How to calculate your $700K monthly repayment

Before committing to a $700,000 home loan over 30 years, it’s essential to understand what drives your monthly repayment. The biggest factor is the interest rate you’re offered, and even small changes can dramatically affect your long-term cost. What determines your repayment:

  • The loan amount ($700k)

  • The interest rate

  • The 30-year term

  • Whether you pay monthly, weekly or fortnightly

Different lenders use different rates and fee structures, so accurate repayment figures come from real comparisons, not generic calculators. HeyNest connects you with an independent broker who checks live rates and secures a competitive deal for your $700,000 mortgage.

Factors affecting your final $700K mortgage payment

Your total cost isn’t just about the interest rate. The way your loan is structured can raise or lower your repayments over time. Key influences:

  • LMI: If your deposit is under 20%, this added cost can increase your effective loan balance.

  • Loan features: Offset and redraw can reduce interest, though some lenders charge extra for them.

  • Fixed vs variable rates: Fixed offers repayment stability; variable moves with the market.

  • Fees: Application fees, annual package fees and settlement costs impact the real cost of borrowing.

Because these details can change your monthly repayment significantly, comparing them properly is crucial. A HeyNest-connected broker breaks down the true cost and negotiates the most suitable structure for you.

Frequently asked questions

Does the 30-year term mean I pay twice as much interest?

Not necessarily twice, but a significantly longer term means you pay substantially more total interest compared to a 15- or 20-year term.

Is it better to fix my rate to stabilize the $700,000 mortgage payment?

Fixing your rate provides certainty and budget stability, protecting you from rate hikes, but you may miss out if variable rates drop.

Does a larger deposit directly reduce the final monthly payment?

Yes, a larger deposit reduces the principal loan amount, which is the most direct way to lower your monthly repayment.
