates accurate repayments using current market data for your $500k loan.

Factors that change your $500k monthly cost
While interest rate is the main driver, several variables can increase or reduce your final repayment amount on a $500,000 mortgage over 30 years. Key influences include:
Deposit size and LVR: A larger deposit can avoid LMI and unlock better rates.
Offset accounts: Money in an offset account reduces the interest charged on your loan.
Fixed vs variable rates: Fixed rates provide stability; variable rates move with the market.
Payment frequency: Weekly/fortnightly payments can reduce interest and shorten the term.
With so many moving parts, choosing the right structure is easier with expert support. HeyNest matches you with a local broker who tailors your loan to reduce your long-term repayment costs.
